A full integration would require registering an opencode plugin with a `permission.ask` hook plus bridging Claude CLI's `--permission-prompt-tool` through a local MCP server; opencode's `permission.ask` hook is reactive (it only intercepts opencode-initiated asks, not provider-initiated ones), so a non-trivial bridge is required. Contributions welcome. +- **No native opencode permission dialog for CLI-initiated asks**: when `skipPermissions: false`, this provider now handles Claude `can_use_tool` control requests itself (auto allow/deny). That prevents deadlocks and enables policy control, but it still does not open opencode's built-in permission modal. Full parity requires opencode core exposing a provider-facing permission bridge plus a CLI control-request adapter. ## Publishing diff --git a/src/claude-code-language-model.ts b/src/claude-code-language-model.ts index c99e0ba..33dbe6e 100644 --- a/src/claude-code-language-model.ts +++ b/src/claude-code-language-model.ts @@ -10,6 +10,7 @@ import type { import { generateId } from "@ai-sdk/provider-utils" import type { ClaudeCodeConfig, + ControlRequestBehavior, ClaudeStreamMessage, ReasoningEffort, } from "./types.js" @@ -114,6 +115,101 @@ export class ClaudeCodeLanguageModel implements LanguageModelV3 { return "default" } + private controlRequestBehaviorForTool(toolName: string): ControlRequestBehavior { + const configured = this.config.controlRequestToolBehaviors + if (configured && toolName) { + const direct = configured[toolName] ?? configured[toolName.toLowerCase()] + if (direct === "allow" || direct === "deny") return direct + + const lower = toolName.toLowerCase() + for (const [key, behavior] of Object.entries(configured)) { + if (key.toLowerCase() === lower && (behavior === "allow" || behavior === "deny")) { + return behavior + } + } + } + + return this.config.controlRequestBehavior ??

Aligns with opencode core's mergeDeep semantics so the bridge sees the same effective config opencode does. - Discovery aligned with opencode core: walks parents up to the worktree root, loads opencode.json + opencode.jsonc at each level, includes home-dir .opencode/, OPENCODE_CONFIG ordered before project walk-up. - Hot-reload: bridgeOpencodeMcp now returns {path, hash}. The cached claude subprocess is evicted between turns when the hash differs, so on-disk MCP edits are picked up without restarting opencode or starting a new chat. - Runtime overlay: opencode's /mcps UI toggle is in-memory only (client.mcp.connect/disconnect, never written to disk). Plugin now captures the SDK client and calls client.mcp.status() each turn, overlaying connected->enabled and anything else->disabled onto the disk merge before hashing. - Tests: new test-bridge.ts with 23 cases via node:test + tsx covering merge semantics, walk-up boundaries, jsonc precedence, runtime overlay, and hash stability. --- src/claude-code-language-model.ts | 87 +++++- src/index.ts | 46 ++- src/mcp-bridge.ts | 447 +++++++++++++++++++++++------- src/opencode-types.ts | 19 ++ src/runtime-status.ts | 49 ++++ src/session-manager.ts | 31 ++- src/types.ts | 14 + test-bridge.ts | 415 +++++++++++++++++++++++++++ 8 files changed, 987 insertions(+), 121 deletions(-) create mode 100644 src/runtime-status.ts create mode 100644 test-bridge.ts diff --git a/src/claude-code-language-model.ts b/src/claude-code-language-model.ts index 95a3b83..946ba42 100644 --- a/src/claude-code-language-model.ts +++ b/src/claude-code-language-model.ts @@ -16,7 +16,8 @@ import type { } from "./types.js" import { mapTool } from "./tool-mapping.js" import { getClaudeUserMessage } from "./message-builder.js" -import { bridgeOpencodeMcp } from "./mcp-bridge.js" +import { bridgeOpencodeMcp, type RuntimeMcpStatus } from "./mcp-bridge.js" +import { getRuntimeMcpStatus } from "./runtime-status.js" import { getActiveProcess, spawnClaudeProcess, @@ -111,22 +112,35 @@ export class ClaudeCodeLanguageModel implements LanguageModelV3 { } /** - * Build the combined `--mcp-config` list: user-configured paths plus the - * auto-bridged opencode MCP config (when enabled and present) and the - * proxy MCP scratch file (when proxyTools are enabled). + * Build the combined `--mcp-config` list and return both the list and the + * hash of the bridged opencode MCP block (or null when bridging is off / + * yields nothing).

Identity-checked against package.json name and description, skips if user lists the unscoped name in their plugin config, never self-deletes.

Sonnet routinely takes 5+ seconds to transition from a chat-text block to its next tool_use block, which guillotined the stream mid-turn with reason=stop and zero usage. Reframe the timer as a wire-inactivity watchdog: reset on every line received from the CLI, fire only after extended silence on stdout. Bump the default threshold from 5s to 60s for normal flow; the abort grace path keeps a short 5s window by passing it explicitly. The session-reuse hang the timer was originally added to catch (CLI emits content but never sends a result) is still covered.

placeholders and guard drain race on result Two bugs caused MCP servers to disappear from Claude CLI's view and proxy tool calls to time out: 1. {env:VAR} placeholders not substituted in bridged MCP config. translateServer wrote the raw spec.environment / spec.headers through to the Claude CLI --mcp-config file, so any server using opencode's interpolation syntax received the literal string '{env:VAR}' as its credential value.

The plugin no longer emits the empty block (which was triggering Anthropic 400s like `cache_control cannot be set for empty text blocks`). +- **Smart incomplete-turn continuation.** By default, the plugin keeps the current opencode stream open and feeds Claude CLI a small internal continuation message when Claude emits a `result` after reasoning/tool activity without a useful visible answer.

Resets on every line received, so long mid-turn pauses (Sonnet between text-end and the next tool_use, for example) are tolerated. On a user-initiated abort, the watchdog shortens to 5 seconds. - **Per-iteration usage.** When the CLI internally retries with tools, the plugin only counts the last iteration's usage so opencode's context accounting stays accurate. diff --git a/package.json b/package.json index 3b02e99..2b20039 100644 --- a/package.json +++ b/package.json @@ -20,7 +20,7 @@ "build": "tsup", "dev": "tsup --watch", "typecheck": "tsc --noEmit", - "test": "tsx --test test-bridge.ts test-broker.ts" + "test": "tsx --test test-bridge.ts test-broker.ts test-auto-continue.ts" }, "dependencies": { "@ai-sdk/provider": "^3.0.8", diff --git a/src/claude-code-language-model.ts b/src/claude-code-language-model.ts index 0e16189..b6f71bf 100644 --- a/src/claude-code-language-model.ts +++ b/src/claude-code-language-model.ts @@ -91,6 +91,121 @@ function hasNewUserContent( return false } +const AUTO_CONTINUE_MAX_ATTEMPTS = 8 +const AUTO_CONTINUE_MAX_ELAPSED_MS = 10 * 60 * 1000 +const AUTO_CONTINUE_NO_PROGRESS_LIMIT = 2 + +const AUTO_CONTINUE_PROMPT = + "Continue the task from where you stopped.

Mid -task narration like 'Implementing now. Updated the search index.' hit those keywords reliably and short-circuited the auto-continue to 'final-answer' — STOP — even though the next text block was a mid-task pause and the user still expected more work. Track lastVisibleText separately: reset on each new text content_block start, append on text deltas. Pass it through AutoContinueSnapshot. Final-answer detection now considers only the most recent text block, which is the actual candidate end-of-turn sentence. Question / blocker detection still uses the accumulated text — a question raised earlier in the turn should still block auto-continue. Also add file-based logging at $XDG_DATA_HOME/opencode-claude-code/ plugin.log (defaults to ~/.local/share/opencode-claude-code/plugin.log) so NOTICE/WARN/ERROR are observable without depending on DEBUG=opencode-claude-code or stderr redirection.

Result: the gate let the prompt through but the message builder emitted the '(empty)' sentinel, so Claude CLI saw a no-op turn and ended it — forcing the user to press 'continue' between every proxy tool call. Symmetric fix: when iterating recent messages, also extract tool-result parts from tool-role messages. Matches hasNewUserContent's shape so the two functions agree on where to find tool-results. Tests: 4 new in test-get-claude-user-message.ts cover tool_result emission, multiple results per message, sentinel fallback when a tool-role message has no tool-result parts, and mixed user+tool content.

This works across every Claude 4 family model the CLI supports. + +What you see is a **summary** of the model's thinking, not the raw chain-of-thought. Anthropic [stopped exposing raw thinking on the Claude 4 family](https://platform.claude.com/docs/en/build-with-claude/extended-thinking#summarized-thinking) and ships a server-generated digest instead. For Claude Opus 4.7 specifically, [thinking content is omitted from responses by default](https://platform.claude.com/docs/en/about-claude/models/whats-new-claude-4-7#thinking-content-omitted-by-default); the plugin opts back in by passing `--thinking-display summarized` on every spawn. Claude Code CLI 2.1.142+ is required for that flag to take effect; older CLIs skip it silently. + +### Reasoning effort variants + +Each model exposes `low` / `medium` / `high` / `xhigh` / `max` variants. Picking one injects the corresponding Claude CLI thinking keyword (e.g. `(ultrathink)` for `max`) into the user message.

From that point on, this.config.cwd was frozen, defeating the process.cwd() lazy fallback that previously made workspace-aware behavior work. Workspace switches in opencode's UI never updated a value set at plugin init, so Claude CLI stayed pinned to the first-opened workspace. - Move captured directory + resolution helpers into runtime-status.ts (existing cycle-break module). - Add resolveSpawnCwd(configured) with priority chain: 1. explicit options.cwd (user override always wins) 2. live process.cwd() when usable (restores lazy resolution) 3. captured directory from plugin init (rescues macOS GUI at /) 4. process.cwd() as final fallback - Stop baking opencodeProjectDirectory into mergedOptions in index.ts. - Swap the two spawn sites in claude-code-language-model.ts to use resolveSpawnCwd(). - Add test-cwd-resolution.ts (9 tests) covering every branch via a testable resolveSpawnCwdFrom inner function. - Document the rule in AGENTS.md so future me doesn't reintroduce. Does NOT fix desktop GUI launches where opencode does not chdir on workspace switch (process.cwd() stays at /). That requires tier-two work (event-hook listener or runtime directory query).

Opt-in: default `proxyTools` stays the existing four (Bash/Edit/Write/WebFetch).

Mechanism mirrors the existing four proxies: Claude calls `mcp__opencode_proxy__task` via --mcp-config, the parked HTTP request drains into the AI SDK stream as a tool-call with `toolName: "task"` (matching opencode's native tool name, providerExecuted: false), opencode runs its task tool, and extractPendingProxyResult matches by callId to resolve the parked MCP call. The 10-minute PROXY_CALL_TIMEOUT_MS cap applies. Long subagent runs near that ceiling are a known constraint until per-tool timeouts exist.

State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Verified compatible with opencode v1.15.0 (audit 2026-05-16). `ProviderV2` hook gained an optional `ctx` arg we ignore; `McpStatus` expanded to 5 variants but `enabled: status === "connected"` in `mcp-bridge.ts` still collapses non-connected to `false` correctly. opencode's `tools` argument to `doStream` is intentionally unused — Claude CLI only sees its own built-ins plus MCP servers bridged via `--mcp-config`, so opencode-native tools like `task_status` never reach the model and need no `mapTool` entry. Re-audit at the next opencode minor bump. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session.

Ignore it quietly; do not treat it as an error. - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry. They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. +- Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id. Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's. Empirically confirmed 2026-05-16 via subagent `ses_1d16d3bb4ffeOI5QUWZzBKDsSL`. - Verified compatible with opencode v1.15.0 (audit 2026-05-16). `ProviderV2` hook gained an optional `ctx` arg we ignore; `McpStatus` expanded to 5 variants but `enabled: status === "connected"` in `mcp-bridge.ts` still collapses non-connected to `false` correctly. opencode's `tools` argument to `doStream` is intentionally unused — Claude CLI only sees its own built-ins plus MCP servers bridged via `--mcp-config`, so opencode-native tools like `task_status` never reach the model and need no `mapTool` entry. Re-audit at the next opencode minor bump. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4.

The tool_use was collapsed to a faint `_Asking: _` line in three code paths — dropping every option, header, and any question past the first. Replaced with formatAskUserQuestion(): a shared renderer that emits all questions with headers, enumerated options + descriptions, and a single/multi-select reply hint as visible markdown (same approach as ExitPlanMode; opencode has no native structured ask-question executor to proxy through). 2. The CLI control gate auto-allowed AskUserQuestion, letting the headless Claude CLI resolve its own question with no TTY (fabricated or empty answer) and proceed on a guess. controlRequestBehaviorForTool now hard-denies AskUserQuestion (explicit controlRequestToolBehaviors config still overrides), with a specific deny message telling the model to stop and wait for the user. The tool_use is still streamed and rendered, and the turn stops for a real answer. Re-applied on upstream v0.4.23 after the duplicate local Task-proxy commits were dropped (upstream shipped the identical feature as 9a31ae8 / PR #5, authored by galvani).

Without a unique affinity, two sessions sharing the same process.cwd()+model can collide on the same session key and resume the wrong Claude CLI conversation. Inject input.sessionID from the chat.params hook into providerOptions as opencodeSessionID, before the agent guard. resolveSessionAffinity() reads it as a fallback when the header is absent, so each opencode session gets an isolated session key and separate Claude CLI process.

When non-tool blocks (text, thinking) precede a tool_use, that index does not align with the toolCalls array, so partial_json chunks updated the wrong (or no) entry. 2. On each input_json_delta chunk, `tc.args = JSON.parse(partial_json)` either replaced args with a slice or silently swallowed the chunk on parse failure. Partial chunks never accumulated into a full object. 3. The Claude CLI child process was not killed on spawn error and was only relying on the readline close path on the happy case. Fix: - Track streaming tool_use blocks in a Map keyed by content-block index, accumulating partial_json into an `inputJson` string buffer. - Parse `inputJson` at content_block_stop and push the result to toolCalls. Log a warning on JSON parse failure instead of swallowing. - Add a cleanup() that kills the child on error, on result, and on readline close.

From d03e33f17214c7ba6d5a827a1288dcde01a9a995 Mon Sep 17 00:00:00 2001 From: Jan Kozak Date: Mon, 25 May 2026 15:59:49 +0200 Subject: [PATCH 116/295] fix(provider): inject full model definitions via config hook MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit opencode loads plugin `provider.models` hooks before extending the provider database from config. For plugin-only providers — those that don't exist in the public models-dev catalog, e.g. `claude-code` — the `provider.models` hook bails (the `database[providerID]` lookup is empty), so model fields (limit, cost, family, name, capabilities, release_date) stay at their schema defaults of 0/empty/false. Symptom: the session-context-usage indicator and context tab in the web UI show 0 / no percentage / no cost / no model name for any claude-code session, even though message tokens are populated correctly. Other providers (deepseek, anthropic, openai) render fine because their metadata is in models-dev. `configModelsForProvider` already exists and produces models in the flat config schema opencode expects; it was wired into the multi-account expand path but not the default single-provider path. This change adds it to the default config-hook output so opencode sees real limits/costs/etc. when it builds the database from config. Also: `configModelsForProvider` previously only read `api.npm` / `api.url` from `existing` config — it did not preserve user-defined `variants`. Switching to it as the single source of models would silently drop custom variants users had added to their `opencode.json`. Updated the function to merge `existing.variants` on top of the default-model variants (user values win on key collision), so user overrides survive the round-trip. (Reported by Gemini Code Assist on the initial draft of this PR.) Verified by hitting `/config/providers` before and after — claude-code now reports `limit.context`, `cost.input`, `family: "opus"`, `capabilities.reasoning: true`, etc. instead of zero/empty defaults.

Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id. Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's.

Re-audit at the next opencode minor bump. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`).

ClaudeSession.tailTurn re-emits transcript records; claude-session-wrapper adapts it to the ActiveProcess contract and synthesizes a result line so the existing finish branch runs unchanged. Headless stays the default. Also fix an orphan tool-result for skipped internal tools on the non-partial branch (register toolCallsById only inside !skip, mirroring the streaming path).

Do not delete or override `CLAUDE_CODE_DISABLE_THINKING`, `CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING`, or explicit `CLAUDE_CODE_SHOW_THINKING_SUMMARIES` values. - Reasoning stream parts are only started after the first non-empty `thinking_delta`. This prevents empty Thinking rows when the CLI opens a thinking block but streams no text. +- opencode's own reasoning features (e.g. v1.17.0 "Added Claude Fable reasoning support", vLLM interleaved `reasoning` field) live in opencode's **native** Anthropic/vLLM runtime, which this plugin deliberately bypasses by routing through the `claude` CLI. There is nothing to "switch to" — the plugin implements reasoning itself (reasoning variants → thinking keyword + `--thinking`/`--thinking-display` flags → `thinking_delta` forwarding), and any model defined with `reasoning: true` (including `claude-fable-5`) inherits the full path automatically. Do not re-investigate adopting opencode's native reasoning; it would mean abandoning the CLI wrapper. +- Model display names carry a list-price multiplier as a `(N×)` suffix (`src/models.ts` `defineModel`, via the `multiplier` field): haiku 1×, sonnet 3×, opus 5×, fable 10×, mythos 10×. These are exact ratios of published per-token price vs Haiku (input and output ratios coincide), so Fable/Mythos = 2× Opus 4.8. opencode has no native multiplier field, so the suffix is the only way it surfaces in the picker; it's display-only and model resolution still keys off `id`. `test-config-models.ts` asserts the suffixed names — update both if the format changes. +- `opusCost` in `src/models.ts` is the real Opus 4.5+ standard price ($5/M in, $25/M out — corrected from a stale legacy $15/$75). Haiku ($1/$5), Sonnet ($3/$15), and Fable/Mythos ($10/$50) were already correct. If you add a model, set its cost from the published standard (not Fast Mode) pricing so the `(N×)` suffix stays consistent. - `signature_delta` is expected encrypted thinking metadata. Ignore it quietly; do not treat it as an error. - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry. They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded.

There is nothing to "switch to" — the plugin implements reasoning itself (reasoning variants → thinking keyword + `--thinking`/`--thinking-display` flags → `thinking_delta` forwarding), and any model defined with `reasoning: true` (including `claude-fable-5`) inherits the full path automatically. Do not re-investigate adopting opencode's native reasoning; it would mean abandoning the CLI wrapper. - Model display names carry a list-price multiplier as a `(N×)` suffix (`src/models.ts` `defineModel`, via the `multiplier` field): haiku 1×, sonnet 3×, opus 5×, fable 10×, mythos 10×. These are exact ratios of published per-token price vs Haiku (input and output ratios coincide), so Fable/Mythos = 2× Opus 4.8. opencode has no native multiplier field, so the suffix is the only way it surfaces in the picker; it's display-only and model resolution still keys off `id`. `test-config-models.ts` asserts the suffixed names — update both if the format changes. - `opusCost` in `src/models.ts` is the real Opus 4.5+ standard price ($5/M in, $25/M out — corrected from a stale legacy $15/$75). Haiku ($1/$5), Sonnet ($3/$15), and Fable/Mythos ($10/$50) were already correct. If you add a model, set its cost from the published standard (not Fast Mode) pricing so the `(N×)` suffix stays consistent. +- Billing context (researched 2026-06-10, documented in README "Billing change: June 15, 2026"): from 2026-06-15 Anthropic bills `claude -p` / Agent SDK usage (which is exactly what this plugin spawns via `--print`) against a separate monthly Agent SDK credit on subscription plans (Pro $20 / Max 5x $100 / Max 20x $200), not normal plan limits; API-key auth is unaffected. Same day, `claude-sonnet-4-20250514` / `claude-opus-4-20250514` retire (not registered here, but pass-through overrides could hit them). Fable 5 is included free on plans only through 2026-06-22; after that it needs usage credits. No code change needed — this is account-side billing the plugin can't influence. - `signature_delta` is expected encrypted thinking metadata. Ignore it quietly; do not treat it as an error. +- `WebSearch` with the default `"claude"` routing must NOT be forwarded as a tool-call part. opencode has no `WebSearch` registry entry, and (at least as of opencode v1.17.0) the AI SDK rejects unknown tool names with "Model tried to call unavailable tool" even when `providerExecuted: true` — users saw `⚙ invalid` rows on every CLI-internal web search (fixed after v0.8.0). `mapTool` returns `skip: true` for it, and both tool_use sites in `claude-code-language-model.ts` render the query as a `> **Web search:** …` text line instead (gated by `isWebSearchTool` + `isWebSearchHandledByCli` from `tool-mapping.ts`). Explicit opencode-tool routing (`webSearch: ""`) still forwards with `executed: false`. Tests in `test-tool-mapping.ts`. - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry. They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id.

Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session.

Tests live in `test-cwd-resolution.ts`. - `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. +- Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The system prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); without it interactive sessions never see opencode agent prompts. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). (5) The `Bun.Terminal` capability gate falls back to headless silently. (6) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`).

There is nothing to "switch to" — the plugin implements reasoning itself (reasoning variants → thinking keyword + `--thinking`/`--thinking-display` flags → `thinking_delta` forwarding), and any model defined with `reasoning: true` (including `claude-fable-5`) inherits the full path automatically. Do not re-investigate adopting opencode's native reasoning; it would mean abandoning the CLI wrapper. - Model display names carry a list-price multiplier as a `(N×)` suffix (`src/models.ts` `defineModel`, via the `multiplier` field): haiku 1×, sonnet 3×, opus 5×, fable 10×, mythos 10×. These are exact ratios of published per-token price vs Haiku (input and output ratios coincide), so Fable/Mythos = 2× Opus 4.8. opencode has no native multiplier field, so the suffix is the only way it surfaces in the picker; it's display-only and model resolution still keys off `id`. `test-config-models.ts` asserts the suffixed names — update both if the format changes. - `opusCost` in `src/models.ts` is the real Opus 4.5+ standard price ($5/M in, $25/M out — corrected from a stale legacy $15/$75). Haiku ($1/$5), Sonnet ($3/$15), and Fable/Mythos ($10/$50) were already correct. If you add a model, set its cost from the published standard (not Fast Mode) pricing so the `(N×)` suffix stays consistent. -- Billing context (researched 2026-06-10, documented in README "Billing change: June 15, 2026"): from 2026-06-15 Anthropic bills `claude -p` / Agent SDK usage (which is exactly what this plugin spawns via `--print`) against a separate monthly Agent SDK credit on subscription plans (Pro $20 / Max 5x $100 / Max 20x $200), not normal plan limits; API-key auth is unaffected.

Same day, `claude-sonnet-4-20250514` / `claude-opus-4-20250514` retire (not registered here, but pass-through overrides could hit them). Fable 5 is included free on plans only through 2026-06-22; after that it needs usage credits. Confirmed failure mechanism: the 400 `Third-party apps now draw from your extra usage...` corresponds to a `rate_limit_event` with `{rateLimitType:"five_hour", overageStatus:"rejected", overageDisabledReason:"org_level_disabled"}` under OAuth subscription auth, so org-level overage/extra usage being disabled can reject requests that do not fit the remaining rolling window. URL redaction was tested and reverted; the opencode repo URL is not the trigger. Interactive mitigation: live bisection showed this plugin's own CLI/AGENTS/continuation prompt succeeds, while opencode's forwarded system prompt payload can trip the usage gate on constrained subscription accounts. Interactive mode therefore intentionally omits the forwarded opencode system prompt by default. Real account-side fixes remain: enable overage/add extra usage, wait for the 5-hour window reset, switch account/org/plan, or use API-key auth. - `signature_delta` is expected encrypted thinking metadata. Ignore it quietly; do not treat it as an error. - `WebSearch` with the default `"claude"` routing must NOT be forwarded as a tool-call part. opencode has no `WebSearch` registry entry, and (at least as of opencode v1.17.0) the AI SDK rejects unknown tool names with "Model tried to call unavailable tool" even when `providerExecuted: true` — users saw `⚙ invalid` rows on every CLI-internal web search (fixed after v0.8.0). `mapTool` returns `skip: true` for it, and both tool_use sites in `claude-code-language-model.ts` render the query as a `> **Web search:** …` text line instead (gated by `isWebSearchTool` + `isWebSearchHandledByCli` from `tool-mapping.ts`). Explicit opencode-tool routing (`webSearch: ""`) still forwards with `executed: false`. Tests in `test-tool-mapping.ts`. - `tool-input-delta` parts must only be forwarded for tool calls whose `tool-input-start` was actually emitted. opencode's AI SDK bridge (`packages/opencode/src/session/llm/ai-sdk.ts`) resolves delta/end names via `state.toolNames[event.id] ?? "unknown"`; a delta for an unseen id creates a permanently-pending part with `tool: "unknown"` that the TUI renders as `⚙ unknown`. Skipped tools (ToolSearch, TaskCreate/TaskUpdate, CLI-internal WebSearch, AskUserQuestion, ExitPlanMode, proxy tools) stream `input_json_delta` like any other tool_use, so the streaming site in `claude-code-language-model.ts` gates delta forwarding on a `started` flag set only when the input-start part went out (fixed after v0.8.1). Keep accumulating `inputJson` unconditionally — the skip-path text rendering (AskUserQuestion/ExitPlanMode/WebSearch) depends on it. @@ -52,7 +52,7 @@ - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4. Tests live in `test-cwd-resolution.ts`. - `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message.

The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message.

(2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process.

Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. KNOWN ISSUE (open as of v0.9.0, shipped experimental): with `interactive: true`, starting a *fresh* opencode session under Bun can leave the TUI blank/unresponsive before the first keystroke — i.e. BEFORE any `doStream`/interactive spawn runs, so `plugin.log` does not capture it. `opencode --continue` (resumed session) works, and once a session is live the transport is stable and reused (verified 2026-06-10: this very session ran on interactive, spawned once, reused for ~25 min). The child `claude` PTY is isolated (`Bun.spawn` `terminal:{}` at `claude-session-bun.ts:205`, output captured to a buffer, only echoed to real stdout in `debug`), so terminal contention is ruled out as the cause.

Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4. Tests live in `test-cwd-resolution.ts`. - `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. +- `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`).

Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's. Empirically confirmed 2026-05-16 via subagent `ses_1d16d3bb4ffeOI5QUWZzBKDsSL`. - Verified compatible with opencode v1.15.0 (audit 2026-05-16). `ProviderV2` hook gained an optional `ctx` arg we ignore; `McpStatus` expanded to 5 variants but `enabled: status === "connected"` in `mcp-bridge.ts` still collapses non-connected to `false` correctly. opencode's `tools` argument to `doStream` is intentionally unused — Claude CLI only sees its own built-ins plus MCP servers bridged via `--mcp-config`, so opencode-native tools like `task_status` never reach the model and need no `mapTool` entry. Re-audit at the next opencode minor bump. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4. Tests live in `test-cwd-resolution.ts`. -- `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. +- `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`.

Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. Two reinforcing guards were added after v0.9.1: (1) the deny message explicitly states it is **not a cancellation** and forbids the model from saying the question was cancelled/skipped/declined — this kills the "the user cancelled, so I'll proceed" rationalization the model otherwise narrates; (2) a turn-local latch `AutoContinueState.sawAskUserQuestion`, set when `formatAskUserQuestion` renders, makes `shouldAutoContinueIncompleteTurn` return `{continue:false, reason:"question"}` for the rest of the turn. Without the latch, a short non-`?` trailing line after the question (e.g. "I'll go with the first option.") looked like an incomplete turn, and the auto-continue nudge made the model proceed with no operator input — the exact "I never interacted and it answered itself" symptom. Latch test in `test-auto-continue.ts`. - `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`). Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. diff --git a/src/claude-code-language-model.ts b/src/claude-code-language-model.ts index 6e55910..7083509 100644 --- a/src/claude-code-language-model.ts +++ b/src/claude-code-language-model.ts @@ -208,6 +208,16 @@ interface AutoContinueState { noProgressCount: number lastSignature?: string aborted?: boolean + /** + * Latched true once AskUserQuestion is rendered this turn.

There is nothing to "switch to" — the plugin implements reasoning itself (reasoning variants → thinking keyword + `--thinking`/`--thinking-display` flags → `thinking_delta` forwarding), and any model defined with `reasoning: true` (including `claude-fable-5`) inherits the full path automatically. Do not re-investigate adopting opencode's native reasoning; it would mean abandoning the CLI wrapper. -- Model display names carry a list-price multiplier as a `(N×)` suffix (`src/models.ts` `defineModel`, via the `multiplier` field): haiku 1×, sonnet 3×, opus 5×, fable 10×, mythos 10×.

From September 1: switch it to `sonnetCost` ($3/$15), multiplier 3×, update the README model table + pricing paragraph and the `test-config-models.ts` assertions (name suffix becomes `(3×)`, cost fields change). The plan is to have an open PR staged with this change and merge it just before Sept 1. +- `opusCost` in `src/models.ts` is the real Opus 4.5+ standard price ($5/M in, $25/M out — corrected from a stale legacy $15/$75; Opus 5 keeps it).

New-generation entries (Sonnet 5, Opus 5) use `output: 128_000` (the models' real max output); the older entries still say 16_384 for historical reasons — raising them is a candidate follow-up, don't mix conventions within a release. - Billing context (researched 2026-06-10, documented in README "Billing change: June 15, 2026"): from 2026-06-15 Anthropic bills `claude -p` / Agent SDK usage (the plugin's default headless `--print` path) against a separate monthly Agent SDK credit on subscription plans (Pro $20 / Max 5x $100 / Max 20x $200), not normal plan limits; API-key auth is unaffected. Same day, `claude-sonnet-4-20250514` / `claude-opus-4-20250514` retire (not registered here, but pass-through overrides could hit them). Fable 5 is included free on plans only through 2026-06-22; after that it needs usage credits. Confirmed failure mechanism: the 400 `Third-party apps now draw from your extra usage...` corresponds to a `rate_limit_event` with `{rateLimitType:"five_hour", overageStatus:"rejected", overageDisabledReason:"org_level_disabled"}` under OAuth subscription auth, so org-level overage/extra usage being disabled can reject requests that do not fit the remaining rolling window. URL redaction was tested and reverted; the opencode repo URL is not the trigger. Interactive mitigation: live bisection showed this plugin's own CLI/AGENTS/continuation prompt succeeds, while opencode's forwarded system prompt payload can trip the usage gate on constrained subscription accounts. Interactive mode therefore intentionally omits the forwarded opencode system prompt by default. Real account-side fixes remain: enable overage/add extra usage, wait for the 5-hour window reset, switch account/org/plan, or use API-key auth. - `signature_delta` is expected encrypted thinking metadata. Ignore it quietly; do not treat it as an error. - `WebSearch` with the default `"claude"` routing must NOT be forwarded as a tool-call part. opencode has no `WebSearch` registry entry, and (at least as of opencode v1.17.0) the AI SDK rejects unknown tool names with "Model tried to call unavailable tool" even when `providerExecuted: true` — users saw `⚙ invalid` rows on every CLI-internal web search (fixed after v0.8.0). `mapTool` returns `skip: true` for it, and both tool_use sites in `claude-code-language-model.ts` render the query as a `> **Web search:** …` text line instead (gated by `isWebSearchTool` + `isWebSearchHandledByCli` from `tool-mapping.ts`). Explicit opencode-tool routing (`webSearch: ""`) still forwards with `executed: false`. Tests in `test-tool-mapping.ts`.

charset=UTF-8 Content-Transfer-Encoding: 8bit The CLI treats --session-id as 'create a NEW session with this UUID' and exits with 'Session ID ... is already in use' whenever a transcript for that ID already exists on disk — so every respawn that tried to continue a session (MCP hot reload, eviction, crash recovery) failed, cleared the session, and fell back to re-injecting history as text. Verified against the real CLI: --session-id reuse fails with no live process holding the ID; --resume continues under the same session ID.

Keep accumulating `inputJson` unconditionally — the skip-path text rendering (AskUserQuestion/ExitPlanMode/WebSearch) depends on it. - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry. They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). +- proxy-mcp `tools/call` responses MUST be MCP results (`{ result: { content, isError } }`), never JSON-RPC error envelopes. Claude CLI validates every `tools/call` response against the MCP result schema and rejects JSON-RPC errors as a "malformed result that failed schema validation" (seen live 2026-07-04 on broker timeouts/orphans — fixed post-0.9.2). All three error paths in `src/proxy-mcp.ts` now return results with `isError: true`: unknown tool, `result.kind === "error"` (merged into the success path), and the outer `catch` when `requestMethod === "tools/call"`. Non-`tools/call` methods (initialize, tools/list) and unparseable requests still use JSON-RPC errors, which is spec-correct. `requestId`/`requestMethod` are hoisted above the try so the catch can echo them — do not regress to `id: null`. Tests: `test-proxy-mcp.ts`. +- Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. Tests: `test-proxy-mcp.ts`, `test-broker.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id. Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's.

This was masked before the per-tool proxy timeout fix because the flat 10-minute ceiling ended the turn first; now that a long proxy-blocked task call blocks and returns successfully, resuming the reused child afterwards can leave it producing nothing (live ses_0cfc0da6 step 8 — idle, 0% CPU, no network, no error, needed a manual Esc). Add a start watchdog (doStream, fresh-turn path only; default 90s, env CLAUDE_CODE_START_WATCHDOG_MS). On first fire it respawns the child via respawnActiveProcess, which kills the wedged child but reuses its proxy server, system-prompt file, and mcp hash (handles baked into cliArgs) and appends --session-id so the conversation resumes transparently. A second fire ends the turn with an error so the next turn spawns fresh.

They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - proxy-mcp `tools/call` responses MUST be MCP results (`{ result: { content, isError } }`), never JSON-RPC error envelopes. Claude CLI validates every `tools/call` response against the MCP result schema and rejects JSON-RPC errors as a "malformed result that failed schema validation" (seen live 2026-07-04 on broker timeouts/orphans — fixed post-0.9.2). All three error paths in `src/proxy-mcp.ts` now return results with `isError: true`: unknown tool, `result.kind === "error"` (merged into the success path), and the outer `catch` when `requestMethod === "tools/call"`. Non-`tools/call` methods (initialize, tools/list) and unparseable requests still use JSON-RPC errors, which is spec-correct. `requestId`/`requestMethod` are hoisted above the try so the catch can echo them — do not regress to `id: null`. Tests: `test-proxy-mcp.ts`. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. Tests: `test-proxy-mcp.ts`, `test-broker.ts`. +- Reused-process start watchdog. A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id. Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's.

The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`). Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. +- Startup diagnostics (`src/startup-diagnostics.ts`, roadmap #3): one `NOTICE: claude-code plugin ready` block emitted once per process from the `config` hook in `index.ts`, replacing the older "registered claude-code provider(s)" notices.

It is fire-and-forget (`claude --version` is async, 5s timeout, cached) and every field is wrapped so diagnostics can never break provider registration. `describeSpawnCwd` intentionally mirrors `resolveSpawnCwd`'s priority order and a test asserts they never disagree — change both together. The MCP list is the **disk-only** merge (`mergeOpencodeMcp`, split out of `bridgeOpencodeMcp` so diagnostics never writes a scratch config): opencode's runtime status isn't settled at plugin init, so the per-turn overlay is deliberately not applied. `opencode` reads "unknown" on real opencode: as of **1.17.18** nothing reachable from a plugin carries the version (`PluginInput` has no version field; the SDK client's `app` namespace exposes only `log` and `agents` — verified live, `client.app.get()` does not exist).

A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id. Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's. Empirically confirmed 2026-05-16 via subagent `ses_1d16d3bb4ffeOI5QUWZzBKDsSL`. -- Verified compatible with opencode v1.15.0 (audit 2026-05-16). `ProviderV2` hook gained an optional `ctx` arg we ignore; `McpStatus` expanded to 5 variants but `enabled: status === "connected"` in `mcp-bridge.ts` still collapses non-connected to `false` correctly. opencode's `tools` argument to `doStream` is intentionally unused — Claude CLI only sees its own built-ins plus MCP servers bridged via `--mcp-config`, so opencode-native tools like `task_status` never reach the model and need no `mapTool` entry. Re-audit at the next opencode minor bump. +- Verified compatible with **opencode v1.18.5** (audit 2026-07-26, against the published `@opencode-ai/plugin@1.18.5` + `@opencode-ai/sdk@1.18.5` type surface, plus a live `opencode run` turn on that binary). Nothing we depend on broke, because the plugin does not import opencode's types at all — `src/opencode-types.ts` is a hand-written structural mirror, so drift is silent and has to be audited deliberately. Findings worth remembering: + - The **v1 `Hooks` surface is unchanged** where we touch it: `config`, `provider: { id, models(provider, ctx) }`, `chat.params` (output still has `options: Record` at the top level, so the "do not pre-nest under providerID" gotcha still holds). + - A **v2 plugin API** now ships alongside it (`@opencode-ai/plugin/v2`, effect + promise flavors, `PluginContext` with `aisdk` / `catalog` / `agent` / `skill` / `command` hooks). It is additive; v1 `Plugin` is still the documented entry. Migration is optional — tracked in issue #24, do not start it casually. + - `PluginInput` gained `serverUrl: URL`, `$: BunShell`, `worktree`, `experimental_workspace`. Still **no version field** (see the diagnostics gotcha). + - `McpStatus` is still the same 5 variants, so `enabled: status === "connected"` in `mcp-bridge.ts` remains correct. + - The model schema (`sdk/v2` `Model`) gained optional `cost.tiers` (`{ tier: { type: "context", size } }`) and `cost.experimentalOver200K`, and `capabilities.interleaved` gained a `field: "reasoning"` variant. All optional, so our `defineModel` output still validates. Long-context pricing for the `1_000_000`-context entries is now expressible — issue #24. + - New hooks that overlap features we hand-rolled: `tool.definition` (description/param overlay), `experimental.session.compacting` + `experimental.compaction.autocontinue` (our `/compact` detection and auto-continue nudge), `experimental.chat.system.transform`, `chat.headers`, `permission.ask`. + - CLI flags changed: `opencode run` no longer accepts `-a` as shorthand for `--agent` (spell it out in smoke tests), and gained `--variant`, `--thinking`, `--auto`, `--pure`, `--fork`, `--attach`. + - Unchanged rationale: opencode's `tools` argument to `doStream` is still intentionally unused — Claude CLI only sees its own built-ins plus MCP servers bridged via `--mcp-config`, so opencode-native tools like `task_status` never reach the model and need no `mapTool` entry. + - Re-audit at the next opencode minor bump. The `opencode` field in the startup block names the running version, so an audit starts by reading that. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4. Tests live in `test-cwd-resolution.ts`. - `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. Two reinforcing guards were added after v0.9.1: (1) the deny message explicitly states it is **not a cancellation** and forbids the model from saying the question was cancelled/skipped/declined — this kills the "the user cancelled, so I'll proceed" rationalization the model otherwise narrates; (2) a turn-local latch `AutoContinueState.sawAskUserQuestion`, set when `formatAskUserQuestion` renders, makes `shouldAutoContinueIncompleteTurn` return `{continue:false, reason:"question"}` for the rest of the turn. Without the latch, a short non-`?` trailing line after the question (e.g. "I'll go with the first option.") looked like an incomplete turn, and the auto-continue nudge made the model proceed with no operator input — the exact "I never interacted and it answered itself" symptom. Latch test in `test-auto-continue.ts`. - `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`). Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. -- Startup diagnostics (`src/startup-diagnostics.ts`, roadmap #3): one `NOTICE: claude-code plugin ready` block emitted once per process from the `config` hook in `index.ts`, replacing the older "registered claude-code provider(s)" notices.

Headless `--print` Claude Code exposes no `Agent`/`Task` dispatch tool of its own (checked through CLI 2.1.211), so the `task` proxy is the only path — but the CLI *does* expose `TaskCreate`, a todo tool, and models resolve opencode's "call the task tool with subagent: X" mention hint straight to it: a todo appears, nothing runs, and the model narrates a successful dispatch. Since Task is proxied by default (v0.10.0) this is reachable without any config. Two spawn-time countermeasures, both required: `overlayTaskProxyDescription` in `proxy-mcp.ts` injects opencode's live `task` description (carrying the "Available agent types" list, so the model stops grepping configs to verify an agent exists) onto the proxy def, and `SUBAGENT_DISPATCH_HINT` goes into the appended system prompt naming `mcp__opencode_proxy__task` as the only dispatch path. The hint's ToolSearch line is load-bearing, not padding: harnesses that defer MCP tool schemas (opencode-dcp does) leave `mcp__opencode_proxy__task` invisible while `TaskCreate` stays visible, which is the worst case for this confusion — the maintainer hit exactly that during the v0.10.0 smoke test. `TASK_PROXY_NOTE` must keep describing the real deadline (60 min, `proxyToolTimeoutMs`) and `background` mode; jknlsn's original said 10 minutes, which predated the per-tool timeouts. Only wired into `doStream`'s spawn path — `doGenerate` has no proxy wiring at all, so it deliberately has no hint. Tests: `test-subagent-hint.ts`. - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry. They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - proxy-mcp `tools/call` responses MUST be MCP results (`{ result: { content, isError } }`), never JSON-RPC error envelopes. Claude CLI validates every `tools/call` response against the MCP result schema and rejects JSON-RPC errors as a "malformed result that failed schema validation" (seen live 2026-07-04 on broker timeouts/orphans — fixed post-0.9.2). All three error paths in `src/proxy-mcp.ts` now return results with `isError: true`: unknown tool, `result.kind === "error"` (merged into the success path), and the outer `catch` when `requestMethod === "tools/call"`. Non-`tools/call` methods (initialize, tools/list) and unparseable requests still use JSON-RPC errors, which is spec-correct. `requestId`/`requestMethod` are hoisted above the try so the catch can echo them — do not regress to `id: null`. Tests: `test-proxy-mcp.ts`. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart.

Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart.

Also lands roadmap #4: a worked `multistep` subagent example showing why `permission.todowrite: allow` is load-bearing, session.child.next navigation, and sqlite queries that prove the todos landed.

The `opencode` field in the startup block names the running version, so an audit starts by reading that. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4. Tests live in `test-cwd-resolution.ts`. - `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. Two reinforcing guards were added after v0.9.1: (1) the deny message explicitly states it is **not a cancellation** and forbids the model from saying the question was cancelled/skipped/declined — this kills the "the user cancelled, so I'll proceed" rationalization the model otherwise narrates; (2) a turn-local latch `AutoContinueState.sawAskUserQuestion`, set when `formatAskUserQuestion` renders, makes `shouldAutoContinueIncompleteTurn` return `{continue:false, reason:"question"}` for the rest of the turn. Without the latch, a short non-`?` trailing line after the question (e.g. "I'll go with the first option.") looked like an incomplete turn, and the auto-continue nudge made the model proceed with no operator input — the exact "I never interacted and it answered itself" symptom. Latch test in `test-auto-continue.ts`. +- Question proxy (absorbed from @jknlsn's `47501d0` in v0.12.0) is the **opt-in alternative** to the deny/markdown path above, not a replacement for it. `"Question"` is deliberately NOT in `DEFAULT_PROXY_TOOL_NAMES` (`src/index.ts`) — enabling it disables Claude's built-in `AskUserQuestion` via `--disallowedTools` and swaps the unconditional stop-and-wait guarantee for an in-turn blocking form, which is a trade against issue #8. Keep it opt-in until it has Task's mileage; the comment above the constant records why, so do not "tidy" it into the default list. Three invariants: (1) `--disallowedTools` is computed from the **post-filter** proxy list (`enrichedProxy`), never `resolvedProxy` — `filterQuestionProxyByOpencodeSupport` drops the def on opencode builds without a `question` registry entry, and computing from the pre-filter list would disable `AskUserQuestion` while its replacement is absent, leaving the model with no question path at all. (2) `QUESTION_PROXY_HINT` must name the FULL `mcp__opencode_proxy__question`: haiku strips the MCP prefix and calls bare `question`, which opencode renders as `⚙ invalid` (same near-miss family as TaskCreate vs the task proxy). (3) `question` gets a 30-min default in `PROXY_PER_TOOL_DEFAULT_TIMEOUT_MS` because it blocks on a human reading a form; the flat 10-min ceiling rejected calls mid-answer. `fetchLiveToolInfo` does ONE `client.tool.list()` fetch feeding both the task overlay and the question gate — do not add a second fetch. Both spawn-time only, so a reused process keeps its defs. Verified live on opencode 1.18.5 (registry has `question`); a build lacking it takes the fallback silently, which the `question proxy version gate` log line makes visible. Tests: `test-proxy-mcp.ts`, `test-cli-args.ts`, `test-subagent-hint.ts`, `test-ask-user-question.ts`. - `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`). Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. @@ -95,9 +96,9 @@ Current state (refreshed 2026-07-26 after the fork/PR sweep): 1. ✅ Per-tool proxy timeouts — absorbed from @jknlsn's fork (`84f3db9`, authorship preserved) in v0.10.0: `proxyToolTimeoutMs` config, per-tool defaults (`task` 60 min), bash `input.timeout` floor.

Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`). Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. diff --git a/README.md b/README.md index e4d29c6..b14675f 100644 --- a/README.md +++ b/README.md @@ -456,7 +456,9 @@ Set `permissionMode: "plan"` to forward `--permission-mode plan` to Claude. The opencode ships a built-in `question` tool (`packages/opencode/src/tool/question.ts`) that renders a real TUI form with options and a custom-answer field — near-identical to Claude Code's `AskUserQuestion` (`multiSelect` → `multiple`). The plugin can route `AskUserQuestion` through it so the prompt becomes an actual form instead of plain text. Two modes: -### With `"Question"` in `proxyTools` (recommended on supported opencode) +### With `"Question"` in `proxyTools` (currently blocked upstream — leave it off) + +> **Known upstream breakage (opencode 1.15.x through at least 1.18.5).** opencode's `question` TUI form does not render, so the tool blocks until you interrupt the turn. This is not specific to this plugin: native providers hit it identically, and a `--pure` headless server drives the same question end to end successfully (`question.asked` → `GET /question` → `POST /question/{id}/reply` → tool completes), which isolates the fault to the TUI. Tracked upstream as [anomalyco/opencode#36604](https://github.com/anomalyco/opencode/issues/36604) with fix [PR #36603](https://github.com/anomalyco/opencode/pull/36603) (unmerged). Until that lands, enabling `"Question"` trades the working fallback below for a hang. The instructions here describe the intended behavior for when it is fixed. Add `"Question"` to `proxyTools` and grant `permission.question: allow` to the calling agent. Claude's built-in `AskUserQuestion` is disabled via `--disallowedTools`, and the plugin exposes `mcp__opencode_proxy__question` in its place. The model calls the proxy, opencode renders the form, and the operator's answers come back as arrays of selected labels. On builds that lack the `question` registry entry the def is silently dropped at spawn (version gate), and the deny/markdown fallback below applies instead.

The `opencode` field in the startup block names the running version, so an audit starts by reading that. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4. Tests live in `test-cwd-resolution.ts`. - `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. Two reinforcing guards were added after v0.9.1: (1) the deny message explicitly states it is **not a cancellation** and forbids the model from saying the question was cancelled/skipped/declined — this kills the "the user cancelled, so I'll proceed" rationalization the model otherwise narrates; (2) a turn-local latch `AutoContinueState.sawAskUserQuestion`, set when `formatAskUserQuestion` renders, makes `shouldAutoContinueIncompleteTurn` return `{continue:false, reason:"question"}` for the rest of the turn. Without the latch, a short non-`?` trailing line after the question (e.g. "I'll go with the first option.") looked like an incomplete turn, and the auto-continue nudge made the model proceed with no operator input — the exact "I never interacted and it answered itself" symptom. Latch test in `test-auto-continue.ts`. +- **The `AskUserQuestion` fallback is currently dormant in headless mode.** Probed 2026-07-26 against Claude Code CLI **2.1.211**: the name is still *known* to the CLI (`--disallowedTools AskUserQuestion` validates silently, while a bogus name prints `matches no known tool`), but the tool is **not offered to the model** under `--print` — a direct "list every tool you can call" returns `Agent, Bash, Edit, Read, ReportFindings, Skill, ToolSearch, Workflow, Write`, and `ToolSearch select:AskUserQuestion` returns nothing. It reads as a TUI-only affordance the headless surface no longer presents. Consequence: with `Question` off (the default), the model has **no** question tool at all and can only ask in prose and end the turn — which is what the deny/markdown path produced anyway, so behavior is unchanged, but do not expect `formatAskUserQuestion` or the auto-continue latch to fire on this CLI. Keep the machinery (older/newer CLIs and the interactive transport may still offer it); just do not treat "the fallback did not render" as a plugin bug without re-running the two probes above. Evidence is model self-report plus the ToolSearch miss, both on haiku. - **Question proxy is blocked upstream — leave it off.** Verified 2026-07-26 on opencode 1.18.5: the proxy delivers correctly but opencode's own `question` TUI form never renders, so an enabled `Question` costs you the working `AskUserQuestion` fallback and gives a silent hang the operator can only escape by interrupting. Proof it is not ours: (a) `github-copilot/gpt-5.5`, a native provider with the plugin nowhere in the path, fails identically (`Tool execution aborted`, `metadata.interrupted: true`, ~27 s); (b) the `part` table shows every `question` call `completed` through 2026-04-25 and every one since 2026-05-18 aborted, i.e. an opencode regression somewhere in v1.14.24…v1.15.5 (note `The user dismissed this question` is a *different*, healthy error — it means the form rendered); (c) a `--pure` (no-plugin) headless `opencode serve` drives the whole server path green — tool blocks, `question.asked` publishes, `GET /question` lists it, `POST /question/{id}/reply` completes the tool with the answer and emits `question.replied`. So the server is fine and only the TUI render is broken. Upstream: anomalyco/opencode issue **#36604** (open) with fix **PR #36603** (`hydratePending()` at TUI bootstrap, open since 2026-07-13, unmerged). Re-test when that merges; until then do not promote `Question` toward the default list, and do not spend time debugging the proxy for this symptom. - Question proxy (absorbed from @jknlsn's `47501d0`, on master after 0.11.2) is the **opt-in alternative** to the deny/markdown path above, not a replacement for it. `"Question"` is deliberately NOT in `DEFAULT_PROXY_TOOL_NAMES` (`src/index.ts`) — enabling it disables Claude's built-in `AskUserQuestion` via `--disallowedTools` and swaps the unconditional stop-and-wait guarantee for an in-turn blocking form, which is a trade against issue #8. Keep it opt-in until it has Task's mileage; the comment above the constant records why, so do not "tidy" it into the default list. Three invariants: (1) `--disallowedTools` is computed from the **post-filter** proxy list (`enrichedProxy`), never `resolvedProxy` — `filterQuestionProxyByOpencodeSupport` drops the def on opencode builds without a `question` registry entry, and computing from the pre-filter list would disable `AskUserQuestion` while its replacement is absent, leaving the model with no question path at all. (2) `QUESTION_PROXY_HINT` must name the FULL `mcp__opencode_proxy__question`: haiku strips the MCP prefix and calls bare `question`, which opencode renders as `⚙ invalid` (same near-miss family as TaskCreate vs the task proxy). (3) `question` gets a 30-min default in `PROXY_PER_TOOL_DEFAULT_TIMEOUT_MS` because it blocks on a human reading a form; the flat 10-min ceiling rejected calls mid-answer. `fetchLiveToolInfo` does ONE `client.tool.list()` fetch feeding both the task overlay and the question gate — do not add a second fetch. Both spawn-time only, so a reused process keeps its defs. Verified live on opencode 1.18.5 (registry has `question`); a build lacking it takes the fallback silently, which the `question proxy version gate` log line makes visible. Tests: `test-proxy-mcp.ts`, `test-cli-args.ts`, `test-subagent-hint.ts`, `test-ask-user-question.ts`.

There is nothing to "switch to" — the plugin implements reasoning itself (reasoning variants → thinking keyword + `--thinking`/`--thinking-display` flags → `thinking_delta` forwarding), and any model defined with `reasoning: true` (including `claude-fable-5`) inherits the full path automatically.

These are exact ratios of published per-token price vs Haiku (input and output ratios coincide), so Fable/Mythos = 2× Opus. opencode has no native multiplier field, so the suffix is the only way it surfaces in the picker; it's display-only and model resolution still keys off `id`. `test-config-models.ts` asserts the suffixed names — update both if the format changes. - **ACTION DUE 2026-09-01: bump Sonnet 5 to standard pricing.** `claude-sonnet-5` currently ships introductory pricing ($2/M in, $10/M out, `sonnet5Cost`, multiplier 2×) which expires 2026-08-31.

The premiums that *do* exist are out of scope here: Fast Mode ($10/$50 on Opus 5/4.8, and this plugin never sends `speed: "fast"`), `inference_geo: "us"` (1.1×, not a CLI flag we pass), and partner-cloud regional endpoints (10%, not our path).

Same day, `claude-sonnet-4-20250514` / `claude-opus-4-20250514` retire (not registered here, but pass-through overrides could hit them). Fable 5 is included free on plans only through 2026-06-22; after that it needs usage credits. Confirmed failure mechanism: the 400 `Third-party apps now draw from your extra usage...` corresponds to a `rate_limit_event` with `{rateLimitType:"five_hour", overageStatus:"rejected", overageDisabledReason:"org_level_disabled"}` under OAuth subscription auth, so org-level overage/extra usage being disabled can reject requests that do not fit the remaining rolling window. URL redaction was tested and reverted; the opencode repo URL is not the trigger. Interactive mitigation: live bisection showed this plugin's own CLI/AGENTS/continuation prompt succeeds, while opencode's forwarded system prompt payload can trip the usage gate on constrained subscription accounts. Interactive mode therefore intentionally omits the forwarded opencode system prompt by default. Real account-side fixes remain: enable overage/add extra usage, wait for the 5-hour window reset, switch account/org/plan, or use API-key auth. - `signature_delta` is expected encrypted thinking metadata. Ignore it quietly; do not treat it as an error. - `WebSearch` with the default `"claude"` routing must NOT be forwarded as a tool-call part. opencode has no `WebSearch` registry entry, and (at least as of opencode v1.17.0) the AI SDK rejects unknown tool names with "Model tried to call unavailable tool" even when `providerExecuted: true` — users saw `⚙ invalid` rows on every CLI-internal web search (fixed after v0.8.0). `mapTool` returns `skip: true` for it, and both tool_use sites in `claude-code-language-model.ts` render the query as a `> **Web search:** …` text line instead (gated by `isWebSearchTool` + `isWebSearchHandledByCli` from `tool-mapping.ts`).

From 5fc08147f9ff1b3aa76c74a76fc91f48be9f91d2 Mon Sep 17 00:00:00 2001 From: Collie Tsai Date: Wed, 27 May 2026 02:22:16 +0800 Subject: [PATCH 186/295] Fix ExitPlanMode approval bridge Route ExitPlanMode through opencode's native `question` tool: render the plan, end the turn on `tool-calls`, then feed the operator's answer back to the CLI as the `tool_result` for the original ExitPlanMode tool_use. That tool_result is what actually unlocks plan mode; a "yes" typed as ordinary prose never does. Absorbed from CollieIsCute's fork (8c5b583) with authorship preserved, per their go-ahead on issue #21. Maintainer adaptations on top of the original commit: - Gated behind a new `planModeQuestion` option, default off. opencode's question form does not currently render (anomalyco/opencode#36604), so an ungated bridge would trade a working text prompt for a hang. All four ExitPlanMode sites keep the legacy text path in the `else`. - Gated on the live registry too (`isPlanModeQuestionActive`): emitting a `question` tool-call on a build without that entry renders as invalid and wedges the turn. - Gate resolved in the doStream/doGenerate prologue, since the branches run in a synchronous line handler and a reused process never reaches the spawn block. - `fetchLiveToolInfo` memoized via `liveToolInfoOnce()` so the plan-mode gate shares the single `tool.list()` fetch with the proxy overlays; unresolved fetches are not memoized. - Surfaced in the startup diagnostics block. - Dropped the fork's unrelated package.json changes (`prepare` script, tsx version), kept the test-script entry.

The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. Two reinforcing guards were added after v0.9.1: (1) the deny message explicitly states it is **not a cancellation** and forbids the model from saying the question was cancelled/skipped/declined — this kills the "the user cancelled, so I'll proceed" rationalization the model otherwise narrates; (2) a turn-local latch `AutoContinueState.sawAskUserQuestion`, set when `formatAskUserQuestion` renders, makes `shouldAutoContinueIncompleteTurn` return `{continue:false, reason:"question"}` for the rest of the turn. Without the latch, a short non-`?` trailing line after the question (e.g. "I'll go with the first option.") looked like an incomplete turn, and the auto-continue nudge made the model proceed with no operator input — the exact "I never interacted and it answered itself" symptom. Latch test in `test-auto-continue.ts`. - **The `AskUserQuestion` fallback is currently dormant in headless mode.** Probed 2026-07-26 against Claude Code CLI **2.1.211**: the name is still *known* to the CLI (`--disallowedTools AskUserQuestion` validates silently, while a bogus name prints `matches no known tool`), but the tool is **not offered to the model** under `--print` — a direct "list every tool you can call" returns `Agent, Bash, Edit, Read, ReportFindings, Skill, ToolSearch, Workflow, Write`, and `ToolSearch select:AskUserQuestion` returns nothing. It reads as a TUI-only affordance the headless surface no longer presents. Consequence: with `Question` off (the default), the model has **no** question tool at all and can only ask in prose and end the turn — which is what the deny/markdown path produced anyway, so behavior is unchanged, but do not expect `formatAskUserQuestion` or the auto-continue latch to fire on this CLI. Keep the machinery (older/newer CLIs and the interactive transport may still offer it); just do not treat "the fallback did not render" as a plugin bug without re-running the two probes above. Evidence is model self-report plus the ToolSearch miss, both on haiku. - **Question proxy is blocked upstream — leave it off.** Verified 2026-07-26 on opencode 1.18.5: the proxy delivers correctly but opencode's own `question` TUI form never renders, so an enabled `Question` costs you the working `AskUserQuestion` fallback and gives a silent hang the operator can only escape by interrupting. Proof it is not ours: (a) `github-copilot/gpt-5.5`, a native provider with the plugin nowhere in the path, fails identically (`Tool execution aborted`, `metadata.interrupted: true`, ~27 s); (b) the `part` table shows every `question` call `completed` through 2026-04-25 and every one since 2026-05-18 aborted, i.e. an opencode regression somewhere in v1.14.24…v1.15.5 (note `The user dismissed this question` is a *different*, healthy error — it means the form rendered); (c) a `--pure` (no-plugin) headless `opencode serve` drives the whole server path green — tool blocks, `question.asked` publishes, `GET /question` lists it, `POST /question/{id}/reply` completes the tool with the answer and emits `question.replied`. So the server is fine and only the TUI render is broken. Upstream: anomalyco/opencode issue **#36604** (open) with fix **PR #36603** (`hydratePending()` at TUI bootstrap, open since 2026-07-13, unmerged). Re-test when that merges; until then do not promote `Question` toward the default list, and do not spend time debugging the proxy for this symptom. -- Question proxy (absorbed from @jknlsn's `47501d0`, on master after 0.11.2) is the **opt-in alternative** to the deny/markdown path above, not a replacement for it. `"Question"` is deliberately NOT in `DEFAULT_PROXY_TOOL_NAMES` (`src/index.ts`) — enabling it disables Claude's built-in `AskUserQuestion` via `--disallowedTools` and swaps the unconditional stop-and-wait guarantee for an in-turn blocking form, which is a trade against issue #8. Keep it opt-in until it has Task's mileage; the comment above the constant records why, so do not "tidy" it into the default list. Three invariants: (1) `--disallowedTools` is computed from the **post-filter** proxy list (`enrichedProxy`), never `resolvedProxy` — `filterQuestionProxyByOpencodeSupport` drops the def on opencode builds without a `question` registry entry, and computing from the pre-filter list would disable `AskUserQuestion` while its replacement is absent, leaving the model with no question path at all. (2) `QUESTION_PROXY_HINT` must name the FULL `mcp__opencode_proxy__question`: haiku strips the MCP prefix and calls bare `question`, which opencode renders as `⚙ invalid` (same near-miss family as TaskCreate vs the task proxy). (3) `question` gets a 30-min default in `PROXY_PER_TOOL_DEFAULT_TIMEOUT_MS` because it blocks on a human reading a form; the flat 10-min ceiling rejected calls mid-answer. `fetchLiveToolInfo` does ONE `client.tool.list()` fetch feeding both the task overlay and the question gate — do not add a second fetch. Both spawn-time only, so a reused process keeps its defs. Verified live on opencode 1.18.5 (registry has `question`); a build lacking it takes the fallback silently, which the `question proxy version gate` log line makes visible. Tests: `test-proxy-mcp.ts`, `test-cli-args.ts`, `test-subagent-hint.ts`, `test-ask-user-question.ts`. +- Question proxy (absorbed from @jknlsn's `47501d0`, on master after 0.11.2) is the **opt-in alternative** to the deny/markdown path above, not a replacement for it. `"Question"` is deliberately NOT in `DEFAULT_PROXY_TOOL_NAMES` (`src/index.ts`) — enabling it disables Claude's built-in `AskUserQuestion` via `--disallowedTools` and swaps the unconditional stop-and-wait guarantee for an in-turn blocking form, which is a trade against issue #8.

(2) `QUESTION_PROXY_HINT` must name the FULL `mcp__opencode_proxy__question`: haiku strips the MCP prefix and calls bare `question`, which opencode renders as `⚙ invalid` (same near-miss family as TaskCreate vs the task proxy). (3) `question` gets a 30-min default in `PROXY_PER_TOOL_DEFAULT_TIMEOUT_MS` because it blocks on a human reading a form; the flat 10-min ceiling rejected calls mid-answer. `fetchLiveToolInfo` does ONE `client.tool.list()` fetch feeding the task overlay, the question gate and the plan-mode gate — do not add a second fetch; `liveToolInfoOnce()` memoizes it per model instance for exactly that reason, and deliberately does **not** memoize an unresolved fetch (`resolved: false`) so a not-yet-ready opencode server cannot disable every overlay for the life of the process. The proxy defs stay spawn-time, so a reused process keeps its defs. Verified live on opencode 1.18.5 (registry has `question`); a build lacking it takes the fallback silently, which the `question proxy version gate` log line makes visible. Tests: `test-proxy-mcp.ts`, `test-cli-args.ts`, `test-subagent-hint.ts`, `test-ask-user-question.ts`. +- Plan-mode approval bridge (`src/plan-mode-question.ts`, absorbed from @CollieIsCute's `8c5b583` with authorship preserved, issue #21) is **opt-in via `planModeQuestion` and off by default**, for the same reason the question proxy is: it delivers through opencode's `question` form, and that form does not render (see the gotcha above), so an enabled bridge turns a working text prompt into a hang. Do not promote it to a default until #36603 merges and the round-trip is re-tested live. What it does when on: `ExitPlanMode` stops being rendered as `**Do you want to proceed with this plan?** (yes/no)` text and instead ends the turn on `tool-calls` with a synthetic `question` tool-call, then the operator's answer is turned back into a `tool_result` **for the original `ExitPlanMode` tool_use id** and sent as the entire next user message. That last part is the whole point of the port: Claude Code only leaves plan mode when it sees that `tool_result`, so a "yes" typed as ordinary prose never actually unlocks it. Invariants: (1) the gate is `isPlanModeQuestionActive` (config + live registry has `question` + not compaction) and it is resolved in the doStream/doGenerate **prologue**, not inside the stream body: the ExitPlanMode branches run in a synchronous line handler and a reused process never reaches the spawn block where the registry snapshot is otherwise taken. (2) Both transports have two ExitPlanMode sites each (partial-event `content_block_stop` and whole-`assistant`-message), so a change to one needs the same change to its twin; all four keep the legacy text path verbatim in the `else`. (3) `clearExitPlanModeQuestions(sk)` runs wherever `deleteClaudeSessionId`/`deleteActiveProcess` do, or a stale pending id outlives its session and the next answer is routed to a dead tool_use. (4) `finishReason` must be `tool-calls` (not the usual unconditional `stop`) when a question call was emitted, or opencode never runs the tool. Offline tests: `test-exit-plan-mode-question.ts`. The approval round-trip itself needs a live opencode session with `permissionMode: "plan"` and is **not verified**; it cannot be while the form is broken. - `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`.

Fields: plugin version, opencode version, `claudeCli` path+version, `cwd` **with the branch that won** (`configured` | `process` | `captured` | `unresolved` — `captured` is the issue-#4 macOS-GUI fingerprint), provider ids, accounts, `proxyTools`, enabled MCP servers, interactive-transport flag, `anthropicApiKeyInEnv`. It is fire-and-forget (`claude --version` is async, 5s timeout, cached) and every field is wrapped so diagnostics can never break provider registration. `describeSpawnCwd` intentionally mirrors `resolveSpawnCwd`'s priority order and a test asserts they never disagree — change both together. The MCP list is the **disk-only** merge (`mergeOpencodeMcp`, split out of `bridgeOpencodeMcp` so diagnostics never writes a scratch config): opencode's runtime status isn't settled at plugin init, so the per-turn overlay is deliberately not applied. The `opencode` field is resolved by `detectOpencodeVersion()`: the plugin runs inside opencode's process, so `process.execPath` **is** the opencode binary and ` --version` is the only reliable source (cached, 5s timeout, guarded on the basename containing "opencode" so a `bun run` from source reports "unknown" instead of Bun's version). It is only spawned when the plugin input and `OPENCODE_VERSION` gave us nothing. Do not "fix" this with an SDK call: re-verified on **1.18.5** that nothing on the plugin surface carries the version (`PluginInput` has no version field, the SDK client's `app` namespace is still only `log` + `agents`, and the server exposes no `/version` route — the route list in `sdk.gen.js` has none). To see the block: `OPENCODE_CLAUDE_CODE_LOG_FILE=1 opencode` then read `~/.local/share/opencode-claude-code/plugin.log` (the plugin logger is silent by default and does **not** write to opencode's own log).

Keep it opt-in until it has Task's mileage; the comment above the constant records why, so do not "tidy" it into the default list. Three invariants: (1) `--disallowedTools` is computed from the **post-filter** proxy list (`enrichedProxy`), never `resolvedProxy` — `filterQuestionProxyByOpencodeSupport` drops the def on opencode builds without a `question` registry entry, and computing from the pre-filter list would disable `AskUserQuestion` while its replacement is absent, leaving the model with no question path at all. (2) `QUESTION_PROXY_HINT` must name the FULL `mcp__opencode_proxy__question`: haiku strips the MCP prefix and calls bare `question`, which opencode renders as `⚙ invalid` (same near-miss family as TaskCreate vs the task proxy). (3) `question` gets a 30-min default in `PROXY_PER_TOOL_DEFAULT_TIMEOUT_MS` because it blocks on a human reading a form; the flat 10-min ceiling rejected calls mid-answer. `fetchLiveToolInfo` does ONE `client.tool.list()` fetch feeding the task overlay, the question gate and the plan-mode gate — do not add a second fetch; `liveToolInfoOnce()` memoizes it per model instance for exactly that reason, and deliberately does **not** memoize an unresolved fetch (`resolved: false`) so a not-yet-ready opencode server cannot disable every overlay for the life of the process. The proxy defs stay spawn-time, so a reused process keeps its defs. Verified live on opencode 1.18.5 (registry has `question`); a build lacking it takes the fallback silently, which the `question proxy version gate` log line makes visible. Tests: `test-proxy-mcp.ts`, `test-cli-args.ts`, `test-subagent-hint.ts`, `test-ask-user-question.ts`. - Plan-mode approval bridge (`src/plan-mode-question.ts`, absorbed from @CollieIsCute's `8c5b583` with authorship preserved, issue #21) is **opt-in via `planModeQuestion` and off by default**, for the same reason the question proxy is: it delivers through opencode's `question` form, and that form does not render (see the gotcha above), so an enabled bridge turns a working text prompt into a hang. Do not promote it to a default until #36603 merges and the round-trip is re-tested live. What it does when on: `ExitPlanMode` stops being rendered as `**Do you want to proceed with this plan?** (yes/no)` text and instead ends the turn on `tool-calls` with a synthetic `question` tool-call, then the operator's answer is turned back into a `tool_result` **for the original `ExitPlanMode` tool_use id** and sent as the entire next user message. That last part is the whole point of the port: Claude Code only leaves plan mode when it sees that `tool_result`, so a "yes" typed as ordinary prose never actually unlocks it. Invariants: (1) the gate is `isPlanModeQuestionActive` (config + live registry has `question` + not compaction) and it is resolved in the doStream/doGenerate **prologue**, not inside the stream body: the ExitPlanMode branches run in a synchronous line handler and a reused process never reaches the spawn block where the registry snapshot is otherwise taken. (2) Both transports have two ExitPlanMode sites each (partial-event `content_block_stop` and whole-`assistant`-message), so a change to one needs the same change to its twin; all four keep the legacy text path verbatim in the `else`. (3) `clearExitPlanModeQuestions(sk)` runs wherever `deleteClaudeSessionId`/`deleteActiveProcess` do, or a stale pending id outlives its session and the next answer is routed to a dead tool_use. (4) `finishReason` must be `tool-calls` (not the usual unconditional `stop`) when a question call was emitted, or opencode never runs the tool. Offline tests: `test-exit-plan-mode-question.ts`. The approval round-trip itself needs a live opencode session with `permissionMode: "plan"` and is **not verified**; it cannot be while the form is broken. +- Compress proxy tool (`src/compression-store.ts` + the `compress` def in `proxy-mcp.ts`, reimplemented from @flupkede's `4ac319f`/`5b4ee5d` on their unmerged `feature/compress-tool` branch, credit theirs). **Opt-in via `proxyTools: [..., "Compress"]`**, deliberately absent from `DEFAULT_PROXY_TOOL_NAMES` — it throws away the model's working context, which is not something to enable behind someone's back. It is the only proxy tool opencode never sees: `createProxyMcpServer`'s third argument is an interceptor map, and an intercepted `tools/call` is answered in-process (no broker entry, no deadline, no permission prompt). Five invariants: + 1. Interceptor results go out through `writeToolCallResult`, the single exit both the broker and interceptor paths share. The fork wrote a JSON-RPC error envelope on interceptor failure, which Claude CLI rejects as a malformed result (same trap as the proxy-mcp gotcha above). + 2. **The summary must survive `deleteClaudeSessionId()`** — the opposite of the plan-mode-question rule, and the fork got this exactly backwards: it cleared the summary there, and the reset path calls it, so the summary was wiped microseconds before the fresh spawn read it and the feature silently did nothing. `clearCompression` is called only from the `!hasPriorConversation` branch (a new opencode conversation), plus a 32-entry cap in the store. Regression test: "summary survives the session reset that the compress call triggers". + 3. The reset runs inside `doStream`'s `start()`, **after** `userMsg` and `includeHistoryContext` were resolved against the still-live session. That ordering is what makes it a real reset: `includeHistoryContext` stays false, so the fresh child gets this turn's message plus the summary in its system prompt and nothing else. Move the reset earlier and `compactConversationHistory` would replay the whole opencode conversation, which is the opposite of compressing. + 4. It is skipped when `hasMatchedPendingResults` — evicting a child whose tool results are arriving this turn would deliver a `tool_result` to a process that never issued the `tool_use`. The mark is not consumed, so it fires on the next turn instead. + 5. `CLAUDE_CLI_COMPRESS_NOTE` replaces `CLAUDE_CLI_CONTEXT_NOTE` only when `compress` is in the **post-overlay** proxy list (`enrichedProxy`), and it spells out the full `mcp__opencode_proxy__compress` for the same reason `QUESTION_PROXY_HINT` does. The default note still tells the model compress does not exist, which stays true for `doGenerate` (no proxy wiring) and the interactive transport (no proxy server). Tests: `test-compress-tool.ts`. The store/interceptor/prompt layers are covered offline; the end-to-end "model calls compress, next turn is fresh" round-trip is **not live-verified**. + - `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`). Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. @@ -96,6 +103,7 @@ These rules supersede the older lifetime-cache and process-cleanup wording in th - Spawn-time cwd resolution (`resolveSpawnCwd`, captured-directory fallback): `test-cwd-resolution.ts`. - AskUserQuestion deny/stop behavior (`denyMessageForTool`, `isAskUserQuestionTool`): `test-ask-user-question.ts`. - Plan-mode approval bridge (`isPlanModeQuestionActive`, `createExitPlanModeQuestionCall`, `consumeExitPlanModeQuestionResult`): `test-exit-plan-mode-question.ts`. +- Compress tool (proxy interceptor path, compression store, compress vs default runtime note): `test-compress-tool.ts`. - Config-path model metadata injection (`configModelsForProvider`): `test-config-models.ts`. - Interactive transport (`decodeUserEnvelope`, `spawnInteractiveProcess` shim shape): `test-claude-session-wrapper.ts`. - Spawn-env API-key stripping (`claudeSpawnEnv` with/without `ignoreAnthropicApiKey`): `test-spawn-env.ts`. @@ -114,16 +122,10 @@ Current state (refreshed 2026-07-26 after the fork/PR sweep): Open work is tracked in issues: #22 (Sonnet 5 standard-pricing bump, merge just before 2026-09-01), #24 (opencode 1.18.5 surface: v2 plugin API, `tool.definition`, compaction hooks — its long-context-cost-tiers item is **closed as not-applicable**, see the pricing gotcha above), #26 (`proxyTools` allowlist-by-omission), #27 (`TaskOutput` shell interpolation). #20 (jknlsn absorption) is complete: timeouts + respawn in v0.10.0, task steering in v0.11.2, question proxy in v0.12.0. #21 (CollieIsCute absorption) is complete: flupkede's four items had already landed independently on 2026-05-18, so compare fork *contents*, not commit counts. -Fork sweep state (2026-08-19): nothing unabsorbed is left on `CollieIsCute/master` or `jknlsn/main`. `flupkede/feature/compress-tool` carried three commits that never reached their master; all three are now **evaluated**: - -- `60a6e9a` (AI-SDK-v4 image parts) is **absorbed** (cherry-picked, authorship preserved). `toImageBlock` accepted `type: "image"` parts but never read `part.image`, where v4 puts the binary, so pasted screenshots were silently dropped with a "file part without data" warning.

The reset waits if the incoming turn is carrying tool results for the running process. + +Without it, the appended system prompt tells the model that `compress` is unavailable and to ignore instructions that ask for it, which is the right answer when nothing implements it. + +Only those seven values are actually proxied; anything else you put in `proxyTools` is ignored. Proxying `Edit` also disables `MultiEdit` — opencode has no batched-edit equivalent, so Claude is forced to fan out into single `Edit` calls that each flow through the permission UI. The `"Question"` proxy is version-gated on opencode's built-in `question` tool: on builds that lack the registry entry the def is silently dropped (a forwarded call would otherwise render as `⚙ invalid`), so add it only on opencode versions that ship the `question` tool. Without `"Task"` in `proxyTools`, Claude's built-in `Agent` tool stays enabled and Claude orchestrates subagents internally with no opencode child-session visibility. To opt out of all proxying, including Task, use an explicit empty list: diff --git a/package.json b/package.json index 9397922..c87fbba 100644 --- a/package.json +++ b/package.json @@ -20,7 +20,7 @@ "build": "tsup", "dev": "tsup --watch", "typecheck": "tsc --noEmit", - "test": "tsx --test test-bridge.ts test-broker.ts test-proxy-mcp.ts test-proxy-task.ts test-auto-continue.ts test-has-new-user-content.ts test-get-claude-user-message.ts test-logger.ts test-cli-args.ts test-session-manager.ts test-compaction-model.ts test-tool-mapping.ts test-cwd-resolution.ts test-todo-ledger.ts test-session-affinity.ts test-config-models.ts test-ask-user-question.ts test-claude-session-wrapper.ts test-spawn-env.ts test-respawn.ts test-startup-diagnostics.ts test-subagent-hint.ts test-exit-plan-mode-question.ts" + "test": "tsx --test test-bridge.ts test-broker.ts test-proxy-mcp.ts test-proxy-task.ts test-auto-continue.ts test-has-new-user-content.ts test-get-claude-user-message.ts test-logger.ts test-cli-args.ts test-session-manager.ts test-compaction-model.ts test-tool-mapping.ts test-cwd-resolution.ts test-todo-ledger.ts test-session-affinity.ts test-config-models.ts test-ask-user-question.ts test-claude-session-wrapper.ts test-spawn-env.ts test-respawn.ts test-startup-diagnostics.ts test-subagent-hint.ts test-exit-plan-mode-question.ts test-compress-tool.ts" }, "dependencies": { "@ai-sdk/provider": "^3.0.8", diff --git a/src/claude-code-language-model.ts b/src/claude-code-language-model.ts index 877e54f..b06da30 100644 --- a/src/claude-code-language-model.ts +++ b/src/claude-code-language-model.ts @@ -45,6 +45,12 @@ import { sessionKey, } from "./session-manager.js" import { spawnInteractiveProcess } from "./claude-session-wrapper.js" +import { + clearCompression, + consumeCompressionRestart, + getCompressionSummary, + storeCompressionSummary, +} from "./compression-store.js" import { log } from "./logger.js" import { detectCliVersion } from "./cli-version.js" import { @@ -58,6 +64,7 @@ import { type ProxyMcpServer, type ProxyToolCall, type ProxyToolDef, + type ProxyToolInterceptor, type ProxyToolResult, } from "./proxy-mcp.js" import { @@ -608,6 +615,22 @@ You are running via the Claude Code CLI (not a direct API call).

What they are waiting on now: -1. **Comment on upstream [anomalyco/opencode#36604](https://github.com/anomalyco/opencode/issues/36604)** (open, fix [PR #36603](https://github.com/anomalyco/opencode/pull/36603) unmerged since 2026-07-13) with our question-form evidence, which is stronger than the report's: (a) the local DB brackets the regression to opencode v1.14.24…v1.15.5 — every `question` tool part is `completed` through 2026-04-25 and every one from 2026-05-18 on is `Tool execution aborted` with `metadata.interrupted: true`; (b) a `--pure` (no-plugin) headless `opencode serve` drives the whole server path green — tool blocks, `question.asked` publishes, `GET /question` lists it, `POST /question/{id}/reply {"answers":[["Alpha"]]}` completes the tool and emits `question.replied` — which isolates the fault to the TUI render step alone. The full write-up already exists as our issue #20 comment; adapt it rather than re-deriving. Re-test our question proxy when #36603 merges. -2. **Ping @jessielaf on issue #4** (cwd for the macOS desktop app). Last three comments are all Khalil's; the 2026-05-16 request to retest v0.4.21 has gone 71 days unanswered. Suggested wording: "v0.4.21+ has been out ~2.5 months, is workspace switching working for you now?" If no reply within a week, close #4 as resolved-pending-feedback (reopens on request) — that also retires roadmap item #5, which is speculative tier-two work nobody has confirmed is needed. +1. **[anomalyco/opencode#36604](https://github.com/anomalyco/opencode/issues/36604)** — our question-form evidence is posted. Two corrections to the older note: **PR #36603 is CLOSED unmerged**, so no fix is landing, and the issue is scoped to *detach + reattach* while our symptom happens with the TUI attached the whole time (the comment says so and offers to file separately if maintainers see it as distinct). Evidence posted: still reproducing on **1.18.18** (2026-08-19); 59 `completed` question parts between 2026-03-31 and 2026-04-25 vs essentially all aborted from 2026-05-18 on, bracketing the regression to v1.14.24…v1.15.5; the single post-boundary `completed` is our own headless `POST /question/{id}/reply` test, which is what isolates the fault to the TUI render step. **Re-test the `question` proxy and `planModeQuestion` when this moves** — both stay off until then. +2. **Issue #4** — @jessielaf pinged for a retest, with the startup-diagnostics `cwd` branch (`captured` is the fingerprint of this bug) as the thing to paste. Stated intent: close as resolved-pending-feedback if there is no reply in about a week, reopening on request. That also retires roadmap item #5.

Fable 5 is included free on plans only through 2026-06-22; after that it needs usage credits.

URL redaction was tested and reverted; the opencode repo URL is not the trigger. Interactive mitigation: live bisection showed this plugin's own CLI/AGENTS/continuation prompt succeeds, while opencode's forwarded system prompt payload can trip the usage gate on constrained subscription accounts. Interactive mode therefore intentionally omits the forwarded opencode system prompt by default. Real account-side fixes remain: enable overage/add extra usage, wait for the 5-hour window reset, switch account/org/plan, or use API-key auth. - `signature_delta` is expected encrypted thinking metadata.

The CLI always emits a `stop_reason`, and `shouldAutoContinueIncompleteTurn` treats any `stop_reason` as authoritative (v0.4.17), so the keyword heuristic below that guard — `looksLikeFinalAnswer` / `looksLikeQuestion` / `looksLikeBlocker` and the whole v0.4.10–v0.4.15 idiom list — is dead code in practice, and `autoContinueIncompleteTurns: "smart"` behaves as `off`. @JWebCoder's PR #15 diagnosed this correctly; it was closed because the remedy (delete the guard) promotes the regex back to the deciding vote on every turn, which is exactly what v0.4.17 removed, and it also carried a `package-lock.json` this repo deliberately does not have. The narrow change worth making, if anyone picks it up: let `max_tokens` fall through to the heuristic, since truncation is the one stop reason that does not mean "finished", while `end_turn`/`stop_sequence` stay authoritative.

A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id.

Rejected requests ended the response but left the connection usable. A peer could declare a large Content-Length, send one byte, take the 401 and hold the socket -- and server.close() does not reap connections that are still sending, so shutdown blocked behind an unauthenticated caller for Node's five-minute request timeout. All five reject paths now go through one helper that sets Connection: close and tears the socket down once the response has flushed. The new regression deliberately never finishes its body. An earlier version of the suite would have masked this, because it destroyed the socket client-side as soon as the response arrived -- exactly the cleanup the server must not depend on. Mutation-checked: with only the Connection: close and teardown removed it fails at 4s instead of passing at 4ms. The 0600 mode assertion is now POSIX-gated. Node implements no owner/group/other mode bits on Windows, where it commonly reads back 0666 and confidentiality rests on the inherited ACL of os.tmpdir() instead, so asserting it there tested nothing and claiming it in the PR would have promised a guarantee this patch does not provide. Comments at the Host and Origin guards were corrected too: the exact-Host check blocks DNS rebinding, NOT a page posting directly to the loopback port, which sends exactly the expected Host. --- src/proxy-mcp.ts | 52 +++++++++++++++++++++++++++++++++------------- test-proxy-mcp.ts | 53 +++++++++++++++++++++++++++++++++++++++++++++-- 2 files changed, 89 insertions(+), 16 deletions(-) diff --git a/src/proxy-mcp.ts b/src/proxy-mcp.ts index cf3f709..a21f253 100644 --- a/src/proxy-mcp.ts +++ b/src/proxy-mcp.ts @@ -616,27 +616,53 @@ export async function createProxyMcpServer( return crypto.timingSafeEqual(candidate, expectedAuth) } + /** + * Reject a request without leaving the connection usable. + * + * Ending the response alone is not enough.

All three error paths in `src/proxy-mcp.ts` now return results with `isError: true`: unknown tool, `result.kind === "error"` (merged into the success path), and the outer `catch` when `requestMethod === "tools/call"`. Non-`tools/call` methods (initialize, tools/list) and unparseable requests still use JSON-RPC errors, which is spec-correct. `requestId`/`requestMethod` are hoisted above the try so the catch can echo them — do not regress to `id: null`. Tests: `test-proxy-mcp.ts`. +- **The proxy MCP endpoint is authenticated.** It executes Bash/Edit/Write through opencode's executor, so before @willmcginnis's PR #28 (0.13.2) any local process could POST to the loopback port and get arbitrary command execution, and a web page could do it blind via a `text/plain` CORS simple request. `createProxyMcpServer` now mints a 256-bit bearer token per server, hands it to Claude in the `headers` block of the generated `--mcp-config` (that file is `0600`, which is now load-bearing), and rejects every request that fails one of four guards, in this order: `Host` must equal the bound `127.0.0.1:` authority (DNS rebinding), `Origin` must be absent, `Content-Type` must be `application/json` (forces a preflight that then fails, closing the simple-request hole), and the bearer token must match under `timingSafeEqual`. All four run **before** `readBody`, so an unauthenticated peer cannot stream a body into memory, and `reject()` sets `Connection: close` and destroys the socket so a slow unauthenticated body cannot hold `server.close()` open. Three consequences to remember: (1) `authToken` must never be logged or put in the URL — the log line in `reject()` deliberately reports only `hasAuthorization`, never values; (2) the Origin and Content-Type guards are **measured properties of the client we spawn**, not spec guarantees, so a future Claude CLI that starts sending an `Origin` would 403 every call — that is exactly why `reject()` logs a reason at NOTICE; (3) anything in-repo that drives the endpoint over HTTP has to authenticate, which is why `test-proxy-mcp.ts` has `authedPost` and `test-compress-tool.ts` threads `srv.authToken`. Live-verified end to end on **Claude Code 2.1.226** (2026-08-20): real CLI, real `--mcp-config`, proxy call received and answered. Do not "simplify" a guard without re-running that check; the unit tests cannot see a client-side header change. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. Tests: `test-proxy-mcp.ts`, `test-broker.ts`. - Reused-process start watchdog. A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. diff --git a/src/proxy-mcp.ts b/src/proxy-mcp.ts index a21f253..91efbd7 100644 --- a/src/proxy-mcp.ts +++ b/src/proxy-mcp.ts @@ -630,7 +630,24 @@ export async function createProxyMcpServer( * destroying the socket on `finish` covers the case where the peer never * finishes its body. */ - function reject(req: IncomingMessage, res: ServerResponse, statusCode: number): void { + function reject( + req: IncomingMessage, + res: ServerResponse, + statusCode: number, + reason: string, + ): void { + // Every guard below is a measured property of the client we spawn, not a + // guarantee about future ones.

Do not "simplify" a guard without re-running that check; the unit tests cannot see a client-side header change. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. Tests: `test-proxy-mcp.ts`, `test-broker.ts`. - Reused-process start watchdog. A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded.

Do not "simplify" a guard without re-running that check; the unit tests cannot see a client-side header change. **Upgrading does not patch a running opencode**: the plugin is loaded once at process start, so every opencode left open from before the upgrade keeps serving an unauthenticated proxy port until it is restarted. Observed on the maintainer's own machine on 2026-08-20, where three sessions from Aug 5 and Aug 18 still answered `POST /mcp` with 200 and 145-byte MCP configs (no `headers` block) while the freshly started one answered 401 with a 272-byte config. That probe (`lsof -nP -iTCP -sTCP:LISTEN | grep opencode`, then an unauthenticated `initialize`, 401 = patched, 200 = stale) is the check to run after any security release, and it is in the README security section for users. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. Tests: `test-proxy-mcp.ts`, `test-broker.ts`. - Reused-process start watchdog. A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. diff --git a/README.md b/README.md index b95e785..e0820e6 100644 --- a/README.md +++ b/README.md @@ -305,6 +305,16 @@ The proxy is a small HTTP MCP server on an ephemeral loopback port, and calling **Upgrade if you are on 0.13.1 or earlier.** Before this, any local process could post to that port and execute commands as you, and a web page you visited could do the same blind, without reading the response.

This prevents empty Thinking rows when the CLI opens a thinking block but streams no text. - opencode's own reasoning features (e.g. v1.17.0 "Added Claude Fable reasoning support", vLLM interleaved `reasoning` field) live in opencode's **native** Anthropic/vLLM runtime, which this plugin deliberately bypasses by routing through the `claude` CLI. There is nothing to "switch to" — the plugin implements reasoning itself (reasoning variants → thinking keyword + `--thinking`/`--thinking-display` flags → `thinking_delta` forwarding), and any model defined with `reasoning: true` (including `claude-fable-5`) inherits the full path automatically. Do not re-investigate adopting opencode's native reasoning; it would mean abandoning the CLI wrapper. - Model display names carry a list-price multiplier as a `(N×)` suffix (`src/models.ts` `defineModel`, via the `multiplier` field): haiku 1×, sonnet 3×, opus 5×, fable 10×, mythos 10×. These are exact ratios of published per-token price vs Haiku (input and output ratios coincide), so Fable/Mythos = 2× Opus. opencode has no native multiplier field, so the suffix is the only way it surfaces in the picker; it's display-only and model resolution still keys off `id`. `test-config-models.ts` asserts the suffixed names — update both if the format changes. +- **Fast mode's `-fast` model ids are OURS, not Anthropic's.** `claude-opus-5-fast` / `claude-opus-4-8-fast` are registry entries this plugin invents; `src/models.ts` `parseModelId` strips the marker before `--model` and turns it into `--settings '{"fastMode":true}'`. Do not "fix" this by passing the id through: Anthropic's real `-fast` names are retired (`claude-opus-4-6-fast` silently falls back to standard, `claude-opus-4-7-fast` hard-errors). There is no `--fast` flag. `--settings` is the only headless opt-in because the CLI's SDK gate reads the **flagSettings** layer specifically (`if (le() && Ui() && !flagSettings.fastMode) return "sdk_opt_in_required"`), so a `fastMode` in the user's own settings.json does nothing for a `--print` run. Only Opus 4.8 / Opus 5 qualify (the CLI matches on the name containing `opus-4-8` / `opus-5`); registering a fast entry for any other model would show a 10× price on a standard-speed turn. Verified live against 2.1.245 on 2026-08-30. `--settings` takes one value, so the interactive wrapper merges `permissions` and `fastMode` into a single payload rather than pushing the flag twice. +- **Fast mode fails soft, so the downgrade must warn, not notice.** An ineligible account returns `fast_mode_state: "off"` with a reason and runs at standard speed with no error, while the picker still advertises 10×. `reportFastModeState` uses `log.warn` deliberately: in `src/logger.ts` only warn/error are alwaysStderr, so a NOTICE would be invisible outside debug mode and defeat the point. Deduped per reason per process, because the blockers are account-level and would otherwise fire on every respawn. Maintainer's own account reports `extra_usage_disabled` (fix: `/usage-credits`), so the on-state path is **unverified in production**: only the opt-in plumbing and the downgrade path have live evidence. - **ACTION DUE 2026-09-01: bump Sonnet 5 to standard pricing.** `claude-sonnet-5` currently ships introductory pricing ($2/M in, $10/M out, `sonnet5Cost`, multiplier 2×) which expires 2026-08-31. From September 1: switch it to `sonnetCost` ($3/$15), multiplier 3×, update the README model table + pricing paragraph and the `test-config-models.ts` assertions (name suffix becomes `(3×)`, cost fields change). The plan is to have an open PR staged with this change and merge it just before Sept 1. - **Costs in `src/models.ts` are dollars per MILLION tokens**, the unit opencode and models.dev use (`~/.cache/opencode/models.json` has `claude-haiku-4-5 -> {"input": 1, ...}`); opencode divides by 1e6 itself. They were per-token until @CNQQC's PR #25 (merged 2026-08-19), which made every reported session cost 1,000,000x too low — do not "restore" the `1e-6` form. `opusCost` is the real Opus 4.5+ standard price ($5/M in, $25/M out — corrected from a stale legacy $15/$75; Opus 5 keeps it). Haiku ($1/$5), Sonnet ($3/$15), and Fable/Mythos ($10/$50) were already correct. If you add a model, set its cost from the published standard (not Fast Mode) pricing so the `(N×)` suffix stays consistent. **Every entry now carries its published `limit`**, audited against the Anthropic models + pricing docs on 2026-07-26 (the placeholder `output: 16_384` is gone; do not reintroduce it). Two classes of drift were corrected: `claude-sonnet-4-5` and `claude-opus-4-5` claimed a **1M context they never had** — the whole 4.5 generation (including Haiku 4.5) is **200k context / 64k output** — while every 4.6-and-later entry is **1M / 128k**. Release dates for the three dated IDs were also wrong and now match the snapshot suffix (haiku `2025-10-01`, sonnet-4-5 `2025-09-29`, opus-4-5 `2025-11-01`). `test-config-models.ts` pins all eleven limits, so a regression fails the suite rather than silently misreporting the context gauge. - **No long-context pricing tier exists — do not add one.** Investigated for issue #24 on 2026-07-26: Anthropic's pricing page has a "Long context pricing" section stating that Claude 4.6 and later include the full 1M window **at standard pricing** ("a 900k-token request is billed at the same per-token rate as a 9k-token request"), with caching and batch discounts unchanged across it. opencode 1.18.5's optional `cost.tiers` / `cost.experimentalOver200K` fields therefore stay unset — populating them would misreport the real price. The premiums that *do* exist are out of scope here: Fast Mode ($10/$50 on Opus 5/4.8, and this plugin never sends `speed: "fast"`), `inference_geo: "us"` (1.1×, not a CLI flag we pass), and partner-cloud regional endpoints (10%, not our path).

From September 1: switch it to `sonnetCost` ($3/$15), multiplier 3×, update the README model table + pricing paragraph and the `test-config-models.ts` assertions (name suffix becomes `(3×)`, cost fields change). The plan is to have an open PR staged with this change and merge it just before Sept 1. +- Sonnet 5 is on **standard pricing** ($3/M in, $15/M out, `sonnetCost`, multiplier 3×) as of 2026-09-01, when its introductory $2/$10 period ended. The `sonnet5Cost` constant is gone; do not reintroduce it, and do not "correct" the 3× suffix back to 2× from an older README or screenshot. - **Costs in `src/models.ts` are dollars per MILLION tokens**, the unit opencode and models.dev use (`~/.cache/opencode/models.json` has `claude-haiku-4-5 -> {"input": 1, ...}`); opencode divides by 1e6 itself. They were per-token until @CNQQC's PR #25 (merged 2026-08-19), which made every reported session cost 1,000,000x too low — do not "restore" the `1e-6` form. `opusCost` is the real Opus 4.5+ standard price ($5/M in, $25/M out — corrected from a stale legacy $15/$75; Opus 5 keeps it). Haiku ($1/$5), Sonnet ($3/$15), and Fable/Mythos ($10/$50) were already correct. If you add a model, set its cost from the published standard (not Fast Mode) pricing so the `(N×)` suffix stays consistent. **Every entry now carries its published `limit`**, audited against the Anthropic models + pricing docs on 2026-07-26 (the placeholder `output: 16_384` is gone; do not reintroduce it). Two classes of drift were corrected: `claude-sonnet-4-5` and `claude-opus-4-5` claimed a **1M context they never had** — the whole 4.5 generation (including Haiku 4.5) is **200k context / 64k output** — while every 4.6-and-later entry is **1M / 128k**. Release dates for the three dated IDs were also wrong and now match the snapshot suffix (haiku `2025-10-01`, sonnet-4-5 `2025-09-29`, opus-4-5 `2025-11-01`). `test-config-models.ts` pins all eleven limits, so a regression fails the suite rather than silently misreporting the context gauge. - **No long-context pricing tier exists — do not add one.** Investigated for issue #24 on 2026-07-26: Anthropic's pricing page has a "Long context pricing" section stating that Claude 4.6 and later include the full 1M window **at standard pricing** ("a 900k-token request is billed at the same per-token rate as a 9k-token request"), with caching and batch discounts unchanged across it. opencode 1.18.5's optional `cost.tiers` / `cost.experimentalOver200K` fields therefore stay unset — populating them would misreport the real price. The premiums that *do* exist are out of scope here: Fast Mode ($10/$50 on Opus 5/4.8, and this plugin never sends `speed: "fast"`), `inference_geo: "us"` (1.1×, not a CLI flag we pass), and partner-cloud regional endpoints (10%, not our path). Re-open only if Anthropic publishes an above-200K rate. A comment above the cost constants in `src/models.ts` records the same finding. - Billing context (researched 2026-06-10, documented in README "Billing change: June 15, 2026"): from 2026-06-15 Anthropic bills `claude -p` / Agent SDK usage (the plugin's default headless `--print` path) against a separate monthly Agent SDK credit on subscription plans (Pro $20 / Max 5x $100 / Max 20x $200), not normal plan limits; API-key auth is unaffected. Same day, `claude-sonnet-4-20250514` / `claude-opus-4-20250514` retire (not registered here, but pass-through overrides could hit them). Fable 5 is included free on plans only through 2026-06-22; after that it needs usage credits. Confirmed failure mechanism: the 400 `Third-party apps now draw from your extra usage...` corresponds to a `rate_limit_event` with `{rateLimitType:"five_hour", overageStatus:"rejected", overageDisabledReason:"org_level_disabled"}` under OAuth subscription auth, so org-level overage/extra usage being disabled can reject requests that do not fit the remaining rolling window. URL redaction was tested and reverted; the opencode repo URL is not the trigger. Interactive mitigation: live bisection showed this plugin's own CLI/AGENTS/continuation prompt succeeds, while opencode's forwarded system prompt payload can trip the usage gate on constrained subscription accounts. Interactive mode therefore intentionally omits the forwarded opencode system prompt by default. Real account-side fixes remain: enable overage/add extra usage, wait for the 5-hour window reset, switch account/org/plan, or use API-key auth. diff --git a/README.md b/README.md index 4dbd04a..e3b18f2 100644 --- a/README.md +++ b/README.md @@ -73,7 +73,7 @@ The plugin auto-registers the following.

Do not pre-nest under `output.options[providerID]`, or the model sees `providerOptions[id][id]`. +- Reasoning effort is a spawn-time env var (`CLAUDE_CODE_EFFORT_LEVEL`, set in `claudeSpawnEnv` and the interactive session's env), not message text. Claude Code 2.1.x only recognises the `ultrathink` keyword, so the old per-level keywords were silently inert. Because the var is fixed per process, effort is part of the session key (`::effort=`); a respawn reads it back from `ActiveProcess.effort`. Compaction spawns never carry it. - **Per-agent model override (`src/agent-models.ts`) swaps the model NAME only, never the provider.** The account lives in the provider (`claude-code-` → `CLAUDE_CONFIG_DIR`) and in the `@` marker on the id, so the override reattaches that marker: `claude-fable-5-1@work` becomes `claude-opus-5@work`. Dropping the marker would silently move the work to the default account. Three guards keep it from surprising anyone, and none of them are optional: `defaultSubagentModel` is **unset by default**, so an upgrade changes no existing behaviour; only agents the plugin discovered (`config.agent` entries, markdown in `agents/`) are eligible, so opencode's built-ins stay out of the path or `explore` quietly becomes an Opus agent; and an unknown model id is refused rather than spawned. The effective model is part of the session key in BOTH `doGenerate` and `doStream`, otherwise an overridden subagent shares a `claude` process with its caller. The plugin defines **no agents of its own** on purpose: a provider plugin injecting opinionated agents (with their own permission blocks) into every user's `@` menu is not its job. - `/compact` must not fall through the no-tools title stub. It is detected via `opencodeAgent === "compaction"`, runs through `doStream`, uses a fresh short-lived Claude CLI process, skips MCP/proxy/tool wiring, and defaults to `claude-haiku-4-5`. - Compaction model precedence is: `CLAUDE_CODE_COMPACTION_MODEL` env var, then `compactionModel` provider option, then default `claude-haiku-4-5`. diff --git a/README.md b/README.md index ead0a52..096b0b3 100644 --- a/README.md +++ b/README.md @@ -666,16 +666,19 @@ The plugin forwards Claude's thinking blocks (`thinking_delta` stream events) to What you see is a **summary** of the model's thinking, not the raw chain-of-thought.

The plugin hands the level to the CLI as `CLAUDE_CODE_EFFORT_LEVEL` at spawn, which Claude Code treats as the session-wide override: it beats the `effortLevel` in that account's `settings.json` and a shell export of the same variable. Effort is fixed for the life of a `claude` process, so it is part of the session key: changing the variant mid-conversation spawns a fresh process with the conversation replayed as context, the same as switching models. + +Earlier versions injected a thinking keyword such as `(ultrathink)` into the user message instead.

Claude Code 2.1.x only recognises the `ultrathink` keyword, so the old per-level keywords were silently inert.

Dropping the marker would silently move the work to the default account. Three guards keep it from surprising anyone, and none of them are optional: `defaultSubagentModel` is **unset by default**, so an upgrade changes no existing behaviour; only agents the plugin discovered (`config.agent` entries, markdown in `agents/`) are eligible, so opencode's built-ins stay out of the path or `explore` quietly becomes an Opus agent; and an unknown model id is refused rather than spawned. The effective model is part of the session key in BOTH `doGenerate` and `doStream`, otherwise an overridden subagent shares a `claude` process with its caller.

Compaction skips request and agent effort overrides, but still inherits a shell-level `CLAUDE_CODE_EFFORT_LEVEL` when set. ### Env-var overrides diff --git a/package.json b/package.json index 5630520..379070b 100644 --- a/package.json +++ b/package.json @@ -20,7 +20,7 @@ "build": "tsup", "dev": "tsup --watch", "typecheck": "tsc --noEmit", - "test": "tsx --test test-bridge.ts test-broker.ts test-proxy-mcp.ts test-proxy-task.ts test-auto-continue.ts test-has-new-user-content.ts test-get-claude-user-message.ts test-logger.ts test-cli-args.ts test-session-manager.ts test-compaction-model.ts test-tool-mapping.ts test-cwd-resolution.ts test-todo-ledger.ts test-session-affinity.ts test-config-models.ts test-ask-user-question.ts test-claude-session-wrapper.ts test-spawn-env.ts test-respawn.ts test-startup-diagnostics.ts test-subagent-hint.ts test-exit-plan-mode-question.ts test-compress-tool.ts test-agent-models.ts" + "test": "tsx --test test-bridge.ts test-broker.ts test-proxy-mcp.ts test-proxy-task.ts test-auto-continue.ts test-has-new-user-content.ts test-get-claude-user-message.ts test-logger.ts test-cli-args.ts test-session-manager.ts test-compaction-model.ts test-tool-mapping.ts test-cwd-resolution.ts test-todo-ledger.ts test-session-affinity.ts test-config-models.ts test-ask-user-question.ts test-claude-session-wrapper.ts test-spawn-env.ts test-respawn.ts test-startup-diagnostics.ts test-subagent-hint.ts test-exit-plan-mode-question.ts test-compress-tool.ts test-agent-models.ts test-side-question.ts test-effort-sessions.ts" }, "dependencies": { "@ai-sdk/provider": "^3.0.8", diff --git a/scripts/live-probe.ts b/scripts/live-probe.ts new file mode 100644 index 0000000..4b851c1 --- /dev/null +++ b/scripts/live-probe.ts @@ -0,0 +1,205 @@ +// Live probe against the real Claude Code CLI.

+54,7 @@ - `WebSearch` with the default `"claude"` routing must NOT be forwarded as a tool-call part. opencode has no `WebSearch` registry entry, and (at least as of opencode v1.17.0) the AI SDK rejects unknown tool names with "Model tried to call unavailable tool" even when `providerExecuted: true` — users saw `⚙ invalid` rows on every CLI-internal web search (fixed after v0.8.0). `mapTool` returns `skip: true` for it, and both tool_use sites in `claude-code-language-model.ts` render the query as a `> **Web search:** …` text line instead (gated by `isWebSearchTool` + `isWebSearchHandledByCli` from `tool-mapping.ts`). Explicit opencode-tool routing (`webSearch: ""`) still forwards with `executed: false`. Tests in `test-tool-mapping.ts`. - `tool-input-delta` parts must only be forwarded for tool calls whose `tool-input-start` was actually emitted. opencode's AI SDK bridge (`packages/opencode/src/session/llm/ai-sdk.ts`) resolves delta/end names via `state.toolNames[event.id] ?? "unknown"`; a delta for an unseen id creates a permanently-pending part with `tool: "unknown"` that the TUI renders as `⚙ unknown`. Skipped tools (ToolSearch, TaskCreate/TaskUpdate, CLI-internal WebSearch, AskUserQuestion, ExitPlanMode, proxy tools) stream `input_json_delta` like any other tool_use, so the streaming site in `claude-code-language-model.ts` gates delta forwarding on a `started` flag set only when the input-start part went out (fixed after v0.8.1). Keep accumulating `inputJson` unconditionally — the skip-path text rendering (AskUserQuestion/ExitPlanMode/WebSearch) depends on it. - Subagent dispatch must be steered at the tool *and* the prompt (absorbed from @jknlsn's `94980a6`, diagnosed on his fork 2026-07-04, re-confirmed live here 2026-07-26). Headless `--print` Claude Code exposes no `Agent`/`Task` dispatch tool of its own (checked through CLI 2.1.211), so the `task` proxy is the only path — but the CLI *does* expose `TaskCreate`, a todo tool, and models resolve opencode's "call the task tool with subagent: X" mention hint straight to it: a todo appears, nothing runs, and the model narrates a successful dispatch. Since Task is proxied by default (v0.10.0) this is reachable without any config. Two spawn-time countermeasures, both required: `overlayTaskProxyDescription` in `proxy-mcp.ts` front-loads opencode's live agent-type list onto the `task` proxy def, and `SUBAGENT_DISPATCH_HINT` goes into the appended system prompt naming `mcp__opencode_proxy__task` as the only dispatch path. **Claude Code truncates long MCP tool descriptions, so position is load-bearing:** jknlsn's original pasted opencode's entire live description (2858 chars) in front of the static def, but opencode puts "Available agent types" at the *end* of it (char 2306), so the only part the model needed was exactly what got cut. Live-verified failure (2026-07-26, haiku): the model asked for `general-purpose`, then `default`, then `code-reviewer` — Claude Code's own agent names — and every dispatch died with `Unknown agent type`, after which it grepped `~/.config/opencode/opencode.json` and answered the question itself. Fix: `extractAgentTypeList` keeps only the list, trims each blurb to 140 chars, drops opencode's generic preamble, and the overlay puts it **first**; total description stays under ~1.4 KB (a test asserts < 1600). Same prompt then dispatched cleanly on the first try (`subagent_type: general`, real child session, `completed`). If you ever grow that description, re-run the live check — a passing unit test will not catch truncation. The hint's ToolSearch line is load-bearing, not padding: harnesses that defer MCP tool schemas (opencode-dcp does) leave `mcp__opencode_proxy__task` invisible while `TaskCreate` stays visible, which is the worst case for this confusion — the maintainer hit exactly that during the v0.10.0 smoke test. `TASK_PROXY_NOTE` must keep describing the real deadline (60 min, `proxyToolTimeoutMs`) and `background` mode; jknlsn's original said 10 minutes, which predated the per-tool timeouts. Only wired into `doStream`'s spawn path — `doGenerate` has no proxy wiring at all, so it deliberately has no hint. Tests: `test-subagent-hint.ts`. +- **`toolCallMap` is keyed by content-block index and MUST be deleted at `content_block_stop`.** Claude CLI restarts block indices at 0 on every assistant message, and one turn routinely holds several (tool_use -> tool_result -> answer, `numTurns: 2`). The entry was never deleted, unlike its neighbours `reasoningIds` and `textBlockIndices`, so message 2's answer-text block at index 0 hit message 1's stale tool_use entry and re-emitted a `tool-call` for an id opencode had already completed. That second part never receives a `tool-result`, so opencode aborts it at stream end with `Tool execution aborted` / `interrupted: true`, and opencode's `task` tool turns that abort into `Subagent failed (task_id: ...)` **even though the child answered correctly and finished with `stop`**. Diagnosed live 2026-09-06 on 0.15.0: three probes, deterministic — a subagent using any provider-executed tool failed, a subagent using no tools returned fine. The plugin log is the tell: two `tool call complete` lines with the same `id`, the second ~2 ms after the final text ends. This was NOT a 0.15.0 regression (aborted parts go back to at least 2026-08-16) and it silently produced the long-standing background noise of `⚙ aborted` rows in the main lane too; it only became a hard failure through the `task` tool. Do not "tidy" the delete away. Test: `test-tool-block-index.ts`, which fails with `got 2` without it. - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry. They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - proxy-mcp `tools/call` responses MUST be MCP results (`{ result: { content, isError } }`), never JSON-RPC error envelopes. Claude CLI validates every `tools/call` response against the MCP result schema and rejects JSON-RPC errors as a "malformed result that failed schema validation" (seen live 2026-07-04 on broker timeouts/orphans — fixed post-0.9.2). All three error paths in `src/proxy-mcp.ts` now return results with `isError: true`: unknown tool, `result.kind === "error"` (merged into the success path), and the outer `catch` when `requestMethod === "tools/call"`. Non-`tools/call` methods (initialize, tools/list) and unparseable requests still use JSON-RPC errors, which is spec-correct. `requestId`/`requestMethod` are hoisted above the try so the catch can echo them — do not regress to `id: null`. Tests: `test-proxy-mcp.ts`. - **The proxy MCP endpoint is authenticated.** It executes Bash/Edit/Write through opencode's executor, so before @willmcginnis's PR #28 (fixed in 0.13.2, disclosed as **GHSA-3mxm-w7gf-3c5x**, High/CVSS 7.5 `AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H`, affecting >= 0.1.3 < 0.13.2; a CVE was requested from GitHub's CNA on 2026-08-20 and was still unassigned at that point — check `gh api /repos/khalilgharbaoui/opencode-claude-code-plugin/security-advisories/GHSA-3mxm-w7gf-3c5x --jq .cve_id` and, once it lands, add it to the README security section and the v0.13.2 release notes) any local process could POST to the loopback port and get arbitrary command execution, and a web page could do it blind via a `text/plain` CORS simple request. `createProxyMcpServer` now mints a 256-bit bearer token per server, hands it to Claude in the `headers` block of the generated `--mcp-config` (that file is `0600`, which is now load-bearing), and rejects every request that fails one of four guards, in this order: `Host` must equal the bound `127.0.0.1:` authority (DNS rebinding), `Origin` must be absent, `Content-Type` must be `application/json` (forces a preflight that then fails, closing the simple-request hole), and the bearer token must match under `timingSafeEqual`. All four run **before** `readBody`, so an unauthenticated peer cannot stream a body into memory, and `reject()` sets `Connection: close` and destroys the socket so a slow unauthenticated body cannot hold `server.close()` open. Three consequences to remember: (1) `authToken` must never be logged or put in the URL — the log line in `reject()` deliberately reports only `hasAuthorization`, never values; (2) the Origin and Content-Type guards are **measured properties of the client we spawn**, not spec guarantees, so a future Claude CLI that starts sending an `Origin` would 403 every call — that is exactly why `reject()` logs a reason at NOTICE; (3) anything in-repo that drives the endpoint over HTTP has to authenticate, which is why `test-proxy-mcp.ts` has `authedPost` and `test-compress-tool.ts` threads `srv.authToken`. Live-verified end to end on **Claude Code 2.1.226** (2026-08-20): real CLI, real `--mcp-config`, proxy call received and answered. Do not "simplify" a guard without re-running that check; the unit tests cannot see a client-side header change. **Upgrading does not patch a running opencode**: the plugin is loaded once at process start, so every opencode left open from before the upgrade keeps serving an unauthenticated proxy port until it is restarted. Observed on the maintainer's own machine on 2026-08-20, where three sessions from Aug 5 and Aug 18 still answered `POST /mcp` with 200 and 145-byte MCP configs (no `headers` block) while the freshly started one answered 401 with a 272-byte config. That probe (`lsof -nP -iTCP -sTCP:LISTEN | grep opencode`, then an unauthenticated `initialize`, 401 = patched, 200 = stale) is the check to run after any security release, and it is in the README security section for users. @@ -107,6 +108,7 @@ These rules supersede the older lifetime-cache and process-cleanup wording in th - Prompt/message conversion or compaction transcript behavior: `test-get-claude-user-message.ts`. - Claude CLI arg construction / version-gated flags: `test-cli-args.ts`.

A real Claude 2.1.258 call held for 390 seconds completed successfully; the previous single-shot response timed out before delivery. Do not claim a specific underlying timer without fresh evidence. `ActiveProcess.pendingProxyCompletions` retains resolved results and shared channel references until continuation settles. Both live and buffered terminal boundaries must consume abandoned completions once, and respawn must preserve the map and original CLI args. Bookkeeping-only stdout must not disarm the start watchdog. Tests: `test-proxy-task.ts`, `test-proxy-mcp.ts`, `test-respawn.ts`. - Native `/btw` (0.15.0): `src/side-question.ts` uses `control_request.request.subtype: "side_question"`, with the answer at `control_response.response.response.response`. The gate is CLI >= 2.1.258 (oldest measured), idle headless process only. Route matching replies through `dispatchSideQuestionResponse` before ordinary stdout buffering. Never send the aside as a user envelope, spawn a different model, or promise a concurrent opencode overlay. Command registration preserves user definitions. History filtering excludes aside exchanges from fresh-process and compaction transcripts. The CLI response has no usage stats. Tests: `test-side-question.ts`, `test-get-claude-user-message.ts`. `scripts/live-probe.ts` is opt-in paid inference, not part of `npm test`. - **The aside question must be stripped of opencode's `` blocks** (`SYSTEM_REMINDER_BLOCK` in `src/side-question.ts`). opencode appends them as *extra text parts* on the same user message, and `parseSideQuestionContent` joins every text part, so without the strip the reminder travels with the aside. Measured live on opencode 1.18.29 (2026-09-06): a 35-character question was sent as 1,599 characters, and a bare `/btw` was never empty, so `SIDE_QUESTION_USAGE` was unreachable and the model answered "I don't see a question in your message" instead. The plan-mode reminder is the worst case (1,523 chars of "READ-ONLY phase / STRICTLY FORBIDDEN"), which is exactly the content most likely to steer an aside. Strip **wherever the block sits**, not by matching a whole part or anchoring at the end: a harness may append trailing metadata after the closing tag (opencode-dcp adds ``), and the first attempt at this fix used `endsWith("")`, passed its unit test, and still did nothing in production for exactly that reason. Only this parse strips reminders; normal turns must keep forwarding them, since they are opencode's instructions to the model. Live-verified after the fix by asking the aside its own word count: 17, matching the question alone. + - **`/btw` is concurrent and lives in a child session (`src/btw-command.ts`, after 0.15.1).** The 0.15.x design put the aside in the main lane, so a `/btw` typed while a turn ran was "Queued" by opencode and then refused by the idle guard, which is the only time anyone wants an aside. Three measured facts drive the replacement, re-check them before changing it: (1) opencode's TUI sends `session.command` immediately, busy or not (`packages/tui/src/component/prompt/index.tsx`, the `void sdk.client.session.command(...)` call), so `command.execute.before` fires at once and only the resulting prompt is queued; (2) a hook that throws makes opencode drop that prompt (no user message is created, the route answers 500, the TUI discards it because its call is fire-and-forget, the server stays healthy; scratch-plugin verified on 1.18.29); (3) Claude Code answers `side_question` while the main loop is blocked (2.1.258, haiku: answered 1.4 s into a 45 s held MCP tool call, main turn then completed normally). So the hook finds the parent's process by opencode session id (`findActiveProcessBySessionId`, fed by the `opencodeSessionID`/`opencodeModel` tags doStream writes on every non-compaction turn), creates or reuses one child session with `parentID`, `promptAsync`s `/btw ` there with the parent's model, toasts, and throws `BtwHandledError`. The child's doStream hits the aside branch, `resolveAsideParent` maps child to parent (in-memory map, `session.get(...).parentID` fallback after a restart), and the request goes to the **parent's** process with `collectSideQuestionHistory` as `history`, then `showBtwAnswerToast`. The idle guard in `requestSideQuestion` is now single-flight only (`pendingProcesses`); `dispatchSideQuestionResponse` runs ahead of the stdout routing in `session-manager.ts`, which is what keeps a streaming turn from ever seeing the control response. The hook only intercepts when `registerSideQuestionCommand` returned true, so a user-defined `btw` command keeps opencode's normal behaviour. Do not route the answer into the parent as a `noReply` message: it renders as a user bubble and shows "Queued" while busy. The old main-lane path is kept for raw `/btw` text from clients that bypass commands. Tests: `test-btw-command.ts` (hook, map, LRU finder, fake-CLI child routing with history), `test-side-question.ts`. - Prompt/message conversion or compaction transcript behavior: `test-get-claude-user-message.ts`. - Claude CLI arg construction / version-gated flags: `test-cli-args.ts`.

A real Claude 2.1.258 call held for 390 seconds completed successfully; the previous single-shot response timed out before delivery. Do not claim a specific underlying timer without fresh evidence. `ActiveProcess.pendingProxyCompletions` retains resolved results and shared channel references until continuation settles. Both live and buffered terminal boundaries must consume abandoned completions once, and respawn must preserve the map and original CLI args. Bookkeeping-only stdout must not disarm the start watchdog. Tests: `test-proxy-task.ts`, `test-proxy-mcp.ts`, `test-respawn.ts`. - Native `/btw` (0.15.0): `src/side-question.ts` uses `control_request.request.subtype: "side_question"`, with the answer at `control_response.response.response.response`. The gate is CLI >= 2.1.258 (oldest measured), idle headless process only. Route matching replies through `dispatchSideQuestionResponse` before ordinary stdout buffering. Never send the aside as a user envelope, spawn a different model, or promise a concurrent opencode overlay. Command registration preserves user definitions. History filtering excludes aside exchanges from fresh-process and compaction transcripts. The CLI response has no usage stats. Tests: `test-side-question.ts`, `test-get-claude-user-message.ts`. `scripts/live-probe.ts` is opt-in paid inference, not part of `npm test`. - **The aside question must be stripped of opencode's `` blocks** (`SYSTEM_REMINDER_BLOCK` in `src/side-question.ts`). opencode appends them as *extra text parts* on the same user message, and `parseSideQuestionContent` joins every text part, so without the strip the reminder travels with the aside. Measured live on opencode 1.18.29 (2026-09-06): a 35-character question was sent as 1,599 characters, and a bare `/btw` was never empty, so `SIDE_QUESTION_USAGE` was unreachable and the model answered "I don't see a question in your message" instead. The plan-mode reminder is the worst case (1,523 chars of "READ-ONLY phase / STRICTLY FORBIDDEN"), which is exactly the content most likely to steer an aside. Strip **wherever the block sits**, not by matching a whole part or anchoring at the end: a harness may append trailing metadata after the closing tag (opencode-dcp adds ``), and the first attempt at this fix used `endsWith("")`, passed its unit test, and still did nothing in production for exactly that reason. Only this parse strips reminders; normal turns must keep forwarding them, since they are opencode's instructions to the model. Live-verified after the fix by asking the aside its own word count: 17, matching the question alone. - - **`/btw` is concurrent and lives in a child session (`src/btw-command.ts`, after 0.15.1).** The 0.15.x design put the aside in the main lane, so a `/btw` typed while a turn ran was "Queued" by opencode and then refused by the idle guard, which is the only time anyone wants an aside. Three measured facts drive the replacement, re-check them before changing it: (1) opencode's TUI sends `session.command` immediately, busy or not (`packages/tui/src/component/prompt/index.tsx`, the `void sdk.client.session.command(...)` call), so `command.execute.before` fires at once and only the resulting prompt is queued; (2) a hook that throws makes opencode drop that prompt (no user message is created, the route answers 500, the TUI discards it because its call is fire-and-forget, the server stays healthy; scratch-plugin verified on 1.18.29); (3) Claude Code answers `side_question` while the main loop is blocked (2.1.258, haiku: answered 1.4 s into a 45 s held MCP tool call, main turn then completed normally). So the hook finds the parent's process by opencode session id (`findActiveProcessBySessionId`, fed by the `opencodeSessionID`/`opencodeModel` tags doStream writes on every non-compaction turn), creates or reuses one child session with `parentID`, `promptAsync`s `/btw ` there with the parent's model, toasts, and throws `BtwHandledError`. The child's doStream hits the aside branch, `resolveAsideParent` maps child to parent (in-memory map, `session.get(...).parentID` fallback after a restart), and the request goes to the **parent's** process with `collectSideQuestionHistory` as `history`, then `showBtwAnswerToast`. The idle guard in `requestSideQuestion` is now single-flight only (`pendingProcesses`); `dispatchSideQuestionResponse` runs ahead of the stdout routing in `session-manager.ts`, which is what keeps a streaming turn from ever seeing the control response. The hook only intercepts when `registerSideQuestionCommand` returned true, so a user-defined `btw` command keeps opencode's normal behaviour. Do not route the answer into the parent as a `noReply` message: it renders as a user bubble and shows "Queued" while busy. The old main-lane path is kept for raw `/btw` text from clients that bypass commands. Tests: `test-btw-command.ts` (hook, map, LRU finder, fake-CLI child routing with history), `test-side-question.ts`. + - **`/btw` is asked early and kept in the conversation (`src/btw-command.ts`, after 0.15.1).** Two designs were rejected live before this one. 0.15.x left the aside in the main lane, so a `/btw` typed mid-turn was "Queued" and then refused by the idle guard. The next attempt answered it in a child session with a toast, which the maintainer rejected on UX: the toast vanished before it could be read and the child session was not where anyone looked. What holds now rests on measured facts, re-check them before changing it: (1) opencode's TUI sends `session.command` immediately, busy or not (`packages/tui/src/component/prompt/index.tsx`), so `command.execute.before` fires at once; the resulting user message is what gets queued. (2) opencode's loop exits only when `lastAssistant.parentID === lastUser.id` (`session/prompt.ts` `runLoop`), so **any** message added to a busy session, `noReply` included, becomes the turn's next step, and that step is also the one carrying the results of the tools opencode just ran. Answering the aside there swallowed the turn's own continuation: measured live, turn 2's "finished" never appeared. (3) Claude Code answers `side_question` while the main loop is blocked (2.1.258: 2.3 s into a 35 s held tool call). So the hook finds the process by opencode session id (`findActiveProcessBySessionId`, fed by the `opencodeSessionID`/`asideTransport` tags doStream writes on every non-compaction turn), sends the `side_question` **immediately**, remembers the promise per session (`rememberSideQuestionAnswer`), toasts the answer when it arrives if the session was busy, and then **holds the command until `client.session.status()` reports the session idle** before returning, so opencode creates the `/btw` message only after the turn is completely over and runs it as a fresh turn. That turn hits the aside branch in `claude-code-language-model.ts`, which takes the remembered answer (`takeSideQuestionAnswer`) or asks the now idle process, and emits it as the assistant reply at 0 tokens; `filterSideQuestionHistory` keeps the pair out of Claude's prompt, and `collectSideQuestionHistory` feeds earlier pairs to follow-ups. Three traps: the remembered answer is matched by **prefix**, not equality, because opencode-dcp appends `` to the message text (an exact match missed live and the turn re-asked into the single-flight guard); busy must come from `session.status`, not the process's line-listener count, because the listener is detached while opencode runs a tool; and holding the route is fine because opencode already keeps the command route open for a queued prompt (34 s observed) and the TUI's call is fire-and-forget. The hook only intercepts when `registerSideQuestionCommand` returned true, so a user-defined `btw` command keeps opencode's normal behaviour. A no-process `/btw` answers with `BTW_NO_SESSION_MESSAGE` as text, not an error. Tests: `test-btw-command.ts` (hook incl. the held return and the give-up timeout, answer store, history fetch, fake-CLI end to end), `test-side-question.ts`. - Prompt/message conversion or compaction transcript behavior: `test-get-claude-user-message.ts`. - Claude CLI arg construction / version-gated flags: `test-cli-args.ts`.

Native `/btw` (0.15.0): `src/side-question.ts` uses `control_request.request.subtype: "side_question"`, with the answer at `control_response.response.response.response`. The gate is CLI >= 2.1.258 (oldest measured), idle headless process only. Route matching replies through `dispatchSideQuestionResponse` before ordinary stdout buffering. Never send the aside as a user envelope, spawn a different model, or promise a concurrent opencode overlay. Command registration preserves user definitions. History filtering excludes aside exchanges from fresh-process and compaction transcripts. The CLI response has no usage stats. Tests: `test-side-question.ts`, `test-get-claude-user-message.ts`. `scripts/live-probe.ts` is opt-in paid inference, not part of `npm test`. - **The aside question must be stripped of opencode's `` blocks** (`SYSTEM_REMINDER_BLOCK` in `src/side-question.ts`). opencode appends them as *extra text parts* on the same user message, and `parseSideQuestionContent` joins every text part, so without the strip the reminder travels with the aside. Measured live on opencode 1.18.29 (2026-09-06): a 35-character question was sent as 1,599 characters, and a bare `/btw` was never empty, so `SIDE_QUESTION_USAGE` was unreachable and the model answered "I don't see a question in your message" instead. The plan-mode reminder is the worst case (1,523 chars of "READ-ONLY phase / STRICTLY FORBIDDEN"), which is exactly the content most likely to steer an aside. Strip **wherever the block sits**, not by matching a whole part or anchoring at the end: a harness may append trailing metadata after the closing tag (opencode-dcp adds ``), and the first attempt at this fix used `endsWith("")`, passed its unit test, and still did nothing in production for exactly that reason. Only this parse strips reminders; normal turns must keep forwarding them, since they are opencode's instructions to the model. Live-verified after the fix by asking the aside its own word count: 17, matching the question alone. - **`/btw` is asked early and kept in the conversation (`src/btw-command.ts`, after 0.15.1).** Two designs were rejected live before this one. 0.15.x left the aside in the main lane, so a `/btw` typed mid-turn was "Queued" and then refused by the idle guard. The next attempt answered it in a child session with a toast, which the maintainer rejected on UX: the toast vanished before it could be read and the child session was not where anyone looked. What holds now rests on measured facts, re-check them before changing it: (1) opencode's TUI sends `session.command` immediately, busy or not (`packages/tui/src/component/prompt/index.tsx`), so `command.execute.before` fires at once; the resulting user message is what gets queued. (2) opencode's loop exits only when `lastAssistant.parentID === lastUser.id` (`session/prompt.ts` `runLoop`), so **any** message added to a busy session, `noReply` included, becomes the turn's next step, and that step is also the one carrying the results of the tools opencode just ran. Answering the aside there swallowed the turn's own continuation: measured live, turn 2's "finished" never appeared. (3) Claude Code answers `side_question` while the main loop is blocked (2.1.258: 2.3 s into a 35 s held tool call). So the hook finds the process by opencode session id (`findActiveProcessBySessionId`, fed by the `opencodeSessionID`/`asideTransport` tags doStream writes on every non-compaction turn), sends the `side_question` **immediately**, remembers the promise per session (`rememberSideQuestionAnswer`), toasts the answer when it arrives if the session was busy, and then **holds the command until `client.session.status()` reports the session idle** before returning, so opencode creates the `/btw` message only after the turn is completely over and runs it as a fresh turn. That turn hits the aside branch in `claude-code-language-model.ts`, which takes the remembered answer (`takeSideQuestionAnswer`) or asks the now idle process, and emits it as the assistant reply at 0 tokens; `filterSideQuestionHistory` keeps the pair out of Claude's prompt, and `collectSideQuestionHistory` feeds earlier pairs to follow-ups. Three traps: the remembered answer is matched by **prefix**, not equality, because opencode-dcp appends `` to the message text (an exact match missed live and the turn re-asked into the single-flight guard); busy must come from `session.status`, not the process's line-listener count, because the listener is detached while opencode runs a tool; and holding the route is fine because opencode already keeps the command route open for a queued prompt (34 s observed) and the TUI's call is fire-and-forget.

Measured live on opencode 1.18.29 (2026-09-06): a 35-character question was sent as 1,599 characters, and a bare `/btw` was never empty, so `SIDE_QUESTION_USAGE` was unreachable and the model answered "I don't see a question in your message" instead. The plan-mode reminder is the worst case (1,523 chars of "READ-ONLY phase / STRICTLY FORBIDDEN"), which is exactly the content most likely to steer an aside. Strip **wherever the block sits**, not by matching a whole part or anchoring at the end: a harness may append trailing metadata after the closing tag (opencode-dcp adds ``), and the first attempt at this fix used `endsWith("")`, passed its unit test, and still did nothing in production for exactly that reason. Only this parse strips reminders; normal turns must keep forwarding them, since they are opencode's instructions to the model. Live-verified after the fix by asking the aside its own word count: 17, matching the question alone. - **`/btw` is asked early and kept in the conversation (`src/btw-command.ts`, after 0.15.1).** Two designs were rejected live before this one. 0.15.x left the aside in the main lane, so a `/btw` typed mid-turn was "Queued" and then refused by the idle guard. The next attempt answered it in a child session with a toast, which the maintainer rejected on UX: the toast vanished before it could be read and the child session was not where anyone looked. What holds now rests on measured facts, re-check them before changing it: (1) opencode's TUI sends `session.command` immediately, busy or not (`packages/tui/src/component/prompt/index.tsx`), so `command.execute.before` fires at once; the resulting user message is what gets queued. (2) opencode's loop exits only when `lastAssistant.parentID === lastUser.id` (`session/prompt.ts` `runLoop`), so **any** message added to a busy session, `noReply` included, becomes the turn's next step, and that step is also the one carrying the results of the tools opencode just ran. Answering the aside there swallowed the turn's own continuation: measured live, turn 2's "finished" never appeared. (3) Claude Code answers `side_question` while the main loop is blocked (2.1.258: 2.3 s into a 35 s held tool call). So the hook finds the process by opencode session id (`findActiveProcessBySessionId`, fed by the `opencodeSessionID`/`asideTransport` tags doStream writes on every non-compaction turn), sends the `side_question` **immediately**, remembers the promise per session (`rememberSideQuestionAnswer`), toasts the answer when it arrives if the session was busy, and then **holds the command until `client.session.status()` reports the session idle** before returning, so opencode creates the `/btw` message only after the turn is completely over and runs it as a fresh turn. That turn hits the aside branch in `claude-code-language-model.ts`, which takes the remembered answer (`takeSideQuestionAnswer`) or asks the now idle process, and emits it as the assistant reply at 0 tokens; `filterSideQuestionHistory` keeps the pair out of Claude's prompt, and `collectSideQuestionHistory` feeds earlier pairs to follow-ups. Three traps: the remembered answer is matched by **prefix**, not equality, because opencode-dcp appends `` to the message text (an exact match missed live and the turn re-asked into the single-flight guard); busy must come from `session.status`, not the process's line-listener count, because the listener is detached while opencode runs a tool; and holding the route is fine because opencode already keeps the command route open for a queued prompt (34 s observed) and the TUI's call is fire-and-forget. The hook only intercepts when `registerSideQuestionCommand` returned true, so a user-defined `btw` command keeps opencode's normal behaviour. A no-process `/btw` answers with `BTW_NO_SESSION_MESSAGE` as text, not an error. Tests: `test-btw-command.ts` (hook incl. the held return and the give-up timeout, answer store, history fetch, fake-CLI end to end), `test-side-question.ts`. - **Both lookups the hook makes are racy the instant `/btw` is typed, and losing either race puts the "Queued" bubble straight back.** Reported live 2026-09-06 ("if i do the /btw too soo it still gets queued") and confirmed in `plugin.log`: `btw: no live claude process for session` at 14:04:06, then the same question at 14:04:28 found a process and was answered concurrently. Cause: doStream tags the process (`opencodeSessionID`/`asideTransport`) only where it attaches its line listener, which is **after the whole spawn path**, so on a conversation's first turn there is a multi-second window with nothing to ask; the hook fell through, and the message it let past is exactly what opencode queues. The same shape applies to `session.status`, where a session that opencode has not registered yet is **absent from the map and therefore reads as idle**, so a single early read says "not busy" and the hold is skipped. So `waitForAsideProcess` polls for the process while the session is busy (giving up after `SPAWN_WAIT_MAX_MS`, 30 s, because the running turn may belong to another provider and then no process is ever coming), and `settleSessionBusy` keeps re-reading status for `BUSY_SETTLE_MS` (1.5 s) before it will conclude idle. Two ordering rules hold this together: the settle runs **concurrently** with the request, never before it, or an idle `/btw` would wait out the settle window before being asked at all; and `answer.catch(() => undefined)` goes on immediately, because the settle spans timer ticks and a fast failure (dead process, interactive transport) would otherwise surface as an unhandled rejection in opencode's own process before the real handlers are attached. The suite caught that second one, so do not remove it as dead code. + - **The answer is written into the running turn's own reply, and only falls back to the toast plus a held message.** The toast was the delivery while a turn ran, and the maintainer rejected it twice for the same reason ("the notification is too short and is gone right away", then "can you also add it printed to the main thread"): a toast expires, and the held `/btw` pair could not land until the turn was over. So `doStream` registers an `AsideSink` per conversation (`registerAsideSink(affinity, ...)`, unregistered in `cleanupTurn`) that enqueues one finished text block into the live stream, and `deliverAsideInline` uses it; on success the hook throws `BtwHandledError` so opencode never creates the `/btw` message at all, since the answer is already in the transcript. Four things this rests on: (1) the sink is keyed by `affinity`, which **is** the opencode session id, the same key `takeSideQuestionAnswer` uses. (2) `registerAsideSink` returns an unregister that only deletes its own sink, because a turn's cleanup runs after the next turn has already registered. (3) A turn is a **run of streams**, not one: every proxy tool call ends the stream (`finishWithPendingProxyCalls`) and opencode opens the next one with the result, so an answer arriving in that gap has nothing to write to. `deliverAsideInline` therefore retries for `INLINE_WAIT_MAX_MS` (20 s) while the session stays busy and only then falls back to the toast plus the held message, which is still the whole point of keeping that path. (4) The block is its own text part led by `INLINE_ASIDE_MARKER` (`> **btw:**`), which is what lets `filterSideQuestionHistory` strip it exactly when a transcript is rebuilt: an aside was never Claude's output and was never in its context. Do not merge it into the model's own text block, and do not match the marker mid-part; the strip is part-level for a reason. Live-verified 2026-09-06 on Claude 2.1.258 + opencode 1.18.29: `/btw` typed 15 s into a 35 s webfetch, block written 1.4 s later inside that turn's assistant message, no `/btw` message in the transcript, turn still delivered its own "finished".

**`/btw` is asked early and kept in the conversation (`src/btw-command.ts`, after 0.15.1).** Two designs were rejected live before this one. 0.15.x left the aside in the main lane, so a `/btw` typed mid-turn was "Queued" and then refused by the idle guard. The next attempt answered it in a child session with a toast, which the maintainer rejected on UX: the toast vanished before it could be read and the child session was not where anyone looked. What holds now rests on measured facts, re-check them before changing it: (1) opencode's TUI sends `session.command` immediately, busy or not (`packages/tui/src/component/prompt/index.tsx`), so `command.execute.before` fires at once; the resulting user message is what gets queued. (2) opencode's loop exits only when `lastAssistant.parentID === lastUser.id` (`session/prompt.ts` `runLoop`), so **any** message added to a busy session, `noReply` included, becomes the turn's next step, and that step is also the one carrying the results of the tools opencode just ran. Answering the aside there swallowed the turn's own continuation: measured live, turn 2's "finished" never appeared. (3) Claude Code answers `side_question` while the main loop is blocked (2.1.258: 2.3 s into a 35 s held tool call). So the hook finds the process by opencode session id (`findActiveProcessBySessionId`, fed by the `opencodeSessionID`/`asideTransport` tags doStream writes on every non-compaction turn), sends the `side_question` **immediately**, remembers the promise per session (`rememberSideQuestionAnswer`), toasts the answer when it arrives if the session was busy, and then **holds the command until `client.session.status()` reports the session idle** before returning, so opencode creates the `/btw` message only after the turn is completely over and runs it as a fresh turn. That turn hits the aside branch in `claude-code-language-model.ts`, which takes the remembered answer (`takeSideQuestionAnswer`) or asks the now idle process, and emits it as the assistant reply at 0 tokens; `filterSideQuestionHistory` keeps the pair out of Claude's prompt, and `collectSideQuestionHistory` feeds earlier pairs to follow-ups. Three traps: the remembered answer is matched by **prefix**, not equality, because opencode-dcp appends `` to the message text (an exact match missed live and the turn re-asked into the single-flight guard); busy must come from `session.status`, not the process's line-listener count, because the listener is detached while opencode runs a tool; and holding the route is fine because opencode already keeps the command route open for a queued prompt (34 s observed) and the TUI's call is fire-and-forget. The hook only intercepts when `registerSideQuestionCommand` returned true, so a user-defined `btw` command keeps opencode's normal behaviour. A no-process `/btw` answers with `BTW_NO_SESSION_MESSAGE` as text, not an error. Tests: `test-btw-command.ts` (hook incl. the held return and the give-up timeout, answer store, history fetch, fake-CLI end to end), `test-side-question.ts`. - **Both lookups the hook makes are racy the instant `/btw` is typed, and losing either race puts the "Queued" bubble straight back.** Reported live 2026-09-06 ("if i do the /btw too soo it still gets queued") and confirmed in `plugin.log`: `btw: no live claude process for session` at 14:04:06, then the same question at 14:04:28 found a process and was answered concurrently. Cause: doStream tags the process (`opencodeSessionID`/`asideTransport`) only where it attaches its line listener, which is **after the whole spawn path**, so on a conversation's first turn there is a multi-second window with nothing to ask; the hook fell through, and the message it let past is exactly what opencode queues. The same shape applies to `session.status`, where a session that opencode has not registered yet is **absent from the map and therefore reads as idle**, so a single early read says "not busy" and the hold is skipped. So `waitForAsideProcess` polls for the process while the session is busy (giving up after `SPAWN_WAIT_MAX_MS`, 30 s, because the running turn may belong to another provider and then no process is ever coming), and `settleSessionBusy` keeps re-reading status for `BUSY_SETTLE_MS` (1.5 s) before it will conclude idle. Two ordering rules hold this together: the settle runs **concurrently** with the request, never before it, or an idle `/btw` would wait out the settle window before being asked at all; and `answer.catch(() => undefined)` goes on immediately, because the settle spans timer ticks and a fast failure (dead process, interactive transport) would otherwise surface as an unhandled rejection in opencode's own process before the real handlers are attached. The suite caught that second one, so do not remove it as dead code. - **The answer is written into the running turn's own reply, and only falls back to the toast plus a held message.** The toast was the delivery while a turn ran, and the maintainer rejected it twice for the same reason ("the notification is too short and is gone right away", then "can you also add it printed to the main thread"): a toast expires, and the held `/btw` pair could not land until the turn was over. So `doStream` registers an `AsideSink` per conversation (`registerAsideSink(affinity, ...)`, unregistered in `cleanupTurn`) that enqueues one finished text block into the live stream, and `deliverAsideInline` uses it; on success the hook throws `BtwHandledError` so opencode never creates the `/btw` message at all, since the answer is already in the transcript. Four things this rests on: (1) the sink is keyed by `affinity`, which **is** the opencode session id, the same key `takeSideQuestionAnswer` uses. (2) `registerAsideSink` returns an unregister that only deletes its own sink, because a turn's cleanup runs after the next turn has already registered. (3) A turn is a **run of streams**, not one: every proxy tool call ends the stream (`finishWithPendingProxyCalls`) and opencode opens the next one with the result, so an answer arriving in that gap has nothing to write to. `deliverAsideInline` therefore retries for `INLINE_WAIT_MAX_MS` (20 s) while the session stays busy and only then falls back to the toast plus the held message, which is still the whole point of keeping that path.

Measured live on opencode 1.18.29 (2026-09-06): a 35-character question was sent as 1,599 characters, and a bare `/btw` was never empty, so `SIDE_QUESTION_USAGE` was unreachable and the model answered "I don't see a question in your message" instead. The plan-mode reminder is the worst case (1,523 chars of "READ-ONLY phase / STRICTLY FORBIDDEN"), which is exactly the content most likely to steer an aside. Strip **wherever the block sits**, not by matching a whole part or anchoring at the end: a harness may append trailing metadata after the closing tag (opencode-dcp adds ``), and the first attempt at this fix used `endsWith("")`, passed its unit test, and still did nothing in production for exactly that reason. Only this parse strips reminders; normal turns must keep forwarding them, since they are opencode's instructions to the model. Live-verified after the fix by asking the aside its own word count: 17, matching the question alone. - **`/btw` is asked early and kept in the conversation (`src/btw-command.ts`, after 0.15.1).** Two designs were rejected live before this one. 0.15.x left the aside in the main lane, so a `/btw` typed mid-turn was "Queued" and then refused by the idle guard. The next attempt answered it in a child session with a toast, which the maintainer rejected on UX: the toast vanished before it could be read and the child session was not where anyone looked. What holds now rests on measured facts, re-check them before changing it: (1) opencode's TUI sends `session.command` immediately, busy or not (`packages/tui/src/component/prompt/index.tsx`), so `command.execute.before` fires at once; the resulting user message is what gets queued. (2) opencode's loop exits only when `lastAssistant.parentID === lastUser.id` (`session/prompt.ts` `runLoop`), so **any** message added to a busy session, `noReply` included, becomes the turn's next step, and that step is also the one carrying the results of the tools opencode just ran. Answering the aside there swallowed the turn's own continuation: measured live, turn 2's "finished" never appeared. (3) Claude Code answers `side_question` while the main loop is blocked (2.1.258: 2.3 s into a 35 s held tool call). So the hook finds the process by opencode session id (`findActiveProcessBySessionId`, fed by the `opencodeSessionID`/`asideTransport` tags doStream writes on every non-compaction turn), sends the `side_question` **immediately**, remembers the promise per session (`rememberSideQuestionAnswer`), toasts the answer when it arrives if the session was busy, and then **holds the command until `client.session.status()` reports the session idle** before returning, so opencode creates the `/btw` message only after the turn is completely over and runs it as a fresh turn. That turn hits the aside branch in `claude-code-language-model.ts`, which takes the remembered answer (`takeSideQuestionAnswer`) or asks the now idle process, and emits it as the assistant reply at 0 tokens; `filterSideQuestionHistory` keeps the pair out of Claude's prompt, and `collectSideQuestionHistory` feeds earlier pairs to follow-ups. Three traps: the remembered answer is matched by **prefix**, not equality, because opencode-dcp appends `` to the message text (an exact match missed live and the turn re-asked into the single-flight guard); busy must come from `session.status`, not the process's line-listener count, because the listener is detached while opencode runs a tool; and holding the route is fine because opencode already keeps the command route open for a queued prompt (34 s observed) and the TUI's call is fire-and-forget. The hook only intercepts when `registerSideQuestionCommand` returned true, so a user-defined `btw` command keeps opencode's normal behaviour. A no-process `/btw` answers with `BTW_NO_SESSION_MESSAGE` as text, not an error. Tests: `test-btw-command.ts` (hook incl. the held return and the give-up timeout, answer store, history fetch, fake-CLI end to end), `test-side-question.ts`. - **Both lookups the hook makes are racy the instant `/btw` is typed, and losing either race puts the "Queued" bubble straight back.** Reported live 2026-09-06 ("if i do the /btw too soo it still gets queued") and confirmed in `plugin.log`: `btw: no live claude process for session` at 14:04:06, then the same question at 14:04:28 found a process and was answered concurrently. Cause: doStream tags the process (`opencodeSessionID`/`asideTransport`) only where it attaches its line listener, which is **after the whole spawn path**, so on a conversation's first turn there is a multi-second window with nothing to ask; the hook fell through, and the message it let past is exactly what opencode queues. The same shape applies to `session.status`, where a session that opencode has not registered yet is **absent from the map and therefore reads as idle**, so a single early read says "not busy" and the hold is skipped. So `waitForAsideProcess` polls for the process while the session is busy (giving up after `SPAWN_WAIT_MAX_MS`, 30 s, because the running turn may belong to another provider and then no process is ever coming), and `settleSessionBusy` keeps re-reading status for `BUSY_SETTLE_MS` (1.5 s) before it will conclude idle. Two ordering rules hold this together: the settle runs **concurrently** with the request, never before it, or an idle `/btw` would wait out the settle window before being asked at all; and `answer.catch(() => undefined)` goes on immediately, because the settle spans timer ticks and a fast failure (dead process, interactive transport) would otherwise surface as an unhandled rejection in opencode's own process before the real handlers are attached. The suite caught that second one, so do not remove it as dead code. - - **The answer is written into the running turn's own reply, and only falls back to the toast plus a held message.** The toast was the delivery while a turn ran, and the maintainer rejected it twice for the same reason ("the notification is too short and is gone right away", then "can you also add it printed to the main thread"): a toast expires, and the held `/btw` pair could not land until the turn was over. So `doStream` registers an `AsideSink` per conversation (`registerAsideSink(affinity, ...)`, unregistered in `cleanupTurn`) that enqueues one finished text block into the live stream, and `deliverAsideInline` uses it; on success the hook throws `BtwHandledError` so opencode never creates the `/btw` message at all, since the answer is already in the transcript. Four things this rests on: (1) the sink is keyed by `affinity`, which **is** the opencode session id, the same key `takeSideQuestionAnswer` uses. (2) `registerAsideSink` returns an unregister that only deletes its own sink, because a turn's cleanup runs after the next turn has already registered. (3) A turn is a **run of streams**, not one: every proxy tool call ends the stream (`finishWithPendingProxyCalls`) and opencode opens the next one with the result, so an answer arriving in that gap has nothing to write to. `deliverAsideInline` therefore retries for `INLINE_WAIT_MAX_MS` (20 s) while the session stays busy and only then falls back to the toast plus the held message, which is still the whole point of keeping that path.

Read `@opentui/core`'s `src/renderables/Markdown.ts` before touching this (`npm pack @opentui/core`, the sourcemap carries the TS): a blockquote **does** get a real left border (`createBlockquoteRenderable` → `BoxRenderable` with `border: ["left"]`, `paddingLeft: 1`), but `getBlockquoteBorderColor()` reads the **`conceal`** scope, falling back to `default`, while `theme.markdownBlockQuote` / `markup.quote` colours only the quoted **text**. So the one key a theme could plausibly change is the one that does not paint the bar, there is no per-block override, and a custom theme is the operator's config anyway (opencode resolves `theme.theme` as-is, with no merge over a base, so it means copying a whole theme). The session route also runs text through `strip-ansi`, so escape codes are not a way in. `barEveryLine` therefore prefixes **every** line, blank ones as a bare `▌`, so the bar runs the full height. Two facts hold the rendering together, both from the same file: OpenTUI renders a paragraph from `token.raw` **verbatim**, so line breaks survive and nothing reflows; and blockquote content goes through `createMarkdownCodeRenderable(token.text, …)` rather than being re-parsed, so the old shape never rendered nested markdown either and dropping it costs nothing. `INLINE_ASIDE_MARKER` must stay the leading characters after `trimStart()` or `filterSideQuestionHistory` stops stripping the block; `LEGACY_INLINE_ASIDE_MARKERS` keeps the old `> **btw:**` blocks strippable in conversations that predate the change, and a test covers it. - Prompt/message conversion or compaction transcript behavior: `test-get-claude-user-message.ts`. - Claude CLI arg construction / version-gated flags: `test-cli-args.ts`.

Cause: doStream tags the process (`opencodeSessionID`/`asideTransport`) only where it attaches its line listener, which is **after the whole spawn path**, so on a conversation's first turn there is a multi-second window with nothing to ask; the hook fell through, and the message it let past is exactly what opencode queues. The same shape applies to `session.status`, where a session that opencode has not registered yet is **absent from the map and therefore reads as idle**, so a single early read says "not busy" and the hold is skipped. So `waitForAsideProcess` polls for the process while the session is busy (giving up after `SPAWN_WAIT_MAX_MS`, 30 s, because the running turn may belong to another provider and then no process is ever coming), and `settleSessionBusy` keeps re-reading status for `BUSY_SETTLE_MS` (1.5 s) before it will conclude idle. Two ordering rules hold this together: the settle runs **concurrently** with the request, never before it, or an idle `/btw` would wait out the settle window before being asked at all; and `answer.catch(() => undefined)` goes on immediately, because the settle spans timer ticks and a fast failure (dead process, interactive transport) would otherwise surface as an unhandled rejection in opencode's own process before the real handlers are attached. The suite caught that second one, so do not remove it as dead code. - **The answer is written into the running turn's own reply, and only falls back to the toast plus a held message.** The toast was the delivery while a turn ran, and the maintainer rejected it twice for the same reason ("the notification is too short and is gone right away", then "can you also add it printed to the main thread"): a toast expires, and the held `/btw` pair could not land until the turn was over. So `doStream` registers an `AsideSink` per conversation (`registerAsideSink(affinity, ...)`, unregistered in `cleanupTurn`) that enqueues one finished text block into the live stream, and `deliverAsideInline` uses it; on success the hook throws `BtwHandledError` so opencode never creates the `/btw` message at all, since the answer is already in the transcript. Four things this rests on: (1) the sink is keyed by `affinity`, which **is** the opencode session id, the same key `takeSideQuestionAnswer` uses. (2) `registerAsideSink` returns an unregister that only deletes its own sink, because a turn's cleanup runs after the next turn has already registered. (3) A turn is a **run of streams**, not one: every proxy tool call ends the stream (`finishWithPendingProxyCalls`) and opencode opens the next one with the result, so an answer arriving in that gap has nothing to write to. `deliverAsideInline` therefore retries for `INLINE_WAIT_MAX_MS` (20 s) while the session stays busy and only then falls back to the toast plus the held message, which is still the whole point of keeping that path. (4) The block is its own text part led by `INLINE_ASIDE_MARKER` (`▌ **btw:**`), which is what lets `filterSideQuestionHistory` strip it exactly when a transcript is rebuilt: an aside was never Claude's output and was never in its context. Do not merge it into the model's own text block, and do not match the marker mid-part; the strip is part-level for a reason. Live-verified 2026-09-06 on Claude 2.1.258 + opencode 1.18.29: `/btw` typed 15 s into a 35 s webfetch, block written 1.4 s later inside that turn's assistant message, no `/btw` message in the transcript, turn still delivered its own "finished". Note the command route answers **HTTP 500** on the drop, as it does for every `BtwHandledError`; the TUI's `session.command` call is fire-and-forget and swallows it. Tests: `test-btw-command.ts` (sink ownership, marker strip, and a fake-CLI turn held open by the `SLOW` keyword that the aside is written into). - **The aside's left bar is a literal `▌` the plugin emits, NOT a markdown blockquote.** Asked for "a subtle green border around the full response", and the blockquote answer shipped first and was wrong; it was replaced after the maintainer reported "the theme is picked but nothing green shows up", which is exactly what the source predicts. Read `@opentui/core`'s `src/renderables/Markdown.ts` before touching this (`npm pack @opentui/core`, the sourcemap carries the TS): a blockquote **does** get a real left border (`createBlockquoteRenderable` → `BoxRenderable` with `border: ["left"]`, `paddingLeft: 1`), but `getBlockquoteBorderColor()` reads the **`conceal`** scope, falling back to `default`, while `theme.markdownBlockQuote` / `markup.quote` colours only the quoted **text**. So the one key a theme could plausibly change is the one that does not paint the bar, there is no per-block override, and a custom theme is the operator's config anyway (opencode resolves `theme.theme` as-is, with no merge over a base, so it means copying a whole theme). The session route also runs text through `strip-ansi`, so escape codes are not a way in. `barEveryLine` therefore prefixes **every** line, blank ones as a bare `▌`, so the bar runs the full height. Two facts hold the rendering together, both from the same file: OpenTUI renders a paragraph from `token.raw` **verbatim**, so line breaks survive and nothing reflows; and blockquote content goes through `createMarkdownCodeRenderable(token.text, …)` rather than being re-parsed, so the old shape never rendered nested markdown either and dropping it costs nothing. `INLINE_ASIDE_MARKER` must stay the leading characters after `trimStart()` or `filterSideQuestionHistory` stops stripping the block; `LEGACY_INLINE_ASIDE_MARKERS` keeps the old `> **btw:**` blocks strippable in conversations that predate the change, and a test covers it. + - **No toast ever carries the answer** ("so we can get rid of the notification now?", once the inline block worked). Every path that produces an answer now puts it in the conversation, inline or as the held pair, so announcing it as well was duplicate delivery of the *worse* copy: a toast expires, which is the complaint that started this whole redesign. Removed with it: `answerToastMessage` / `answerToastDuration` and the `ANSWER_TOAST_*` sizing constants, `BTW_BUSY_TOAST_MESSAGE` (the "answering alongside the turn" notice, which the inline block obsoletes) and `BTW_IN_FLIGHT_TOAST_MESSAGE` (a second `/btw` still gets asked when the turn ends, so its answer lands too). The **two** that stay are exactly the paths where nothing reaches the conversation because the message is dropped: a bare `/btw` (`SIDE_QUESTION_USAGE`) and `BTW_TURN_TOO_LONG_MESSAGE` after the 30 minute hold gives up. That is the rule to apply to any new toast here: if the conversation gets the content, do not also toast it. `showToast` itself stays, and so does the `tui.showToast` receiver-binding care in it (a detached `const show = client.tui.showToast` throws, since the SDK method reads `this._client`). - Prompt/message conversion or compaction transcript behavior: `test-get-claude-user-message.ts`. - Claude CLI arg construction / version-gated flags: `test-cli-args.ts`.

(3) A turn is a **run of streams**, not one: every proxy tool call ends the stream (`finishWithPendingProxyCalls`) and opencode opens the next one with the result, so an answer arriving in that gap has nothing to write to. `deliverAsideInline` therefore retries for `INLINE_WAIT_MAX_MS` (20 s) while the session stays busy and only then falls back to the toast plus the held message, which is still the whole point of keeping that path. (4) The block is its own text part led by `INLINE_ASIDE_MARKER` (`▌ **btw:**`), which is what lets `filterSideQuestionHistory` strip it exactly when a transcript is rebuilt: an aside was never Claude's output and was never in its context. Do not merge it into the model's own text block, and do not match the marker mid-part; the strip is part-level for a reason. Live-verified 2026-09-06 on Claude 2.1.258 + opencode 1.18.29: `/btw` typed 15 s into a 35 s webfetch, block written 1.4 s later inside that turn's assistant message, no `/btw` message in the transcript, turn still delivered its own "finished". Note the command route answers **HTTP 500** on the drop, as it does for every `BtwHandledError`; the TUI's `session.command` call is fire-and-forget and swallows it. Tests: `test-btw-command.ts` (sink ownership, marker strip, and a fake-CLI turn held open by the `SLOW` keyword that the aside is written into). - **The aside's left bar is a literal `▌` the plugin emits, NOT a markdown blockquote.** Asked for "a subtle green border around the full response", and the blockquote answer shipped first and was wrong; it was replaced after the maintainer reported "the theme is picked but nothing green shows up", which is exactly what the source predicts. Read `@opentui/core`'s `src/renderables/Markdown.ts` before touching this (`npm pack @opentui/core`, the sourcemap carries the TS): a blockquote **does** get a real left border (`createBlockquoteRenderable` → `BoxRenderable` with `border: ["left"]`, `paddingLeft: 1`), but `getBlockquoteBorderColor()` reads the **`conceal`** scope, falling back to `default`, while `theme.markdownBlockQuote` / `markup.quote` colours only the quoted **text**. So the one key a theme could plausibly change is the one that does not paint the bar, there is no per-block override, and a custom theme is the operator's config anyway (opencode resolves `theme.theme` as-is, with no merge over a base, so it means copying a whole theme). The session route also runs text through `strip-ansi`, so escape codes are not a way in. `barEveryLine` therefore prefixes **every** line, blank ones as a bare `▌`, so the bar runs the full height. Two facts hold the rendering together, both from the same file: OpenTUI renders a paragraph from `token.raw` **verbatim**, so line breaks survive and nothing reflows; and blockquote content goes through `createMarkdownCodeRenderable(token.text, …)` rather than being re-parsed, so the old shape never rendered nested markdown either and dropping it costs nothing. `INLINE_ASIDE_MARKER` must stay the leading characters after `trimStart()` or `filterSideQuestionHistory` stops stripping the block; `LEGACY_INLINE_ASIDE_MARKERS` keeps the old `> **btw:**` blocks strippable in conversations that predate the change, and a test covers it. - **No toast ever carries the answer** ("so we can get rid of the notification now?", once the inline block worked). Every path that produces an answer now puts it in the conversation, inline or as the held pair, so announcing it as well was duplicate delivery of the *worse* copy: a toast expires, which is the complaint that started this whole redesign. Removed with it: `answerToastMessage` / `answerToastDuration` and the `ANSWER_TOAST_*` sizing constants, `BTW_BUSY_TOAST_MESSAGE` (the "answering alongside the turn" notice, which the inline block obsoletes) and `BTW_IN_FLIGHT_TOAST_MESSAGE` (a second `/btw` still gets asked when the turn ends, so its answer lands too). The **two** that stay are exactly the paths where nothing reaches the conversation because the message is dropped: a bare `/btw` (`SIDE_QUESTION_USAGE`) and `BTW_TURN_TOO_LONG_MESSAGE` after the 30 minute hold gives up. That is the rule to apply to any new toast here: if the conversation gets the content, do not also toast it. `showToast` itself stays, and so does the `tui.showToast` receiver-binding care in it (a detached `const show = client.tui.showToast` throws, since the SDK method reads `this._client`). + - **A receipt block goes into the turn the moment the question is sent** ("there should be some feedback of them actually having sent it also in the main", once the toast was gone). `formatInlineAsideAsk()` writes `INLINE_ASIDE_SENT` through the same `deliverAsideInline`, and the answer handler **awaits** that promise before writing the answer, so a receipt can never land under the answer it announces. It carries **no question text**, which is the part to leave alone: the first version echoed the question, and the live run showed why that is wrong, since the model keeps streaming its own text between the two blocks (measured: receipt in the assistant message *before* the tool part, answer in the one after, 13 s later), so the question would appear twice with unrelated output in between. It also means the answer block keeps its existing full `question + answer` shape and its existing marker, so nothing new has to be stripped: a continuation marker (`"▌\n"`) was written and then deleted for exactly that reason.

Read `@opentui/core`'s `src/renderables/Markdown.ts` before touching this (`npm pack @opentui/core`, the sourcemap carries the TS): a blockquote **does** get a real left border (`createBlockquoteRenderable` → `BoxRenderable` with `border: ["left"]`, `paddingLeft: 1`), but `getBlockquoteBorderColor()` reads the **`conceal`** scope, falling back to `default`, while `theme.markdownBlockQuote` / `markup.quote` colours only the quoted **text**. So the one key a theme could plausibly change is the one that does not paint the bar, there is no per-block override, and a custom theme is the operator's config anyway (opencode resolves `theme.theme` as-is, with no merge over a base, so it means copying a whole theme). The session route also runs text through `strip-ansi`, so escape codes are not a way in. `barEveryLine` therefore prefixes **every** line, blank ones as a bare `▌`, so the bar runs the full height. Two facts hold the rendering together, both from the same file: OpenTUI renders a paragraph from `token.raw` **verbatim**, so line breaks survive and nothing reflows; and blockquote content goes through `createMarkdownCodeRenderable(token.text, …)` rather than being re-parsed, so the old shape never rendered nested markdown either and dropping it costs nothing. `INLINE_ASIDE_MARKER` must stay the leading characters after `trimStart()` or `filterSideQuestionHistory` stops stripping the block; `LEGACY_INLINE_ASIDE_MARKERS` keeps the old `> **btw:**` blocks strippable in conversations that predate the change, and a test covers it. - **No toast ever carries the answer** ("so we can get rid of the notification now?", once the inline block worked). Every path that produces an answer now puts it in the conversation, inline or as the held pair, so announcing it as well was duplicate delivery of the *worse* copy: a toast expires, which is the complaint that started this whole redesign. Removed with it: `answerToastMessage` / `answerToastDuration` and the `ANSWER_TOAST_*` sizing constants, `BTW_BUSY_TOAST_MESSAGE` (the "answering alongside the turn" notice, which the inline block obsoletes) and `BTW_IN_FLIGHT_TOAST_MESSAGE` (a second `/btw` still gets asked when the turn ends, so its answer lands too). The **two** that stay are exactly the paths where nothing reaches the conversation because the message is dropped: a bare `/btw` (`SIDE_QUESTION_USAGE`) and `BTW_TURN_TOO_LONG_MESSAGE` after the 30 minute hold gives up. That is the rule to apply to any new toast here: if the conversation gets the content, do not also toast it. `showToast` itself stays, and so does the `tui.showToast` receiver-binding care in it (a detached `const show = client.tui.showToast` throws, since the SDK method reads `this._client`). - - **A receipt block goes into the turn the moment the question is sent** ("there should be some feedback of them actually having sent it also in the main", once the toast was gone). `formatInlineAsideAsk(question)` writes `▌ **btw:** *sent to Claude on the side*` through the same `deliverAsideInline`, and the answer handler **awaits** that promise before writing the answer, so a receipt can never land under the answer it announces. **The receipt quotes the question and the answer block repeats it, and that duplication is deliberate.** It went question-less first, on the reasoning that the answer block carries the question anyway; the maintainer asked for it back ("maybe we should see: ▌ btw: <the text you actually sent here> sent to Claude on the side"), and the ask is right: the prompt box clears on submit and the `/btw` message is dropped, so with no question in the receipt **nothing on screen ever says what was sent**.

Two blockers, both checked rather than assumed on 2026-09-06: opencode's SDK exposes **no** part or message update route (`/session/{id}/message/{messageID}` is read-only, and the full route list has nothing else), and the AI SDK stream has no replace-text event, so the only way to grow a block is to keep its text part open and append deltas to the same id. That is ruled out by stream lifetime: a turn is a run of streams, every proxy tool call ends one, and the receipt lands in the stream *before* the tool part while the answer arrives in the one after, so the part is already closed and drained. What *is* true, and is the part worth keeping if this ever becomes possible: opencode's bridge resolves ids explicitly (`currentTextID(state, event.id)` in `session/llm/ai-sdk.ts`) and every delta this plugin emits carries an explicit id, so two concurrently open text parts are protocol-legal. The blocker is the stream boundary, not the id model. `startTextBlock()` here is single-slot and would also have to stop closing the aside's part.

The next attempt answered it in a child session with a toast, which the maintainer rejected on UX: the toast vanished before it could be read and the child session was not where anyone looked. What holds now rests on measured facts, re-check them before changing it: (1) opencode's TUI sends `session.command` immediately, busy or not (`packages/tui/src/component/prompt/index.tsx`), so `command.execute.before` fires at once; the resulting user message is what gets queued. (2) opencode's loop exits only when `lastAssistant.parentID === lastUser.id` (`session/prompt.ts` `runLoop`), so **any** message added to a busy session, `noReply` included, becomes the turn's next step, and that step is also the one carrying the results of the tools opencode just ran. Answering the aside there swallowed the turn's own continuation: measured live, turn 2's "finished" never appeared. (3) Claude Code answers `side_question` while the main loop is blocked (2.1.258: 2.3 s into a 35 s held tool call). So the hook finds the process by opencode session id (`findActiveProcessBySessionId`, fed by the `opencodeSessionID`/`asideTransport` tags doStream writes on every non-compaction turn), sends the `side_question` **immediately**, remembers the promise per session (`rememberSideQuestionAnswer`), toasts the answer when it arrives if the session was busy, and then **holds the command until `client.session.status()` reports the session idle** before returning, so opencode creates the `/btw` message only after the turn is completely over and runs it as a fresh turn. That turn hits the aside branch in `claude-code-language-model.ts`, which takes the remembered answer (`takeSideQuestionAnswer`) or asks the now idle process, and emits it as the assistant reply at 0 tokens; `filterSideQuestionHistory` keeps the pair out of Claude's prompt, and `collectSideQuestionHistory` feeds earlier pairs to follow-ups. Three traps: the remembered answer is matched by **prefix**, not equality, because opencode-dcp appends `` to the message text (an exact match missed live and the turn re-asked into the single-flight guard); busy must come from `session.status`, not the process's line-listener count, because the listener is detached while opencode runs a tool; and holding the route is fine because opencode already keeps the command route open for a queued prompt (34 s observed) and the TUI's call is fire-and-forget. The hook only intercepts when `registerSideQuestionCommand` returned true, so a user-defined `btw` command keeps opencode's normal behaviour. A no-process `/btw` answers with `BTW_NO_SESSION_MESSAGE` as text, not an error. Tests: `test-btw-command.ts` (hook incl. the held return and the give-up timeout, answer store, history fetch, fake-CLI end to end), `test-side-question.ts`. - **Both lookups the hook makes are racy the instant `/btw` is typed, and losing either race puts the "Queued" bubble straight back.** Reported live 2026-09-06 ("if i do the /btw too soo it still gets queued") and confirmed in `plugin.log`: `btw: no live claude process for session` at 14:04:06, then the same question at 14:04:28 found a process and was answered concurrently. Cause: doStream tags the process (`opencodeSessionID`/`asideTransport`) only where it attaches its line listener, which is **after the whole spawn path**, so on a conversation's first turn there is a multi-second window with nothing to ask; the hook fell through, and the message it let past is exactly what opencode queues. The same shape applies to `session.status`, where a session that opencode has not registered yet is **absent from the map and therefore reads as idle**, so a single early read says "not busy" and the hold is skipped. So `waitForAsideProcess` polls for the process while the session is busy (giving up after `SPAWN_WAIT_MAX_MS`, 30 s, because the running turn may belong to another provider and then no process is ever coming), and `settleSessionBusy` keeps re-reading status for `BUSY_SETTLE_MS` (1.5 s) before it will conclude idle. Two ordering rules hold this together: the settle runs **concurrently** with the request, never before it, or an idle `/btw` would wait out the settle window before being asked at all; and `answer.catch(() => undefined)` goes on immediately, because the settle spans timer ticks and a fast failure (dead process, interactive transport) would otherwise surface as an unhandled rejection in opencode's own process before the real handlers are attached. The suite caught that second one, so do not remove it as dead code. - **The answer is written into the running turn's own reply, and only falls back to the toast plus a held message.** The toast was the delivery while a turn ran, and the maintainer rejected it twice for the same reason ("the notification is too short and is gone right away", then "can you also add it printed to the main thread"): a toast expires, and the held `/btw` pair could not land until the turn was over. So `doStream` registers an `AsideSink` per conversation (`registerAsideSink(affinity, ...)`, unregistered in `cleanupTurn`) that enqueues one finished text block into the live stream, and `deliverAsideInline` uses it; on success the hook throws `BtwHandledError` so opencode never creates the `/btw` message at all, since the answer is already in the transcript. Four things this rests on: (1) the sink is keyed by `affinity`, which **is** the opencode session id, the same key `takeSideQuestionAnswer` uses. (2) `registerAsideSink` returns an unregister that only deletes its own sink, because a turn's cleanup runs after the next turn has already registered. (3) A turn is a **run of streams**, not one: every proxy tool call ends the stream (`finishWithPendingProxyCalls`) and opencode opens the next one with the result, so an answer arriving in that gap has nothing to write to. `deliverAsideInline` therefore retries for `INLINE_WAIT_MAX_MS` (20 s) while the session stays busy and only then falls back to the toast plus the held message, which is still the whole point of keeping that path. (4) The block is its own text part led by `INLINE_ASIDE_MARKER` (`▌ **btw:**`), which is what lets `filterSideQuestionHistory` strip it exactly when a transcript is rebuilt: an aside was never Claude's output and was never in its context. Do not merge it into the model's own text block, and do not match the marker mid-part; the strip is part-level for a reason.

Two facts hold the rendering together, both from the same file: OpenTUI renders a paragraph from `token.raw` **verbatim**, so line breaks survive and nothing reflows; and blockquote content goes through `createMarkdownCodeRenderable(token.text, …)` rather than being re-parsed, so the old shape never rendered nested markdown either and dropping it costs nothing. `INLINE_ASIDE_MARKER` must stay the leading characters after `trimStart()` or `filterSideQuestionHistory` stops stripping the block; `LEGACY_INLINE_ASIDE_MARKERS` keeps the old `> **btw:**` blocks strippable in conversations that predate the change, and a test covers it. + - **The aside's left bar is a literal `▌` the plugin emits, NOT a markdown blockquote.** Asked for "a subtle green border around the full response", and the blockquote answer shipped first and was wrong; it was replaced after the maintainer reported "the theme is picked but nothing green shows up", which is exactly what the source predicts. Read `@opentui/core`'s `src/renderables/Markdown.ts` before touching this (`npm pack @opentui/core`, the sourcemap carries the TS): a blockquote **does** get a real left border (`createBlockquoteRenderable` → `BoxRenderable` with `border: ["left"]`, `paddingLeft: 1`), but `getBlockquoteBorderColor()` reads the **`conceal`** scope, falling back to `default`, while `theme.markdownBlockQuote` / `markup.quote` colours only the quoted **text**. So the one key a theme could plausibly change is the one that does not paint the bar, there is no per-block override, and a custom theme is the operator's config anyway (opencode resolves `theme.theme` as-is, with no merge over a base, so it means copying a whole theme). `barEveryLine` therefore prefixes **every** line, blank ones as a bare `▌`, so the bar runs the full height. + - **The bar is not coloured, and the search for a green one is closed.** Correction to an earlier note here: assistant text is **not** run through `strip-ansi`. That call sites at `packages/tui/src/routes/session/index.tsx:2051,2349` apply to **tool output**; `TextPart` passes the text straight into ``. ANSI is still useless, for a better reason: OpenTUI renders markdown through tree-sitter into its own buffer with its own colours, so escape bytes print literally and corrupt width measurement. Colour in that renderer comes only from syntax scopes, and there is no scope for a plain character in a paragraph: `` `x` `` is `markup.raw`, `**x**` is `markup.strong`, a blockquote border is `conceal` (`Markdown.ts` `renderInlineToken`). Every one of those is theme-wide, so painting the bar green would repaint all inline code, or all bold, or all blockquotes, across every message, and needs a whole copied theme to do it. The only zero-config green is a colour emoji, which the maintainer refused outright ("no emoji please") and which contradicts the original ask for something *subtle*. So the bar stays a plain `▌`. Do not re-open this without a new opencode rendering feature. Two facts hold the rendering together, both from the same file: OpenTUI renders a paragraph from `token.raw` **verbatim**, so line breaks survive and nothing reflows; and blockquote content goes through `createMarkdownCodeRenderable(token.text, …)` rather than being re-parsed, so the old shape never rendered nested markdown either and dropping it costs nothing. `INLINE_ASIDE_MARKER` must stay the leading characters after `trimStart()` or `filterSideQuestionHistory` stops stripping the block; `LEGACY_INLINE_ASIDE_MARKERS` keeps the old `> **btw:**` blocks strippable in conversations that predate the change, and a test covers it. - **No toast ever carries the answer** ("so we can get rid of the notification now?", once the inline block worked). Every path that produces an answer now puts it in the conversation, inline or as the held pair, so announcing it as well was duplicate delivery of the *worse* copy: a toast expires, which is the complaint that started this whole redesign. Removed with it: `answerToastMessage` / `answerToastDuration` and the `ANSWER_TOAST_*` sizing constants, `BTW_BUSY_TOAST_MESSAGE` (the "answering alongside the turn" notice, which the inline block obsoletes) and `BTW_IN_FLIGHT_TOAST_MESSAGE` (a second `/btw` still gets asked when the turn ends, so its answer lands too). The **two** that stay are exactly the paths where nothing reaches the conversation because the message is dropped: a bare `/btw` (`SIDE_QUESTION_USAGE`) and `BTW_TURN_TOO_LONG_MESSAGE` after the 30 minute hold gives up. That is the rule to apply to any new toast here: if the conversation gets the content, do not also toast it. `showToast` itself stays, and so does the `tui.showToast` receiver-binding care in it (a detached `const show = client.tui.showToast` throws, since the SDK method reads `this._client`). - **A receipt block goes into the turn the moment the question is sent** ("there should be some feedback of them actually having sent it also in the main", once the toast was gone). `formatInlineAsideAsk(question)` writes the question on the marker line with the note on its own bar line beneath it, through the same `deliverAsideInline`, and the answer handler **awaits** that promise before writing the answer, so a receipt can never land under the answer it announces. **The receipt quotes the question in full and the answer block repeats it, and that duplication is deliberate.** It went question-less first, on the reasoning that the answer block carries the question anyway; the maintainer asked for it back ("maybe we should see: ▌ btw: <the text you actually sent here> sent to Claude on the side"), and the ask is right: the prompt box clears on submit and the `/btw` message is dropped, so with no question in the receipt **nothing on screen ever says what was sent**. A 240-character `RECEIPT_QUESTION_MAX` was added and then removed for the same reason ("i want the question to hold the full untruncated question"): once the receipt is the only readback, eliding it means a long aside can be read nowhere, and it also produced the odd shape the maintainer spotted, a short copy in the receipt above a full copy in the answer. The reason the answer block must keep its own copy is measured, not stylistic: the model keeps streaming its own text between the two (receipt in the assistant message *before* the tool part, answer in the one after, 13 s later), so a headerless answer arriving after that reads as orphaned. Keeping the answer block's existing shape and marker is also what means nothing new has to be stripped: a continuation marker (`"▌\n"`) was written and then deleted for exactly that reason. - **Updating the receipt in place when the answer lands is not available, do not try again without new evidence.** Asked for directly ("maybe dont want a new block when answer comes in instead update the original"). Two blockers, both checked rather than assumed on 2026-09-06: opencode's SDK exposes **no** part or message update route (`/session/{id}/message/{messageID}` is read-only, and the full route list has nothing else), and the AI SDK stream has no replace-text event, so the only way to grow a block is to keep its text part open and append deltas to the same id. That is ruled out by stream lifetime: a turn is a run of streams, every proxy tool call ends one, and the receipt lands in the stream *before* the tool part while the answer arrives in the one after, so the part is already closed and drained. What *is* true, and is the part worth keeping if this ever becomes possible: opencode's bridge resolves ids explicitly (`currentTextID(state, event.id)` in `session/llm/ai-sdk.ts`) and every delta this plugin emits carries an explicit id, so two concurrently open text parts are protocol-legal. The blocker is the stream boundary, not the id model. `startTextBlock()` here is single-slot and would also have to stop closing the aside's part. Only sent while `busy`, since an idle `/btw` gets its own message a moment later anyway. Live-verified 2026-09-06 on haiku: receipt 0.3 s after the command, answer 13 s later, `/btw` message dropped, turn still delivered its own reply.

And the provider ids are `claude-code-default` / `claude-code-appical`, never a bare `claude-code`, which fails as an opaque `UnknownError` from the message route. -- Prompt/message conversion or compaction transcript behavior: `test-get-claude-user-message.ts`. +- **A `tool_result` may only be sent back for an id THIS CLI process issued** (`cliToolCallIds` on `getClaudeUserMessage`, issue #29 from @nic-lan). opencode runs some tools on its own behalf, notably the `task` call a `subtask: true` command dispatches, and the resumed CLI session never emitted those `tool_use` blocks. Sending a `tool_result` for one is orphaned: Claude cannot resolve the id, so the payload, **which is right there in the envelope**, is unreachable. Reported as "the result is lost"; measured offline on master, the 613-character subagent answer was physically present as `{"type":"tool_result","tool_use_id":"call_X",...}` and simply unusable. Unmatched ids now render as `…` text **before** the trailing user message, which is what makes opencode's own synthetic "Summarize the task tool output above" instruction true. Two things hold this together and both are load-bearing: (1) the gate cannot break the proxy round-trip, because the envelope is **not** how proxy results are delivered. `proc.stdin.write(userMsg)` is the fresh-turn path only; when a pending proxy call has a matching tool-result, doStream returns before that write (`hasMatchedPendingResults`) and the broker resolves the call directly, and on the write path any still-pending call is being **rejected as orphaned** a few lines above. So a tool-result reaching a written envelope is an opencode-side one by construction. (2) `cliToolCallIds` is read from `getPendingProxyCalls(sk)` **before** `userMsg` is built, in both `doStream` and `doGenerate`, because there is an `await` in between; `doGenerate` passes an **empty** set, since it has no proxy wiring and therefore issued no calls at all. Omitting the option keeps the old unconditional block, so a forgotten call site degrades to the status quo rather than hanging the CLI. +- **The fresh-session history fallback must render tool content, not count it.** Second half of issue #29, and worse than reported: `compactConversationHistory`'s `fresh-session` mode filtered to `user`/`assistant`, so a `tool`-role message was dropped **entirely** and even `[Received N tool result(s)]` never appeared. All that survived a subagent was `[Called 1 tool(s): task]`. It now includes `tool` roles and uses `renderMessageContentForCompaction`, the same serializer `/compact` already used, so `[tool_use:name(input)]` and `[tool_result:name]` plus the clipped body survive. Do not "simplify" this back to placeholders; the whole point is that this path is what a fresh CLI process gets when the prior session id is gone. +- Prompt/message conversion or compaction transcript behavior: `test-get-claude-user-message.ts`.

Two blockers, both checked rather than assumed on 2026-09-06: opencode's SDK exposes **no** part or message update route (`/session/{id}/message/{messageID}` is read-only, and the full route list has nothing else), and the AI SDK stream has no replace-text event, so the only way to grow a block is to keep its text part open and append deltas to the same id. That is ruled out by stream lifetime: a turn is a run of streams, every proxy tool call ends one, and the receipt lands in the stream *before* the tool part while the answer arrives in the one after, so the part is already closed and drained. What *is* true, and is the part worth keeping if this ever becomes possible: opencode's bridge resolves ids explicitly (`currentTextID(state, event.id)` in `session/llm/ai-sdk.ts`) and every delta this plugin emits carries an explicit id, so two concurrently open text parts are protocol-legal. The blocker is the stream boundary, not the id model. `startTextBlock()` here is single-slot and would also have to stop closing the aside's part.

And the provider ids are `claude-code-default` / `claude-code-appical`, never a bare `claude-code`, which fails as an opaque `UnknownError` from the message route. -- **A `tool_result` may only be sent back for an id THIS CLI process issued** (`cliToolCallIds` on `getClaudeUserMessage`, issue #29 from @nic-lan). opencode runs some tools on its own behalf, notably the `task` call a `subtask: true` command dispatches, and the resumed CLI session never emitted those `tool_use` blocks.

All that survived a subagent was `[Called 1 tool(s): task]`. It now includes `tool` roles and uses `renderMessageContentForCompaction`, the same serializer `/compact` already used, so `[tool_use:name(input)]` and `[tool_result:name]` plus the clipped body survive.

Since that path is "usable" (not `/`), it won the resolution and **every** Claude subprocess spawned in the wrong directory regardless of which project the web session was for. The TUI was unaffected (its `process.cwd()` is the project), so #4's fix did not cover this. opencode already sets `x-session-affinity: ` on LLM calls (the plugin reads it for process keying) and hands the plugin the SDK client. The opencode `Session` object carries a required `directory` field (`GET /session/{id}`). So: - `runtime-status.ts`: extend the minimal `OpencodeClient` with `session.get`; add `fetchSessionDirectory(id)` (no cache — a session's dir can change on workspace switch and it's a cheap localhost call); add `resolveSpawnCwdForSession()` and a new tier-2 `sessionDir` arg to `resolveSpawnCwdFrom()`. - New priority: explicit pin → **session directory** → live cwd → captured init dir → fallback. Session dir sits above live cwd so serve mode is correct, but below an explicit pin so user overrides still win. - `claude-code-language-model.ts`: both spawn paths (`doStream`, `doGenerate`) now `await resolveSpawnCwdForSession(cwd, affinity)`. Absent session id ("default"), no SDK client, or a failed/again malformed lookup all fall back to the previous behavior, so TUI / direct-AI-SDK / test paths are unchanged. Adds test coverage for the new tier; full suite 124/124.

The plugin additionally re-read ~/.config/opencode/AGENTS.md from disk and appended a second copy, so the file reached the model twice in the claude-code/SDK path. Skip the disk-read copy when the same content is already present in the forwarded system messages. Fail-safe: on no substring match (formatting drift, or the interactive path which forwards an empty extraSystemContent) the previous behaviour is kept, so AGENTS.md is never lost. opencode's policies (instructions[]) live in extraSystemContent and are untouched. Verified (tsx, against the real ~/.config/opencode/AGENTS.md): - forwarded present -> AGENTS.md appears 1x (dedup) - nothing forwarded -> AGENTS.md appears 1x (fail-safe, no loss) - forwarded block (policies) kept intact Umsetzungsuebersicht (Soll/Ist): | Aenderung | Nachher (Plan) | Nachher (Ist) | Ampel | | dedup vs extraSystemContent | AGENTS.md nur wenn nicht forwarded | pushGlobal x3 in dist, typecheck clean | gruen | | bun run build | dist neu | build success 189KB | gruen | | AGENTS.md 1x (Funktion) | 1x | tsx Case1 = 1 PASS | gruen | | interaktiv/leerer Forward | bleibt | tsx Case2 = 1 PASS | gruen | | Policies im Forward | vollstaendig | tsx Case3 PASS | gruen | | Live-SDK-Session 1x | 1x | offen: braucht opencode-Neustart | gelb | | Fremd-Repo-Smoke | vorhanden | offen: braucht Session in anderem Repo | gelb | Local fork patch on top of the submit-plan-proxy branch; upstream-merge risk noted.

The Claude CLI runs one turn per process. Closing the opencode-side stream told it nothing, so an abort only detached our listeners: the CLI ran the abandoned turn to completion (Joseph measured ~7,500 extra characters generated after abort on a haiku probe), kept billing, kept running tools, and its late output landed in the next turn, whose stream the stale `result` then closed early. Now every stdin write that asks for work marks the process in flight, the terminal `result` line clears it, an abort sends a stream-json `control_request` of subtype `interrupt`, and a new turn that finds the previous one still running interrupts it first (5 s cap, then proceeds and logs).

With `bridgeOpencodeSkills: true` the plugin discovers the skills, stages a throwaway Claude plugin directory that links them, and passes it as `--plugin-dir`; they register as `opencode-skills:`. One deliberate difference from the fork: it is opt-in here. Every bridged skill is also listed in the system prompt opencode already forwards, so a large skill set would be paid for twice per turn if this were on by default. --- package.json | 2 +- src/claude-code-language-model.ts | 9 ++ src/cli-version.ts | 34 +++++ src/index.ts | 1 + src/session-manager.ts | 6 + src/skill-bridge.ts | 225 ++++++++++++++++++++++++++++++ src/types.ts | 11 ++ test-skill-bridge.ts | 204 +++++++++++++++++++++++++++ 8 files changed, 491 insertions(+), 1 deletion(-) create mode 100644 src/skill-bridge.ts create mode 100644 test-skill-bridge.ts diff --git a/package.json b/package.json index 883cab0..f2b6be6 100644 --- a/package.json +++ b/package.json @@ -20,7 +20,7 @@ "build": "tsup", "dev": "tsup --watch", "typecheck": "tsc --noEmit", - "test": "tsx --test test-bridge.ts test-broker.ts test-proxy-mcp.ts test-proxy-task.ts test-auto-continue.ts test-has-new-user-content.ts test-get-claude-user-message.ts test-logger.ts test-cli-args.ts test-session-manager.ts test-compaction-model.ts test-tool-mapping.ts test-cwd-resolution.ts test-todo-ledger.ts test-session-affinity.ts test-config-models.ts test-ask-user-question.ts test-claude-session-wrapper.ts test-spawn-env.ts test-respawn.ts test-startup-diagnostics.ts test-subagent-hint.ts test-exit-plan-mode-question.ts test-compress-tool.ts test-agent-models.ts test-side-question.ts test-btw-command.ts test-effort-sessions.ts test-tool-block-index.ts" + "test": "tsx --test test-bridge.ts test-broker.ts test-proxy-mcp.ts test-proxy-task.ts test-auto-continue.ts test-has-new-user-content.ts test-get-claude-user-message.ts test-logger.ts test-cli-args.ts test-session-manager.ts test-compaction-model.ts test-tool-mapping.ts test-cwd-resolution.ts test-todo-ledger.ts test-session-affinity.ts test-config-models.ts test-ask-user-question.ts test-claude-session-wrapper.ts test-spawn-env.ts test-respawn.ts test-startup-diagnostics.ts test-subagent-hint.ts test-exit-plan-mode-question.ts test-compress-tool.ts test-agent-models.ts test-side-question.ts test-btw-command.ts test-effort-sessions.ts test-tool-block-index.ts test-skill-bridge.ts" }, "dependencies": { "@ai-sdk/provider": "^3.0.8", diff --git a/src/claude-code-language-model.ts b/src/claude-code-language-model.ts index cac94c9..917949b 100644 --- a/src/claude-code-language-model.ts +++ b/src/claude-code-language-model.ts @@ -20,6 +20,7 @@ import { getClaudeUserMessage } from "./message-builder.js" import { resolveAgentEffort, resolveAgentModel } from "./agent-models.js" import { parseSideQuestion, requestSideQuestion, collectSideQuestionHistory, SIDE_QUESTION_USAGE, type SideQuestionResult } from "./side-question.js" import { BTW_NO_SESSION_MESSAGE, registerAsideSink, takeSideQuestionAnswer } from "./btw-command.js" +import { resolveSkillPluginDirs } from "./skill-bridge.js" import { parseModelId } from "./models.js" import { QUESTION_TOOL_NAME, @@ -2661,6 +2662,13 @@ export class ClaudeCodeLanguageModel implements LanguageModelV3 { compressionSummary: getCompressionSummary(sk), }, ) + // Opt-in skill bridge (@broskees): stage opencode skills as a + // session-scoped --plugin-dir so Claude's Skill tool can run them. + const skillPluginDirs = await resolveSkillPluginDirs({ + cwd, + cliPath, + enabled: self.config.bridgeOpencodeSkills === true, + }) cliArgs = buildCliArgs({ sessionKey: sk, skipPermissions, @@ -2670,6 +2678,7 @@ export class ClaudeCodeLanguageModel implements LanguageModelV3 { strictMcpConfig: self.config.strictMcpConfig, disallowedTools: allDisallowed.length > 0 ? allDisallowed : undefined, appendSystemPromptFile: systemPromptFile, + pluginDirs: skillPluginDirs, ...self.thinkingCliOptions(), fastMode, cliVersion, diff --git a/src/cli-version.ts b/src/cli-version.ts index 9a52580..4939521 100644 --- a/src/cli-version.ts +++ b/src/cli-version.ts @@ -108,6 +108,40 @@ export function cliSupportsThinking(v: CliVersion | null): boolean { } /** For tests. */ +const flagSupport = new Map>() + +/** + * Probe whether the binary's own `--help` mentions a flag.

tokens**, the unit opencode and models.dev use (`~/.cache/opencode/models.json` has `claude-haiku-4-5 -> {"input": 1, ...}`); opencode divides by 1e6 itself. They were per-token until @CNQQC's PR #25 (merged 2026-08-19), which made every reported session cost 1,000,000x too low — do not "restore" the `1e-6` form. `opusCost` is the real Opus 4.5+ standard price ($5/M in, $25/M out — corrected from a stale legacy $15/$75; Opus 5 keeps it). Haiku ($1/$5), Sonnet ($3/$15), and Fable/Mythos ($10/$50) were already correct. Fable/Mythos 5.1 keep those input/output rates but use a separately published $0.25/M cache-read rate, not 5.0's $1/M. If you add a model, set its cost from the published standard (not Fast Mode) pricing so the `(N×)` suffix stays consistent. **Every entry now carries its published `limit`**, audited against the Anthropic models + pricing docs on 2026-07-26 (the placeholder `output: 16_384` is gone; do not reintroduce it). Two classes of drift were corrected: `claude-sonnet-4-5` and `claude-opus-4-5` claimed a **1M context they never had** — the whole 4.5 generation (including Haiku 4.5) is **200k context / 64k output** — while every 4.6-and-later entry is **1M / 128k**. Release dates for the three dated IDs were also wrong and now match the snapshot suffix (haiku `2025-10-01`, sonnet-4-5 `2025-09-29`, opus-4-5 `2025-11-01`). `test-config-models.ts` pins all thirteen non-fast-model limits, with fast-model limits pinned separately, so a regression fails the suite rather than silently misreporting the context gauge. - **No long-context pricing tier exists — do not add one.** Investigated for issue #24 on 2026-07-26: Anthropic's pricing page has a "Long context pricing" section stating that Claude 4.6 and later include the full 1M window **at standard pricing** ("a 900k-token request is billed at the same per-token rate as a 9k-token request"), with caching and batch discounts unchanged across it. opencode 1.18.5's optional `cost.tiers` / `cost.experimentalOver200K` fields therefore stay unset — populating them would misreport the real price. The premiums that *do* exist are out of scope here: Fast Mode ($10/$50 on Opus 5/4.8, and this plugin never sends `speed: "fast"`), `inference_geo: "us"` (1.1×, not a CLI flag we pass), and partner-cloud regional endpoints (10%, not our path). Re-open only if Anthropic publishes an above-200K rate. A comment above the cost constants in `src/models.ts` records the same finding. - Billing context (researched 2026-06-10, documented in README "Billing change: June 15, 2026"): from 2026-06-15 Anthropic bills `claude -p` / Agent SDK usage (the plugin's default headless `--print` path) against a separate monthly Agent SDK credit on subscription plans (Pro $20 / Max 5x $100 / Max 20x $200), not normal plan limits; API-key auth is unaffected. Same day, `claude-sonnet-4-20250514` / `claude-opus-4-20250514` retire (not registered here, but pass-through overrides could hit them). Fable 5 is included free on plans only through 2026-06-22; after that it needs usage credits. Confirmed failure mechanism: the 400 `Third-party apps now draw from your extra usage...` corresponds to a `rate_limit_event` with `{rateLimitType:"five_hour", overageStatus:"rejected", overageDisabledReason:"org_level_disabled"}` under OAuth subscription auth, so org-level overage/extra usage being disabled can reject requests that do not fit the remaining rolling window. URL redaction was tested and reverted; the opencode repo URL is not the trigger. Interactive mitigation: live bisection showed this plugin's own CLI/AGENTS/continuation prompt succeeds, while opencode's forwarded system prompt payload can trip the usage gate on constrained subscription accounts. Interactive mode therefore intentionally omits the forwarded opencode system prompt by default. Real account-side fixes remain: enable overage/add extra usage, wait for the 5-hour window reset, switch account/org/plan, or use API-key auth. +- **`AGENTS.md` must not reach the model twice** (`buildAppendedSystemPrompt`, cherry-picked from @HeikoAtGitHub's `25260a4`, absorbed 2026-09-06). opencode forwards `~/.config/opencode/AGENTS.md` inside its own system prompt under an `Instructions from:` header, and this plugin also read it from disk and appended it, so every turn paid for both copies (visible in any plugin-driven session's own system prompt). The disk copy is now pushed only when the forwarded `extraSystemContent` does not already contain it; no match keeps the old behaviour, so the interactive transport (which forwards nothing) never loses it. Live-verified: one copy in a 63 KB appended prompt. Test in `test-compaction-model.ts`. +- **Abort sends the CLI an `interrupt` control request** (`interruptTurn` in `session-manager.ts`, adapted from @broskees' `68ed142`, absorbed 2026-09-06). The CLI runs one turn per process and closing our stream told it nothing: an aborted turn ran to completion, billed, executed tools, and its late output plus stale `result` landed in the next turn (Joseph measured ~7,500 characters generated after abort). `noteTurnStarted` marks the process in flight at every stdin write that asks for work (fresh envelope, auto-continue, watchdog re-send), the terminal `result` line clears it inside the `rl` handler in `spawnClaudeProcess` (**not** a permanent `lineEmitter` listener: `listenerCount("line") === 0` is what routes unattended lines to the buffer and what `/btw` reads as busy, so a permanent listener would break both), the abort handler sends `{type:"control_request", request:{subtype:"interrupt"}}`, and a new turn that finds the previous one in flight interrupts it first with a 5 s cap, except tool-result turns where the CLI is legitimately parked in a proxy call. The interactive transport is never marked in flight (its stdin is a TUI). Live-verified on 2.1.258: abort mid-webfetch, `interrupt sent for aborted turn {idle:true}`, next turn clean in 8.5 s. Tests: `test-session-manager.ts`. +- **`idleProcessTimeoutMs`** (cherry-picked from @bernardofortes' `a5f723a`, absorbed 2026-09-06, resolved by hand onto the current tree because his base predated the `--resume` rename and the respawn rework; the commit is still his). Off unless set. Timer armed in `completeResult` after `cleanupTurn`, cancelled by `getActiveProcess`/`setActiveProcess`/`detachActiveProcess`/spawn/exit, unref'd, and it deletes only if the same process object is still registered so a respawn cannot be killed by its predecessor's timer. Session id survives, so the next turn resumes. Tests: `test-session-manager.ts`. +- **Skill bridge is opt-in** (`bridgeOpencodeSkills`, `src/skill-bridge.ts` written by @broskees in `68ed142`, absorbed 2026-09-06). opencode and Claude share the `/SKILL.md` format but not the roots, so opencode advertised skills the CLI's `Skill` tool could not find. The bridge stages a throwaway plugin dir (`skills-` under `pluginTmpDir`, linked, copy fallback for Windows) and passes `--plugin-dir`; the flag has no version marker so `detectCliSupportsFlag` probes `claude --help` (cached). **Deliberately off by default here**, unlike the fork: every bridged skill is also in the system prompt opencode forwards, so a big skill set doubles its cost per turn. Live-verified via `OPENCODE_CONFIG=` on a temp project: 4 skills bridged, `Skill` call rendered as opencode's `skill` tool, token returned. Only `~/.config/opencode/skills` and `.opencode/skills` are roots; `~/.agents/skills` is not opencode's, so those are not bridged. Wired into `doStream`'s spawn only. Tests: `test-skill-bridge.ts`. +- **Two forks independently named the 5-minute proxy wall's timer**, which the 0.15.0 note above says not to claim without evidence: @broskees (`68ed142`) measured a hard 301 s and attributes it to undici's `headersTimeout` and `bodyTimeout` (300 s each) behind Node `fetch` in the CLI's MCP client; @HeikoAtGitHub (`42f426d`) measured 293 to 296 s plus a separate 300 s MCP-idle timer and, like 0.15.0, fixed it with SSE plus progress notifications. Treat 300 s undici as the working explanation; the 0.15.0 fix already covers it. +- **Do not wait for `message_stop` to drain proxy calls.** @broskees' `a44a2dc`: draining only at that boundary deadlocked two ordinary Bash calls until their timeouts fired in succession, because the CLI blocks inside the MCP call before emitting it. Our broker drains as calls arrive; keep it that way. +- **Sweep the forks more often than once a quarter.** @galvani fixed the stale `toolCallMap` re-emission on 2026-05-25 (`2238ed0`) with the same log signature that took until 2026-09-06 to find here. The sweep is cheap: clone, add every fork as a remote, `git cherry origin/master ` per branch (patch-id equivalence, so absorbed cherry-picks do not show), read the bodies of what is left. - `signature_delta` is expected encrypted thinking metadata. Ignore it quietly; do not treat it as an error. - `WebSearch` with the default `"claude"` routing must NOT be forwarded as a tool-call part. opencode has no `WebSearch` registry entry, and (at least as of opencode v1.17.0) the AI SDK rejects unknown tool names with "Model tried to call unavailable tool" even when `providerExecuted: true` — users saw `⚙ invalid` rows on every CLI-internal web search (fixed after v0.8.0). `mapTool` returns `skip: true` for it, and both tool_use sites in `claude-code-language-model.ts` render the query as a `> **Web search:** …` text line instead (gated by `isWebSearchTool` + `isWebSearchHandledByCli` from `tool-mapping.ts`). Explicit opencode-tool routing (`webSearch: ""`) still forwards with `executed: false`. Tests in `test-tool-mapping.ts`. - `tool-input-delta` parts must only be forwarded for tool calls whose `tool-input-start` was actually emitted. opencode's AI SDK bridge (`packages/opencode/src/session/llm/ai-sdk.ts`) resolves delta/end names via `state.toolNames[event.id] ?? "unknown"`; a delta for an unseen id creates a permanently-pending part with `tool: "unknown"` that the TUI renders as `⚙ unknown`. Skipped tools (ToolSearch, TaskCreate/TaskUpdate, CLI-internal WebSearch, AskUserQuestion, ExitPlanMode, proxy tools) stream `input_json_delta` like any other tool_use, so the streaming site in `claude-code-language-model.ts` gates delta forwarding on a `started` flag set only when the input-start part went out (fixed after v0.8.1). Keep accumulating `inputJson` unconditionally — the skip-path text rendering (AskUserQuestion/ExitPlanMode/WebSearch) depends on it. @@ -73,6 +80,7 @@ - Unchanged rationale: opencode's `tools` argument to `doStream` is still intentionally unused — Claude CLI only sees its own built-ins plus MCP servers bridged via `--mcp-config`, so opencode-native tools like `task_status` never reach the model and need no `mapTool` entry. - Re-audit at the next opencode minor bump. The `opencode` field in the startup block names the running version, so an audit starts by reading that. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4. Tests live in `test-cwd-resolution.ts`. + - **Serve mode gets a tier between the pin and `process.cwd()`: the session's own `directory`** (`resolveSpawnCwdForSession` in `runtime-status.ts`, cherry-picked from @galvani's `9e02ce4`, absorbed 2026-09-06). In `opencode serve` / web UI / OpenChamber one long-lived server handles many projects and `process.cwd()` is the server's launch dir, which is "usable", so it won and **every** `claude` spawned there. `GET /session/{id}` carries `directory`; it is fetched per call (no cache, a workspace switch can change it) keyed by the affinity id, and any failure falls back to the old resolution so the TUI path is unchanged. Live-verified: server launched from `/tmp`, session created with `?directory=`, spawn log `cwd` = the project's realpath. `describeSpawnCwd` for the startup block still mirrors the synchronous order only; the session tier is per call and cannot be described at init. - `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. Two reinforcing guards were added after v0.9.1: (1) the deny message explicitly states it is **not a cancellation** and forbids the model from saying the question was cancelled/skipped/declined — this kills the "the user cancelled, so I'll proceed" rationalization the model otherwise narrates; (2) a turn-local latch `AutoContinueState.sawAskUserQuestion`, set when `formatAskUserQuestion` renders, makes `shouldAutoContinueIncompleteTurn` return `{continue:false, reason:"question"}` for the rest of the turn. Without the latch, a short non-`?` trailing line after the question (e.g. "I'll go with the first option.") looked like an incomplete turn, and the auto-continue nudge made the model proceed with no operator input — the exact "I never interacted and it answered itself" symptom. Latch test in `test-auto-continue.ts`. - **The `AskUserQuestion` fallback is currently dormant in headless mode.** Probed 2026-07-26 against Claude Code CLI **2.1.211**: the name is still *known* to the CLI (`--disallowedTools AskUserQuestion` validates silently, while a bogus name prints `matches no known tool`), but the tool is **not offered to the model** under `--print` — a direct "list every tool you can call" returns `Agent, Bash, Edit, Read, ReportFindings, Skill, ToolSearch, Workflow, Write`, and `ToolSearch select:AskUserQuestion` returns nothing. It reads as a TUI-only affordance the headless surface no longer presents. Consequence: with `Question` off (the default), the model has **no** question tool at all and can only ask in prose and end the turn — which is what the deny/markdown path produced anyway, so behavior is unchanged, but do not expect `formatAskUserQuestion` or the auto-continue latch to fire on this CLI. Keep the machinery (older/newer CLIs and the interactive transport may still offer it); just do not treat "the fallback did not render" as a plugin bug without re-running the two probes above. Evidence is model self-report plus the ToolSearch miss, both on haiku. - **Question proxy is blocked upstream — leave it off.** Verified 2026-07-26 on opencode 1.18.5: the proxy delivers correctly but opencode's own `question` TUI form never renders, so an enabled `Question` costs you the working `AskUserQuestion` fallback and gives a silent hang the operator can only escape by interrupting. Proof it is not ours: (a) `github-copilot/gpt-5.5`, a native provider with the plugin nowhere in the path, fails identically (`Tool execution aborted`, `metadata.interrupted: true`, ~27 s); (b) the `part` table shows every `question` call `completed` through 2026-04-25 and every one since 2026-05-18 aborted, i.e. an opencode regression somewhere in v1.14.24…v1.15.5 (note `The user dismissed this question` is a *different*, healthy error — it means the form rendered); (c) a `--pure` (no-plugin) headless `opencode serve` drives the whole server path green — tool blocks, `question.asked` publishes, `GET /question` lists it, `POST /question/{id}/reply` completes the tool with the answer and emits `question.replied`. So the server is fine and only the TUI render is broken. Upstream: anomalyco/opencode issue **#36604** (open) with fix **PR #36603** (`hydratePending()` at TUI bootstrap, open since 2026-07-13, unmerged).

Design and first implementation by Joseph Roberts (@broskees) on his fork, commit 68ed142. Adapted for this tree by Khalil Gharbaoui: the serial premise was re-measured live before building (second MCP request arrived 7 ms after the first resolved), validation happens in the tools/call handler before queueing, a partial set of child results resolves the parent with the gap named rather than erroring, the batch rides along with `Task` in `proxyTools`, and the "unlimited by default" task deadline from the same fork was not taken.

Explicit opencode-tool routing (`webSearch: ""`) still forwards with `executed: false`. Tests in `test-tool-mapping.ts`. - `tool-input-delta` parts must only be forwarded for tool calls whose `tool-input-start` was actually emitted. opencode's AI SDK bridge (`packages/opencode/src/session/llm/ai-sdk.ts`) resolves delta/end names via `state.toolNames[event.id] ?? "unknown"`; a delta for an unseen id creates a permanently-pending part with `tool: "unknown"` that the TUI renders as `⚙ unknown`. Skipped tools (ToolSearch, TaskCreate/TaskUpdate, CLI-internal WebSearch, AskUserQuestion, ExitPlanMode, proxy tools) stream `input_json_delta` like any other tool_use, so the streaming site in `claude-code-language-model.ts` gates delta forwarding on a `started` flag set only when the input-start part went out (fixed after v0.8.1). Keep accumulating `inputJson` unconditionally — the skip-path text rendering (AskUserQuestion/ExitPlanMode/WebSearch) depends on it. - Subagent dispatch must be steered at the tool *and* the prompt (absorbed from @jknlsn's `94980a6`, diagnosed on his fork 2026-07-04, re-confirmed live here 2026-07-26). Headless `--print` Claude Code exposes no `Agent`/`Task` dispatch tool of its own (checked through CLI 2.1.211), so the `task` proxy is the only path — but the CLI *does* expose `TaskCreate`, a todo tool, and models resolve opencode's "call the task tool with subagent: X" mention hint straight to it: a todo appears, nothing runs, and the model narrates a successful dispatch. Since Task is proxied by default (v0.10.0) this is reachable without any config. Two spawn-time countermeasures, both required: `overlayTaskProxyDescription` in `proxy-mcp.ts` front-loads opencode's live agent-type list onto the `task` proxy def, and `SUBAGENT_DISPATCH_HINT` goes into the appended system prompt naming `mcp__opencode_proxy__task` as the only dispatch path. **Claude Code truncates long MCP tool descriptions, so position is load-bearing:** jknlsn's original pasted opencode's entire live description (2858 chars) in front of the static def, but opencode puts "Available agent types" at the *end* of it (char 2306), so the only part the model needed was exactly what got cut. Live-verified failure (2026-07-26, haiku): the model asked for `general-purpose`, then `default`, then `code-reviewer` — Claude Code's own agent names — and every dispatch died with `Unknown agent type`, after which it grepped `~/.config/opencode/opencode.json` and answered the question itself. Fix: `extractAgentTypeList` keeps only the list, trims each blurb to 140 chars, drops opencode's generic preamble, and the overlay puts it **first**; total description stays under ~1.4 KB (a test asserts < 1600). Same prompt then dispatched cleanly on the first try (`subagent_type: general`, real child session, `completed`). If you ever grow that description, re-run the live check — a passing unit test will not catch truncation. The hint's ToolSearch line is load-bearing, not padding: harnesses that defer MCP tool schemas (opencode-dcp does) leave `mcp__opencode_proxy__task` invisible while `TaskCreate` stays visible, which is the worst case for this confusion — the maintainer hit exactly that during the v0.10.0 smoke test. `TASK_PROXY_NOTE` must keep describing the real deadline (60 min, `proxyToolTimeoutMs`) and `background` mode; jknlsn's original said 10 minutes, which predated the per-tool timeouts. Only wired into `doStream`'s spawn path — `doGenerate` has no proxy wiring at all, so it deliberately has no hint. Tests: `test-subagent-hint.ts`. +- **`task_batch` is the only way to run two subagents at once, because the CLI serialises MCP calls** (from @broskees' `68ed142`, adapted 2026-09-06, his design). Measured before building it, not assumed: haiku asked for two parallel `mcp__opencode_proxy__bash` sleeps emitted **both tool_use blocks in one assistant message** (same `message.id`, 275 ms apart), yet the second MCP request reached the proxy 7 ms **after** the first resolved, 8 s later. So "call task twice" is serial by construction and no amount of prompting fixes it. `task_batch` (`proxy-mcp.ts`) is one MCP call whose `tasks` array `finishWithToolCalls` fans out as N `task` tool-calls in the **same** stream finish, ids `${parent}_task_${i}` (`taskBatchChildToolCallId`), which opencode runs concurrently as one step; `extractPendingProxyResultForCall` gathers the children's results back onto the parent id (`formatTaskBatchResults`, labelled in order) and resolves the one broker call. Invariants: (1) it rides along with `task` in `resolvedProxyTools`, so `proxyTools: ["Task"]` gets both and nobody has to know it exists; it disables the same built-in (`Agent`), deduped. (2) The batch is validated in the `tools/call` handler **before** it is queued (`taskBatchInputError`), as an MCP `isError` result, since a bad batch has nothing to fan out and a broker entry for it would only time out. (3) A partial set of child results still resolves the parent, with the gap written into the text as `[missing]`: returning null there would send the turn down the fresh-envelope path, which rejects the parent as orphaned and renders the children as text, the worst of both. opencode hands all of a step's results to the next call together, so partial is theoretical. (4) The `TASK_PROXY_NOTE`, the batch def's note, and `SUBAGENT_DISPATCH_HINT` all name it, because the model has to be told the serial behaviour exists to prefer the batch. Deliberately **not** taken from the fork: the "unlimited by default" task deadline (`dd494a8`), which contradicts the documented 60-minute `proxyToolTimeoutMs` contract. Tests: `test-proxy-mcp.ts` (def, validation, deadline, formatter), `test-subagent-hint.ts`, `test-proxy-task.ts` (fake-CLI fan-out and the two-turn gather). **Live-verified 2026-09-06** on Claude Code 2.1.258 + opencode 1.18.29 (haiku, two `general` subagents): `plugin.log` shows exactly one `proxy-mcp tool call received` with `toolName: task_batch` and zero plain `task` calls, the parent holds two `task` tool parts with ids `_task_0` / `_task_1` that started 13 ms apart and overlapped for their whole 5.6 s / 5.8 s runs, two child sessions exist, and the final answer quoted both subagents' tokens. That overlap is the fingerprint: if the two child intervals ever stop overlapping, the fan-out has silently become serial again. - **`toolCallMap` is keyed by content-block index and MUST be deleted at `content_block_stop`.** Claude CLI restarts block indices at 0 on every assistant message, and one turn routinely holds several (tool_use -> tool_result -> answer, `numTurns: 2`). The entry was never deleted, unlike its neighbours `reasoningIds` and `textBlockIndices`, so message 2's answer-text block at index 0 hit message 1's stale tool_use entry and re-emitted a `tool-call` for an id opencode had already completed. That second part never receives a `tool-result`, so opencode aborts it at stream end with `Tool execution aborted` / `interrupted: true`, and opencode's `task` tool turns that abort into `Subagent failed (task_id: ...)` **even though the child answered correctly and finished with `stop`**. Diagnosed live 2026-09-06 on 0.15.0: three probes, deterministic — a subagent using any provider-executed tool failed, a subagent using no tools returned fine. The plugin log is the tell: two `tool call complete` lines with the same `id`, the second ~2 ms after the final text ends. This was NOT a 0.15.0 regression (aborted parts go back to at least 2026-08-16) and it silently produced the long-standing background noise of `⚙ aborted` rows in the main lane too; it only became a hard failure through the `task` tool. Do not "tidy" the delete away. Test: `test-tool-block-index.ts`, which fails with `got 2` without it. - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry. They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - proxy-mcp `tools/call` responses MUST be MCP results (`{ result: { content, isError } }`), never JSON-RPC error envelopes. Claude CLI validates every `tools/call` response against the MCP result schema and rejects JSON-RPC errors as a "malformed result that failed schema validation" (seen live 2026-07-04 on broker timeouts/orphans — fixed post-0.9.2). All three error paths in `src/proxy-mcp.ts` now return results with `isError: true`: unknown tool, `result.kind === "error"` (merged into the success path), and the outer `catch` when `requestMethod === "tools/call"`. Non-`tools/call` methods (initialize, tools/list) and unparseable requests still use JSON-RPC errors, which is spec-correct. `requestId`/`requestMethod` are hoisted above the try so the catch can echo them — do not regress to `id: null`.

Omit it to create a fresh child. - **Nested tasks:** current opencode defaults `subagent_depth` to `1`, so a first-level child cannot launch another child. Increase top-level `subagent_depth` to permit deeper nesting, and explicitly grant `permission.task` on every subagent that should delegate; opencode otherwise adds a task deny to spawned subagent sessions. - **Background:** `background: true` returns after starting the child and lets opencode notify the parent when it finishes. Current opencode requires `OPENCODE_EXPERIMENTAL_BACKGROUND_SUBAGENTS=true` in the environment of the opencode process. Foreground is the default. +- **Several at once:** `mcp__opencode_proxy__task_batch` takes a `tasks` array of ordinary task inputs and runs them concurrently. It exists because Claude Code sends MCP requests one at a time: when the model emits two `task` calls in one response, the second only leaves the CLI after the first has returned (measured live, 2026-09-06), so "launch two subagents" was always serial. The plugin turns one `task_batch` call into N opencode `task` calls inside a single tool boundary, which opencode executes in parallel, then hands the model every result together, labelled in task order. Same permissions, same 60-minute deadline, same `subagent_type` list. Enabled whenever `Task` is proxied.

Subscription headless +usage draws on Agent SDK credit/extra usage under Anthropic's billing policy, not a +promise of free or normal interactive-plan usage. API-key/cloud billing depends on +the CLI's authentication. Confirm the user's intended account and billing method. + +This file ships with the package, so upgrading that package updates the bundled +reference without a separate skill install. Do not copy it into a personal skill +directory: a user override can shadow the bundled version. Match guidance to the +version actually loaded, not a newer checkout. `test-configure-skill.ts` checks name +coverage against source declarations; it does not verify defaults or runtime +semantics or regenerate prose. For behavior, inspect the matching version's +`src/types.ts`, consumers in `src/index.ts` / `src/claude-code-language-model.ts`, and +the relevant module. Comments and README can lag the implementation. + +## Ground rules + +1. **Config lives in opencode's config, not in a plugin file.** Start at + `provider.claude-code.options`. Global defaults usually live in + `~/.config/opencode/opencode.json[c]`; project `opencode.json[c]` and `.opencode/` + files can override them. Check `OPENCODE_CONFIG`, `OPENCODE_CONFIG_DIR` and + `XDG_CONFIG_HOME` before selecting a file. With `accounts`, the seed options are + inherited; an existing `provider.claude-code-.options` can override them. +2. **Provider options are read once, at opencode startup.** After any change the user must fully + quit and relaunch opencode. A plain `/new` session is not enough, and every other + opencode window still open keeps running the old configuration and the old plugin + code. Include serve/GUI processes. Say this every time you change something. + Bridged MCP config has a limited next-turn hot reload, not general config reload. +3. **Edit minimally.** Keep the user's comments in `.jsonc`, keep key order, change only + the keys asked for, and re-parse afterwards. Use surgical text edits or a + JSONC-aware edit API. This package already depends on `jsonc-parser`: its `modify` + and `applyEdits` preserve unrelated text; `parse` must be checked for errors + (`allowTrailingComma: true` for JSONC). Never strip comments with regex or round-trip + JSONC through `JSON.stringify`; that can corrupt URLs or erase comments. +4. **Never edit `dist/`, `node_modules/`, or `~/.cache/opencode/packages/`** to change + behavior. Build output and installer caches are not configuration. +5. **No credentials exposure.** Never read or print auth files, tokens, keys, a full + environment dump, or generated MCP configs. Check credential presence only, not + values. Config, diffs and logs can contain secrets or private prompts; inspect only + relevant fields and redact before displaying or sharing. Leave secret references + such as `{env:NAME}` intact. Do not initiate login/account switching without approval. +6. **No paid probes or risky changes without explicit approval.** Do not run inference + (`claude -p`, `opencode run`, `/btw`), enable extra usage, change billing, grant broad + tool permissions, or enable experimental flags as a routine verification step. + Explain consequences first, including `Question`, `planModeQuestion`, `Compress`, + `interactive`, skill/MCP bridging and fast models. Ask in ordinary text if a decision + is needed; do not use the known-broken question form to configure itself. + +## Procedure + +1. Identify install source/version, config scope, account/provider and requested change. + Inspect relevant config layers without exposing secrets. Preserve unrelated work. +2. If installation is requested, add the scoped package to the existing `plugin` array, + not a replacement array. Preserve pins and `file://` installs unless upgrading was + requested. A local checkout entry is `file:///abs/path/to/opencode-claude-code-plugin`. +3. Edit only the needed options/agent keys. Do not populate every default or invent + plugin-level options, `apiKey`, model metadata, or derived account fields. +4. Validate syntax and the opencode schema (`https://opencode.ai/config.json` when + needed). Schema validation alone does not validate this plugin's free-form options; + check this reference and source for names, types, units and enums. +5. Review the minimal, redacted diff. Report what changed and any unverified behavior. +6. Tell the user to fully restart opencode. Prefer offline checks below; get approval + before launching another opencode process, which may also start configured MCPs. + +## Options reference + +Use `provider.claude-code.options` unless intentionally overriding an expanded account. +Defaults below describe normal headless opencode use when the key is absent. + +| Option | Type | Default | What it does | +|---|---|---|---| +| `cliPath` | string | `"claude"` | Executable, not a shell command with flags.

Account providers wrap it; never select a generated wrapper yourself. | +| `accounts` | string[] | unset | Unset keeps provider `claude-code`. Any array, including `[]`, expands to `claude-code-default` plus normalized, deduplicated names. Non-default accounts use `~/.claude-`; default uses the CLI's normal environment/auth. | +| `defaultSubagentModel` | string | unset | Seed-config default for discovered `mode: subagent` agents without a full `provider/model` pin; `forceModel` takes precedence. Keeps the caller's account. Unknown ids warn and keep the inherited model. Not independently read per expanded account. | +| `cwd` | string | automatic | Pin an absolute existing directory. Otherwise: session directory from SDK, usable `process.cwd()`, captured project directory, final `process.cwd()` fallback. Startup diagnostics cannot show the per-call session tier. | +| `skipPermissions` | boolean | `true` | Pass `--dangerously-skip-permissions` to headless Claude, even with proxies enabled. Proxied calls still use opencode permissions, but unproxied CLI tools do not. `false` removes the bypass flag; it does not by itself create human approval prompts. | +| `permissionMode` | `acceptEdits` / `auto` / `bypassPermissions` / `default` / `dontAsk` / `plan` | unset | Headless `--permission-mode`, not version-gated: verify the installed CLI supports the value. Does not negate `skipPermissions: true`; never assume `plan` makes that combination read-only. Not forwarded by the current interactive spawn path. | +| `controlRequestBehavior` | `allow` / `deny` | `allow` | Automatically answer CLI `can_use_tool` requests if emitted. Not an opencode permission prompt or a sandbox; bypass/pre-allowed tools may never ask. `AskUserQuestion` defaults to deny. | +| `controlRequestToolBehaviors` | object of tool name to `allow`/`deny` | unset | Case-insensitive per-tool override of the above (`Bash`, `Read`, `mcp__github__list_prs`). Do not allow `AskUserQuestion`: that can let headless Claude self-answer. | +| `controlRequestDenyMessage` | string | built-in text | Override ordinary deny text. `AskUserQuestion` always uses its own stop-and-wait message. | +| `proxyTools` | string[] | `["Bash", "Edit", "Write", "WebFetch", "Task"]` | Case-insensitive replacement list, not additive and not a capability allowlist. Known entries expose `mcp__opencode_proxy__`; omitted/unknown tools are not disabled. `Task` also brings `task_batch`; `[]` disables this list, not MCP proxying. See the proxy table for exceptions. | +| `extraDisallowedTools` | string[] | unset | Claude built-ins to switch off outright with `--disallowedTools`, for tools that have no proxy (`["NotebookEdit"]`). Removes the capability rather than routing it. | +| `proxyToolTimeoutMs` | object of proxy tool name to ms | unset | Positive deadlines, case-insensitive keys. Fallback 10 min (including dynamic MCP tools); `task` and `task_batch` 60 min each; `question` 30 min. Set both task keys to override both. Zero/negative values do not disable deadlines; values above 2147483647 are clamped. Bash `input.timeout` raises the resolved deadline, but executor/client ceilings still apply. `compress` is intercepted without a deadline. | +| `planModeQuestion` | boolean | `false` | Bridge `ExitPlanMode` approval to opencode's `question` and return a real CLI tool result. Requires a live question registry entry; otherwise keeps text fallback. Keep off on affected opencode builds: the form has failed to render (anomalyco/opencode#36604). Prose yes/no is not a verified CLI plan-mode unlock. | +| `webSearch` | `"claude"` / `"disabled"` / `""` | `"claude"` | Default: CLI search with the query rendered as text. Custom target forwards a tool call to an existing opencode tool accepting `query`; this is mapping, not the authenticated proxy replacement, so do not assume CLI search is suppressed. `"disabled"` disallows headless `WebSearch`. | +| `bridgeOpencodeMcp` | boolean | `true` | Discover/translate disk MCP config plus runtime enabled status. False stops this bridge, not explicit `mcpConfig`, the built-in-tool proxy, or Claude's own MCP settings. Only bridge trusted servers. | +| `mcpConfig` | string or string[] | unset | Extra `--mcp-config` paths or inline JSON passed alongside the bridged config. | +| `strictMcpConfig` | boolean | `false` | Headless `--strict-mcp-config`: use only explicitly supplied MCP configs, ignoring other MCP sources, not all settings/credentials/hooks. The interactive wrapper adds it whenever it passes MCP paths, independently of this option. | +| `hotReloadMcp` | boolean | `true` | With bridging on, compare merged MCP config/status at turn start and respawn on drift after pending proxy calls resolve. Keeps the session via headless `--resume`. Does not reload arbitrary provider options or watch explicit `mcpConfig` contents. | +| `proxyOpencodeMcpTools` | boolean | `true` | When bridge and live tool discovery succeed, route discovered MCP tools through opencode's executor. Disabled/unavailable discovery falls back to direct CLI bridging. Do not promise exactly-once side effects across failures/retries or opencode versions; verify routing before using write-capable tools. | +| `multiStepContinuation` | boolean | `true` | Append a system-prompt hint to chain tool calls in one turn instead of stopping between subtasks. | +| `autoContinueIncompleteTurns` | boolean or `"smart"` | `"smart"` | `true`/`"smart"` enable the same bounded heuristic only when stop reason is missing. Any stop reason (even `max_tokens`), error, abort or latched question stops it. Current measured CLIs always report a reason; not a guaranteed auto-resume. | +| `compactionModel` | string | `"claude-haiku-4-5"` | `/compact` uses a fresh short-lived headless process without the usual bridge/proxy/skill wiring. Nonblank `CLAUDE_CODE_COMPACTION_MODEL` wins. This is inference and can be billed. | +| `ignoreAnthropicApiKey` | boolean | `false` | Strip `ANTHROPIC_API_KEY` and `ANTHROPIC_AUTH_TOKEN` from headless/interactive spawn env, allowing stored auth to be used. Does not log in, change the parent env, or guarantee subscription billing if other CLI/cloud auth is configured. Warns at startup when either nonempty variable is present, regardless of the flag. | +| `idleProcessTimeoutMs` | number | unset | Kill a conversation's idle `claude` worker this many ms after a finished turn. The session id is kept, so the next message resumes transparently. `0` or unset keeps workers until LRU eviction (16 processes). Values above `2147483647` are ignored. Not applied to the interactive transport. | +| `bridgeOpencodeSkills` | boolean | `false` | Opt-in user skill staging for ordinary headless streams, as `opencode-skills:`. Requires the CLI's `--help` to advertise `--plugin-dir`; otherwise no-op. Adds prompt overhead and exposes skill instructions to Claude. Bundled skill staging does not require this opt-in, but still requires flag support and successful discovery/staging. | +| `interactive` | boolean | unset (headless) | Experimental PTY transport; explicit boolean wins over `CLAUDE_CODE_INTERACTIVE_TRANSPORT`. Needs `Bun.Terminal`; otherwise headless fallback. Compaction stays headless. Does not wire the headless proxy server/skill bridge/disallowed-tools controls; no equivalent opencode permission guarantee or `/btw`. Never enable to bypass a billing/access restriction. | +| `interactiveBypass` | boolean | `false` | Deprecated no-op. The TUI asks for a manual safety confirmation on `bypassPermissions`, so the plugin never passes it. | +| `interactiveAllowTools` | string[] | `["Bash", "Edit", "Write", "Read", "WebFetch"]` | With `interactive`: replaces the built-in pre-allow list. MCP wildcards from discovered bridge names plus `mcp__opencode_proxy__*` are added even with `[]`. Not a capability denylist; review permissions before enabling. | +| `interactiveSystemPrompt` | boolean | `true` | With `interactive`: append the plugin's own prompt. opencode's forwarded system prompt is deliberately not sent on this transport (it can trip Claude's third-party usage gate). `false` is for diagnostics only. | +| `logging` | object | see below | File and TUI logging policy. | +| `name` | string | unset | Low-level `createClaudeCode()` provider identity fallback after `providerID`, not the opencode display-name setting. Display name lives at `provider..name`; account expansion supplies its own label. Leave this option unset. | +| `providerID` | string | derived | Config hook writes the actual provider id (`claude-code` or `claude-code-work`). Do not override manually. | +| `account` | string | unset/derived | Account expansion supplies this to generate its runtime wrapper. Prefer `accounts` over hand-wiring it. | +| `configDir` | string | unset/derived | Generated account directory, also used for interactive env/transcript lookup. Not a standalone headless auth switch: headless account selection comes from the wrapper's env. Do not hand-wire it. | + +### `logging` object + +| Key | Values | Default | Effect | +|---|---|---|---| +| `file` | boolean | `false` | Persist entries that pass `level`. Logs can contain prompts/tool data/CLI arguments; enable temporarily with consent, not as a credential dump. | +| `dir` | path | `~/.local/share/opencode-claude-code/` | Where `plugin.log` goes. | +| `mode` | `"silent"` / `"debug"` | `"silent"` | After level filtering: silent routes lower levels only to the file if enabled; WARN/ERROR go to stderr/TUI too. Debug echoes all emitted levels to stderr, but does not lower the threshold. | +| `level` | `debug` / `info` / `notice` / `warn` / `error` | `"info"` | Minimum level emitted anywhere. | + +## Environment variables + +Set variables in the environment that launches opencode, then fully restart it. +Precedence is per variable, not a blanket env-over-config rule. CLI-owned variables +are passed through; their final effect depends on the installed CLI. Never print +their secret values. Arbitrary MCP `{env:NAME}` placeholders are outside this list. + +| Variable | Effect | +|---|---| +| `CLAUDE_CLI_PATH` | Direct factory fallback for absent `cliPath`. Normal opencode registration supplies `"claude"`; set the option explicitly there. | +| `CLAUDE_CONFIG_DIR` | CLI auth/settings/session directory. Non-default account wrappers override it; default headless account inherits it if set. Login is a user-approved interactive action, never a diagnostic probe. | +| `CLAUDE_CODE_EFFORT_LEVEL` | Shell-level CLI effort. Request variant/agent effort wins on a normal spawn. Compaction omits request/agent effort, but still inherits the shell env. | +| `CLAUDE_CODE_DISABLE_THINKING` | CLI-owned, conventionally `1` to disable thinking. Plugin leaves it intact and suppresses its own thinking flags/summary defaults if enabled. | +| `CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING` | CLI-owned adaptive-thinking control. Either disable variable suppresses the plugin's own thinking flags/summary defaults, not just adaptive flags. Empty/`0`/`false`/`no`/`off` are false, case-insensitive. | +| `CLAUDE_CODE_SHOW_THINKING_SUMMARIES` | Headless spawn fills in `1` only if unset and neither disable flag is enabled. Any explicit value is preserved and suppresses the plugin's `--thinking-display` override; `0` requests suppression from the CLI. | +| `CLAUDE_CODE_COMPACTION_MODEL` | Nonblank, trimmed value wins over `compactionModel`. | +| `CLAUDE_CODE_DISABLE_FAST_MODE` | CLI-owned kill switch, conventionally `1`; plugin does not interpret it or change picker prices. Use the non-fast id if fast mode is disabled. | +| `CLAUDE_CODE_INTERACTIVE_TRANSPORT` | Fallback when `interactive` is absent: `1` enables; empty/`0`/`false`/`no`/`off` disable (case-insensitive). Explicit `interactive: false` wins. | +| `CLAUDE_CODE_INTERACTIVE_BYPASS` | Deprecated no-op, like `interactiveBypass`. | +| `CLAUDE_CODE_START_WATCHDOG_MS` | Positive integer ms before a headless start or proxy-result continuation is considered silent; default 90000 for missing/invalid/nonpositive values. First expiry respawns, second errors. Bookkeeping-only output is not progress. Keep within timer range; do not lower for routine config checks. | +| `OPENCODE_CLAUDE_CODE_LOG_FILE` | Overrides `logging.file`: trimmed `0/false/no/off` are false; any other nonempty value is true; empty falls back to config. Prefer `1` or `0`. | +| `OPENCODE_CLAUDE_CODE_LOG_DIR` | Overrides `logging.dir`. | +| `OPENCODE_CLAUDE_CODE_LOG_LEVEL` | Overrides `logging.level`. Invalid values fall through to config. | +| `DEBUG` | A value containing `opencode-claude-code` promotes `logging.mode` to debug, not `logging.level`. Preserve other debug namespaces. | +| `OPENCODE_CLAUDE_CODE_PLUGIN_NO_CLEANUP=1` | Skip the one-time removal of a stale unscoped `opencode-claude-code-plugin` install from opencode's package cache. | +| `ANTHROPIC_API_KEY` | CLI API authentication input, stripped when `ignoreAnthropicApiKey` is true; otherwise may change billing away from stored subscription auth. Never display it. | +| `ANTHROPIC_AUTH_TOKEN` | CLI auth-token input; same strip/warning rule. Never display it. | +| `OPENCODE_CONFIG` | Explicit config file, also read by the disk MCP bridge before project layers. | +| `OPENCODE_CONFIG_DIR` | Additional `.opencode`-style config/skill root. The plugin's direct agent-file fallback does not use it; agents must reach the config hook or a supported agent directory. | +| `OPENCODE_WORKTREE` | Overrides the disk MCP bridge's project walk-up boundary. | +| `XDG_CONFIG_HOME` | Global MCP/skill/AGENTS discovery root (`/opencode`); defaults to the home `.config`. Direct agent-file fallback still uses `~/.config/opencode/agent(s)`. | +| `XDG_CACHE_HOME` | Account wrapper/cache-cleanup root override; do not assume the default cache path when upgrading. | +| `HOME` | Home expansion and direct agent-file discovery (other paths also use OS homedir). Do not change it to switch accounts. | +| `USERPROFILE` | Home fallback where `HOME` is absent. | +| `OPENCODE_VERSION` | Startup diagnostics version fallback, not a capability override. | + +## Recipes + +### Minimum install + +```json +{ "plugin": ["@khalilgharbaoui/opencode-claude-code-plugin"] } +``` + +Everything else is optional. Models appear in the picker without extra config. + +### Two accounts + +```json +{ + "provider": { "claude-code": { "options": { "accounts": ["personal", "work"] } } } +} +``` + +Creates `claude-code-default`, `claude-code-personal`, `claude-code-work`; default +models have no suffix, other accounts have `@` (`claude-opus-5@work`). Names +normalize to lowercase hyphen-separated ids, so choose distinct simple names. +After the user approves login, they authenticate each non-default account interactively, +for example `CLAUDE_CONFIG_DIR="$HOME/.claude-work" claude auth login`, using the chosen +binary. Never copy credentials between accounts. The generated wrapper strips the model +suffix and sets the config dir. Existing `CLAUDE.md`, `settings.json`, `skills/`, +`agents/`, `commands/`, `plugins/` in `~/.claude` are symlinked only when targets are +missing; existing targets stay untouched. This shares capabilities/settings, not an +isolation boundary. Auth/session files are not part of the shared list. + +### Subagents on one model, on the caller's account + +opencode's agent config cannot say "inherit the account, change the model", because the +account is the provider and the model is only a `--model` flag. The plugin closes that gap. + +Per agent, in `~/.config/opencode/agents/.md` or `.opencode/agents/.md` +(`agent/` singular also works), no `model:` key: + +```yaml +--- +description: Designs and builds UI work +mode: subagent +forceModel: claude-haiku-4-5 +reasoningEffort: high +--- +``` + +Or once for every discovered subagent without a full provider/model pin: + +```json +{ "provider": { "claude-code": { "options": { "defaultSubagentModel": "claude-opus-5" } } } } +``` + +Rules, in order: `forceModel` wins; else `mode: subagent` with `defaultSubagentModel` +set; else untouched. An agent with `model: /` is left exactly as written, +account and all (`model: claude-code-work/claude-opus-5@work` pins the account too). +Undeclared built-ins are not discovered; a user definition with a built-in name can +enter the registry and is subject to these rules. This is not a built-in-name denylist. +`reasoningEffort` in the agent file beats the effort the call arrived with; compaction is +exempt. Effort and model are part of the CLI session key, so a changed agent respawns +rather than sharing a process. + +Only grant `permission.task` for approved target agents if delegation is wanted. +`permission.todowrite: "allow"` is needed for subagent todos; opencode otherwise denies +them by default. Ask before broadening permissions. Use the singular `agent` config +object for inline definitions, with `forceModel`/`reasoningEffort` under `options` if +the opencode schema requires it. Markdown fallback reads top-level scalar fields only. + +### Agent keys + +| Key | Behavior | +|---|---| +| `mode` | Only exactly `subagent` qualifies for `defaultSubagentModel`; `primary`/`all` do not. | +| `model` | Full `provider/model` pins bypass plugin model overrides, not the separate effort override. | +| `forceModel` | Registered bare model id, preserving the caller's account even if an account suffix is supplied. Works for any discovered agent mode. | +| `reasoningEffort` | `minimal`, `low`, `medium`, `high`, `xhigh`, `max`; invalid declarations warn and keep inherited effort. `minimal` maps to CLI `low`. Compaction skips this override. | + +### Route a tool through opencode, or switch one off + +```json +{ "proxyTools": ["Bash", "Edit", "Write", "WebFetch", "Task"], "extraDisallowedTools": ["NotebookEdit"] } +``` + +Options fragments in recipes belong inside `provider.claude-code.options`, not at +the config root. Preserve other wanted proxies when changing this replacement list. +`Read`, `Glob` and `Grep` have tool mappings/disallowed-name entries but no selectable +proxy definitions in this version, just like `NotebookEdit` has no proxy. Adding them +to `proxyTools` warns and leaves the built-ins unproxied. Use `extraDisallowedTools` +only to deliberately remove a capability; omission from `proxyTools` is not denial. + +The proxy's loopback endpoint has bearer, Host, Origin and Content-Type guards. +Never weaken them, publish its token or relax the generated MCP file's `0600` mode. +Restart all old processes after a security upgrade; changing files cannot patch them. + +### Proxy tool names + +Names below become `mcp__opencode_proxy__`; input config is case-insensitive. + +| Tool | Selection and behavior | +|---|---| +| `bash` | `"Bash"`, default; replaces CLI Bash with opencode execution. | +| `edit` | `"Edit"`, default; replaces CLI Edit. | +| `write` | `"Write"`, default; replaces CLI Write. | +| `webfetch` | `"WebFetch"`, default; replaces CLI WebFetch. | +| `task` | `"Task"`, default; disables CLI Agent and dispatches opencode subagents under its permissions. | +| `task_batch` | Included with Task; one MCP call fans out two or more independent task inputs concurrently. Separate task calls were measured serial on CLI 2.1.258. | +| `question` | `"Question"`, opt-in; replaces AskUserQuestion only if the live opencode registry has question. Requires `permission.question`; form rendering is broken on affected versions, so keep off. | +| `compress` | `"Compress"`, opt-in; in-process summary/reset interceptor, no opencode permission prompt and no built-in replacement. Discards prior CLI detail on a later eligible turn, retaining the summary, not the full transcript. Keep off unless explicitly requested; end-to-end reset remains unverified live. | + +### Let Claude load the user's opencode skills + +```json +{ "bridgeOpencodeSkills": true } +``` + +Use only after approval when `Skill("")` fails for a trusted opencode skill. +Headless bridged names are `opencode-skills:`, including this bundled skill as +`opencode-skills:claude-code-plugin`. The package also registers its skill directory +with opencode's `skills.paths`; older opencode versions may not support that surface. +The native Claude bridge needs `--plugin-dir` support and is wired into ordinary +headless streaming calls, not interactive, compaction or direct `doGenerate` calls. +The bundled skill does not require `bridgeOpencodeSkills: true`; that option adds +the user's skills. Reusing a process does not load a new skill catalog. + +User roots: `.opencode/skills` walking from cwd to filesystem root, home `.opencode/skills`, +`OPENCODE_CONFIG_DIR/skills`, then `XDG_CONFIG_HOME/opencode/skills` (home `.config` +fallback). First name wins; enabled user bridging can shadow bundled names. Only immediate +`/SKILL.md` directories are collected. Arbitrary `skills.paths`, `skills.urls`, +singular `skill/`, `~/.agents/skills` and `~/.claude/skills` are not scanned by this +bridge; Claude can already discover its own skills independently. Broad bridging can +duplicate advertised skill context and exposes every discovered skill, not just one. + +### Free idle workers + +```json +{ "idleProcessTimeoutMs": 900000 } +``` + +Fifteen minutes after a turn ends with no new message, that conversation's `claude` +process exits; the next message resumes the same conversation. + +### Different `/compact` model + +```json +{ "compactionModel": "claude-sonnet-5" } +``` + +This is more expensive per token than the Haiku default, not a cost-saving recipe. + +### Debug logging + +```json +{ "logging": { "file": true } } +``` + +Default destination: `~/.local/share/opencode-claude-code/plugin.log` (respect the +configured/env directory). INFO is enough for startup diagnostics. Add +`"level": "debug"` only if needed for lower-level events; `mode: "debug"` alone does +not do that. Capture a bounded, redacted excerpt, then disable temporary logging and +restart. Logs rotate above 5 MB to `plugin.log.1`, which can also contain private data. + +### Upgrade the plugin + +A published version does not reach a running opencode. First distinguish an npm pin, +npm latest resolution, and a local `file://` install. Preserve a pin unless the user +requested changing it. Some opencode versions freeze latest in +`~/.cache/opencode/packages/@khalilgharbaoui/opencode-claude-code-plugin@latest/`. +Inspect the actual cache location/package identity and get approval before removing +only that stale package directory, never the whole cache or auth/session directories. +Respect platform/XDG paths. Then fully relaunch. A `file://` install uses the checkout's +`dist/`: rebuild with `npm run build` and restart after approval, not cache deletion. +No manual skill copy/update is needed. Do not publish or release as part of configuring. + +## Models and variants + +### Registered model ids + +Registered ids: `claude-haiku-4-5`, `claude-sonnet-4-5`, `claude-sonnet-4-6`, +`claude-sonnet-5`, `claude-opus-4-5`, `claude-opus-4-6`, `claude-opus-4-7`, +`claude-opus-4-8`, `claude-opus-4-8-fast`, `claude-opus-5`, `claude-opus-5-fast`, +`claude-fable-5`, `claude-fable-5-1`, `claude-mythos-5`, `claude-mythos-5-1`. + +### Variants and costs + +- Display names end in a `(N×)` list-price multiplier relative to Haiku: 1× haiku, + 3× sonnet, 5× opus, 10× fable, mythos and fast-mode opus. It is display only. +- Every model except Haiku has reasoning variants `low`, `medium`, `high`, `xhigh`, + `max`, picked in opencode's model selector. A variant becomes + `CLAUDE_CODE_EFFORT_LEVEL` on the spawned CLI unless an agent effort wins. For direct + AI-SDK calls, `ClaudeCodeCallOptions.reasoningEffort` supports the same levels plus + `minimal` (mapped to `low`); it is not a provider startup option. +- The `-fast` ids are this plugin's own markers. They spawn the base model with + `--settings '{"fastMode":true}'` (Claude Code 2.1.220+). Fast mode fails soft: an + ineligible account runs at standard speed and the plugin logs a warning naming the + reason. Switch to a non-fast id rather than silently enabling paid usage credits. + Review eligibility/billing with the user; the enabled state needs live verification + on their account. CLI floors are gates, not proof of model access. +- `claude-mythos-5` and `claude-mythos-5-1` are limited availability (Project Glasswing). + Without access `claude --model` errors; use the corresponding `claude-fable-*`. +- Ordinary calls can pass through unregistered ids; availability and opencode model + registration still need checking. `forceModel`/`defaultSubagentModel` reject those ids. +- Registry costs are USD per million tokens, not subscription quota or a billing + guarantee. Fast entries have fast pricing; other entries use standard rates. There + is no above-200K tier in this registry; do not invent `cost.tiers` or + `cost.experimentalOver200K`. 4.5 models have 200K context/64K output, later registered + models have 1M/128K. Recheck vendor pricing/access separately when changing models. + +## Verify and diagnose + +Offline first: validate edited JSON/JSONC without starting opencode; inspect installed +package metadata. `claude --version` / `claude --help` on the trusted configured binary +and `opencode --version` do not request model inference. Do not invoke a model merely +to test configuration. A paid smoke test requires explicit approval and a bounded task. + +If diagnostic logging was approved, find the newest matching +`NOTICE: claude-code plugin ready` entry for the restarted process (INFO threshold +includes NOTICE). Do not paste the entire log or raw spawn arguments. + +Fields: `plugin` (version actually loaded), `opencode`, `cwd.resolved` and `cwd.source` +(`configured`, `process`, `captured`, `unresolved`), `providers`, `accounts`, +`proxyTools`, `mcpServers`, `interactiveTransport`, `planModeQuestion`, +`anthropicApiKeyInEnv`, `claudeCli.path` and `.version` +(`not detected` means the binary did not answer `--version`, which also disables +version-gated flags). Cwd is a startup fallback snapshot, not the per-session spawn +directory. MCP names are disk discovery, not proof of live connectivity. Interactive +status is a preference report, not proof that Bun PTY transport was used. Check a +relevant, redacted spawn/bridge entry for actual routing after an approved normal turn. + +Useful log lines to search for (redact payloads): `spawning new claude process`, +`bridged opencode skills into claude`, `interrupt sent for aborted turn`, `btw:`, +`rendering opencode-side tool result as text`, `proxy-mcp tool call received`, +`evicting idle claude process`, `fast mode` warnings. + +Version requirements: Claude Code CLI 2.1.142+ recommended (thinking summaries), +2.1.220+ for fast mode, 2.1.258+ for `/btw`. Check with `claude --version`. + +Only if a proxy security check is specifically requested: identify the exact local +proxy port first, not every opencode listener. An unauthenticated `initialize` with +the correct `127.0.0.1:` Host, no Origin and JSON Content-Type should get `401`. +`200` on a confirmed proxy endpoint is unsafe; restart/upgrade. Other status codes +alone do not prove it patched. Never call `tools/call` or obtain the bearer to probe. + +`/btw ` needs an existing headless Claude conversation and CLI 2.1.258+. +It asks through the side channel and keeps the answer in the conversation (inline +when possible); it is excluded from Claude's normal turn history.

The user's clean Omarchy installation reportedly works. On this Mac, global `~/.config/opencode/plugins/notify.ts` awaited `notifyQuestionIfNeeded` inside `tool.execute.before`; its backend awaited `alerter` exit, which defaults to waiting for dismissal indefinitely. A real question notification child started at exactly the failed question's timestamp and remained alive. opencode awaits before-hooks before calling the native question tool, so the request/form could not exist yet. Native providers still run global hooks and were not a plugin-free control. A no-inference test importing the real notification plugin failed with a pending simulated alerter and passed after the hook dispatched notification delivery without awaiting it, with rejection handling and deduplication preserved. Local regression test: `~/.config/opencode/tests/notify-question.test.ts`. For future failures, `GET /question` on the same server/workspace separates pre-tool blocking (absent request) from event/session/rendering issues (present request). #36604 remains open for detach/reattach; #36603 is closed unmerged, not a fix to wait on. Do not remove the user's no-question-tool preference without their approval. + +**Both round-trips are now verified, so every "blocked upstream, leave it off" line in the bullets below is history, not current advice.** After the restart, the maintainer authorized one native `question` call in the Mac TUI and answered it: the form rendered and the answer came back. The `"Question"` proxy was then verified end to end on plugin **0.18.0**, Claude Code **2.1.258**, opencode **1.18.29** through a headless `opencode serve` with a scratch config (`proxyTools: ["Question"]`, `permission.question: "allow"`, account `appical`, haiku): `plugin.log` shows `question proxy version gate {"opencodeHasQuestion":true,"kept":true}` then `proxy-mcp tool call received {"toolName":"question"}`, `GET /question` listed one pending request for the session, `POST /question/{id}/reply` with a random token completed the single `question` tool part, and Claude's final answer was that token, which it could only have obtained through the tool result. Probe script: `/var/folders/.../opencode/verify-provider-question.mjs` (scratch, not in the repo). The headless probes answered over HTTP, not by clicking, so the last join was closed separately: with `"Question"` added to the maintainer's own `proxyTools` and opencode relaunched, a two-question `mcp__opencode_proxy__question` call rendered as a real form in his TUI and both answers came back into the turn. Model to form to answer to model, in the actual terminal. `"Question"` stays out of `DEFAULT_PROXY_TOOL_NAMES` anyway: enabling it disables Claude's `AskUserQuestion` via `--disallowedTools`, and that swap is the operator's call, not a silent upgrade. `planModeQuestion` is still **unverified**, for a different reason than before: its delivery surface now works, but nobody has driven an actual `ExitPlanMode` approval through it. That is the test to run before promoting it. + - The `chat.params` hook tags opencode's active agent (`default`, `compaction`, `title`, etc.) into provider options. Write to `output.options` at the top level. opencode wraps that bag under the provider id later. Do not pre-nest under `output.options[providerID]`, or the model sees `providerOptions[id][id]`. - Reasoning effort is a spawn-time env var (`CLAUDE_CODE_EFFORT_LEVEL`, set in `claudeSpawnEnv` and the interactive session's env), not message text. Claude Code 2.1.x only recognises the `ultrathink` keyword, so the old per-level keywords were silently inert. Because the var is fixed per process, effort is part of the session key (`::effort=`); a respawn reads it back from `ActiveProcess.effort`. Compaction spawns never carry it. - **Per-agent model override (`src/agent-models.ts`) swaps the model NAME only, never the provider.** The account lives in the provider (`claude-code-` → `CLAUDE_CONFIG_DIR`) and in the `@` marker on the id, so the override reattaches that marker: `claude-fable-5-1@work` becomes `claude-opus-5@work`. Dropping the marker would silently move the work to the default account. Three guards keep it from surprising anyone, and none of them are optional: `defaultSubagentModel` is **unset by default**, so an upgrade changes no existing behaviour; only agents the plugin discovered (`config.agent` entries, markdown in `agents/`) are eligible, so opencode's built-ins stay out of the path or `explore` quietly becomes an Opus agent; and an unknown model id is refused rather than spawned. The effective model is part of the session key in BOTH `doGenerate` and `doStream`, otherwise an overridden subagent shares a `claude` process with its caller. The plugin defines **no agents of its own** on purpose: a provider plugin injecting opinionated agents (with their own permission blocks) into every user's `@` menu is not its job. diff --git a/README.md b/README.md index 3f7bd7b..18e6092 100644 --- a/README.md +++ b/README.md @@ -267,7 +267,7 @@ model: claude-code-appical/claude-opus-5@appical | `proxyTools` | string[] | `["Bash", "Edit", "Write", "WebFetch", "Task"]` | Claude built-in tools to route through opencode's executor + permission UI.

Tracked upstream as [anomalyco/opencode#36604](https://github.com/anomalyco/opencode/issues/36604) with fix [PR #36603](https://github.com/anomalyco/opencode/pull/36603) (unmerged).

With the hook made non-blocking, the form renders, and the full path through this plugin is verified: on plugin 0.18.0 / Claude Code 2.1.258 / opencode 1.18.29, Claude called `mcp__opencode_proxy__question`, the request appeared in `GET /question`, the reply completed the tool, and Claude's answer contained a token it could only have read from the tool result.

Keep the machinery (older/newer CLIs and the interactive transport may still offer it); just do not treat "the fallback did not render" as a plugin bug without re-running the two probes above. Evidence is model self-report plus the ToolSearch miss, both on haiku. - **Question proxy is blocked upstream — leave it off.** Verified 2026-07-26 on opencode 1.18.5: the proxy delivers correctly but opencode's own `question` TUI form never renders, so an enabled `Question` costs you the working `AskUserQuestion` fallback and gives a silent hang the operator can only escape by interrupting. Proof it is not ours: (a) `github-copilot/gpt-5.5`, a native provider with the plugin nowhere in the path, fails identically (`Tool execution aborted`, `metadata.interrupted: true`, ~27 s); (b) the `part` table shows every `question` call `completed` through 2026-04-25 and every one since 2026-05-18 aborted, i.e. an opencode regression somewhere in v1.14.24…v1.15.5 (note `The user dismissed this question` is a *different*, healthy error — it means the form rendered); (c) a `--pure` (no-plugin) headless `opencode serve` drives the whole server path green — tool blocks, `question.asked` publishes, `GET /question` lists it, `POST /question/{id}/reply` completes the tool with the answer and emits `question.replied`. So the server is fine and only the TUI render is broken. Upstream: anomalyco/opencode issue **#36604** (open) with fix **PR #36603** (`hydratePending()` at TUI bootstrap, open since 2026-07-13, unmerged). Re-test when that merges; until then do not promote `Question` toward the default list, and do not spend time debugging the proxy for this symptom. - Question proxy (absorbed from @jknlsn's `47501d0`, on master after 0.11.2) is the **opt-in alternative** to the deny/markdown path above, not a replacement for it. `"Question"` is deliberately NOT in `DEFAULT_PROXY_TOOL_NAMES` (`src/index.ts`) — enabling it disables Claude's built-in `AskUserQuestion` via `--disallowedTools` and swaps the unconditional stop-and-wait guarantee for an in-turn blocking form, which is a trade against issue #8. Keep it opt-in until it has Task's mileage; the comment above the constant records why, so do not "tidy" it into the default list. Three invariants: (1) `--disallowedTools` is computed from the **post-filter** proxy list (`enrichedProxy`), never `resolvedProxy` — `filterQuestionProxyByOpencodeSupport` drops the def on opencode builds without a `question` registry entry, and computing from the pre-filter list would disable `AskUserQuestion` while its replacement is absent, leaving the model with no question path at all. (2) `QUESTION_PROXY_HINT` must name the FULL `mcp__opencode_proxy__question`: haiku strips the MCP prefix and calls bare `question`, which opencode renders as `⚙ invalid` (same near-miss family as TaskCreate vs the task proxy). (3) `question` gets a 30-min default in `PROXY_PER_TOOL_DEFAULT_TIMEOUT_MS` because it blocks on a human reading a form; the flat 10-min ceiling rejected calls mid-answer. `fetchLiveToolInfo` does ONE `client.tool.list()` fetch feeding the task overlay, the question gate and the plan-mode gate — do not add a second fetch; `liveToolInfoOnce()` memoizes it per model instance for exactly that reason, and deliberately does **not** memoize an unresolved fetch (`resolved: false`) so a not-yet-ready opencode server cannot disable every overlay for the life of the process. The proxy defs stay spawn-time, so a reused process keeps its defs. Verified live on opencode 1.18.5 (registry has `question`); a build lacking it takes the fallback silently, which the `question proxy version gate` log line makes visible. Tests: `test-proxy-mcp.ts`, `test-cli-args.ts`, `test-subagent-hint.ts`, `test-ask-user-question.ts`. +- **`planModeQuestion` cannot fire on the headless transport, and `permissionMode: "plan"` is inert at the default `skipPermissions`. Both measured on CLI 2.1.258, 2026-09-06.** The bridge keys on an `ExitPlanMode` tool_use, and headless `--print` does not offer that tool: asked for its tool list in plan mode the model returned `Agent, Bash, Edit, ListAgents, Read, ReportFindings, ScheduleWakeup, Skill, ToolSearch, Workflow, Write`, said "I'm unable to exit plan mode from within the tool set available to me" when asked to work, and a full probe through the plugin (`planModeQuestion: true`, `skipPermissions: false`, opencode 1.18.29) logged no `ExitPlanMode` at all while the model asked for approval in prose and its blocked `write` produced no file. `--disallowedTools ExitPlanMode` still validates silently where a bogus name warns, so the name is known and this is headless dormancy, exactly the `AskUserQuestion` shape above — do not read "the bridge did not fire" as a plugin bug without re-running those probes. The separate trap: `buildCliArgs` pushes `--permission-mode` and `--dangerously-skip-permissions` independently, and the CLI lets the skip flag win, so `permissionMode: "plan"` with the default `skipPermissions: true` gives no plan mode whatsoever (verified: the file got written, unprompted; without the skip flag the same request was refused). Anyone testing plan mode must set `skipPermissions: false`. Probe script: `/var/folders/.../opencode/verify-plan-mode-question.mjs` (scratch, not in the repo). - Plan-mode approval bridge (`src/plan-mode-question.ts`, absorbed from @CollieIsCute's `8c5b583` with authorship preserved, issue #21) is **opt-in via `planModeQuestion` and off by default**, for the same reason the question proxy is: it delivers through opencode's `question` form, and that form does not render (see the gotcha above), so an enabled bridge turns a working text prompt into a hang. Do not promote it to a default until #36603 merges and the round-trip is re-tested live. What it does when on: `ExitPlanMode` stops being rendered as `**Do you want to proceed with this plan?** (yes/no)` text and instead ends the turn on `tool-calls` with a synthetic `question` tool-call, then the operator's answer is turned back into a `tool_result` **for the original `ExitPlanMode` tool_use id** and sent as the entire next user message. That last part is the whole point of the port: Claude Code only leaves plan mode when it sees that `tool_result`, so a "yes" typed as ordinary prose never actually unlocks it. Invariants: (1) the gate is `isPlanModeQuestionActive` (config + live registry has `question` + not compaction) and it is resolved in the doStream/doGenerate **prologue**, not inside the stream body: the ExitPlanMode branches run in a synchronous line handler and a reused process never reaches the spawn block where the registry snapshot is otherwise taken. (2) Both transports have two ExitPlanMode sites each (partial-event `content_block_stop` and whole-`assistant`-message), so a change to one needs the same change to its twin; all four keep the legacy text path verbatim in the `else`. (3) `clearExitPlanModeQuestions(sk)` runs wherever `deleteClaudeSessionId`/`deleteActiveProcess` do, or a stale pending id outlives its session and the next answer is routed to a dead tool_use. (4) `finishReason` must be `tool-calls` (not the usual unconditional `stop`) when a question call was emitted, or opencode never runs the tool. Offline tests: `test-exit-plan-mode-question.ts`. The approval round-trip itself needs a live opencode session with `permissionMode: "plan"` and is **not verified**; it cannot be while the form is broken. - Compress proxy tool (`src/compression-store.ts` + the `compress` def in `proxy-mcp.ts`, reimplemented from @flupkede's `4ac319f`/`5b4ee5d` on their unmerged `feature/compress-tool` branch, credit theirs). **Opt-in via `proxyTools: [..., "Compress"]`**, deliberately absent from `DEFAULT_PROXY_TOOL_NAMES` — it throws away the model's working context, which is not something to enable behind someone's back. It is the only proxy tool opencode never sees: `createProxyMcpServer`'s third argument is an interceptor map, and an intercepted `tools/call` is answered in-process (no broker entry, no deadline, no permission prompt).

Both measured on CLI 2.1.258, 2026-09-06.** The bridge keys on an `ExitPlanMode` tool_use, and headless `--print` does not offer that tool: asked for its tool list in plan mode the model returned `Agent, Bash, Edit, ListAgents, Read, ReportFindings, ScheduleWakeup, Skill, ToolSearch, Workflow, Write`, said "I'm unable to exit plan mode from within the tool set available to me" when asked to work, and a full probe through the plugin (`planModeQuestion: true`, `skipPermissions: false`, opencode 1.18.29) logged no `ExitPlanMode` at all while the model asked for approval in prose and its blocked `write` produced no file. `--disallowedTools ExitPlanMode` still validates silently where a bogus name warns, so the name is known and this is headless dormancy, exactly the `AskUserQuestion` shape above — do not read "the bridge did not fire" as a plugin bug without re-running those probes. **The separate trap is now fixed: `buildCliArgs` drops `--dangerously-skip-permissions` when `permissionMode` is `"plan"`.** It used to push both independently and the CLI lets the skip flag win, so `permissionMode: "plan"` at the default `skipPermissions: true` gave no plan mode whatsoever: verified by writing a file, unprompted, in a plan-mode run, where the same request without the skip flag was refused. Plan mode is a capability restriction rather than a prompt policy, so it wins; every other mode governs prompting, which is exactly what the skip flag is for, and still passes both. Live-verified after the fix through a full plugin probe at default settings: `--permission-mode plan` present, skip flag absent, requested file never created. Do not "restore symmetry" by making the flag unconditional again. The honest remainder, which `warnIfPlanModeCannotExit` in `index.ts` states once per process at WARN: nothing releases plan mode mid-session, so an enforced plan mode is a one-way door out of which the only exit is editing config and restarting opencode. The CLI does still write its own plan markdown under `~/.claude*/plans/`, which is its feature and outside the workspace. Probe scripts: `/var/folders/.../opencode/verify-plan-mode-question.mjs` and `verify-plan-enforced.mjs` (scratch, not in the repo). Tests: `test-cli-args.ts`. - Plan-mode approval bridge (`src/plan-mode-question.ts`, absorbed from @CollieIsCute's `8c5b583` with authorship preserved, issue #21) is **opt-in via `planModeQuestion` and off by default**, for the same reason the question proxy is: it delivers through opencode's `question` form, and that form does not render (see the gotcha above), so an enabled bridge turns a working text prompt into a hang. Do not promote it to a default until #36603 merges and the round-trip is re-tested live. What it does when on: `ExitPlanMode` stops being rendered as `**Do you want to proceed with this plan?** (yes/no)` text and instead ends the turn on `tool-calls` with a synthetic `question` tool-call, then the operator's answer is turned back into a `tool_result` **for the original `ExitPlanMode` tool_use id** and sent as the entire next user message. That last part is the whole point of the port: Claude Code only leaves plan mode when it sees that `tool_result`, so a "yes" typed as ordinary prose never actually unlocks it. Invariants: (1) the gate is `isPlanModeQuestionActive` (config + live registry has `question` + not compaction) and it is resolved in the doStream/doGenerate **prologue**, not inside the stream body: the ExitPlanMode branches run in a synchronous line handler and a reused process never reaches the spawn block where the registry snapshot is otherwise taken. (2) Both transports have two ExitPlanMode sites each (partial-event `content_block_stop` and whole-`assistant`-message), so a change to one needs the same change to its twin; all four keep the legacy text path verbatim in the `else`. (3) `clearExitPlanModeQuestions(sk)` runs wherever `deleteClaudeSessionId`/`deleteActiveProcess` do, or a stale pending id outlives its session and the next answer is routed to a dead tool_use. (4) `finishReason` must be `tool-calls` (not the usual unconditional `stop`) when a question call was emitted, or opencode never runs the tool. Offline tests: `test-exit-plan-mode-question.ts`. The approval round-trip itself needs a live opencode session with `permissionMode: "plan"` and is **not verified**; it cannot be while the form is broken. - Compress proxy tool (`src/compression-store.ts` + the `compress` def in `proxy-mcp.ts`, reimplemented from @flupkede's `4ac319f`/`5b4ee5d` on their unmerged `feature/compress-tool` branch, credit theirs). **Opt-in via `proxyTools: [..., "Compress"]`**, deliberately absent from `DEFAULT_PROXY_TOOL_NAMES` — it throws away the model's working context, which is not something to enable behind someone's back. It is the only proxy tool opencode never sees: `createProxyMcpServer`'s third argument is an interceptor map, and an intercepted `tools/call` is answered in-process (no broker entry, no deadline, no permission prompt).

A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id. Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's.

The blend is what opencode actually accepts from the `provider.models()` hook, confirmed empirically: models resolve and sessions run on 1.18.29 (live probes, 2026-09-06). Non-load-bearing but worth knowing: v2 documenting 300000 ms as the ambient timeout default is consistent with the 300 s proxy wall, though that wall is in the Claude CLI's MCP client, not opencode's fetch, so it is corroboration and not proof. +- Earlier audit, opencode v1.18.18 (2026-08-20, by diffing the published packages: `@opencode-ai/plugin` 1.18.5 vs 1.18.18 is byte-identical apart from `package.json`, and the only `@opencode-ai/sdk` type change is `capabilities.interleaved` widening — `reasoning_details` became `reasoning_text` and bare strings/booleans are accepted. `src/opencode-types.ts` was updated to match; we pass `interleaved: false`, so nothing else moved.

Bounded at 8 attempts either way, so the pre-fix worst case was an inflated and corrupted summary, not a hang. Found by a subagent review of the truncation change, not by the test suite, which had no compaction case at all. +- **opencode's `tool.definition`, `experimental.session.compacting` and `experimental.compaction.autocontinue` hooks were evaluated on 1.18.29 and deliberately NOT adopted** (issue #24). `tool.definition` fires only inside opencode's own `ToolRegistry.tools`, over built-ins plus filesystem/plugin-declared tools; **MCP tools are not in that registry**, and the MCP assembly path triggers only `tool.execute.before`/`after`. So it cannot reach the proxy defs this plugin serves to the Claude CLI, and it could not do the job anyway: opencode appends `describeTask`'s agent list *after* the hook returns, which is the exact ordering `overlayTaskProxyDescription` exists to control against Claude Code's description truncation. Its input is `{toolID}` alone, with no session/provider scope, so any edit would reshape tools for every provider in the user's opencode. The compaction hooks are a prompt-authoring hook and a veto on opencode's post-compaction synthetic turn; neither is registered here, so they cannot interact with this plugin's auto-continue, and they operate on a different boundary regardless (an opencode turn versus a CLI turn inside one opencode turn). `experimental.session.compacting` would also be strictly worse for detection than `opencodeAgent === "compaction"`, which is available synchronously per call and drives the model override, effort exemption, session key and lean spawn. +- **v2 plugin API: do not migrate, and the reload that exists is not the one we want** (issue #24, checked on 1.18.29). `Reload` is `{ reload: () => Promise }` (`dist/v2/promise/registration.d.ts`), and `catalog`, `agent`, `command`, `integration`, `reference` and `skill` carry it while **`aisdk` does not** (`dist/v2/promise/context.d.ts`). So model *metadata* can be re-transformed at runtime through `CatalogHooks = Hooks<{transform: CatalogDraft}>`, but the model implementation path cannot. That does not touch this plugin's actual pain point: provider options are captured at `createClaudeCode()` and baked into each `ClaudeCodeLanguageModel`, and `catalog.reload()` re-runs a catalog transform rather than re-reading `provider.claude-code.options`. The restart requirement is opencode's config loading, not the plugin API. Even the metadata win is nil here, since `src/models.ts` is a static registry that only changes on package upgrade, which requires a restart anyway. v1 is **not deprecated**: all five `@deprecated` markers in `dist/index.d.ts` are unrelated (auth-prompt `condition` → `when`, and the `AuthOuathResult` typo alias). ## Tests To Touch When Editing diff --git a/src/claude-code-language-model.ts b/src/claude-code-language-model.ts index 6dc7537..a2098a2 100644 --- a/src/claude-code-language-model.ts +++ b/src/claude-code-language-model.ts @@ -291,6 +291,23 @@ interface AutoContinueSnapshot { now?: number } +/** + * A compaction turn must never be nudged to continue. `AUTO_CONTINUE_PROMPT` + * says "Do not summarize; keep working", the exact inverse of what `/compact` + * is for, and continuation reopens the same stream rather than closing it, so + * the non-summary text would land inside what opencode stores as the session + * summary.

Tests: `test-auto-continue.ts` (five cases, all failing with the branch stubbed out). - **A compaction turn must never be nudged, and truncation-continue is what made that reachable.** `AUTO_CONTINUE_PROMPT` says "Do not summarize; keep working", the exact inverse of a `/compact` turn's job, and continuation reopens the same stream instead of closing it, so the non-summary text would be appended to what opencode stores as the session summary. `doStream` builds `autoContinueState` inline and passed `self.config.autoContinueIncompleteTurns` straight through with no `compactionMode` term, which was harmless only while every `stop_reason` returned `continue:false`. `autoContinueEnabledFor(compactionMode, configured)` now gates it, exported purely so the wiring is testable rather than only the pure decision function. Bounded at 8 attempts either way, so the pre-fix worst case was an inflated and corrupted summary, not a hang. Found by a subagent review of the truncation change, not by the test suite, which had no compaction case at all. - **opencode's `tool.definition`, `experimental.session.compacting` and `experimental.compaction.autocontinue` hooks were evaluated on 1.18.29 and deliberately NOT adopted** (issue #24). `tool.definition` fires only inside opencode's own `ToolRegistry.tools`, over built-ins plus filesystem/plugin-declared tools; **MCP tools are not in that registry**, and the MCP assembly path triggers only `tool.execute.before`/`after`. So it cannot reach the proxy defs this plugin serves to the Claude CLI, and it could not do the job anyway: opencode appends `describeTask`'s agent list *after* the hook returns, which is the exact ordering `overlayTaskProxyDescription` exists to control against Claude Code's description truncation. Its input is `{toolID}` alone, with no session/provider scope, so any edit would reshape tools for every provider in the user's opencode. The compaction hooks are a prompt-authoring hook and a veto on opencode's post-compaction synthetic turn; neither is registered here, so they cannot interact with this plugin's auto-continue, and they operate on a different boundary regardless (an opencode turn versus a CLI turn inside one opencode turn). `experimental.session.compacting` would also be strictly worse for detection than `opencodeAgent === "compaction"`, which is available synchronously per call and drives the model override, effort exemption, session key and lean spawn. -- **v2 plugin API: do not migrate, and the reload that exists is not the one we want** (issue #24, checked on 1.18.29). `Reload` is `{ reload: () => Promise }` (`dist/v2/promise/registration.d.ts`), and `catalog`, `agent`, `command`, `integration`, `reference` and `skill` carry it while **`aisdk` does not** (`dist/v2/promise/context.d.ts`).

The disk copy is now pushed only when the forwarded `extraSystemContent` does not already contain it; no match keeps the old behaviour, so the interactive transport (which forwards nothing) never loses it. Live-verified: one copy in a 63 KB appended prompt. Test in `test-compaction-model.ts`. - **Abort sends the CLI an `interrupt` control request** (`interruptTurn` in `session-manager.ts`, adapted from @broskees' `68ed142`, absorbed 2026-09-06). The CLI runs one turn per process and closing our stream told it nothing: an aborted turn ran to completion, billed, executed tools, and its late output plus stale `result` landed in the next turn (Joseph measured ~7,500 characters generated after abort). `noteTurnStarted` marks the process in flight at every stdin write that asks for work (fresh envelope, auto-continue, watchdog re-send), the terminal `result` line clears it inside the `rl` handler in `spawnClaudeProcess` (**not** a permanent `lineEmitter` listener: `listenerCount("line") === 0` is what routes unattended lines to the buffer and what `/btw` reads as busy, so a permanent listener would break both), the abort handler sends `{type:"control_request", request:{subtype:"interrupt"}}`, and a new turn that finds the previous one in flight interrupts it first with a 5 s cap, except tool-result turns where the CLI is legitimately parked in a proxy call. The interactive transport is never marked in flight (its stdin is a TUI). Live-verified on 2.1.258: abort mid-webfetch, `interrupt sent for aborted turn {idle:true}`, next turn clean in 8.5 s. Tests: `test-session-manager.ts`. - **`idleProcessTimeoutMs`** (cherry-picked from @bernardofortes' `a5f723a`, absorbed 2026-09-06, resolved by hand onto the current tree because his base predated the `--resume` rename and the respawn rework; the commit is still his). Off unless set. Timer armed in `completeResult` after `cleanupTurn`, cancelled by `getActiveProcess`/`setActiveProcess`/`detachActiveProcess`/spawn/exit, unref'd, and it deletes only if the same process object is still registered so a respawn cannot be killed by its predecessor's timer. Session id survives, so the next turn resumes. Tests: `test-session-manager.ts`. +- **The child's stdin needs its own `error` listener, and `proc.on("error")` is not it.** Every write that asks the CLI for work (fresh envelope, auto-continue, the watchdog re-send, `interruptTurn`) can land after the child died, and an `error` event on a stream with no listener throws inside **opencode's** process, not the child's. `spawnClaudeProcess` attaches a baseline `proc.stdin?.on("error", ...)` next to the process one; it logs at WARN with the errno and calls `settleTurn`, because no terminal `result` is ever coming for a write that never arrived. It deliberately does not end the turn: the child is gone, so the readline `close` follows and the turn's close handler reports it. Note EPIPE is delivered whenever libuv gets round to failing the queued write (measured: hundreds of ms, sometimes only once the child is killed), so the regression test emits the event directly; the contract under test is that something is listening. The interactive shim's `stdin` is a plain object with `write`/`end` and no emitter, so it cannot emit `error` and needs nothing. Test: `test-session-manager.ts`. +- **LRU eviction must never take a process that is mid-turn.** `evictIfNeeded` deleted the oldest of 16 outright, and the evicted turn's close handler then finished with reason `stop` and no error, so a user with many open chats saw an answer silently truncated. It now walks insertion order (which is LRU) for the first process with `turnInFlight !== true`, and when every process is busy it evicts **nothing** and warns, letting the map exceed the cap for a moment rather than killing live work. Do not "restore" the one-liner. Tests: `test-session-manager.ts` (both branches). +- **A child that closes without a `result` is an error, not a `stop`.** The doStream close handler finished the stream with `toFinishReason("stop")` and empty usage, so a crashed CLI read as a short but successful answer. It now emits an `error` part (consistent with the other error paths in that file) plus `finishReason: "error"`, built by `describeChildCrash(exitCode, signal, lastStderr)`. Three things hold it together: stderr was debug-only and clipped to 200 chars, so `retainStderr` keeps a 2 KB tail on the ActiveProcess (`lastStderr`, newest wins) as the only record of why; `proc.exitCode` is usually still `null` when stdout hits EOF, so the crash branch waits up to `CHILD_EXIT_STATUS_GRACE_MS` (250 ms) for the `exit` event rather than reporting a bare "closed its output"; and an abort is exempt (`autoContinueState.aborted`), since the operator asked for it and the CLI may exit before the interrupt's own result lands. The path where a `result` did arrive is untouched, and auto-continue is unaffected because it only runs from `completeResult` (`isError` already returns `{continue:false, reason:"error"}`). Tests: `test-respawn.ts` (fake CLI, crash and abort), `test-session-manager.ts` (retention cap, message shape). - **Skill bridge is opt-in** (`bridgeOpencodeSkills`, `src/skill-bridge.ts` written by @broskees in `68ed142`, absorbed 2026-09-06). opencode and Claude share the `/SKILL.md` format but not the roots, so opencode advertised skills the CLI's `Skill` tool could not find. The bridge stages a throwaway plugin dir (`skills-` under `pluginTmpDir`, linked, copy fallback for Windows) and passes `--plugin-dir`; the flag has no version marker so `detectCliSupportsFlag` probes `claude --help` (cached). **Deliberately off by default here**, unlike the fork: every bridged skill is also in the system prompt opencode forwards, so a big skill set doubles its cost per turn. Live-verified via `OPENCODE_CONFIG=` on a temp project: 4 skills bridged, `Skill` call rendered as opencode's `skill` tool, token returned. Only `~/.config/opencode/skills` and `.opencode/skills` are roots; `~/.agents/skills` is not opencode's, so those are not bridged. Wired into `doStream`'s spawn only. Tests: `test-skill-bridge.ts`. - **Two forks independently named the 5-minute proxy wall's timer**, which the 0.15.0 note above says not to claim without evidence: @broskees (`68ed142`) measured a hard 301 s and attributes it to undici's `headersTimeout` and `bodyTimeout` (300 s each) behind Node `fetch` in the CLI's MCP client; @HeikoAtGitHub (`42f426d`) measured 293 to 296 s plus a separate 300 s MCP-idle timer and, like 0.15.0, fixed it with SSE plus progress notifications. Treat 300 s undici as the working explanation; the 0.15.0 fix already covers it. - **Do not wait for `message_stop` to drain proxy calls.** @broskees' `a44a2dc`: draining only at that boundary deadlocked two ordinary Bash calls until their timeouts fired in succession, because the CLI blocks inside the MCP call before emitting it.

So it cannot reach the proxy defs this plugin serves to the Claude CLI, and it could not do the job anyway: opencode appends `describeTask`'s agent list *after* the hook returns, which is the exact ordering `overlayTaskProxyDescription` exists to control against Claude Code's description truncation. Its input is `{toolID}` alone, with no session/provider scope, so any edit would reshape tools for every provider in the user's opencode. The compaction hooks are a prompt-authoring hook and a veto on opencode's post-compaction synthetic turn; neither is registered here, so they cannot interact with this plugin's auto-continue, and they operate on a different boundary regardless (an opencode turn versus a CLI turn inside one opencode turn). `experimental.session.compacting` would also be strictly worse for detection than `opencodeAgent === "compaction"`, which is available synchronously per call and drives the model override, effort exemption, session key and lean spawn. - **v2 plugin API: do not migrate, and the reload that exists is not the one we want** (tracker is issue **#31**, checked on 1.18.29; #24 is closed and is not the tracker any more). `Reload` is `{ reload: () => Promise }` (`dist/v2/promise/registration.d.ts`), and `catalog`, `agent`, `command`, `integration`, `reference` and `skill` carry it while **`aisdk` does not** (`dist/v2/promise/context.d.ts`). So model *metadata* can be re-transformed at runtime through `CatalogHooks = Hooks<{transform: CatalogDraft}>`, but the model implementation path cannot. That does not touch this plugin's actual pain point: provider options are captured at `createClaudeCode()` and baked into each `ClaudeCodeLanguageModel`, and `catalog.reload()` re-runs a catalog transform rather than re-reading `provider.claude-code.options`. The restart requirement is opencode's config loading, not the plugin API. Even the metadata win is nil here, since `src/models.ts` is a static registry that only changes on package upgrade, which requires a restart anyway. v1 is **not deprecated**: all five `@deprecated` markers in `dist/index.d.ts` are unrelated (auth-prompt `condition` → `when`, and the `AuthOuathResult` typo alias). +- **Every `▌`-led text part the plugin writes must be registered in `PLUGIN_NOTE_MARKERS`** (`src/message-builder.ts`). The `/btw` aside started this, and there are now five more: the turn-stats footer (`TURN_STATS_MARKER`), the CLI self-compaction note, the rate-limit rejection line, the failed-result-subtype line, and the doctor report. None of them was ever Claude's output or ever in Claude's context, so a transcript rebuilt for a fresh CLI process must not hand any of them back as something the model said. The strip is **part-level and anchored at the start** for the same reason the aside's is: it matches `text.trimStart().startsWith(marker)` on a whole text part, so every one of these has to be enqueued as **its own** text part (`startTextBlock()` before it) rather than appended to the model's block. `filterSideQuestionHistory` also now drops the `/claude-code-doctor` user message and its reply, the same way it drops a `/btw` pair; it kept its `/btw`-era name because it is called from both transcript rebuild paths and renaming it would touch code two other lanes are in. Tests: `test-turn-stats.ts`, `test-doctor.ts`. +- **`turnStats` is off by default and must never fire on a compaction turn or a failed one** (`src/turn-stats.ts`, consumed in `doStream`'s `result` branch). A footer on a `/compact` turn would be appended to what opencode stores as the session summary, the same trap the auto-continue compaction fix documents above; a footer on a failed turn puts the bill where the error belongs. The numbers are the **turn totals** (`msg.usage` directly), deliberately not the last-iteration figures `toUsage` prefers: `toUsage` feeds opencode's context gauge, where summing iterations inflates the window and triggers premature compaction, while a cost line has to match `total_cost_usd`, which is cumulative. The same numbers go to `log.info` whatever the option is set to, because the footer is a display preference and the numbers are diagnostics. `permission_denials` reaches `providerMetadata` as **names and ids only**: a denial carries a `tool_input` on the wire that can be a whole file-write payload, which is why `ClaudeStreamMessage` deliberately does not declare that field. Tests: `test-turn-stats.ts`, `test-cli-events-stream.ts`. +- **The four CLI stream events in `src/cli-events.ts` were read out of the CLI's own zod schemas, not guessed** (2.1.263, `rg -a` over `~/.local/share/claude/versions/`; the binary is a Mach-O bundle and the schemas are in it as plain text). Confirmed shapes: `{type:"rate_limit_event", rate_limit_info:{status:"allowed"|"allowed_warning"|"rejected", rateLimitType?, resetsAt?, utilization?, isUsingOverage?, overageStatus?, overageResetsAt?, overageDisabledReason?}}`; `{type:"system", subtype:"compact_boundary", compact_metadata:{trigger:"manual"|"auto", pre_tokens, post_tokens?}}` (the stream schema says `compact_metadata`, the CLI's own transcript reader says `compactMetadata`, and both are parsed because both exist in the binary); `system`/`init` carrying `apiKeySource`, `permissionMode`, `model`, `tools[]`, `mcp_servers[{name,status}]`, `claude_code_version`; and `result` carrying `modelUsage` (per-model numeric counters) and `permission_denials`. Re-run those greps before changing a parser, and keep the parsing defensive anyway: a diagnostic that throws is worse than one that stays quiet. Every reporter dedupes **once per identity per process** (`_resetRateLimitReports` / `_resetSystemInitReports` are the test seams, same shape as `_resetFastModeWarnings`), because a rejected rate limit and a failed MCP server both repeat on every respawn. Levels follow the `src/logger.ts` rule: WARN for anything the user must act on, since only warn/error are alwaysStderr. +- **`apiKeySource` is the field that tells you pay-as-you-go billing is happening, and `process.env` is not.** `warnIfAnthropicApiKey` in `index.ts` sees only the env-var route; the CLI also takes a key from its own settings scopes (`user`, `project`, `org`) and from an `apiKeyHelper`, and `API_KEY_SOURCES` in `cli-events.ts` treats everything except `oauth` (the subscription) and `none` as a key in effect. That is also why the warning text branches on `ignoreAnthropicApiKey`: with the option already on, the env vars are stripped from the spawn, so a key still in effect did not come from the environment and recommending the option again would be wrong. +- **A failed CLI tool needs `isError: true` on the `tool-result` stream part, not just error text in the output.** Measured in opencode's own bundle: its AI SDK bridge does `if (V.isError) enqueue({type:"tool-error", ..., error: V.result}) else enqueue({type:"tool-result", ...})`, so without the flag a failed `Read` was forwarded as a successful tool result whose output happened to be an error message. AI SDK v3 has no `tool-error` stream part for a provider to emit directly (`LanguageModelV3ToolResult` with `isError` is the only route), so do not go looking for one. The source is `block.is_error` on the CLI's `tool_result` content block, which is why that field is now declared on `ClaudeStreamMessage.message.content[]`. +- **A `result` with a failing subtype finishes as `{unified:"error", raw:}`, and that is a deliberate widening of `toFinishReason`'s two-value vocabulary.** It used to be an unconditional `stop`, so opencode recorded `error_max_turns` as an ordinary reply. Checked against opencode's bundle before shipping: it validates the finish reason against the standard enum and falls back to `"unknown"`, so `"error"` is accepted and nothing branches on it destructively. This is the **with-result** case only; a CLI that dies without emitting a `result` at all is a different failure with its own handling. +- **`/claude-code-doctor` is answered by the plugin with no CLI inference** (`src/doctor.ts`, branch in `doStream` immediately above the `/btw` aside branch, registered by `registerDoctorCommand` in `index.ts`). Four things to keep true: (1) the command name has **no space** in it, because opencode invokes `/` and takes everything after the first space as `$ARGUMENTS`, so `claude-code doctor` would be the command `claude-code` with an argument; (2) it never overwrites a user-defined command of that name, same guard as `/btw`, and unlike `/btw` there is no hook to gate because the language model answers the message the template produces; (3) nothing secret may enter the report, meaning no proxy `authToken`, no `ANTHROPIC_API_KEY` value, no system prompt, and no pending call's `input` (a test asserts the report matches no credential-shaped string); (4) the loopback auth self-check posts **`initialize` only**, never `tools/call`, because a `tools/call` probe would execute something. `formatDoctorReport` is pure and `gatherDoctorReport` is the live half, which is what lets a test pin the whole report against a fixed object. It reads providers through `lastDiagnosticsProviders()` in `startup-diagnostics.ts`, recorded **before** that module's once-per-process log guard so an account expansion's second call wins. +- **`snapshotActiveProcesses` and `snapshotPendingProxyCalls` are read-only views added for the doctor.** Neither touches eviction, the child's `close`/`exit` handler, or stdin. `ActiveProcess.startedAt` is set in `spawnClaudeProcess`'s object literal purely so the report can show an age; `lastStderr` is read through an **optional property access and is never written here**, so the report works whether or not another change adds that field. + ## Tests To Touch When Editing - Version 0.15.0 proxy recovery: SSE `tools/call` replies send headers immediately plus 15-second comments, while preserving the existing authentication guards and per-tool deadlines.

Test: `test-session-manager.ts`. -- **LRU eviction must never take a process that is mid-turn.** `evictIfNeeded` deleted the oldest of 16 outright, and the evicted turn's close handler then finished with reason `stop` and no error, so a user with many open chats saw an answer silently truncated. It now walks insertion order (which is LRU) for the first process with `turnInFlight !== true`, and when every process is busy it evicts **nothing** and warns, letting the map exceed the cap for a moment rather than killing live work.

Do not "restore" the one-liner. The cap is **8** (was 16; the fork's figure, adopted in the fork-parity PR): the idle timer above does the real work and this is the backstop for a burst of chats inside one idle window. Tests: `test-session-manager.ts` (both branches). +- **A deleted opencode session releases everything at once, and host exit kills what is left.** The plugin's `event` hook (`index.ts`) acts on `session.deleted` only, reading the id from `properties.info.id` (`extractDeletedSessionId`), and calls `deleteActiveProcessesForSession`: every process whose `opencodeSessionID` tag or session-key affinity segment (`describeSessionKey(key).session`, which covers effort and compaction keys) matches is killed, its proxy server closed, and, unlike idle eviction, its Claude session id, plan-mode questions, todo ledger and compression summary are dropped, because a deleted session never resumes. The `"default"` affinity is the shared fallback bucket and is never matched. `ensureProcessExitCleanup` arms a single `process.once("exit")` that runs the synchronous `killAllActiveProcesses`, guarded so repeated plugin initialisation never stacks listeners. `detachActiveProcess` also rejects the broker's pending calls for the key once it closed the proxy server: nothing can answer them any more, and a `task` call has no deadline that would otherwise reap the entry. Tests: `test-session-manager.ts`, `test-process-lifecycle.ts`. - **A child that closes without a `result` is an error, not a `stop`.** The doStream close handler finished the stream with `toFinishReason("stop")` and empty usage, so a crashed CLI read as a short but successful answer. It now emits an `error` part (consistent with the other error paths in that file) plus `finishReason: "error"`, built by `describeChildCrash(exitCode, signal, lastStderr)`. Three things hold it together: stderr was debug-only and clipped to 200 chars, so `retainStderr` keeps a 2 KB tail on the ActiveProcess (`lastStderr`, newest wins) as the only record of why; `proc.exitCode` is usually still `null` when stdout hits EOF, so the crash branch waits up to `CHILD_EXIT_STATUS_GRACE_MS` (250 ms) for the `exit` event rather than reporting a bare "closed its output"; and an abort is exempt (`autoContinueState.aborted`), since the operator asked for it and the CLI may exit before the interrupt's own result lands. The path where a `result` did arrive is untouched, and auto-continue is unaffected because it only runs from `completeResult` (`isError` already returns `{continue:false, reason:"error"}`). Tests: `test-respawn.ts` (fake CLI, crash and abort), `test-session-manager.ts` (retention cap, message shape). -- **Skill bridge is opt-in** (`bridgeOpencodeSkills`, `src/skill-bridge.ts` written by @broskees in `68ed142`, absorbed 2026-09-06). opencode and Claude share the `/SKILL.md` format but not the roots, so opencode advertised skills the CLI's `Skill` tool could not find. The bridge stages a throwaway plugin dir (`skills-` under `pluginTmpDir`, linked, copy fallback for Windows) and passes `--plugin-dir`; the flag has no version marker so `detectCliSupportsFlag` probes `claude --help` (cached). **Deliberately off by default here**, unlike the fork: every bridged skill is also in the system prompt opencode forwards, so a big skill set doubles its cost per turn.

Tests: `test-skill-bridge.ts` (including the real argv of a spawned fake CLI on both headless paths), `test-claude-session-wrapper.ts`. - **Two forks independently named the 5-minute proxy wall's timer**, which the 0.15.0 note above says not to claim without evidence: @broskees (`68ed142`) measured a hard 301 s and attributes it to undici's `headersTimeout` and `bodyTimeout` (300 s each) behind Node `fetch` in the CLI's MCP client; @HeikoAtGitHub (`42f426d`) measured 293 to 296 s plus a separate 300 s MCP-idle timer and, like 0.15.0, fixed it with SSE plus progress notifications. Treat 300 s undici as the working explanation; the 0.15.0 fix already covers it. - **Do not wait for `message_stop` to drain proxy calls.** @broskees' `a44a2dc`: draining only at that boundary deadlocked two ordinary Bash calls until their timeouts fired in succession, because the CLI blocks inside the MCP call before emitting it. Our broker drains as calls arrive; keep it that way. - **Sweep the forks more often than once a quarter.** @galvani fixed the stale `toolCallMap` re-emission on 2026-05-25 (`2238ed0`) with the same log signature that took until 2026-09-06 to find here. The sweep is cheap: clone, add every fork as a remote, `git cherry origin/master ` per branch (patch-id equivalence, so absorbed cherry-picks do not show), read the bodies of what is left. - `signature_delta` is expected encrypted thinking metadata. Ignore it quietly; do not treat it as an error. - `WebSearch` with the default `"claude"` routing must NOT be forwarded as a tool-call part. opencode has no `WebSearch` registry entry, and (at least as of opencode v1.17.0) the AI SDK rejects unknown tool names with "Model tried to call unavailable tool" even when `providerExecuted: true` — users saw `⚙ invalid` rows on every CLI-internal web search (fixed after v0.8.0). `mapTool` returns `skip: true` for it, and both tool_use sites in `claude-code-language-model.ts` render the query as a `> **Web search:** …` text line instead (gated by `isWebSearchTool` + `isWebSearchHandledByCli` from `tool-mapping.ts`). Explicit opencode-tool routing (`webSearch: ""`) still forwards with `executed: false`. Tests in `test-tool-mapping.ts`. - `tool-input-delta` parts must only be forwarded for tool calls whose `tool-input-start` was actually emitted. opencode's AI SDK bridge (`packages/opencode/src/session/llm/ai-sdk.ts`) resolves delta/end names via `state.toolNames[event.id] ?? "unknown"`; a delta for an unseen id creates a permanently-pending part with `tool: "unknown"` that the TUI renders as `⚙ unknown`. Skipped tools (ToolSearch, TaskCreate/TaskUpdate, CLI-internal WebSearch, AskUserQuestion, ExitPlanMode, proxy tools) stream `input_json_delta` like any other tool_use, so the streaming site in `claude-code-language-model.ts` gates delta forwarding on a `started` flag set only when the input-start part went out (fixed after v0.8.1). Keep accumulating `inputJson` unconditionally — the skip-path text rendering (AskUserQuestion/ExitPlanMode/WebSearch) depends on it. -- Subagent dispatch must be steered at the tool *and* the prompt (absorbed from @jknlsn's `94980a6`, diagnosed on his fork 2026-07-04, re-confirmed live here 2026-07-26).

Since Task is proxied by default (v0.10.0) this is reachable without any config. Two spawn-time countermeasures, both required: `overlayTaskProxyDescription` in `proxy-mcp.ts` front-loads opencode's live agent-type list onto the `task` proxy def, and `SUBAGENT_DISPATCH_HINT` goes into the appended system prompt naming `mcp__opencode_proxy__task` as the only dispatch path. **Claude Code truncates long MCP tool descriptions, so position is load-bearing:** jknlsn's original pasted opencode's entire live description (2858 chars) in front of the static def, but opencode puts "Available agent types" at the *end* of it (char 2306), so the only part the model needed was exactly what got cut.

That overlap is the fingerprint: if the two child intervals ever stop overlapping, the fan-out has silently become serial again. - **`toolCallMap` is keyed by content-block index and MUST be deleted at `content_block_stop`.** Claude CLI restarts block indices at 0 on every assistant message, and one turn routinely holds several (tool_use -> tool_result -> answer, `numTurns: 2`). The entry was never deleted, unlike its neighbours `reasoningIds` and `textBlockIndices`, so message 2's answer-text block at index 0 hit message 1's stale tool_use entry and re-emitted a `tool-call` for an id opencode had already completed. That second part never receives a `tool-result`, so opencode aborts it at stream end with `Tool execution aborted` / `interrupted: true`, and opencode's `task` tool turns that abort into `Subagent failed (task_id: ...)` **even though the child answered correctly and finished with `stop`**. Diagnosed live 2026-09-06 on 0.15.0: three probes, deterministic — a subagent using any provider-executed tool failed, a subagent using no tools returned fine. The plugin log is the tell: two `tool call complete` lines with the same `id`, the second ~2 ms after the final text ends. This was NOT a 0.15.0 regression (aborted parts go back to at least 2026-08-16) and it silently produced the long-standing background noise of `⚙ aborted` rows in the main lane too; it only became a hard failure through the `task` tool. Do not "tidy" the delete away. Test: `test-tool-block-index.ts`, which fails with `got 2` without it. - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry. They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - proxy-mcp `tools/call` responses MUST be MCP results (`{ result: { content, isError } }`), never JSON-RPC error envelopes. Claude CLI validates every `tools/call` response against the MCP result schema and rejects JSON-RPC errors as a "malformed result that failed schema validation" (seen live 2026-07-04 on broker timeouts/orphans — fixed post-0.9.2). All three error paths in `src/proxy-mcp.ts` now return results with `isError: true`: unknown tool, `result.kind === "error"` (merged into the success path), and the outer `catch` when `requestMethod === "tools/call"`. Non-`tools/call` methods (initialize, tools/list) and unparseable requests still use JSON-RPC errors, which is spec-correct. `requestId`/`requestMethod` are hoisted above the try so the catch can echo them — do not regress to `id: null`. Tests: `test-proxy-mcp.ts`. - **The proxy MCP endpoint is authenticated.** It executes Bash/Edit/Write through opencode's executor, so before @willmcginnis's PR #28 (fixed in 0.13.2, disclosed as **GHSA-3mxm-w7gf-3c5x**, High/CVSS 7.5 `AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H`, affecting >= 0.1.3 < 0.13.2; a CVE was requested from GitHub's CNA on 2026-08-20 and was still unassigned at that point — check `gh api /repos/khalilgharbaoui/opencode-claude-code-plugin/security-advisories/GHSA-3mxm-w7gf-3c5x --jq .cve_id` and, once it lands, add it to the README security section and the v0.13.2 release notes) any local process could POST to the loopback port and get arbitrary command execution, and a web page could do it blind via a `text/plain` CORS simple request. `createProxyMcpServer` now mints a 256-bit bearer token per server, hands it to Claude in the `headers` block of the generated `--mcp-config` (that file is `0600`, which is now load-bearing), and rejects every request that fails one of four guards, in this order: `Host` must equal the bound `127.0.0.1:` authority (DNS rebinding), `Origin` must be absent, `Content-Type` must be `application/json` (forces a preflight that then fails, closing the simple-request hole), and the bearer token must match under `timingSafeEqual`. All four run **before** `readBody`, so an unauthenticated peer cannot stream a body into memory, and `reject()` sets `Connection: close` and destroys the socket so a slow unauthenticated body cannot hold `server.close()` open. Three consequences to remember: (1) `authToken` must never be logged or put in the URL — the log line in `reject()` deliberately reports only `hasAuthorization`, never values; (2) the Origin and Content-Type guards are **measured properties of the client we spawn**, not spec guarantees, so a future Claude CLI that starts sending an `Origin` would 403 every call — that is exactly why `reject()` logs a reason at NOTICE; (3) anything in-repo that drives the endpoint over HTTP has to authenticate, which is why `test-proxy-mcp.ts` has `authedPost` and `test-compress-tool.ts` threads `srv.authToken`. Live-verified end to end on **Claude Code 2.1.226** (2026-08-20): real CLI, real `--mcp-config`, proxy call received and answered. Do not "simplify" a guard without re-running that check; the unit tests cannot see a client-side header change. **Upgrading does not patch a running opencode**: the plugin is loaded once at process start, so every opencode left open from before the upgrade keeps serving an unauthenticated proxy port until it is restarted. Observed on the maintainer's own machine on 2026-08-20, where three sessions from Aug 5 and Aug 18 still answered `POST /mcp` with 200 and 145-byte MCP configs (no `headers` block) while the freshly started one answered 401 with a 272-byte config. That probe (`lsof -nP -iTCP -sTCP:LISTEN | grep opencode`, then an unauthenticated `initialize`, 401 = patched, 200 = stale) is the check to run after any security release, and it is in the README security section for users. -- Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. Tests: `test-proxy-mcp.ts`, `test-broker.ts`. -- Reused-process start watchdog. A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. +- **A proxied call ends on an event, not on a clock, and the tests pin each event.** This is the rationale behind the no-deadline `task` default, not a bigger timer: the plugin listens to the child process, the stdout stream and the control protocol, so it never has to infer from elapsed time that a subagent failed. The events, each with the regression that proves the call is released: opencode's result resolves it (`test-proxy-task.ts` "proxy MCP initializes, lists Task, and resolves it through the broker"); an abort rejects the turn's pending calls at once and interrupts the CLI, whether it lands before content (`test-proxy-task.ts` "immediate abort rejects a buffered Task call"), after content (`test-process-lifecycle.ts` "an abort after content…"), or while opencode is running the tool with the stream already closed on its boundary, where the signal fires on a closed stream and the handler acts only if no later turn has attached to the process (`test-process-lifecycle.ts` "an abort while opencode is running the tool…"; before the fork-parity PR that abort did nothing and the call waited for the next message); the next user message rejects the previous turn's calls as orphaned and the CLI's HTTP request gets the error result (`test-process-lifecycle.ts` "a task call the previous turn left pending…"); the child dying mid-turn ends the turn as an error and rejects its calls, and the child dying between turns rejects them from `spawnClaudeProcess`'s exit handler with no turn attached (`test-process-lifecycle.ts`, both `exit-*` modes; the between-turns case was a real gap before the fork-parity PR, covered only by the 60-min timer); a deleted session and host exit reject them through `detachActiveProcess` (`test-process-lifecycle.ts` event hook test, `test-session-manager.ts` `killAllActiveProcesses`); and a CLI that hung up on its own request keeps its entry for late-result recovery (`test-proxy-task.ts` recovery modes), as does a watchdog respawn (`test-respawn.ts`, completions carried to the replacement). **Every terminal-event test asserts both registries**, the proxy server's open HTTP requests (`ProxyMcpServer.pendingCallIds()`, read-only) and the broker's entries (`getPendingProxyCalls`), not merely that `kill()` ran or one promise rejected: with no deadline, an entry either side forgets to drop is permanent. What no event covers is a child that is alive and silent, which is what the start and inactivity watchdogs are for; they are unchanged and are not proxy deadlines. Keepalives are about the CLI's HTTP client, not the tool. Do not describe this change as "removing timeouts"; describe it as listening. +- Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` and `task_batch` **none**, `PROXY_NO_DEADLINE_MS` = 0; `question` 30 min) → `proxyToolTimeoutMs` config override (case-insensitive; positive replaces, `0` disables, negative/NaN ignored) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines (defaults with overrides applied) so the client never gives up before the broker, and it is `MAX_PROXY_TIMEOUT_MS` whenever any tool has no deadline, because the CLI rejects `timeout: 0` in the MCP config (fork measurement, `dd494a8`). **A deadline of 0 means no timer**: both the HTTP handler and the broker guard their `setTimeout` on `deadlineMs > 0` (the broker's `timer` is nullable), since `setTimeout(fn, 0)` would reject the call on the next tick. What releases an unlimited call instead is the existing lifecycle: the next user turn's orphan sweep, an abort before content, the child closing, the process being deleted (which now also rejects the broker's entries for the key, see the deleted-session gotcha), and the late-result recovery path for a client that hung up. That last one is why the fork's immediate client-disconnect cancellation (`CLIENT_GONE_MESSAGE`, `calls.emit("cancel")`) was **not** taken: it deleted the entry the recovery machinery needs to deliver a late `task` result as a continuation. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. `/claude-code-doctor` prints a 0 deadline as `none`. Tests: `test-proxy-mcp.ts`, `test-broker.ts`, `test-doctor.ts`. +- Reused-process start watchdog. A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The replacement inherits the old process's in-flight marker (`turnWasInFlight` read before the swap, `noteTurnStarted(replacement)` after; @broskees' `b719497`), and `deliverPendingCompletions` calls `noteTurnStarted` before its own write, so a recovered continuation is busy for abort, LRU eviction, the idle timer and the next turn's quiesce; before that handoff every one of them read the working replacement as idle. Still no permanent `lineEmitter` listener for it: `listenerCount("line") === 0` is load-bearing for the unattended buffer and `/btw`. The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id. Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's.

Measured live on opencode 1.18.29 (2026-09-06): a 35-character question was sent as 1,599 characters, and a bare `/btw` was never empty, so `SIDE_QUESTION_USAGE` was unreachable and the model answered "I don't see a question in your message" instead. The plan-mode reminder is the worst case (1,523 chars of "READ-ONLY phase / STRICTLY FORBIDDEN"), which is exactly the content most likely to steer an aside. Strip **wherever the block sits**, not by matching a whole part or anchoring at the end: a harness may append trailing metadata after the closing tag (opencode-dcp adds ``), and the first attempt at this fix used `endsWith("")`, passed its unit test, and still did nothing in production for exactly that reason. Only this parse strips reminders; normal turns must keep forwarding them, since they are opencode's instructions to the model. Live-verified after the fix by asking the aside its own word count: 17, matching the question alone. - **`/btw` is asked early and kept in the conversation (`src/btw-command.ts`, after 0.15.1).** Two designs were rejected live before this one. 0.15.x left the aside in the main lane, so a `/btw` typed mid-turn was "Queued" and then refused by the idle guard. The next attempt answered it in a child session with a toast, which the maintainer rejected on UX: the toast vanished before it could be read and the child session was not where anyone looked. What holds now rests on measured facts, re-check them before changing it: (1) opencode's TUI sends `session.command` immediately, busy or not (`packages/tui/src/component/prompt/index.tsx`), so `command.execute.before` fires at once; the resulting user message is what gets queued. (2) opencode's loop exits only when `lastAssistant.parentID === lastUser.id` (`session/prompt.ts` `runLoop`), so **any** message added to a busy session, `noReply` included, becomes the turn's next step, and that step is also the one carrying the results of the tools opencode just ran. Answering the aside there swallowed the turn's own continuation: measured live, turn 2's "finished" never appeared. (3) Claude Code answers `side_question` while the main loop is blocked (2.1.258: 2.3 s into a 35 s held tool call). So the hook finds the process by opencode session id (`findActiveProcessBySessionId`, fed by the `opencodeSessionID`/`asideTransport` tags doStream writes on every non-compaction turn), sends the `side_question` **immediately**, remembers the promise per session (`rememberSideQuestionAnswer`), toasts the answer when it arrives if the session was busy, and then **holds the command until `client.session.status()` reports the session idle** before returning, so opencode creates the `/btw` message only after the turn is completely over and runs it as a fresh turn. That turn hits the aside branch in `claude-code-language-model.ts`, which takes the remembered answer (`takeSideQuestionAnswer`) or asks the now idle process, and emits it as the assistant reply at 0 tokens; `filterSideQuestionHistory` keeps the pair out of Claude's prompt, and `collectSideQuestionHistory` feeds earlier pairs to follow-ups. Three traps: the remembered answer is matched by **prefix**, not equality, because opencode-dcp appends `` to the message text (an exact match missed live and the turn re-asked into the single-flight guard); busy must come from `session.status`, not the process's line-listener count, because the listener is detached while opencode runs a tool; and holding the route is fine because opencode already keeps the command route open for a queued prompt (34 s observed) and the TUI's call is fire-and-forget. The hook only intercepts when `registerSideQuestionCommand` returned true, so a user-defined `btw` command keeps opencode's normal behaviour. A no-process `/btw` answers with `BTW_NO_SESSION_MESSAGE` as text, not an error.

Earlier flat ceilings fired mid-subagent, Claude believed its dispatch had failed, and the eventual result was dropped because the parent turn had already ended on the timeout error; a 60-minute one did the same to anything longer. What the default gives up is only that nothing fires on the clock alone, so a chat parked in a `task` holds its `claude` worker until one of the events above happens. That is the operator's decision to make, so no timer makes it for them. + +The same events are also what let a legitimately long call complete, which is the second half of the story: the CLI's own HTTP client used to give up on a silent reply at about five minutes whatever the tool deadline said. Every held call therefore keeps its connection visibly alive. A client that advertises SSE gets immediate headers and a keepalive comment every 15 seconds (since 0.15.0); a client that only accepts JSON gets its headers immediately as well, as a chunked body carrying keepalive whitespace on the same cadence, which is still one valid JSON-RPC response when the result lands, on success and on error. Keepalives are about the connection, not the tool: they never extend or replace a deadline. Claude's MCP client timeout for the proxy server, written into the generated `--mcp-config`, is set to the largest effective deadline, and to the largest value the CLI accepts (Node's timer maximum, about 24.8 days) while any tool has no deadline, because the CLI rejects a `timeout` of `0` outright. + ### Per-tool proxy timeouts -Every proxied tool call has a deadline: if opencode hasn't resolved it (run the underlying tool and returned a result) within that many milliseconds, the call is rejected and Claude receives a timeout error.

Subagents routinely run 20–40 min, and a question can sit on a slow operator; under the old flat 10-minute ceiling the proxy fired mid-call, Claude believed its dispatch had failed, and the subagent's eventual result was dropped (the parent turn had already ended on the timeout error).

This prevents long unanswered HTTP requests from being abandoned before the configured tool deadline; JSON-only clients retain their existing response format.

Those exist because a process that is alive but wedged emits no event to listen to, and a proxy call is never what they are waiting on: a CLI parked inside a proxied tool is producing nothing on purpose, and both watchdogs know that.

"Billing change: June 15, 2026"): from 2026-06-15 Anthropic bills `claude -p` / Agent SDK usage (the plugin's default headless `--print` path) against a separate monthly Agent SDK credit on subscription plans (Pro $20 / Max 5x $100 / Max 20x $200), not normal plan limits; API-key auth is unaffected. Same day, `claude-sonnet-4-20250514` / `claude-opus-4-20250514` retire (not registered here, but pass-through overrides could hit them). Fable 5 is included free on plans only through 2026-06-22; after that it needs usage credits. Confirmed failure mechanism: the 400 `Third-party apps now draw from your extra usage...` corresponds to a `rate_limit_event` with `{rateLimitType:"five_hour", overageStatus:"rejected", overageDisabledReason:"org_level_disabled"}` under OAuth subscription auth, so org-level overage/extra usage being disabled can reject requests that do not fit the remaining rolling window. URL redaction was tested and reverted; the opencode repo URL is not the trigger. Interactive mitigation: live bisection showed this plugin's own CLI/AGENTS/continuation prompt succeeds, while opencode's forwarded system prompt payload can trip the usage gate on constrained subscription accounts. Interactive mode therefore intentionally omits the forwarded opencode system prompt by default. Real account-side fixes remain: enable overage/add extra usage, wait for the 5-hour window reset, switch account/org/plan, or use API-key auth. - **`AGENTS.md` must not reach the model twice** (`buildAppendedSystemPrompt`, cherry-picked from @HeikoAtGitHub's `25260a4`, absorbed 2026-09-06). opencode forwards `~/.config/opencode/AGENTS.md` inside its own system prompt under an `Instructions from:` header, and this plugin also read it from disk and appended it, so every turn paid for both copies (visible in any plugin-driven session's own system prompt). The disk copy is now pushed only when the forwarded `extraSystemContent` does not already contain it; no match keeps the old behaviour, so the interactive transport (which forwards nothing) never loses it. Live-verified: one copy in a 63 KB appended prompt. Test in `test-compaction-model.ts`. - **Abort sends the CLI an `interrupt` control request** (`interruptTurn` in `session-manager.ts`, adapted from @broskees' `68ed142`, absorbed 2026-09-06). The CLI runs one turn per process and closing our stream told it nothing: an aborted turn ran to completion, billed, executed tools, and its late output plus stale `result` landed in the next turn (Joseph measured ~7,500 characters generated after abort). `noteTurnStarted` marks the process in flight at every stdin write that asks for work (fresh envelope, auto-continue, watchdog re-send), the terminal `result` line clears it inside the `rl` handler in `spawnClaudeProcess` (**not** a permanent `lineEmitter` listener: `listenerCount("line") === 0` is what routes unattended lines to the buffer and what `/btw` reads as busy, so a permanent listener would break both), the abort handler sends `{type:"control_request", request:{subtype:"interrupt"}}`, and a new turn that finds the previous one in flight interrupts it first with a 5 s cap, except tool-result turns where the CLI is legitimately parked in a proxy call. The interactive transport is never marked in flight (its stdin is a TUI). Live-verified on 2.1.258: abort mid-webfetch, `interrupt sent for aborted turn {idle:true}`, next turn clean in 8.5 s. Tests: `test-session-manager.ts`. -- **`idleProcessTimeoutMs`** (cherry-picked from @bernardofortes' `a5f723a`, absorbed 2026-09-06, resolved by hand onto the current tree because his base predated the `--resume` rename and the respawn rework; the commit is still his). **On by default at 30 minutes** (`DEFAULT_IDLE_PROCESS_TIMEOUT_MS`, resolved by `resolveIdleProcessTimeoutMs` at the `completeResult` call site so an unset option means the default and an explicit `0` means off; @broskees' reaper figure, adopted in the fork-parity PR instead of his parallel sweep). Timer armed in `completeResult` after `cleanupTurn`, so the clock starts when a turn finishes, not at spawn; cancelled by `getActiveProcess`/`setActiveProcess`/`detachActiveProcess`/spawn/exit, unref'd, and it deletes only if the same process object is still registered so a respawn cannot be killed by its predecessor's timer. A process found `turnInFlight` when it fires (recovered continuation, auto-continue, late tool result) is re-armed, never killed, the same rule the LRU cap follows. Session id survives, so the next turn resumes. Tests: `test-session-manager.ts`, `test-process-lifecycle.ts` (armed by a real turn with no option set). +- **`idleProcessTimeoutMs`** (cherry-picked from @bernardofortes' `a5f723a`, absorbed 2026-09-06, resolved by hand onto the current tree because his base predated the `--resume` rename and the respawn rework; the commit is still his). **Off unless set** (`DEFAULT_IDLE_PROCESS_TIMEOUT_MS` is 0, resolved by `resolveIdleProcessTimeoutMs` at the `completeResult` call site so unset and `0` both arm nothing; @broskees' fork-parity PR #36 proposed 30 minutes by default and that was reverted at merge, since it changes when a resumed chat pays for a fresh `--resume` spawn and that is the user's call. The helper stays so a default can be revisited in one line). Timer armed in `completeResult` after `cleanupTurn`, so the clock starts when a turn finishes, not at spawn; cancelled by `getActiveProcess`/`setActiveProcess`/`detachActiveProcess`/spawn/exit, unref'd, and it deletes only if the same process object is still registered so a respawn cannot be killed by its predecessor's timer. A process found `turnInFlight` when it fires (recovered continuation, auto-continue, late tool result) is re-armed, never killed, the same rule the LRU cap follows. Session id survives, so the next turn resumes. Tests: `test-session-manager.ts`, `test-process-lifecycle.ts`. - **The child's stdin needs its own `error` listener, and `proc.on("error")` is not it.** Every write that asks the CLI for work (fresh envelope, auto-continue, the watchdog re-send, `interruptTurn`) can land after the child died, and an `error` event on a stream with no listener throws inside **opencode's** process, not the child's. `spawnClaudeProcess` attaches a baseline `proc.stdin?.on("error", ...)` next to the process one; it logs at WARN with the errno and calls `settleTurn`, because no terminal `result` is ever coming for a write that never arrived. It deliberately does not end the turn: the child is gone, so the readline `close` follows and the turn's close handler reports it. Note EPIPE is delivered whenever libuv gets round to failing the queued write (measured: hundreds of ms, sometimes only once the child is killed), so the regression test emits the event directly; the contract under test is that something is listening. The interactive shim's `stdin` is a plain object with `write`/`end` and no emitter, so it cannot emit `error` and needs nothing. Test: `test-session-manager.ts`. - **LRU eviction must never take a process that is mid-turn.** `evictIfNeeded` deleted the oldest of 16 outright, and the evicted turn's close handler then finished with reason `stop` and no error, so a user with many open chats saw an answer silently truncated. It now walks insertion order (which is LRU) for the first process with `turnInFlight !== true`, and when every process is busy it evicts **nothing** and warns, letting the map exceed the cap for a moment rather than killing live work. Do not "restore" the one-liner. The cap is **8** (was 16; the fork's figure, adopted in the fork-parity PR): the idle timer above does the real work and this is the backstop for a burst of chats inside one idle window. Tests: `test-session-manager.ts` (both branches). - **A deleted opencode session releases everything at once, and host exit kills what is left.** The plugin's `event` hook (`index.ts`) acts on `session.deleted` only, reading the id from `properties.info.id` (`extractDeletedSessionId`), and calls `deleteActiveProcessesForSession`: every process whose `opencodeSessionID` tag or session-key affinity segment (`describeSessionKey(key).session`, which covers effort and compaction keys) matches is killed, its proxy server closed, and, unlike idle eviction, its Claude session id, plan-mode questions, todo ledger and compression summary are dropped, because a deleted session never resumes. The `"default"` affinity is the shared fallback bucket and is never matched. `ensureProcessExitCleanup` arms a single `process.once("exit")` that runs the synchronous `killAllActiveProcesses`, guarded so repeated plugin initialisation never stacks listeners. `detachActiveProcess` also rejects the broker's pending calls for the key once it closed the proxy server: nothing can answer them any more, and a `task` call has no deadline that would otherwise reap the entry. Tests: `test-session-manager.ts`, `test-process-lifecycle.ts`. - **A child that closes without a `result` is an error, not a `stop`.** The doStream close handler finished the stream with `toFinishReason("stop")` and empty usage, so a crashed CLI read as a short but successful answer. It now emits an `error` part (consistent with the other error paths in that file) plus `finishReason: "error"`, built by `describeChildCrash(exitCode, signal, lastStderr)`. Three things hold it together: stderr was debug-only and clipped to 200 chars, so `retainStderr` keeps a 2 KB tail on the ActiveProcess (`lastStderr`, newest wins) as the only record of why; `proc.exitCode` is usually still `null` when stdout hits EOF, so the crash branch waits up to `CHILD_EXIT_STATUS_GRACE_MS` (250 ms) for the `exit` event rather than reporting a bare "closed its output"; and an abort is exempt (`autoContinueState.aborted`), since the operator asked for it and the CLI may exit before the interrupt's own result lands. The path where a `result` did arrive is untouched, and auto-continue is unaffected because it only runs from `completeResult` (`isError` already returns `{continue:false, reason:"error"}`). Tests: `test-respawn.ts` (fake CLI, crash and abort), `test-session-manager.ts` (retention cap, message shape). -- **Skill bridge is on by default** (`bridgeOpencodeSkills`, `src/skill-bridge.ts` written by @broskees in `68ed142`, absorbed 2026-09-06; default flipped to match the fork in the fork-parity PR). opencode and Claude share the `/SKILL.md` format but not the roots, so opencode advertised skills the CLI's `Skill` tool could not find.

A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The replacement inherits the old process's in-flight marker (`turnWasInFlight` read before the swap, `noteTurnStarted(replacement)` after; @broskees' `b719497`), and `deliverPendingCompletions` calls `noteTurnStarted` before its own write, so a recovered continuation is busy for abort, LRU eviction, the idle timer and the next turn's quiesce; before that handoff every one of them read the working replacement as idle. Still no permanent `lineEmitter` listener for it: `listenerCount("line") === 0` is load-bearing for the unattended buffer and `/btw`. The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly.

The blend is what opencode actually accepts from the `provider.models()` hook, confirmed empirically: models resolve and sessions run on 1.18.29 (live probes, 2026-09-06). Non-load-bearing but worth knowing: v2 documenting 300000 ms as the ambient timeout default is consistent with the 300 s proxy wall, though that wall is in the Claude CLI's MCP client, not opencode's fetch, so it is corroboration and not proof. - Earlier audit, opencode v1.18.18 (2026-08-20, by diffing the published packages: `@opencode-ai/plugin` 1.18.5 vs 1.18.18 is byte-identical apart from `package.json`, and the only `@opencode-ai/sdk` type change is `capabilities.interleaved` widening — `reasoning_details` became `reasoning_text` and bare strings/booleans are accepted. `src/opencode-types.ts` was updated to match; we pass `interleaved: false`, so nothing else moved.

Nothing we depend on broke, because the plugin does not import opencode's types at all — `src/opencode-types.ts` is a hand-written structural mirror, so drift is silent and has to be audited deliberately. Findings worth remembering: - The **v1 `Hooks` surface is unchanged** where we touch it: `config`, `provider: { id, models(provider, ctx) }`, `chat.params` (output still has `options: Record` at the top level, so the "do not pre-nest under providerID" gotcha still holds).

They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - proxy-mcp `tools/call` responses MUST be MCP results (`{ result: { content, isError } }`), never JSON-RPC error envelopes. Claude CLI validates every `tools/call` response against the MCP result schema and rejects JSON-RPC errors as a "malformed result that failed schema validation" (seen live 2026-07-04 on broker timeouts/orphans — fixed post-0.9.2). All three error paths in `src/proxy-mcp.ts` now return results with `isError: true`: unknown tool, `result.kind === "error"` (merged into the success path), and the outer `catch` when `requestMethod === "tools/call"`. Non-`tools/call` methods (initialize, tools/list) and unparseable requests still use JSON-RPC errors, which is spec-correct. `requestId`/`requestMethod` are hoisted above the try so the catch can echo them — do not regress to `id: null`. Tests: `test-proxy-mcp.ts`. - **The proxy MCP endpoint is authenticated.** It executes Bash/Edit/Write through opencode's executor, so before @willmcginnis's PR #28 (fixed in 0.13.2, disclosed as **GHSA-3mxm-w7gf-3c5x**, High/CVSS 7.5 `AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H`, affecting >= 0.1.3 < 0.13.2; a CVE was requested from GitHub's CNA on 2026-08-20 and was still unassigned at that point — check `gh api /repos/khalilgharbaoui/opencode-claude-code-plugin/security-advisories/GHSA-3mxm-w7gf-3c5x --jq .cve_id` and, once it lands, add it to the README security section and the v0.13.2 release notes) any local process could POST to the loopback port and get arbitrary command execution, and a web page could do it blind via a `text/plain` CORS simple request. `createProxyMcpServer` now mints a 256-bit bearer token per server, hands it to Claude in the `headers` block of the generated `--mcp-config` (that file is `0600`, which is now load-bearing), and rejects every request that fails one of four guards, in this order: `Host` must equal the bound `127.0.0.1:` authority (DNS rebinding), `Origin` must be absent, `Content-Type` must be `application/json` (forces a preflight that then fails, closing the simple-request hole), and the bearer token must match under `timingSafeEqual`. All four run **before** `readBody`, so an unauthenticated peer cannot stream a body into memory, and `reject()` sets `Connection: close` and destroys the socket so a slow unauthenticated body cannot hold `server.close()` open. Three consequences to remember: (1) `authToken` must never be logged or put in the URL — the log line in `reject()` deliberately reports only `hasAuthorization`, never values; (2) the Origin and Content-Type guards are **measured properties of the client we spawn**, not spec guarantees, so a future Claude CLI that starts sending an `Origin` would 403 every call — that is exactly why `reject()` logs a reason at NOTICE; (3) anything in-repo that drives the endpoint over HTTP has to authenticate, which is why `test-proxy-mcp.ts` has `authedPost` and `test-compress-tool.ts` threads `srv.authToken`. Live-verified end to end on **Claude Code 2.1.226** (2026-08-20): real CLI, real `--mcp-config`, proxy call received and answered. Do not "simplify" a guard without re-running that check; the unit tests cannot see a client-side header change. **Upgrading does not patch a running opencode**: the plugin is loaded once at process start, so every opencode left open from before the upgrade keeps serving an unauthenticated proxy port until it is restarted. Observed on the maintainer's own machine on 2026-08-20, where three sessions from Aug 5 and Aug 18 still answered `POST /mcp` with 200 and 145-byte MCP configs (no `headers` block) while the freshly started one answered 401 with a 272-byte config. That probe (`lsof -nP -iTCP -sTCP:LISTEN | grep opencode`, then an unauthenticated `initialize`, 401 = patched, 200 = stale) is the check to run after any security release, and it is in the README security section for users. +- **A call with no deadline reports itself, because nothing else will** (`PROXY_STALL_WARNING_MS` in `src/proxy-broker.ts`, 5 minutes, repeating). Removing the `task`/`task_batch` deadline was right on correctness and wrong on visibility: a wedged subagent went from "fails after 60 minutes" to "silent forever", with the operator as the only detector. The heartbeat restores the visibility half without restoring a killer: it **never ends a call**, it logs one line naming tool, call id, elapsed, `emitted`, `channelClosed` and what will end it. Four things hold it together. It is armed **only** when `deadlineMs === PROXY_NO_DEADLINE_MS`, since a deadline-bearing call already reports itself and a 5-minute build is not a stall. It is WARN for the same reason `reportFastModeState` is: only warn/error are alwaysStderr in `src/logger.ts`, so a NOTICE would be invisible outside debug mode and the line would exist for nobody. It is `unref`'d, so a heartbeat can never hold opencode's process open. And every removal site now goes through `clearPendingTimers(pending)` rather than clearing `timer` by hand, because a pending call holds **two** timers and an interval left running against a deleted entry is a leak that repeats forever. Deliberately not done: no warning from the proxy-mcp HTTP side, which holds its own timer for the same call and would double every line. Tests: `test-broker.ts` (repeat, both stop paths, the deadline-bearing case, the `0` seam), three of which fail with the arm condition stubbed to `false`. - **A proxied call ends on an event, not on a clock, and the tests pin each event.** This is the rationale behind the no-deadline `task` default, not a bigger timer: the plugin listens to the child process, the stdout stream and the control protocol, so it never has to infer from elapsed time that a subagent failed. The events, each with the regression that proves the call is released: opencode's result resolves it (`test-proxy-task.ts` "proxy MCP initializes, lists Task, and resolves it through the broker"); an abort rejects the turn's pending calls at once and interrupts the CLI, whether it lands before content (`test-proxy-task.ts` "immediate abort rejects a buffered Task call"), after content (`test-process-lifecycle.ts` "an abort after content…"), or while opencode is running the tool with the stream already closed on its boundary, where the signal fires on a closed stream and the handler acts only if no later turn has attached to the process (`test-process-lifecycle.ts` "an abort while opencode is running the tool…"; before the fork-parity PR that abort did nothing and the call waited for the next message); the next user message rejects the previous turn's calls as orphaned and the CLI's HTTP request gets the error result (`test-process-lifecycle.ts` "a task call the previous turn left pending…"); the child dying mid-turn ends the turn as an error and rejects its calls, and the child dying between turns rejects them from `spawnClaudeProcess`'s exit handler with no turn attached (`test-process-lifecycle.ts`, both `exit-*` modes; the between-turns case was a real gap before the fork-parity PR, covered only by the 60-min timer); a deleted session and host exit reject them through `detachActiveProcess` (`test-process-lifecycle.ts` event hook test, `test-session-manager.ts` `killAllActiveProcesses`); and a CLI that hung up on its own request keeps its entry for late-result recovery (`test-proxy-task.ts` recovery modes), as does a watchdog respawn (`test-respawn.ts`, completions carried to the replacement). **Every terminal-event test asserts both registries**, the proxy server's open HTTP requests (`ProxyMcpServer.pendingCallIds()`, read-only) and the broker's entries (`getPendingProxyCalls`), not merely that `kill()` ran or one promise rejected: with no deadline, an entry either side forgets to drop is permanent. What no event covers is a child that is alive and silent, which is what the start and inactivity watchdogs are for; they are unchanged and are not proxy deadlines. Keepalives are about the CLI's HTTP client, not the tool. Do not describe this change as "removing timeouts"; describe it as listening. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` and `task_batch` **none**, `PROXY_NO_DEADLINE_MS` = 0; `question` 30 min) → `proxyToolTimeoutMs` config override (case-insensitive; positive replaces, `0` disables, negative/NaN ignored) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines (defaults with overrides applied) so the client never gives up before the broker, and it is `MAX_PROXY_TIMEOUT_MS` whenever any tool has no deadline, because the CLI rejects `timeout: 0` in the MCP config (fork measurement, `dd494a8`). **A deadline of 0 means no timer**: both the HTTP handler and the broker guard their `setTimeout` on `deadlineMs > 0` (the broker's `timer` is nullable), since `setTimeout(fn, 0)` would reject the call on the next tick. What releases an unlimited call instead is the existing lifecycle: the next user turn's orphan sweep, an abort before content, the child closing, the process being deleted (which now also rejects the broker's entries for the key, see the deleted-session gotcha), and the late-result recovery path for a client that hung up. That last one is why the fork's immediate client-disconnect cancellation (`CLIENT_GONE_MESSAGE`, `calls.emit("cancel")`) was **not** taken: it deleted the entry the recovery machinery needs to deliver a late `task` result as a continuation. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. `/claude-code-doctor` prints a 0 deadline as `none`. Tests: `test-proxy-mcp.ts`, `test-broker.ts`, `test-doctor.ts`. - Reused-process start watchdog. A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The replacement inherits the old process's in-flight marker (`turnWasInFlight` read before the swap, `noteTurnStarted(replacement)` after; @broskees' `b719497`), and `deliverPendingCompletions` calls `noteTurnStarted` before its own write, so a recovered continuation is busy for abort, LRU eviction, the idle timer and the next turn's quiesce; before that handoff every one of them read the working replacement as idle. Still no permanent `lineEmitter` listener for it: `listenerCount("line") === 0` is load-bearing for the unattended buffer and `/btw`. The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly).

Earlier flat ceilings fired mid-subagent, Claude believed its dispatch had failed, and the eventual result was dropped because the parent turn had already ended on the timeout error; a 60-minute one did the same to anything longer. What the default gives up is only that nothing fires on the clock alone, so a chat parked in a `task` holds its `claude` worker until one of the events above happens.

Five minutes in, and every five minutes after, a call without a deadline logs a warning naming the tool, the call id, how long it has waited, and what will end it. It never ends the call, it only reports one, which is the whole point: the thing a deadline used to provide was visibility, not correctness, and visibility is what is kept. Calls that do have a deadline are not reported this way, because their deadline already does it. The line reaches your terminal (warnings always go to stderr), so a subagent that has genuinely wedged shows up on its own instead of waiting to be noticed. `/claude-code-doctor` lists the same calls on demand. + The same events are also what let a legitimately long call complete, which is the second half of the story: the CLI's own HTTP client used to give up on a silent reply at about five minutes whatever the tool deadline said. Every held call therefore keeps its connection visibly alive. A client that advertises SSE gets immediate headers and a keepalive comment every 15 seconds (since 0.15.0); a client that only accepts JSON gets its headers immediately as well, as a chunked body carrying keepalive whitespace on the same cadence, which is still one valid JSON-RPC response when the result lands, on success and on error. Keepalives are about the connection, not the tool: they never extend or replace a deadline. Claude's MCP client timeout for the proxy server, written into the generated `--mcp-config`, is set to the largest effective deadline, and to the largest value the CLI accepts (Node's timer maximum, about 24.8 days) while any tool has no deadline, because the CLI rejects a `timeout` of `0` outright. ### Per-tool proxy timeouts @@ -1065,7 +1067,7 @@ So autonomous compression is available, just not DCP's implementation of it.

It is skipped when `hasMatchedPendingResults` — evicting a child whose tool results are arriving this turn would deliver a `tool_result` to a process that never issued the `tool_use`. The mark is not consumed, so it fires on the next turn instead. 5. `CLAUDE_CLI_COMPRESS_NOTE` replaces `CLAUDE_CLI_CONTEXT_NOTE` only when `compress` is in the **post-overlay** proxy list (`enrichedProxy`), and it spells out the full `mcp__opencode_proxy__compress` for the same reason `QUESTION_PROXY_HINT` does. The default note still tells the model compress does not exist, which stays true for `doGenerate` (no proxy wiring) and the interactive transport (no proxy server). Tests: `test-compress-tool.ts`. The store/interceptor/prompt layers are covered offline; the end-to-end "model calls compress, next turn is fresh" round-trip is **not live-verified**. +- **Two different tools want the MCP name `compress`, and the precedence is deliberate** (`proxyOpencodeTools` + `resolveProxyOpencodeToolDefs` in `proxy-mcp.ts`). `resolvedProxyMcpTools` forwards an opencode tool only when its id matches an enabled MCP server (`` or `_`), so a tool another opencode **plugin declares directly** belongs to no server and `if (!matchedServer) continue` drops it. opencode-dcp's `compress` is exactly that, which is why dcp's "MAX CONTEXT LIMIT REACHED ... You MUST use the `compress` tool now" reminders were unobeyable under this provider: the tool is in `client.tool.list()` (confirmed on 1.18.31, alongside `question`, `task`, `skill`, `gemini_quota`, `quota_status`) and was simply never offered. `proxyOpencodeTools` is the explicit allowlist that forwards it, **empty by default**, and never automatic because a forwarded tool executes in opencode with the calling agent's permissions. The collision is resolved **twice, at two layers, and both are load-bearing**: (1) at def level, `taken` holds the names already claimed by `enrichedProxy` and the MCP defs, so a forwarded `compress` is dropped with a WARN rather than becoming a second def of the same name; (2) at interceptor level, `ensureProxyServer` takes an explicit `interceptCompress` flag instead of keying on `tools.some(t => t.name === "compress")`. Layer 2 is the one a def-level check cannot see and the one that actually bit: with **only** the forwarded def present there is nothing to collide with, and the old name-keyed condition would have answered opencode's tool with the plugin's in-process reset ("Summary stored...") while opencode never saw the call. The plugin's own tool wins when both are configured, because it is named explicitly in `proxyTools` and it manages the window that overflows here. `buildAppendedSystemPrompt` follows the same precedence and has a **third** note variant (`CLAUDE_CLI_OPENCODE_COMPRESS_NOTE`) that says the forwarded tool compresses **opencode's** transcript and not the Claude session: reusing the plugin's note would tell the model its context had been discarded when it has not. Live-verified 2026-09-19 on CLI 2.1.263 + opencode 1.18.31 with dcp loaded: `forwarding opencode tools through the proxy {"tools":["compress"]}`, proxy started with `tools: ["bash","compress"]`, `proxy-mcp tool call received {"toolName":"compress"}`, queued through the normal broker, and dcp really ran (`Compressed 3 messages into [Compressed conversation section]`). **The wrinkle to expect:** dcp's compress rewrites opencode's message history mid-turn, so opencode aborts the provider stream at that tool boundary (`abort between proxy tool boundaries; releasing pending calls`) and the result reaches the model on the next step through the issue #29 text path (`rendering opencode-side tool result as text`). The turn completes and nothing leaks, but do not read that abort as a regression. Collision verified live in the same session: WARN emitted, exactly one `compress` in the server's tool list, and the interceptor answered. Tests: `test-compress-tool.ts` (forwarding, unknown name, unreachable registry, both collision layers, note selection). + - **Probing any of this live needs a scratch `XDG_CONFIG_HOME`, not just `OPENCODE_CONFIG`.** opencode **merges** the `plugin` array with the user's global config, so a scratch config still loads the parent checkout's copy of this plugin and its provider registration can win. The symptom is silent and cost three paid runs: the option is visibly present in `GET /config` provider options, yet the model behaves like a build without it, because the language model came from the other copy. Assert `plugin ready` appears exactly **once** in `plugin.log`. Two smaller traps in the same family: a leftover `opencode.json` in a **parent directory** of the probe's cwd beats `OPENCODE_CONFIG`, so give each probe its own cwd; and an account provider's model id carries the marker (`claude-haiku-4-5@appical`), where a bare id 500s as an opaque `UnknownError`. + - **`stripContextReminders`** (`message-builder.ts`) is the other half, also **off by default**. dcp anchors its nudges into **message text** (`lib/messages/inject/utils.ts` appends to an existing text part or splices a synthetic one), not into the system prompt, so each is re-sent with every message that carries it; all of them are wrapped in ``. The strip runs once at the top of `getClaudeUserMessage`, which is why the fresh-session rebuild and the `/compact` transcript get it for free instead of each needing a flag. Three rules: it is matched **wherever the block sits**, because dcp appends `` after one and an end-anchored check would miss it (the same trap the `/btw` strip hit in production); emptied parts are kept as empty strings rather than dropped, since a nudge can be a message's only text part and removing it could leave a user message with no content at all; and it must never touch opencode's own `` blocks, which are opencode's instructions to the model. `shouldStripContextReminders` turns it off as soon as `compress` is named in either list, resolved from **config alone** so it is answerable before the spawn block (`userMsg` is built well ahead of it) and so a configured-but-unregistered name errs toward keeping the reminder. Tests: `test-get-claude-user-message.ts`. - `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`).

They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - proxy-mcp `tools/call` responses MUST be MCP results (`{ result: { content, isError } }`), never JSON-RPC error envelopes. Claude CLI validates every `tools/call` response against the MCP result schema and rejects JSON-RPC errors as a "malformed result that failed schema validation" (seen live 2026-07-04 on broker timeouts/orphans — fixed post-0.9.2). All three error paths in `src/proxy-mcp.ts` now return results with `isError: true`: unknown tool, `result.kind === "error"` (merged into the success path), and the outer `catch` when `requestMethod === "tools/call"`. Non-`tools/call` methods (initialize, tools/list) and unparseable requests still use JSON-RPC errors, which is spec-correct. `requestId`/`requestMethod` are hoisted above the try so the catch can echo them — do not regress to `id: null`. Tests: `test-proxy-mcp.ts`. - **The proxy MCP endpoint is authenticated.** It executes Bash/Edit/Write through opencode's executor, so before @willmcginnis's PR #28 (fixed in 0.13.2, disclosed as **GHSA-3mxm-w7gf-3c5x**, High/CVSS 7.5 `AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H`, affecting >= 0.1.3 < 0.13.2; a CVE was requested from GitHub's CNA on 2026-08-20 and was still unassigned at that point — check `gh api /repos/khalilgharbaoui/opencode-claude-code-plugin/security-advisories/GHSA-3mxm-w7gf-3c5x --jq .cve_id` and, once it lands, add it to the README security section and the v0.13.2 release notes) any local process could POST to the loopback port and get arbitrary command execution, and a web page could do it blind via a `text/plain` CORS simple request. `createProxyMcpServer` now mints a 256-bit bearer token per server, hands it to Claude in the `headers` block of the generated `--mcp-config` (that file is `0600`, which is now load-bearing), and rejects every request that fails one of four guards, in this order: `Host` must equal the bound `127.0.0.1:` authority (DNS rebinding), `Origin` must be absent, `Content-Type` must be `application/json` (forces a preflight that then fails, closing the simple-request hole), and the bearer token must match under `timingSafeEqual`. All four run **before** `readBody`, so an unauthenticated peer cannot stream a body into memory, and `reject()` sets `Connection: close` and destroys the socket so a slow unauthenticated body cannot hold `server.close()` open. Three consequences to remember: (1) `authToken` must never be logged or put in the URL — the log line in `reject()` deliberately reports only `hasAuthorization`, never values; (2) the Origin and Content-Type guards are **measured properties of the client we spawn**, not spec guarantees, so a future Claude CLI that starts sending an `Origin` would 403 every call — that is exactly why `reject()` logs a reason at NOTICE; (3) anything in-repo that drives the endpoint over HTTP has to authenticate, which is why `test-proxy-mcp.ts` has `authedPost` and `test-compress-tool.ts` threads `srv.authToken`. Live-verified end to end on **Claude Code 2.1.226** (2026-08-20): real CLI, real `--mcp-config`, proxy call received and answered. Do not "simplify" a guard without re-running that check; the unit tests cannot see a client-side header change. **Upgrading does not patch a running opencode**: the plugin is loaded once at process start, so every opencode left open from before the upgrade keeps serving an unauthenticated proxy port until it is restarted. Observed on the maintainer's own machine on 2026-08-20, where three sessions from Aug 5 and Aug 18 still answered `POST /mcp` with 200 and 145-byte MCP configs (no `headers` block) while the freshly started one answered 401 with a 272-byte config. That probe (`lsof -nP -iTCP -sTCP:LISTEN | grep opencode`, then an unauthenticated `initialize`, 401 = patched, 200 = stale) is the check to run after any security release, and it is in the README security section for users. +- **`proxyOpencodeMcpTools` is inert on opencode 1.18.31, and that is measured, not suspected.** It is on by default, so the natural reading is that MCP tools route through opencode's executor and permissions. They do not. `resolvedProxyMcpTools` filters `client.tool.list()` to ids matching an enabled MCP server (`` or `_`), and **that list contains no MCP-backed tools at all** any more. Probed 2026-09-19 against a live `opencode serve` on the maintainer's real config: `GET /experimental/tool` and `GET /experimental/tool/ids` both return 200 with only built-ins plus plugin-declared tools (`invalid, question, bash, read, glob, grep, edit, write, task, webfetch, todowrite, websearch, skill, apply_patch, gemini_quota, quota_status, compress`), while `GET /mcp` reports **five servers connected** (figma, furno-postgres, alwasiyyah-errors, obsidian, codebase-memory-mcp). Waiting 25 s changed nothing, so it is not a startup race. The match therefore finds nothing, `resolvedProxyMcpTools` returns null, and the option does nothing. **Nothing is broken by this**: `bridgeOpencodeMcp` hands the servers to Claude directly via `--mcp-config` and that works, which is why it went unnoticed. What is silently lost is only the *selective* routing, meaning those calls skip opencode's permission prompts and its tool-call rendering. Do not "fix" this by widening the prefix match; first find where MCP tools moved in opencode's registry, or establish that the route deliberately excludes them, because the answer decides whether the option should be repaired, redefined or documented as retired. Probe script: `/tmp/probe-toollist.mjs` (scratch, not in the repo). This is also why `proxyOpencodeTools` (PR #38) takes an explicit allowlist keyed on registry ids rather than extending the server-prefix rule. - **A call with no deadline reports itself, because nothing else will** (`PROXY_STALL_WARNING_MS` in `src/proxy-broker.ts`, 5 minutes, repeating). Removing the `task`/`task_batch` deadline was right on correctness and wrong on visibility: a wedged subagent went from "fails after 60 minutes" to "silent forever", with the operator as the only detector. The heartbeat restores the visibility half without restoring a killer: it **never ends a call**, it logs one line naming tool, call id, elapsed, `emitted`, `channelClosed` and what will end it. Four things hold it together. It is armed **only** when `deadlineMs === PROXY_NO_DEADLINE_MS`, since a deadline-bearing call already reports itself and a 5-minute build is not a stall. It is WARN for the same reason `reportFastModeState` is: only warn/error are alwaysStderr in `src/logger.ts`, so a NOTICE would be invisible outside debug mode and the line would exist for nobody. It is `unref`'d, so a heartbeat can never hold opencode's process open. And every removal site now goes through `clearPendingTimers(pending)` rather than clearing `timer` by hand, because a pending call holds **two** timers and an interval left running against a deleted entry is a leak that repeats forever. Deliberately not done: no warning from the proxy-mcp HTTP side, which holds its own timer for the same call and would double every line. Tests: `test-broker.ts` (repeat, both stop paths, the deadline-bearing case, the `0` seam), three of which fail with the arm condition stubbed to `false`. - **A proxied call ends on an event, not on a clock, and the tests pin each event.** This is the rationale behind the no-deadline `task` default, not a bigger timer: the plugin listens to the child process, the stdout stream and the control protocol, so it never has to infer from elapsed time that a subagent failed. The events, each with the regression that proves the call is released: opencode's result resolves it (`test-proxy-task.ts` "proxy MCP initializes, lists Task, and resolves it through the broker"); an abort rejects the turn's pending calls at once and interrupts the CLI, whether it lands before content (`test-proxy-task.ts` "immediate abort rejects a buffered Task call"), after content (`test-process-lifecycle.ts` "an abort after content…"), or while opencode is running the tool with the stream already closed on its boundary, where the signal fires on a closed stream and the handler acts only if no later turn has attached to the process (`test-process-lifecycle.ts` "an abort while opencode is running the tool…"; before the fork-parity PR that abort did nothing and the call waited for the next message); the next user message rejects the previous turn's calls as orphaned and the CLI's HTTP request gets the error result (`test-process-lifecycle.ts` "a task call the previous turn left pending…"); the child dying mid-turn ends the turn as an error and rejects its calls, and the child dying between turns rejects them from `spawnClaudeProcess`'s exit handler with no turn attached (`test-process-lifecycle.ts`, both `exit-*` modes; the between-turns case was a real gap before the fork-parity PR, covered only by the 60-min timer); a deleted session and host exit reject them through `detachActiveProcess` (`test-process-lifecycle.ts` event hook test, `test-session-manager.ts` `killAllActiveProcesses`); and a CLI that hung up on its own request keeps its entry for late-result recovery (`test-proxy-task.ts` recovery modes), as does a watchdog respawn (`test-respawn.ts`, completions carried to the replacement). **Every terminal-event test asserts both registries**, the proxy server's open HTTP requests (`ProxyMcpServer.pendingCallIds()`, read-only) and the broker's entries (`getPendingProxyCalls`), not merely that `kill()` ran or one promise rejected: with no deadline, an entry either side forgets to drop is permanent. What no event covers is a child that is alive and silent, which is what the start and inactivity watchdogs are for; they are unchanged and are not proxy deadlines. Keepalives are about the CLI's HTTP client, not the tool. Do not describe this change as "removing timeouts"; describe it as listening. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` and `task_batch` **none**, `PROXY_NO_DEADLINE_MS` = 0; `question` 30 min) → `proxyToolTimeoutMs` config override (case-insensitive; positive replaces, `0` disables, negative/NaN ignored) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines (defaults with overrides applied) so the client never gives up before the broker, and it is `MAX_PROXY_TIMEOUT_MS` whenever any tool has no deadline, because the CLI rejects `timeout: 0` in the MCP config (fork measurement, `dd494a8`). **A deadline of 0 means no timer**: both the HTTP handler and the broker guard their `setTimeout` on `deadlineMs > 0` (the broker's `timer` is nullable), since `setTimeout(fn, 0)` would reject the call on the next tick. What releases an unlimited call instead is the existing lifecycle: the next user turn's orphan sweep, an abort before content, the child closing, the process being deleted (which now also rejects the broker's entries for the key, see the deleted-session gotcha), and the late-result recovery path for a client that hung up. That last one is why the fork's immediate client-disconnect cancellation (`CLIENT_GONE_MESSAGE`, `calls.emit("cancel")`) was **not** taken: it deleted the entry the recovery machinery needs to deliver a late `task` result as a continuation. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. `/claude-code-doctor` prints a 0 deadline as `none`.

Four things to keep true: (1) the command name has **no space** in it, because opencode invokes `/` and takes everything after the first space as `$ARGUMENTS`, so `claude-code doctor` would be the command `claude-code` with an argument; (2) it never overwrites a user-defined command of that name, same guard as `/btw`, and unlike `/btw` there is no hook to gate because the language model answers the message the template produces; (3) nothing secret may enter the report, meaning no proxy `authToken`, no `ANTHROPIC_API_KEY` value, no system prompt, and no pending call's `input` (a test asserts the report matches no credential-shaped string); (4) the loopback auth self-check posts **`initialize` only**, never `tools/call`, because a `tools/call` probe would execute something. `formatDoctorReport` is pure and `gatherDoctorReport` is the live half, which is what lets a test pin the whole report against a fixed object.

A real Claude 2.1.258 call held for 390 seconds completed successfully; the previous single-shot response timed out before delivery. Do not claim a specific underlying timer without fresh evidence. A JSON-only client now gets the same liveness (`openJsonStream`, from @broskees' `68ed142`): headers flushed at once, chunked body, whitespace on the same `PROXY_KEEPALIVE_MS` cadence, envelope last, so the body is still one valid JSON-RPC response on success and on error. Only broker-backed calls stream; `initialize`, `tools/list`, unknown tools, bad batches and interceptors keep the single-shot `Content-Length` reply, and nothing is flushed before the four guards ran. `createProxyMcpServer`'s fourth argument (`keepaliveMs`) is a test seam. `ActiveProcess.pendingProxyCompletions` retains resolved results and shared channel references until continuation settles. Both live and buffered terminal boundaries must consume abandoned completions once, and respawn must preserve the map and original CLI args.

All four run **before** `readBody`, so an unauthenticated peer cannot stream a body into memory, and `reject()` sets `Connection: close` and destroys the socket so a slow unauthenticated body cannot hold `server.close()` open. Three consequences to remember: (1) `authToken` must never be logged or put in the URL — the log line in `reject()` deliberately reports only `hasAuthorization`, never values; (2) the Origin and Content-Type guards are **measured properties of the client we spawn**, not spec guarantees, so a future Claude CLI that starts sending an `Origin` would 403 every call — that is exactly why `reject()` logs a reason at NOTICE; (3) anything in-repo that drives the endpoint over HTTP has to authenticate, which is why `test-proxy-mcp.ts` has `authedPost` and `test-compress-tool.ts` threads `srv.authToken`. Live-verified end to end on **Claude Code 2.1.226** (2026-08-20): real CLI, real `--mcp-config`, proxy call received and answered. Do not "simplify" a guard without re-running that check; the unit tests cannot see a client-side header change. **Upgrading does not patch a running opencode**: the plugin is loaded once at process start, so every opencode left open from before the upgrade keeps serving an unauthenticated proxy port until it is restarted. Observed on the maintainer's own machine on 2026-08-20, where three sessions from Aug 5 and Aug 18 still answered `POST /mcp` with 200 and 145-byte MCP configs (no `headers` block) while the freshly started one answered 401 with a 272-byte config. That probe (`lsof -nP -iTCP -sTCP:LISTEN | grep opencode`, then an unauthenticated `initialize`, 401 = patched, 200 = stale) is the check to run after any security release, and it is in the README security section for users. - **`proxyOpencodeMcpTools` is inert on opencode 1.18.31, and that is measured, not suspected.** It is on by default, so the natural reading is that MCP tools route through opencode's executor and permissions. They do not. `resolvedProxyMcpTools` filters `client.tool.list()` to ids matching an enabled MCP server (`` or `_`), and **that list contains no MCP-backed tools at all** any more. Probed 2026-09-19 against a live `opencode serve` on the maintainer's real config: `GET /experimental/tool` and `GET /experimental/tool/ids` both return 200 with only built-ins plus plugin-declared tools (`invalid, question, bash, read, glob, grep, edit, write, task, webfetch, todowrite, websearch, skill, apply_patch, gemini_quota, quota_status, compress`), while `GET /mcp` reports **five servers connected** (figma, furno-postgres, alwasiyyah-errors, obsidian, codebase-memory-mcp). Waiting 25 s changed nothing, so it is not a startup race. The match therefore finds nothing, `resolvedProxyMcpTools` returns null, and the option does nothing. **Nothing is broken by this**: `bridgeOpencodeMcp` hands the servers to Claude directly via `--mcp-config` and that works, which is why it went unnoticed. What is silently lost is only the *selective* routing, meaning those calls skip opencode's permission prompts and its tool-call rendering. Do not "fix" this by widening the prefix match; first find where MCP tools moved in opencode's registry, or establish that the route deliberately excludes them, because the answer decides whether the option should be repaired, redefined or documented as retired. Probe script: `/tmp/probe-toollist.mjs` (scratch, not in the repo). This is also why `proxyOpencodeTools` (PR #38) takes an explicit allowlist keyed on registry ids rather than extending the server-prefix rule. -- **A call with no deadline reports itself, because nothing else will** (`PROXY_STALL_WARNING_MS` in `src/proxy-broker.ts`, 5 minutes, repeating).

Deliberately not done: no warning from the proxy-mcp HTTP side, which holds its own timer for the same call and would double every line. **The deadline-bearing half followed immediately, and the reason is worth keeping**: the original claim, that "a deadline already reports the call", was true only in the sense that it reports it *by killing it*, so the first signal is the failure. `PROXY_DEADLINE_WARNING_FRACTION` (0.6) fires one notice at 60% of the deadline with `remainingMs` and the `proxyToolTimeoutMs` hint, one-shot because the rejection speaks next, and `PROXY_DEADLINE_WARNING_MIN_MS` (60 s) skips short deadlines where the notice and the rejection would land together. Found by hitting it: two `write`/`bash` proxy calls were rejected at their 10-minute deadline while the work was actually succeeding, with no prior signal, and the session had to infer it from silence. Tests: five more in `test-broker.ts`; only the substantive one fails when the arm condition is stubbed, since three assert absence. Tests: `test-broker.ts` (repeat, both stop paths, the deadline-bearing case, the `0` seam), three of which fail with the arm condition stubbed to `false`. - **A proxied call ends on an event, not on a clock, and the tests pin each event.** This is the rationale behind the no-deadline `task` default, not a bigger timer: the plugin listens to the child process, the stdout stream and the control protocol, so it never has to infer from elapsed time that a subagent failed. The events, each with the regression that proves the call is released: opencode's result resolves it (`test-proxy-task.ts` "proxy MCP initializes, lists Task, and resolves it through the broker"); an abort rejects the turn's pending calls at once and interrupts the CLI, whether it lands before content (`test-proxy-task.ts` "immediate abort rejects a buffered Task call"), after content (`test-process-lifecycle.ts` "an abort after content…"), or while opencode is running the tool with the stream already closed on its boundary, where the signal fires on a closed stream and the handler acts only if no later turn has attached to the process (`test-process-lifecycle.ts` "an abort while opencode is running the tool…"; before the fork-parity PR that abort did nothing and the call waited for the next message); the next user message rejects the previous turn's calls as orphaned and the CLI's HTTP request gets the error result (`test-process-lifecycle.ts` "a task call the previous turn left pending…"); the child dying mid-turn ends the turn as an error and rejects its calls, and the child dying between turns rejects them from `spawnClaudeProcess`'s exit handler with no turn attached (`test-process-lifecycle.ts`, both `exit-*` modes; the between-turns case was a real gap before the fork-parity PR, covered only by the 60-min timer); a deleted session and host exit reject them through `detachActiveProcess` (`test-process-lifecycle.ts` event hook test, `test-session-manager.ts` `killAllActiveProcesses`); and a CLI that hung up on its own request keeps its entry for late-result recovery (`test-proxy-task.ts` recovery modes), as does a watchdog respawn (`test-respawn.ts`, completions carried to the replacement). **Every terminal-event test asserts both registries**, the proxy server's open HTTP requests (`ProxyMcpServer.pendingCallIds()`, read-only) and the broker's entries (`getPendingProxyCalls`), not merely that `kill()` ran or one promise rejected: with no deadline, an entry either side forgets to drop is permanent. What no event covers is a child that is alive and silent, which is what the start and inactivity watchdogs are for; they are unchanged and are not proxy deadlines. Keepalives are about the CLI's HTTP client, not the tool. Do not describe this change as "removing timeouts"; describe it as listening. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` and `task_batch` **none**, `PROXY_NO_DEADLINE_MS` = 0; `question` 30 min) → `proxyToolTimeoutMs` config override (case-insensitive; positive replaces, `0` disables, negative/NaN ignored) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines (defaults with overrides applied) so the client never gives up before the broker, and it is `MAX_PROXY_TIMEOUT_MS` whenever any tool has no deadline, because the CLI rejects `timeout: 0` in the MCP config (fork measurement, `dd494a8`). **A deadline of 0 means no timer**: both the HTTP handler and the broker guard their `setTimeout` on `deadlineMs > 0` (the broker's `timer` is nullable), since `setTimeout(fn, 0)` would reject the call on the next tick. What releases an unlimited call instead is the existing lifecycle: the next user turn's orphan sweep, an abort before content, the child closing, the process being deleted (which now also rejects the broker's entries for the key, see the deleted-session gotcha), and the late-result recovery path for a client that hung up. That last one is why the fork's immediate client-disconnect cancellation (`CLIENT_GONE_MESSAGE`, `calls.emit("cancel")`) was **not** taken: it deleted the entry the recovery machinery needs to deliver a late `task` result as a continuation. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. `/claude-code-doctor` prints a 0 deadline as `none`. Tests: `test-proxy-mcp.ts`, `test-broker.ts`, `test-doctor.ts`. - Reused-process start watchdog. A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The replacement inherits the old process's in-flight marker (`turnWasInFlight` read before the swap, `noteTurnStarted(replacement)` after; @broskees' `b719497`), and `deliverPendingCompletions` calls `noteTurnStarted` before its own write, so a recovered continuation is busy for abort, LRU eviction, the idle timer and the next turn's quiesce; before that handoff every one of them read the working replacement as idle. Still no permanent `lineEmitter` listener for it: `listenerCount("line") === 0` is load-bearing for the unattended buffer and `/btw`. The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly).

Calls that do have a deadline get one notice rather than a heartbeat, at 60% of the way to it, saying how long is left and which option would extend it. Before this, a deadline reported a call only by killing it: the first thing you heard was the failure, which is no use while there is still time to react. It is one line, never repeated, because the deadline itself is the next thing that will speak, and deadlines under a minute are skipped entirely since the notice and the rejection would arrive together. The line reaches your terminal (warnings always go to stderr), so a subagent that has genuinely wedged shows up on its own instead of waiting to be noticed. `/claude-code-doctor` lists the same calls on demand. The same events are also what let a legitimately long call complete, which is the second half of the story: the CLI's own HTTP client used to give up on a silent reply at about five minutes whatever the tool deadline said. Every held call therefore keeps its connection visibly alive. A client that advertises SSE gets immediate headers and a keepalive comment every 15 seconds (since 0.15.0); a client that only accepts JSON gets its headers immediately as well, as a chunked body carrying keepalive whitespace on the same cadence, which is still one valid JSON-RPC response when the result lands, on success and on error. Keepalives are about the connection, not the tool: they never extend or replace a deadline. Claude's MCP client timeout for the proxy server, written into the generated `--mcp-config`, is set to the largest effective deadline, and to the largest value the CLI accepts (Node's timer maximum, about 24.8 days) while any tool has no deadline, because the CLI rejects a `timeout` of `0` outright. diff --git a/skills/claude-code-plugin/SKILL.md b/skills/claude-code-plugin/SKILL.md index b38571d..b8eae3d 100644 --- a/skills/claude-code-plugin/SKILL.md +++ b/skills/claude-code-plugin/SKILL.md @@ -307,9 +307,13 @@ on a long call; they never extend a deadline).

Discovery read client.tool.list(), which enumerates opencode's tool registry: built-ins plus plugin-declared tools, never MCP ones. opencode merges MCP tools into the model's tool set after the registry is read, so the `tools` argument of doStream is the only place a provider plugin can see them. resolveMcpProxyToolDefs reads that instead; the server-name prefix match is unchanged and was always correct. Default goes true to false, which changes no behaviour because the option was inert. Leaving it on would have silently moved every user's MCP traffic off the direct bridge that carries it today. excludeServers now names only the servers a def was built for, so an enabled server with no def is not dropped from --mcp-config without being put on the proxy. --- AGENTS.md | 8 +- README.md | 4 +- skills/claude-code-plugin/SKILL.md | 4 +- src/claude-code-language-model.ts | 100 +++++++++++++---------- src/index.ts | 2 +- src/proxy-mcp.ts | 96 ++++++++++++++++++++++ src/types.ts | 30 ++++--- test-proxy-mcp.ts | 126 +++++++++++++++++++++++++++++ 8 files changed, 312 insertions(+), 58 deletions(-) diff --git a/AGENTS.md b/AGENTS.md index b803317..1dd1b25 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -78,7 +78,12 @@ This correction supersedes the historical claims below that native-provider fail - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry.

All four run **before** `readBody`, so an unauthenticated peer cannot stream a body into memory, and `reject()` sets `Connection: close` and destroys the socket so a slow unauthenticated body cannot hold `server.close()` open. Three consequences to remember: (1) `authToken` must never be logged or put in the URL — the log line in `reject()` deliberately reports only `hasAuthorization`, never values; (2) the Origin and Content-Type guards are **measured properties of the client we spawn**, not spec guarantees, so a future Claude CLI that starts sending an `Origin` would 403 every call — that is exactly why `reject()` logs a reason at NOTICE; (3) anything in-repo that drives the endpoint over HTTP has to authenticate, which is why `test-proxy-mcp.ts` has `authedPost` and `test-compress-tool.ts` threads `srv.authToken`. Live-verified end to end on **Claude Code 2.1.226** (2026-08-20): real CLI, real `--mcp-config`, proxy call received and answered. Do not "simplify" a guard without re-running that check; the unit tests cannot see a client-side header change. **Upgrading does not patch a running opencode**: the plugin is loaded once at process start, so every opencode left open from before the upgrade keeps serving an unauthenticated proxy port until it is restarted. Observed on the maintainer's own machine on 2026-08-20, where three sessions from Aug 5 and Aug 18 still answered `POST /mcp` with 200 and 145-byte MCP configs (no `headers` block) while the freshly started one answered 401 with a 272-byte config. That probe (`lsof -nP -iTCP -sTCP:LISTEN | grep opencode`, then an unauthenticated `initialize`, 401 = patched, 200 = stale) is the check to run after any security release, and it is in the README security section for users. -- **`proxyOpencodeMcpTools` is inert on opencode 1.18.31, and that is measured, not suspected.** It is on by default, so the natural reading is that MCP tools route through opencode's executor and permissions. They do not. `resolvedProxyMcpTools` filters `client.tool.list()` to ids matching an enabled MCP server (`` or `_`), and **that list contains no MCP-backed tools at all** any more. Probed 2026-09-19 against a live `opencode serve` on the maintainer's real config: `GET /experimental/tool` and `GET /experimental/tool/ids` both return 200 with only built-ins plus plugin-declared tools (`invalid, question, bash, read, glob, grep, edit, write, task, webfetch, todowrite, websearch, skill, apply_patch, gemini_quota, quota_status, compress`), while `GET /mcp` reports **five servers connected** (figma, furno-postgres, alwasiyyah-errors, obsidian, codebase-memory-mcp). Waiting 25 s changed nothing, so it is not a startup race. The match therefore finds nothing, `resolvedProxyMcpTools` returns null, and the option does nothing. **Nothing is broken by this**: `bridgeOpencodeMcp` hands the servers to Claude directly via `--mcp-config` and that works, which is why it went unnoticed. What is silently lost is only the *selective* routing, meaning those calls skip opencode's permission prompts and its tool-call rendering. Do not "fix" this by widening the prefix match; first find where MCP tools moved in opencode's registry, or establish that the route deliberately excludes them, because the answer decides whether the option should be repaired, redefined or documented as retired. Probe script: `/tmp/probe-toollist.mjs` (scratch, not in the repo). This is also why `proxyOpencodeTools` (PR #38) takes an explicit allowlist keyed on registry ids rather than extending the server-prefix rule. +- **`proxyOpencodeMcpTools` read the wrong registry, and the prefix rule was never the bug.** It defaulted to `true` and routed nothing, because `resolvedProxyMcpTools` discovered candidates from `client.tool.list()` (`GET /experimental/tool`), and **opencode's tool registry does not contain MCP tools**. Measured twice on 1.18.31, once on the maintainer's real config with five servers connected and once on a scratch config with one, both times returning only built-ins plus plugin-declared tools (`invalid, question, bash, read, glob, grep, edit, write, task, webfetch, todowrite, websearch, skill, apply_patch`, plus `gemini_quota, quota_status, compress` where those plugins are loaded); `GET /experimental/tool/ids` documents itself as "all tool IDs (including built-in and dynamically registered)" and is no better. Waiting 25 s changed nothing, so it is not a startup race, and no loose substring of a connected server name matched either, so it was never a naming-scheme problem. The full SDK route list in `dist/gen/sdk.gen.js` has exactly two tool routes and no other surface carries tool names, and neither the v1 `Hooks` surface nor the v2 `PluginContext` (`agent`, `aisdk`, `catalog`, `command`, `integration`, `plugin`, `reference`, `skill`) has an MCP-tool domain. + - **Where they actually are: the model tool set, which is downstream of the registry.** In opencode's own bundle the session assembles `o` from `ToolRegistry.tools` first, then adds the MCP resources tool, then does `for (let [k, W] of Object.entries(yield* d.tools())) { ... o[k] = b } return o`, where `d.tools()` is `MCP.tools()` and `k` is `MCP.toolName(server, tool)`. So MCP tools join the same dict the built-ins are in, after the registry has been read, which is why a registry query cannot see them and why `tool.definition` cannot either. That dict is what reaches the provider, so **the `tools` argument of `doStream` is the only place a provider plugin can discover them**. `resolveMcpProxyToolDefs` in `proxy-mcp.ts` now reads it. The `` / `_` prefix match is unchanged and was always correct: live names look like `codebase-memory-mcp_list_projects`, hyphens in the server name and all. + - **The default went `true` to `false`, and that changed no behaviour.** The option was inert, so leaving it on while repairing discovery would have silently moved every user's MCP traffic off the direct bridge that is carrying it today. Turning it on is now the operator's call, consistent with `proxyOpencodeTools`, the compress tool and the skill bridge. `excludeServers` also narrowed from "every enabled server" to only the servers a def was actually built for: it was safe while the resolution was always null, but excluding a server with no def would drop it from `--mcp-config` without putting it on the proxy, reachable by neither route. + - **Enabling it is not enough on its own, and this cost a probe to find.** Claude Code merges its *own* user-scope MCP config with the `--mcp-config` this plugin writes. With `codebase-memory-mcp` in both, excluding it from our config changed nothing: Claude called `mcp__codebase-memory-mcp__list_projects` through its own child, the log shows `mapping MCP tool` and `executed: true`, and the proxy was never touched. Adding `strictMcpConfig: true` fixed it. Both README and SKILL.md say to pair the two; a user reporting "I enabled it and nothing routes" is almost certainly hitting this. + - **Live-verified 2026-09-19** on opencode 1.18.31 + Claude Code 2.1.263, scratch `XDG_CONFIG_HOME` and scratch cwd (one `plugin ready`, providers `["claude-code"]`): `routing opencode MCP tools through the proxy` listed all 14 `codebase-memory-mcp_*` tools while `GET /experimental/tool/ids` on the same server listed none of them, `proxy-mcp server started` carried them as defs, `proxy-mcp tool call received {"toolName":"codebase-memory-mcp_list_projects"}` fired, and the stored transcript holds a `completed` tool part with 3521 characters of real output followed by the model's answer. One wrinkle to expect and not misread: opencode aborted the provider stream at that tool boundary (`abort between proxy tool boundaries`) and the result reached the model through the issue-#29 text path (`rendering opencode-side tool result as text`), the same shape AGENTS.md already records for dcp's `compress`. The turn completed and the tool part rendered correctly. Probe scripts were scratch under `/tmp/ocprobe`, not in the repo. + - This is still why `proxyOpencodeTools` (PR #38) takes an explicit allowlist keyed on registry ids rather than extending the server-prefix rule: a plugin-declared tool belongs to no MCP server, so no prefix rule can ever reach it. - **A call with no deadline reports itself, because nothing else will** (`PROXY_STALL_WARNING_MS` in `src/proxy-broker.ts`, 5 minutes, repeating). Removing the `task`/`task_batch` deadline was right on correctness and wrong on visibility: a wedged subagent went from "fails after 60 minutes" to "silent forever", with the operator as the only detector. The heartbeat restores the visibility half without restoring a killer: it **never ends a call**, it logs one line naming tool, call id, elapsed, `emitted`, `channelClosed` and what will end it. Four things hold it together. It is armed **only** when `deadlineMs === PROXY_NO_DEADLINE_MS`, since a deadline-bearing call already reports itself and a 5-minute build is not a stall. It is WARN for the same reason `reportFastModeState` is: only warn/error are alwaysStderr in `src/logger.ts`, so a NOTICE would be invisible outside debug mode and the line would exist for nobody. It is `unref`'d, so a heartbeat can never hold opencode's process open. And every removal site now goes through `clearPendingTimers(pending)` rather than clearing `timer` by hand, because a pending call holds **two** timers and an interval left running against a deleted entry is a leak that repeats forever. Deliberately not done: no warning from the proxy-mcp HTTP side, which holds its own timer for the same call and would double every line. **The deadline-bearing half followed immediately, and the reason is worth keeping**: the original claim, that "a deadline already reports the call", was true only in the sense that it reports it *by killing it*, so the first signal is the failure. `PROXY_DEADLINE_WARNING_FRACTION` (0.6) fires one notice at 60% of the deadline with `remainingMs` and the `proxyToolTimeoutMs` hint, one-shot because the rejection speaks next, and `PROXY_DEADLINE_WARNING_MIN_MS` (60 s) skips short deadlines where the notice and the rejection would land together. Found by hitting it: two `write`/`bash` proxy calls were rejected at their 10-minute deadline while the work was actually succeeding, with no prior signal, and the session had to infer it from silence. Tests: five more in `test-broker.ts`; only the substantive one fails when the arm condition is stubbed, since three assert absence. Tests: `test-broker.ts` (repeat, both stop paths, the deadline-bearing case, the `0` seam), three of which fail with the arm condition stubbed to `false`. - **A proxied call ends on an event, not on a clock, and the tests pin each event.** This is the rationale behind the no-deadline `task` default, not a bigger timer: the plugin listens to the child process, the stdout stream and the control protocol, so it never has to infer from elapsed time that a subagent failed. The events, each with the regression that proves the call is released: opencode's result resolves it (`test-proxy-task.ts` "proxy MCP initializes, lists Task, and resolves it through the broker"); an abort rejects the turn's pending calls at once and interrupts the CLI, whether it lands before content (`test-proxy-task.ts` "immediate abort rejects a buffered Task call"), after content (`test-process-lifecycle.ts` "an abort after content…"), or while opencode is running the tool with the stream already closed on its boundary, where the signal fires on a closed stream and the handler acts only if no later turn has attached to the process (`test-process-lifecycle.ts` "an abort while opencode is running the tool…"; before the fork-parity PR that abort did nothing and the call waited for the next message); the next user message rejects the previous turn's calls as orphaned and the CLI's HTTP request gets the error result (`test-process-lifecycle.ts` "a task call the previous turn left pending…"); the child dying mid-turn ends the turn as an error and rejects its calls, and the child dying between turns rejects them from `spawnClaudeProcess`'s exit handler with no turn attached (`test-process-lifecycle.ts`, both `exit-*` modes; the between-turns case was a real gap before the fork-parity PR, covered only by the 60-min timer); a deleted session and host exit reject them through `detachActiveProcess` (`test-process-lifecycle.ts` event hook test, `test-session-manager.ts` `killAllActiveProcesses`); and a CLI that hung up on its own request keeps its entry for late-result recovery (`test-proxy-task.ts` recovery modes), as does a watchdog respawn (`test-respawn.ts`, completions carried to the replacement). **Every terminal-event test asserts both registries**, the proxy server's open HTTP requests (`ProxyMcpServer.pendingCallIds()`, read-only) and the broker's entries (`getPendingProxyCalls`), not merely that `kill()` ran or one promise rejected: with no deadline, an entry either side forgets to drop is permanent. What no event covers is a child that is alive and silent, which is what the start and inactivity watchdogs are for; they are unchanged and are not proxy deadlines. Keepalives are about the CLI's HTTP client, not the tool. Do not describe this change as "removing timeouts"; describe it as listening. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` and `task_batch` **none**, `PROXY_NO_DEADLINE_MS` = 0; `question` 30 min) → `proxyToolTimeoutMs` config override (case-insensitive; positive replaces, `0` disables, negative/NaN ignored) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines (defaults with overrides applied) so the client never gives up before the broker, and it is `MAX_PROXY_TIMEOUT_MS` whenever any tool has no deadline, because the CLI rejects `timeout: 0` in the MCP config (fork measurement, `dd494a8`). **A deadline of 0 means no timer**: both the HTTP handler and the broker guard their `setTimeout` on `deadlineMs > 0` (the broker's `timer` is nullable), since `setTimeout(fn, 0)` would reject the call on the next tick. What releases an unlimited call instead is the existing lifecycle: the next user turn's orphan sweep, an abort before content, the child closing, the process being deleted (which now also rejects the broker's entries for the key, see the deleted-session gotcha), and the late-result recovery path for a client that hung up. That last one is why the fork's immediate client-disconnect cancellation (`CLIENT_GONE_MESSAGE`, `calls.emit("cancel")`) was **not** taken: it deleted the entry the recovery machinery needs to deliver a late `task` result as a continuation. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. `/claude-code-doctor` prints a 0 deadline as `none`.

The events, each with the regression that proves the call is released: opencode's result resolves it (`test-proxy-task.ts` "proxy MCP initializes, lists Task, and resolves it through the broker"); an abort rejects the turn's pending calls at once and interrupts the CLI, whether it lands before content (`test-proxy-task.ts` "immediate abort rejects a buffered Task call"), after content (`test-process-lifecycle.ts` "an abort after content…"), or while opencode is running the tool with the stream already closed on its boundary, where the signal fires on a closed stream and the handler acts only if no later turn has attached to the process (`test-process-lifecycle.ts` "an abort while opencode is running the tool…"; before the fork-parity PR that abort did nothing and the call waited for the next message); the next user message rejects the previous turn's calls as orphaned and the CLI's HTTP request gets the error result (`test-process-lifecycle.ts` "a task call the previous turn left pending…"); the child dying mid-turn ends the turn as an error and rejects its calls, and the child dying between turns rejects them from `spawnClaudeProcess`'s exit handler with no turn attached (`test-process-lifecycle.ts`, both `exit-*` modes; the between-turns case was a real gap before the fork-parity PR, covered only by the 60-min timer); a deleted session and host exit reject them through `detachActiveProcess` (`test-process-lifecycle.ts` event hook test, `test-session-manager.ts` `killAllActiveProcesses`); and a CLI that hung up on its own request keeps its entry for late-result recovery (`test-proxy-task.ts` recovery modes), as does a watchdog respawn (`test-respawn.ts`, completions carried to the replacement). **Every terminal-event test asserts both registries**, the proxy server's open HTTP requests (`ProxyMcpServer.pendingCallIds()`, read-only) and the broker's entries (`getPendingProxyCalls`), not merely that `kill()` ran or one promise rejected: with no deadline, an entry either side forgets to drop is permanent. What no event covers is a child that is alive and silent, which is what the start and inactivity watchdogs are for; they are unchanged and are not proxy deadlines. Keepalives are about the CLI's HTTP client, not the tool. Do not describe this change as "removing timeouts"; describe it as listening.

The events, each with the regression that proves the call is released: opencode's result resolves it (`test-proxy-task.ts` "proxy MCP initializes, lists Task, and resolves it through the broker"); an abort rejects the turn's pending calls at once and interrupts the CLI, whether it lands before content (`test-proxy-task.ts` "immediate abort rejects a buffered Task call"), after content (`test-process-lifecycle.ts` "an abort after content…"), or while opencode is running the tool with the stream already closed on its boundary, where the signal fires on a closed stream and the handler acts only if no later turn has attached to the process (`test-process-lifecycle.ts` "an abort while opencode is running the tool…"; before the fork-parity PR that abort did nothing and the call waited for the next message); the next user message rejects the previous turn's calls as orphaned and the CLI's HTTP request gets the error result (`test-process-lifecycle.ts` "a task call the previous turn left pending…"); the child dying mid-turn ends the turn as an error and rejects its calls, and the child dying between turns rejects them from `spawnClaudeProcess`'s exit handler with no turn attached (`test-process-lifecycle.ts`, both `exit-*` modes; the between-turns case was a real gap before the fork-parity PR, covered only by the 60-min timer); a deleted session and host exit reject them through `detachActiveProcess` (`test-process-lifecycle.ts` event hook test, `test-session-manager.ts` `killAllActiveProcesses`); and a CLI that hung up on its own request keeps its entry for late-result recovery (`test-proxy-task.ts` recovery modes), as does a watchdog respawn (`test-respawn.ts`, completions carried to the replacement). **Every terminal-event test asserts both registries**, the proxy server's open HTTP requests (`ProxyMcpServer.pendingCallIds()`, read-only) and the broker's entries (`getPendingProxyCalls`), not merely that `kill()` ran or one promise rejected: with no deadline, an entry either side forgets to drop is permanent.

If the CLI autoupdates underneath a long-running opencode, the cached version stops describing the binary actually being spawned, so a gated flag can be passed to a CLI that rejects it or withheld from one that supports it; swapping the binary mid-session is a plain correctness hazard besides. Both names were **read out of the 2.1.263 Mach-O** (`rg -a`, the same technique the CLI stream-event gotcha records), not assumed: `DISABLE_AUTOUPDATER` is parsed by `hQ()` as an update blocker, and `CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC` is read by `I()` as `"essential-traffic"` **and** returned by `dxe()` as a second, independent update blocker, so the two overlap on purpose. Anthropic's own runner sets `DISABLE_AUTOUPDATER:"1"` on the children it spawns, which is the same use this is. `cliHygieneEnv` lives in `src/cli-version.ts` rather than `session-manager.ts` because it exists to protect that module's cache, and because `src/claude-session-bun.ts` needs it too: `cli-version.ts` pulls in only `logger.ts`, so the interactive module stays cheap to import (it is also driven directly by `e2e-claude-session-bun.ts`). It **fills gaps only** and never overwrites, so `DISABLE_AUTOUPDATER=0` in the user's shell keeps the autoupdater and an empty string stays empty, which both vars read as off; that is the escape hatch, and it is why this needs **no provider option**. The interactive env moved out of the `Bun.spawn` literal into `interactiveSpawnEnv` purely so a test can reach it without a PTY. Tests: `test-spawn-env.ts` (7 cases; 4 fail with `cliHygieneEnv` stubbed to `{}`, the other 3 assert the constant or the absence of an override). - Reasoning stream parts are only started after the first non-empty `thinking_delta`. This prevents empty Thinking rows when the CLI opens a thinking block but streams no text. - opencode's own reasoning features (e.g. v1.17.0 "Added Claude Fable reasoning support", vLLM interleaved `reasoning` field) live in opencode's **native** Anthropic/vLLM runtime, which this plugin deliberately bypasses by routing through the `claude` CLI. There is nothing to "switch to" — the plugin implements reasoning itself (reasoning variants → thinking keyword + `--thinking`/`--thinking-display` flags → `thinking_delta` forwarding), and any model defined with `reasoning: true` (including `claude-fable-5`) inherits the full path automatically. Do not re-investigate adopting opencode's native reasoning; it would mean abandoning the CLI wrapper. - Model display names carry a list-price multiplier as a `(N×)` suffix (`src/models.ts` `defineModel`, via the `multiplier` field): haiku 1×, sonnet 3×, opus 5×, fable 10×, mythos 10×. These are exact ratios of published per-token price vs Haiku (input and output ratios coincide), so Fable/Mythos = 2× Opus. opencode has no native multiplier field, so the suffix is the only way it surfaces in the picker; it's display-only and model resolution still keys off `id`. `test-config-models.ts` asserts the suffixed names — update both if the format changes. @@ -136,7 +137,7 @@ These rules supersede the older lifetime-cache and process-cleanup wording in th - `createLiveToolInfoLoader()` shares one lazy `client.tool.list()` request within a `doStream` turn.

The CLI always emits a `stop_reason`, and `shouldAutoContinueIncompleteTurn` treats any `stop_reason` as authoritative (v0.4.17), so the keyword heuristic below that guard — `looksLikeFinalAnswer` / `looksLikeQuestion` / `looksLikeBlocker` and the whole v0.4.10–v0.4.15 idiom list — is dead code in practice, and `autoContinueIncompleteTurns: "smart"` behaves as `off`. @JWebCoder's PR #15 diagnosed this correctly; it was closed because the remedy (delete the guard) promotes the regex back to the deciding vote on every turn, which is exactly what v0.4.17 removed, and it also carried a `package-lock.json` this repo deliberately does not have. **The narrow change has since been made, and not the way that sentence originally proposed.** `isTruncationStopReason` (`max_tokens`, plus `max_output_tokens` as a defensive alias) now returns `{continue: true, reason: "truncated"}`, bounded by the attempt and elapsed rails, while every other `stop_reason` stays authoritative. It could not simply "fall through to the heuristic": the common truncation case is one long prose answer with no tool or reasoning activity, which dies at the `no-activity` gate a few lines below, so truncation had to be authoritative in the opposite direction instead. It runs at the default `autoContinueIncompleteTurns: "smart"`, which is what makes it reachable at all given everything else about that setting behaves as off. Do not delete the heuristic either — it is the fallback for CLIs that omit `stop_reason`. Tests: `test-auto-continue.ts` (five cases, all failing with the branch stubbed out). +- **Auto-continue never fires on current Claude Code CLI.** Measured 2026-08-19 from `~/.local/share/opencode-claude-code/plugin.log`: 53 decisions stopped at `reason: "end-turn"` with `attempts: 0`, 12 at `error`, and nothing else. **Re-measured 2026-09-20 against CLI 2.1.263 and the conclusion holds, but two sentences of the original are wrong and are corrected here.** The window was 2026-09-19T20:13Z to 2026-09-20T01:29Z (the log rotates at ~5 MB, which is what bounds it), 275 decision lines, of which only **47 are production**: the other 228 carry a `/var/folders/` cwd or a `claude-test-*` model id and are the suite's own fake CLIs. Split them before reading a tally or the picture is badly wrong. Production: 34 `end-turn` (`stop_reason: end_turn`), 13 `error` (`stop_reason: stop_sequence`), **zero continuations, every line `attempts: 0`**, and no `max_tokens` anywhere, so the truncation branch still has no production mileage. The two corrections: (1) `stop_sequence` is a stop reason this record never mentioned and it is now a third of production decisions, and it lands on `reason: "error"` because `snapshot.isError` is checked **before** the stop-reason guard. (2) **"The CLI always emits a `stop_reason`" is not strictly true on 2.1.263.** An interrupted turn's `result` carries `stop_reason: null` with `subtype: "error_during_execution"`, measured directly (see the abort probe below). The conclusion survives anyway, and for a reason worth keeping: that same result has `is_error: true`, and the `isError` check short-circuits above the guard, so the heuristic is still never consulted. The only `stopReason: null` lines that reach the heuristic in the whole log come from the fake CLI in `test-unattended-replay.ts`, which is what the fallback is for. Also re-checked on 2.1.263 and **not** found: any sign that the CLI continues itself, which would risk our nudge doubling up on a turn. A plain `-p` turn emits exactly one terminal `result` (`num_turns: 1`), and an interrupted turn emits exactly one error `result` and then stays silent until a new user message. The 515 real `replaying stdout the child emitted between turns` lines are **not** this: that is the known proxy-detach path (PR #35), not unprompted continuation. The stall and server-error cases the backlog claims were not reproducible cheaply and are therefore **not established either way**. Abort was re-verified live on 2.1.263 by driving the real CLI over stream-json stdin with exactly `interruptTurn`'s payload: `control_response` `subtype: "success"` came back in **1 ms** (now carrying `still_queued: []`, matching the new `interrupt_receipt_v1` / `interrupt_cancel_queued_v1` capabilities that `system`/`init` advertises), the turn ended 331 ms later, only **14 characters** streamed after the interrupt, and the same process answered the next turn cleanly with `stop_reason: end_turn`. Unparsed-but-forwarded stream events as of 2.1.263, reported and deliberately **not** implemented in that lane: the CLI's SDK allowlist forwards `tool_progress`, `tool_use_summary`, `prompt_suggestion`, `conversation_reset` and `command_lifecycle`, none of which `src/cli-events.ts` reads; `system` also has `hook_started` / `hook_response` subtypes (seen live), `compact_metadata` gained an optional `cumulative_dropped_tokens`, and `init` now carries `agents`, `capabilities`, `plugins`, `skills` and `slash_commands` among others. `conversation_reset` is the one worth a look first, since a reset would invalidate the `toolCallMap` and pending-proxy bookkeeping. `/goal` and `/loop` **are** advertised in `init.slash_commands` under `--print` on 2.1.263 (159 commands listed), which confirms the backlog's claim that far; neither was executed, deliberately, because `/loop` can loop. The original reasoning, as corrected above: the CLI emits a `stop_reason` on every turn that is not aborted, and `shouldAutoContinueIncompleteTurn` treats any `stop_reason` as authoritative (v0.4.17), so the keyword heuristic below that guard (`looksLikeFinalAnswer` / `looksLikeQuestion` / `looksLikeBlocker` and the whole v0.4.10 to v0.4.15 idiom list) is dead code in practice, and `autoContinueIncompleteTurns: "smart"` behaves as `off`. @JWebCoder's PR #15 diagnosed this correctly; it was closed because the remedy (delete the guard) promotes the regex back to the deciding vote on every turn, which is exactly what v0.4.17 removed, and it also carried a `package-lock.json` this repo deliberately does not have. **The narrow change has since been made, and not the way that sentence originally proposed.** `isTruncationStopReason` (`max_tokens`, plus `max_output_tokens` as a defensive alias) now returns `{continue: true, reason: "truncated"}`, bounded by the attempt and elapsed rails, while every other `stop_reason` stays authoritative. It could not simply "fall through to the heuristic": the common truncation case is one long prose answer with no tool or reasoning activity, which dies at the `no-activity` gate a few lines below, so truncation had to be authoritative in the opposite direction instead. It runs at the default `autoContinueIncompleteTurns: "smart"`, which is what makes it reachable at all given everything else about that setting behaves as off. Do not delete the heuristic either: it is the fallback for CLIs that omit `stop_reason`. Tests: `test-auto-continue.ts` (five cases, all failing with the branch stubbed out). - **A compaction turn must never be nudged, and truncation-continue is what made that reachable.** `AUTO_CONTINUE_PROMPT` says "Do not summarize; keep working", the exact inverse of a `/compact` turn's job, and continuation reopens the same stream instead of closing it, so the non-summary text would be appended to what opencode stores as the session summary. `doStream` builds `autoContinueState` inline and passed `self.config.autoContinueIncompleteTurns` straight through with no `compactionMode` term, which was harmless only while every `stop_reason` returned `continue:false`. `autoContinueEnabledFor(compactionMode, configured)` now gates it, exported purely so the wiring is testable rather than only the pure decision function. Bounded at 8 attempts either way, so the pre-fix worst case was an inflated and corrupted summary, not a hang. Found by a subagent review of the truncation change, not by the test suite, which had no compaction case at all. - **opencode's `tool.definition`, `experimental.session.compacting` and `experimental.compaction.autocontinue` hooks were evaluated on 1.18.29 and deliberately NOT adopted** (issue #24). `tool.definition` fires only inside opencode's own `ToolRegistry.tools`, over built-ins plus filesystem/plugin-declared tools; **MCP tools are not in that registry**, and the MCP assembly path triggers only `tool.execute.before`/`after`. So it cannot reach the proxy defs this plugin serves to the Claude CLI, and it could not do the job anyway: opencode appends `describeTask`'s agent list *after* the hook returns, which is the exact ordering `overlayTaskProxyDescription` exists to control against Claude Code's description truncation. Its input is `{toolID}` alone, with no session/provider scope, so any edit would reshape tools for every provider in the user's opencode. The compaction hooks are a prompt-authoring hook and a veto on opencode's post-compaction synthetic turn; neither is registered here, so they cannot interact with this plugin's auto-continue, and they operate on a different boundary regardless (an opencode turn versus a CLI turn inside one opencode turn). `experimental.session.compacting` would also be strictly worse for detection than `opencodeAgent === "compaction"`, which is available synchronously per call and drives the model override, effort exemption, session key and lean spawn. - **v2 plugin API: do not migrate, and the reload that exists is not the one we want** (tracker is issue **#31**, checked on 1.18.29; #24 is closed and is not the tracker any more). `Reload` is `{ reload: () => Promise }` (`dist/v2/promise/registration.d.ts`), and `catalog`, `agent`, `command`, `integration`, `reference` and `skill` carry it while **`aisdk` does not** (`dist/v2/promise/context.d.ts`). So model *metadata* can be re-transformed at runtime through `CatalogHooks = Hooks<{transform: CatalogDraft}>`, but the model implementation path cannot. That does not touch this plugin's actual pain point: provider options are captured at `createClaudeCode()` and baked into each `ClaudeCodeLanguageModel`, and `catalog.reload()` re-runs a catalog transform rather than re-reading `provider.claude-code.options`. The restart requirement is opencode's config loading, not the plugin API. Even the metadata win is nil here, since `src/models.ts` is a static registry that only changes on package upgrade, which requires a restart anyway. v1 is **not deprecated**: all five `@deprecated` markers in `dist/index.d.ts` are unrelated (auth-prompt `condition` → `when`, and the `AuthOuathResult` typo alias). diff --git a/README.md b/README.md index 79b2066..6732f80 100644 --- a/README.md +++ b/README.md @@ -334,6 +334,8 @@ Every variable the plugin itself reads, in one place.

You MUST use the `compress` tool now" reminders were unobeyable under this provider: the tool is in `client.tool.list()` (confirmed on 1.18.31, alongside `question`, `task`, `skill`, `gemini_quota`, `quota_status`) and was simply never offered. `proxyOpencodeTools` is the explicit allowlist that forwards it, **empty by default**, and never automatic because a forwarded tool executes in opencode with the calling agent's permissions. The collision is resolved **twice, at two layers, and both are load-bearing**: (1) at def level, `taken` holds the names already claimed by `enrichedProxy` and the MCP defs, so a forwarded `compress` is dropped with a WARN rather than becoming a second def of the same name; (2) at interceptor level, `ensureProxyServer` takes an explicit `interceptCompress` flag instead of keying on `tools.some(t => t.name === "compress")`. Layer 2 is the one a def-level check cannot see and the one that actually bit: with **only** the forwarded def present there is nothing to collide with, and the old name-keyed condition would have answered opencode's tool with the plugin's in-process reset ("Summary stored...") while opencode never saw the call. The plugin's own tool wins when both are configured, because it is named explicitly in `proxyTools` and it manages the window that overflows here. `buildAppendedSystemPrompt` follows the same precedence and has a **third** note variant (`CLAUDE_CLI_OPENCODE_COMPRESS_NOTE`) that says the forwarded tool compresses **opencode's** transcript and not the Claude session: reusing the plugin's note would tell the model its context had been discarded when it has not. Live-verified 2026-09-19 on CLI 2.1.263 + opencode 1.18.31 with dcp loaded: `forwarding opencode tools through the proxy {"tools":["compress"]}`, proxy started with `tools: ["bash","compress"]`, `proxy-mcp tool call received {"toolName":"compress"}`, queued through the normal broker, and dcp really ran (`Compressed 3 messages into [Compressed conversation section]`). **The wrinkle to expect:** dcp's compress rewrites opencode's message history mid-turn, so opencode aborts the provider stream at that tool boundary (`abort between proxy tool boundaries; releasing pending calls`) and the result reaches the model on the next step through the issue #29 text path (`rendering opencode-side tool result as text`). The turn completes and nothing leaks, but do not read that abort as a regression. Collision verified live in the same session: WARN emitted, exactly one `compress` in the server's tool list, and the interceptor answered. Tests: `test-compress-tool.ts` (forwarding, unknown name, unreachable registry, both collision layers, note selection). - **Probing any of this live needs a scratch `XDG_CONFIG_HOME`, not just `OPENCODE_CONFIG`.** opencode **merges** the `plugin` array with the user's global config, so a scratch config still loads the parent checkout's copy of this plugin and its provider registration can win. The symptom is silent and cost three paid runs: the option is visibly present in `GET /config` provider options, yet the model behaves like a build without it, because the language model came from the other copy. Assert `plugin ready` appears exactly **once** in `plugin.log`. Two smaller traps in the same family: a leftover `opencode.json` in a **parent directory** of the probe's cwd beats `OPENCODE_CONFIG`, so give each probe its own cwd; and an account provider's model id carries the marker (`claude-haiku-4-5@appical`), where a bare id 500s as an opaque `UnknownError`. - **`stripContextReminders`** (`message-builder.ts`) is the other half, also **off by default**. dcp anchors its nudges into **message text** (`lib/messages/inject/utils.ts` appends to an existing text part or splices a synthetic one), not into the system prompt, so each is re-sent with every message that carries it; all of them are wrapped in ``. The strip runs once at the top of `getClaudeUserMessage`, which is why the fresh-session rebuild and the `/compact` transcript get it for free instead of each needing a flag. Three rules: it is matched **wherever the block sits**, because dcp appends `` after one and an end-anchored check would miss it (the same trap the `/btw` strip hit in production); emptied parts are kept as empty strings rather than dropped, since a nudge can be a message's only text part and removing it could leave a user message with no content at all; and it must never touch opencode's own `` blocks, which are opencode's instructions to the model. `shouldStripContextReminders` turns it off as soon as `compress` is named in either list, resolved from **config alone** so it is answerable before the spawn block (`userMsg` is built well ahead of it) and so a configured-but-unregistered name errs toward keeping the reminder. Tests: `test-get-claude-user-message.ts`. +- **Account failover is ON by default, and the thing that makes that safe is that the pick is the consent** (`src/account-failover.ts`). With more than one account configured, a usage limit ends the turn on opencode's native `question` form (the same mechanism as the plan-mode bridge: `finishWithQuestionCall` emits `tool-input-start` + `tool-call` and finishes on `tool-calls`, and the answer arrives on the NEXT `doStream` as a `tool-result` with the same id) instead of the rate-limit error. Nothing moves until an account is picked, and an unanswered form waits at zero cost. Seven things hold it together and none is optional: + 1. **Detection is two exact signals, never "an error".** `isAccountLimitError` fires on a `rate_limit_event` that `isRateLimitRejected` accepts, or on one of `ACCOUNT_LIMIT_PATTERNS` (the two texts this file already records). A generic 4xx opening this form would silently move where usage is billed, which is the one failure mode that would be worse than the error it replaces. The rate-limit branch parses the event **separately from `reportRateLimitEvent`**, which dedupes per process and returns null on a repeat: the second rejection in a session is still a rejection this turn must act on. + 2. **The override is keyed on the LIMITED ACCOUNT, not the session.** A rate limit is a property of the account, so one pick covers every session on it and a subagent follows its parent for free. That is also why `isAccountFailoverQuestionActive` refuses child sessions (`fetchSessionParentId` in `runtime-status.ts`, off the same `GET /session/{id}` as `fetchSessionDirectory`): a form in a subagent session is one nobody is looking at. + 3. **`--resume` can never cross accounts**, because transcripts live under the account's own `CLAUDE_CONFIG_DIR`. A switch is therefore always a fresh session with the thread replayed: the prologue drops the active process **and** the Claude session id when `ActiveProcess.cliPath` differs from the resolved one, which is what makes `includeHistoryContext` true, and is equally what switches back once the override expires. The comparison is guarded on `active?.cliPath &&` so the interactive shim, which carries no path, is never dropped by it. + 4. **The `@account` suffix must come off the model id.** `parseModelId` keeps it on purpose (the source account's own wrapper strips it), but a failover spawn goes through a *different* wrapper, or the bare binary for `default`, and `--model claude-opus-5@appical` is rejected outright. `resolveFailoverSpawn` strips it; `parseModelId` is called on `failover.modelId`, not on `effectiveModelId`. + 5. **A reset time that is not in the future degrades to "until opencode restarts".** Found by the fake-CLI test, not by reasoning: with `until` behind `now` (clock skew, a stale `resetsAt`), `resolveAccountOverride` deleted the override on the very next read, so the switch the operator had just authorised was undone before it ran and the turn re-hit the same limit and asked again. `setAccountOverride` clamps it. + 6. **The dialog must never be replayed.** The synthetic `question` tool-call and its `tool-result` carry `account_failover_` ids Claude never issued or saw, so `stripAccountFailoverParts` is called from `filterSideQuestionHistory` (both transcript rebuild paths) and from `buildFailoverContinuationPrompt`. `FAILOVER_MARKER` is registered in `PLUGIN_NOTE_MARKERS` and the note is enqueued as its own text part, the same rule every `▌` line follows. A message left with no content after the strip is dropped rather than replayed empty. + 7. **`doGenerate` takes the override with no dialog of its own.** A title or no-tools call must not ask anything, but it must follow the account the conversation moved to, or it quietly bills the limited one. + Excluded entirely: compaction (its answer would have nowhere to go) and the interactive transport (TUI stdin, no proxy server). `clearAccountFailoverQuestions` is wired into `deleteClaudeSessionId` next to `clearExitPlanModeQuestions`. `ExitPlanModeQuestionCall` is now an alias of the shared `QuestionToolCall`, and `unwrapToolOutput`/`collectAnswerStrings` are exported rather than copied. Tests: `test-account-failover.ts` (23, including the negative detection cases and a fake CLI that answers differently depending on the `CLAUDE_CONFIG_DIR` it was reached through, which is how the routing, the stripped `--model` and the `` replay are asserted). **Not live-verified**: the whole path is offline only, so the first real-account run is the one that proves it. - `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`). Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. @@ -191,6 +200,7 @@ These rules supersede the older lifetime-cache and process-cleanup wording in th - `AGENTS.md` dedup against the forwarded system prompt: `test-compaction-model.ts`. - AskUserQuestion deny/stop behavior (`denyMessageForTool`, `isAskUserQuestionTool`): `test-ask-user-question.ts`. - Plan-mode approval bridge (`isPlanModeQuestionActive`, `createExitPlanModeQuestionCall`, `consumeExitPlanModeQuestionResult`): `test-exit-plan-mode-question.ts`. +- Account failover (limit detection incl. its negative cases, the account-scoped override and its expiry clamp, `resolveFailoverSpawn` for a default vs a named target, the form, every answer classification, the transcript strip and the continuation prompt, plus a fake CLI driving a real `doStream` through ask / switch / stop): `test-account-failover.ts`. - Compress tool (proxy interceptor path, compression store, compress vs default runtime note), plus `resolveProxyOpencodeToolDefs` and both layers of the `compress` name collision: `test-compress-tool.ts`. - dcp reminder stripping (`stripContextReminderBlocks`, `stripContextReminders`, `shouldStripContextReminders`, and that it is off by default): `test-get-claude-user-message.ts`. - Config-path model metadata injection (`configModelsForProvider`): `test-config-models.ts`. diff --git a/README.md b/README.md index 6732f80..6f74f09 100644 --- a/README.md +++ b/README.md @@ -197,6 +197,34 @@ CLAUDE_CONFIG_DIR="$HOME/.claude-work" claude auth login The account model IDs are internally suffixed, for example `claude-sonnet-4-6@work`, so long-lived Claude subprocess sessions do not collide across accounts.
