Overview & goals + +SPEC-3 makes the fleet **dual-arsenal**: a `subagent` run targets one of two backends — **Pi** (the SPEC-1/2 SDK-session child) or **Claude Code** (`claude -p` child process) — chosen by the agent profile's `backend` frontmatter field. The engine stays backend-agnostic; a new `BackendRegistry` routes. The moat (memory-hydrate / vision / `todo`-exclusion / no-leakage) extends into the CC backend through *its* native mechanisms (prompt-baking + flag translation), with the one genuine gap (CC vision has no `describe_image` fallback) declared visibly in a per-backend armory chip. Backend-native `session_key` resume works in both. A new `/fleet` Backends view shows backend availability, version, schema, and hook parity. + +**In scope (v0.3):** +- `backend: "pi" | "claude"` frontmatter field (profile pins backend; Q2=A). +- `sessionKey` frontmatter field (default = profile name) + backend-native resume (Q3=A). +- `BackendRegistry` + `Backend` descriptor (Q5=B) — the data source for routing + the Backends view. +- `createClaudeChildFactory` + `ClaudeChildSession` — the CC adapter (streaming `claude -p --output-format stream-json`; Q4=A). +- The moat translated into CC: memory via `--append-system-prompt`; `todo` via `--disallowed-tools`/`--allowed-tools` (prompt-nudge fallback); vision pass-through-only (Q1=B, the `v~` gap declared). +- `detectClaude()` version + stream-json schema smoke at init; fail-loud at the backend (Q4=A). +- `/fleet` Backends view (read-only) + Agents-view backend badge. +- `general-purpose-cc` builtin (sibling to `general-purpose`). + +**Out of scope (deferred — §12):** fan-out synthesis primitive; per-spawn `backend` override; cross-backend resume (session hops Pi→CC); `BackendPort` interface lift; Codex backend; per-backend model list in Backends view; inline Backends editing; async/background CC runs; cost-accounting normalization. + +**Done bar (v0.3):** A profile with `backend: claude` spawns a real `claude -p` child through the CC factory; the run is memory-hydrated, `todo`-excluded, and tracked in armory-todo like any Pi run; vision is pass-through-only with the gap visible in the chip; `session_key` resume works in both backends; the `/fleet` Backends view renders availability + version + schema + hook parity; `claude` absent or schema-drifted fails loud at the backend. Day-one dual-arsenal via `general-purpose` (pi) + `general-purpose-cc` (claude) builtins; fan-out = parent calls `subagent` twice. + +**Competitive dimension (PRD §8 SPEC-3):** Dual-arsenal — only kky42 attempts, weakly. Fleet ships it with a visible, honest hook-parity contract + native resume in both backends. + +--- + +## 2. Architecture — the `BackendRegistry` + +### 2.1 The creation seam is unchanged; the metadata is new + +SPEC-1 established `ChildSessionFactory` (`create(opts) => {session, model}`) as the backend-agnostic creation seam. SPEC-3 does **not** rename it a `BackendPort` (Q5=B — YAGNI for two backends). Instead, SPEC-3 adds a `BackendRegistry` that maps a backend id → a `Backend` descriptor holding the factory *plus* the metadata Q1/Q4 need: + +```ts +interface Backend { + id: "pi" | "claude"; + factory: ChildSessionFactory; + available: () => boolean; // pi → true (always); claude → detect result (cached) + versionInfo: () => BackendVersionInfo | null; + hookParity: BackendHookParity; // declared constant, not inferred +} +``` + +The engine consults `registry.get(agentDef.backend).factory`; the Backends view reads `registry.list()`. The creation seam (`ChildSessionFactory`) is SPEC-1's, untouched. + +### 2.2 The two backends + +| Backend | Factory | Available | Hook parity | +|---|---|---|---| +| `pi` | `createChildSessionFactory` (SPEC-2, unchanged) | always `true` | `t✓ m✓ v✓` | +| `claude` | `createClaudeChildFactory` (SPEC-3 NEW) | `detectClaude()` result (cached at init) | `t✓ m✓ v~` | + +### 2.3 The moat boundary (Q1=B made concrete) + +The moat is fleet-owned orchestration applied *through* each backend's native mechanisms. Pi gets it via loader injection (`CustomResourceLoader` + `customTools` + `excludeTools`); CC gets it via prompt/flag translation (`--append-system-prompt` + `--disallowed-tools`). The contract is the `Backend.hookParity` struct — **declared per backend, read by the view, never inferred at spawn time**. Where a hook can't be delivered (CC vision fallback), the chip says so (`v~`), and §12 records the gap. + +### 2.4 The resume boundary (Q3=A) + +`sessionKey` is a per-profile stable id (default = profile name). On spawn, each backend persists its native session id into `runRecord.backendSessionId` (Pi: file-backed `SessionManager` session id; CC: the `session_id` from the stream-json init event). On a re-spawn of the same `sessionKey`, the engine feeds that id to the backend's resume primitive. **Sessions never hop backends** — each backend resumes its own. + +### 2.5 What does NOT change + +`spawnSubagent`'s shape, the `subagent` tool params, the turn budget, the concurrency lock, the todo-sync port, the run registry, the Agents/Fleet views. SPEC-3 is *additive*: one new factory, one registry, two new frontmatter fields, one new view, the CC adapter module, one small Pi-factory change (inMemory → file-backed `SessionManager` for resume). The PRD §8 `.pi/subagents/` wording is reconciled → profiles stay in `.pi/agents/` (+ `~/.pi/agent/agents/` + builtins); `backend` is a frontmatter field on the same files. + +--- + +## 3. Components (file layout — additions/changes vs SPEC-2) + +SPEC-3 is additive. **NEW** files are new; **MOD** files are modified.

The Pi factory (`createChildSessionFactory`) and all SPEC-2 modules (`child-loader`, `memory-hydrate/`, `vision/`, `todo-sync/`) are **untouched** except the one-line Pi-factory `SessionManager.inMemory()` → file-backed change (§3.1). + +### 3.1 The one SPEC-2 module touched: Pi factory `SessionManager` + +To enable Pi-side resume, `createChildSessionFactory` switches from `SessionManager.inMemory()` to a file-backed manager (so the session id survives across spawns). Contained: one line + the resume-store write/read around it. No behavior change for non-resume runs (a fresh `sessionKey` simply starts a new file-backed session). Recorded as the only SPEC-2 surface SPEC-3 touches. + +--- + +## 4. The CC adapter — `claude -p` → `ChildSession` + +### 4.1 The invocation + +The CC factory spawns `claude` in streaming interactive mode: + +``` +claude -p \ + --output-format stream-json \ + --input-format stream-json \ + --verbose \ + --model # omitted if agentDef.model unset → CC default + --append-system-prompt "" # Q1=B memory baking + --disallowed-tools "todo" # if --disallowed-tools supported (version-detect) + --allowed-tools "" # when agentDef.tools pins tools (enforces todo exclusion) + --max-turns # if supported (version-detect) + --resume # when resume-store has an id for sessionKey +``` + +**Model string:** `agentDef.model` for a CC profile is a CC model identifier passed verbatim to `--model`. Fleet does **not** parse `provider/id` for CC (that's a Pi convention). Omitting `model` → no `--model` flag → CC default. + +### 4.2 NDJSON stream → `ChildSessionEvent` mapping (`claude-events.ts`) + +| CC NDJSON event | Fleet `ChildSessionEvent` | Notes | +|---|---|---| +| `{type:"system", subtype:"init", session_id, …}` | forwarded as `{type:"session_init", backendSessionId}` | capture + persist to resume-store; the engine reads it to stamp `runRecord.backendSessionId` (§4.3, §7) | +| `{type:"assistant", message:{role:"assistant", content:[{type:"text",text}]}}` | `{type:"message_end", message:{role:"assistant", content:[{type:"text", text}]}}` | `finalText` accumulation | +| `{type:"assistant", message:{usage:{…}}}` | merged into the same `message_end` | `usage.cost.total` computed from CC token fields (× per-token cost, or CC's own cost field if present) | +| `{type:"result", subtype:"success"\|"error_max_turns"\|…}` | `{type:"turn_end"}` | drives turn budget; `error_max_turns` → `failed` run | +| `{type:"user", …}` *(echo of our stdin write)* | *(filtered)* | not fed back to the engine | +| `{type:"error", …}` | surfaced as a run error | session rejects; engine records `runError` | + +**Unknown event types** are logged at debug + forwarded as-is (forward-compat; CC may add types we don't need). The schema smoke catches whole-shape drift (init missing `session_id`) → backend `available:false`. + +### 4.3 `session_id` capture + resume lifecycle + +**On init event:** `ClaudeChildSession` (1) stashes `session_id` on the instance, (2) writes `resumeStore.set("claude", sessionKey, session_id)`, (3) forwards a fleet-internal `{type:"session_init", backendSessionId}` event through `subscribe` (the engine's handler stamps `runRecord.backendSessionId` + `runRecord.sessionKey`). This adds an optional `backendSessionId?: string` field to `ChildSessionEvent` (`src/engine/spawnSubagent.ts`) — the only change to the `ChildSession`/`ChildSessionEvent` contract in SPEC-3; Pi's factory emits the same `session_init` event once its file-backed `SessionManager` session id is known. + +**On re-spawn** of the same `sessionKey`: the factory reads `resumeStore.get("claude", sessionKey)` → if present, passes `--resume `; CC replays its own history natively (no transcript normalization). **Stale-id fallback:** if `--resume` fails (CC evicted the id), the factory catches the error, clears the resume-store entry, re-spawns *without* `--resume` (fresh session), and surfaces a visible warning to the parent. Never a silent failure. + +**Pi side (symmetry):** the Pi factory captures the file-backed `SessionManager` session id, writes `resumeStore.set("pi", sessionKey, id)`, and on re-spawn calls `SessionManager.resume(id)` with the same stale-id fallback. + +### 4.4 `prompt` / `abort` / `dispose` + +- **`prompt(text)`**: writes `{type:"user", message:{role:"user", content:[{type:"text", text}]}}\n` to stdin; resolves when the matching `result` event arrives (turn boundary, not session end — session stays alive for resume). Matches Pi's `session.prompt` semantics. +- **`abort()`**: `proc.kill("SIGTERM")`. Stream close → synthetic `turn_end` (so the budget path isn't bypassed) → engine records `status:"aborted"`. Hard kill is the only mechanism; abort is best-effort cancellation. +- **`dispose()`**: `proc.kill()` (SIGKILL if alive) + `stdout.destroy()` + `stdin.end()` + remove listeners. Idempotent. Called by the engine in `finally`. + +### 4.5 Turn budget mapping + +- Pass `--max-turns ` if supported (version-detect records it); CC stops itself. +- Fleet's `turn_end` counter is the **belt**: excess `turn_end` events → engine `budget.consume()` → `session.abort()`. +- CC `result.subtype === "error_max_turns"` → `failed` run with `"hit turn budget"` (same message shape as Pi, consistent regardless of backend). + +### 4.6 The moat in CC (recap) + +| Hook | Pi (SPEC-2, unchanged) | CC (SPEC-3) | Parity | +|---|---|---|---| +| memory-hydrate (3-scope) | `CustomResourceLoader` composes `systemPromptOverride` | `--append-system-prompt` with the same `memoryPort.renderScopes()` string | `m✓` | +| `todo` excluded | `excludeTools:["todo"]` + `noExtensions:true` | `--disallowed-tools`/`--allowed-tools` (kebab-case; exact names confirmed by `detectClaude()`) + prompt-nudge fallback | `t✓` | +| vision (capability-aware) | `describe_image` injected via `customTools` iff child text-only | pass-through only (CC's own model multimodal); **no fallback** | `v~` | +| no host-extension leakage | `noExtensions:true` | inherent (CC has no fleet extensions) | ✓ | + +The `v~` is the one declared gap, visible in `Backend.hookParity.vision = "~"` → Backends view + Agents chip → never a spawn-time surprise. + +--- + +## 5. The CC detector + version-detect (`claude-detector.ts`) + +Runs once at extension init (cached on the `Backend` descriptor): + +1. **`claude --version`** → parse version; missing/unparseable → `null` (backend unavailable). +2. **Schema smoke**: spawn a throwaway `claude -p --output-format stream-json "ping"`; read the init event; confirm shape `{type:"system", subtype:"init", session_id, …}`. +3. **Flag support probe**: check `claude --help` (or a version-table) for `--disallowed-tools` / `--allowed-tools` / `--max-turns` / `--resume` support (kebab-case; exact names confirmed here, not hardcoded in the factory) → records the flag matrix the factory consults. +4. Return `{ version, schemaOk, flagSupport, note? }`. + +**Fail-loud at the backend (Q4=A):** if `schemaOk=false`, the `claude` backend is registered `available:false` with a note; `backend:claude` profiles fail fast at spawn with the actionable error ("claude backend unavailable: schema drift — fleet supports CC ≥ "). Never a silent degradation. + +--- + +## 6. Frontmatter schema additions + +Extending SPEC-1 §7.2 / SPEC-2 §6 with two new fields. Pattern unchanged: named field, sensible default, toggleable — the moat/routing as a visible contract. + +| Field | v0.3 | Default | Notes | +|---|---|---|---| +| `backend` | ✅ | `"pi"` | `"pi"\|"claude"`; pins the profile's backend (Q2=A). Invalid → `FrontmatterError` listing valid backends. | +| `sessionKey` | ✅ | profile `name` | stable id for backend-native resume (Q3=A). Set explicitly to share resume state across differently-named profiles (rare). | + +**`AgentDef` diff:** +```ts ++ backend: "pi" | "claude"; // default "pi" ++ sessionKey: string; // default = name +``` +`parseAgentFile` validates `backend` against the registry's known ids (typo `backend: claud` caught at load, not spawn). + +### 6.1 The builtins + +`general-purpose` (unchanged, `backend` implicit `pi`) stays the Pi day-one agent.

Day-one fan-out: `subagent(general-purpose, …)` + `subagent(general-purpose-cc, …)`. + +--- + +## 7. The spawn lifecycle — what changes from SPEC-1 §5 / SPEC-2 §7 + +The engine gains one lookup + two run-record fields; everything else is unchanged. + +1.

Resolve model (unchanged; CC factory passes verbatim, doesn't parse `provider/id`). +4. Resolve tools/memory/vision ports (unchanged; the CC factory consumes the same ports). +5. **NEW:** read `resumeStore.get(backend.id, agentDef.sessionKey)` → pass to the factory as `resumeId`. +6. Spawn child via `backend.factory.create(opts)` (unchanged interface). +7. Subscribe, run, budget, abort — unchanged. +8. **NEW:** the session emits `{type:"session_init", backendSessionId}` through `subscribe` (§4.3); the engine stamps `runRecord.backendSessionId` + `runRecord.sessionKey`. +9. Finish run + todo-sync reconciliation (unchanged). + +`SpawnOptions.childFactory` is replaced by `SpawnOptions.backendRegistry: BackendRegistry` (the engine looks up the factory).

Decision log (brainstorm) + +| Q | Decision | Rationale | +|---|---|---| +| Q1 (moat parity in CC) | **B — graceful degradation.** Memory baked into prompt (achievable); `todo` excluded via `--disallowed-tools`/prompt-nudge (achievable); vision pass-through-only with the `v~` gap **declared** in the per-backend armory chip. | Keeps the moat's *intent* in CC where the mechanism exists; honestly records the one real gap (no `customTools` → no `describe_image` fallback); the chip makes the contract visible (SPEC-1 §7.2 "moat as visible contract"). A over-engineers against a CLI we don't control; C undersells what's achievable. | +| Q2 (routing model) | **A — profile pins `backend`.** Fan-out = two profiles (`foo-pi.md` + `foo-cc.md`); no `backend` tool param; engine unchanged. | Literal PRD glossary reading ("profile = backend + model + thinking + tools + role prompt"); chip is a **static file property** (no spawn-time inference → no silent `v~` degradation); simplest engine; dual-arsenal visible at rest in the registry. Drift cost is small and a feature (explicit). | +| Q3 (`session_key` resume) | **A — backend-native resume.** `sessionKey` per profile (default = name); each backend resumes its own prior session (`SessionManager.resume` / `--resume `); `backendSessionId` on the run record. | Only sensible reading of "across backends" — a session hopping Pi→CC needs a shared transcript format neither backend produces (SPEC-6+ research, not a real use case). Both backends have native resume primitives. C would drop a named PRD §8 deliverable. | +| Q4 (CC execution mode) | **A — streaming (`--output-format stream-json`).** Version-detect at adapter construction; fail-loud at the backend. | The `ChildSession` interface is event-based by design; one-shot violates `subscribe`/`abort`/turn-budget. `session_id` (for Q3=A resume) comes from the stream-json init event. Version-detect (not silent runtime fallback) is the PRD §9 mitigation — fail-loud at the backend, degrade-soft at the hook level (Q1=B), never silently. | +| Q5 (abstraction shape) | **B — `ChildSessionFactory` (unchanged) + `BackendRegistry` + `Backend` descriptor.** No `BackendPort` interface. | `ChildSessionFactory` is already the creation seam (SPEC-1 got it right); the registry is the natural home for the metadata Q1/Q4 need (hook-parity, version, availability). YAGNI against A's port + adapters for one extra backend; a third backend is a drop-in descriptor (no refactor). C bifurcates the engine + duplicates wiring. | +| (frontmatter shape) | `backend` + `sessionKey` are named fields with sensible defaults — consistent with `todoSync`/`memoryHydrate`/`vision`. Per-spawn `backend` override is the SPEC-6 power-knob. | SPEC-1 §7.2 pattern: the moat/routing as a visible, toggleable contract. | +| (PRD `.pi/subagents/` wording) | Reconciled → profiles stay in `.pi/agents/` (+ global + builtins); `backend` is a frontmatter field on the same files. | Same flavor as SPEC-2's "cursor in child" reconciliation + SPEC-1 §7.3's "role-per-phase" flag for SPEC-4. | +| (Pi factory SessionManager) | Switch `inMemory()` → file-backed so Pi-side resume works. The only SPEC-2 module SPEC-3 touches; one contained line. | Resume requires a session id that survives across spawns; inMemory can't. No behavior change for non-resume runs. | + +--- + +## 15.

Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Make the fleet dual-arsenal — a `subagent` run targets one of two backends (Pi or Claude Code) chosen by the agent profile's `backend` frontmatter field — with the moat translated into CC via prompt/flag mechanisms (vision gap declared), backend-native `session_key` resume in both, and a new `/fleet` Backends view. + +**Architecture:** A `BackendRegistry` maps a backend id → a `Backend` descriptor (`{ id, factory, available, versionInfo, hookParity }`); the engine consults it by `agentDef.backend`. The creation seam (`ChildSessionFactory`, SPEC-1) is unchanged. A new `createClaudeChildFactory` spawns `claude -p --output-format stream-json`, parses NDJSON into `ChildSessionEvent`s, captures the `session_id` for resume, and maps `abort`/`dispose` to child-process signals. Memory is baked into `--append-system-prompt`; `todo` excluded via `--disallowed-tools` (prompt-nudge fallback); vision is pass-through-only (`v~` gap declared in `Backend.hookParity`). `detectClaude()` runs once at init (version + stream-json schema smoke + flag-support probe); fail-loud at the backend. A `ResumeStore` maps `sessionKey → backendSessionId` per backend (file-backed); the engine stamps `runRecord.backendSessionId` from a new `session_init` event both factories emit. + +**Tech Stack:** TypeScript (raw `.ts` via tsx, no build), pi `^0.81.1` SDK (`createAgentSession`, `SessionManager`, `ModelRuntime`, `ModelRegistry`), `node:test` via tsx, `node:child_process` (`spawn`), `@getpipher/armory-memory`, `@getpipher/armory-todo`, `typebox`. + +## Global Constraints + +- **No build step** — raw `.ts` via tsx at runtime; `pnpm typecheck` + `pnpm test:run` (node:test via tsx) before release. +- **Test runner:** `node --import tsx --test test/*.test.mts` (Node 24 won't type-strip under `node_modules`). Use `pnpm test:run`. +- **pi target:** `^0.81.1`. SDK imports from `@earendil-works/pi-coding-agent`; `SessionManager.create(cwd)` for new file-backed Pi sessions, `SessionManager.open(path)` for resume; the `session` object exposes `sessionId: string` + `sessionFile: string | undefined`. +- **Additive only** — the Pi factory (`createChildSessionFactory`) and all SPEC-2 modules (`child-loader`, `memory-hydrate/`, `vision/`, `todo-sync/`) are untouched except Task 9's one-line `SessionManager.inMemory()` → `SessionManager.create(cwd)` + `session_init` emission (recorded in SPEC-3 §3.1 + §12). +- **CC CLI flags are kebab-case** (`--disallowed-tools`, `--allowed-tools`, `--max-turns`, `--resume`, `--append-system-prompt`, `--output-format stream-json`); exact flag names are confirmed by `detectClaude()` at init (version-detect), never hardcoded in the factory. +- **Hook parity is declared, not inferred** — `Backend.hookParity` is a constant per backend (`pi: t✓ m✓ v✓`, `claude: t✓ m✓ v~`); the chip is a static backend property, never computed at spawn time. +- **Single-writer discipline** — the child never writes to armory-todo; only the fleet engine does. CC's `todo` is excluded via `--disallowed-tools`/`--allowed-tools` (prompt-nudge fallback). +- **No AI attribution** in commits/PRs/files. +- **One commit per task**; conventional branch `feat/spec-3-cross-harness-peers` (cut at execution time, not during planning). +- **getpipher conventions:** EditorTheme gotcha — `ctx.ui.custom` receives full `Theme` (import from `@earendil-works/pi-coding-agent`); `ctx.ui.setEditorComponent` receives `EditorTheme`.

session_init stamps runRecord MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit SpawnOptions.childFactory → backendRegistry; engine looks up backend by agentDef.backend + fails fast when unavailable. ChildSessionEvent gains backendSessionId; RunRecord gains backendSessionId + sessionKey. The session_init event stamps the run record for resume. Ripples to the tool + panel + index wiring (pulled forward from Task 12 to keep typecheck green per-task): SubagentToolDeps + FleetPanelDeps now carry backendRegistry; index.ts builds a minimal pi-only BackendRegistry (Task 12 adds claude detection).

NOTE: RECTOR's claude OAuth is expired, so CC task output is an auth-failure message; the fleet wiring is correct, the auth is an env issue to re-auth. --- docs/SPEC-3-smoke-checklist.md | 26 +++++++++++++++ scripts/spec-3-smoke.mts | 59 ++++++++++++++++++++++++++++++++++ src/backend/claude-detector.ts | 19 +++++------ 3 files changed, 95 insertions(+), 9 deletions(-) create mode 100644 docs/SPEC-3-smoke-checklist.md create mode 100644 scripts/spec-3-smoke.mts diff --git a/docs/SPEC-3-smoke-checklist.md b/docs/SPEC-3-smoke-checklist.md new file mode 100644 index 0000000..039a5c2 --- /dev/null +++ b/docs/SPEC-3-smoke-checklist.md @@ -0,0 +1,26 @@ +# SPEC-3 smoke checklist (real-pi, term-driven) + +Rows that need no `claude` call are run via `term` inside a real pi session; rows 2-4 are the script. + +## How to run +- Script (rows 2-4): `node --import tsx scripts/spec-3-smoke.mts` (skips CC rows if claude absent) +- Term rows (1/5/6/7): spawn pi in `~/local-dev/getpipher/armory-fleet`, drive via `term` + +## Rows +| # | Action | Expected | +|---|---|---| +| 1 | extension loads with `claude` absent | `/fleet` Backends view shows `claude: ✗ (not installed)`; `pi: ✓` | +| 2 | `subagent(general-purpose, "reply OK")` (pi) | run completes; armory chip `t✓ m✓ v✓` | +| 3 | `subagent(general-purpose-cc, "reply OK")` (claude, if available) | run completes via `claude -p`; `backendSessionId` set; chip `t✓ m✓ v~` | +| 4 | re-spawn `general-purpose-cc` same `sessionKey` | `--resume ` passed; CC replays history | +| 5 | `backend: invalid` profile in `.pi/agents/` | load warning surfaced; profile excluded from registry | +| 6 | `claude` schema drift (point FLEET_CLAUDE_BIN at a fake) | Backends view shows `schema ✗`; spawn fails fast with actionable error | +| 7 | Backends view `r:Refresh` + `i:Info` | refresh notifies "restart pi to re-detect"; info shows flag matrix + hook mechanism notes | + +## How to inspect the CC invocation +- The `i:Info` pane on the `claude` backend row shows the flag-support matrix probed at init. +- Set `DEBUG=fleet:cc` (or equivalent) to log the composed `claude -p` args + the NDJSON events received. + +## Pass bar +- Rows 1, 5, 6, 7 pass (term-driven, no CC call). +- Rows 2-4 pass when `claude` is installed; skipped (exit 0) otherwise. \ No newline at end of file diff --git a/scripts/spec-3-smoke.mts b/scripts/spec-3-smoke.mts new file mode 100644 index 0000000..a7a0cab --- /dev/null +++ b/scripts/spec-3-smoke.mts @@ -0,0 +1,59 @@ +// scripts/spec-3-smoke.mts — SPEC-3 full-run smoke (rows 2-4). +// Exercises the REAL CC backend (spawn a real `claude -p`) when claude is installed; skips cleanly otherwise. +// Run: node --import tsx scripts/spec-3-smoke.mts +import { spawnSubagent } from "../src/engine/spawnSubagent.ts"; +import { RunRegistry } from "../src/engine/run-registry.ts"; +import { createSingleSlotLock } from "../src/engine/concurrency-lock.ts"; +import { ArmoryTodoAdapter } from "../src/todo-sync/adapter.ts"; +import { ArmoryMemoryAdapter } from "../src/memory-hydrate/adapter.ts"; +import { BackendRegistry, PI_HOOK_PARITY, CLAUDE_HOOK_PARITY } from "../src/backend/port.ts"; +import { detectClaude } from "../src/backend/claude-detector.ts"; +import { createClaudeChildFactory } from "../src/backend/claude-factory.ts"; +import { ResumeStore } from "../src/backend/resume-store.ts"; +import { ModelRuntime } from "@earendil-works/pi-coding-agent"; +import { createChildSessionFactory } from "../src/index.ts"; +import type { AgentDef } from "../src/registry/frontmatter.ts"; + +let pass = 0, fail = 0; +function check(name: string, cond: boolean, detail = ""): void { + if (cond) { console.log(` ✔ ${name}`); pass++; } + else { console.log(` ✖ ${name} ${detail}`); fail++; } +} + +const resumeStore = new ResumeStore(); +const claudeInfo = await detectClaude(); +if (!claudeInfo?.schemaOk) { + console.log("⏭ claude not available (not installed or schema drift) — skipping CC rows.

Added a test that empties PATH to force the ENOENT path. - ClaudeChildSession.prompt: guard against null proc.stdin (would hang the engine's await session.prompt() forever); throws an actionable error instead. Other observations noted as acceptable-for-v0.3 (not fixed): CC 'result' with is_error:true maps to turn_end per spec §4.2 (auth failure surfaces as finalText); positional-task + stdin double-pass is a harmless smell the smoke verifies works. --- src/backend/claude-detector.ts | 3 ++- src/backend/claude-session.ts | 3 ++- test/claude-detector.test.mts | 11 +++++++++++ 3 files changed, 15 insertions(+), 2 deletions(-) diff --git a/src/backend/claude-detector.ts b/src/backend/claude-detector.ts index a5c7b50..cc36652 100644 --- a/src/backend/claude-detector.ts +++ b/src/backend/claude-detector.ts @@ -19,7 +19,8 @@ function run(bin: string, args: string[], env?: NodeJS.ProcessEnv): Promise<{ st child.stdout?.on("data", (d) => { stdout += d.toString(); }); child.stderr?.on("data", (d) => { stderr += d.toString(); }); child.on("close", (code) => resolve({ stdout, stderr, code })); - child.on("error", () => resolve({ stdout: "", stderr: "", code: null })); + // Capture the spawn error message into stderr so the caller can detect ENOENT (binary missing). + child.on("error", (err) => resolve({ stdout: "", stderr: err.message, code: null })); }); } diff --git a/src/backend/claude-session.ts b/src/backend/claude-session.ts index de40021..6b8e57e 100644 --- a/src/backend/claude-session.ts +++ b/src/backend/claude-session.ts @@ -38,10 +38,11 @@ export class ClaudeChildSession implements ChildSession { async prompt(text: string): Promise { if (this.disposed) throw new Error("session disposed"); + if (!this.proc.stdin) throw new Error("claude child has no stdin pipe"); const msg = JSON.stringify({ type: "user", message: { role: "user", content: [{ type: "text", text }] } }) + "\n"; return new Promise((resolve) => { this.turnResolve = resolve; - this.proc.stdin?.write(msg, () => { /* fire-and-forget; resolved on turn_end/close */ }); + this.proc.stdin!.write(msg, () => { /* fire-and-forget; resolved on turn_end/close */ }); }); } diff --git a/test/claude-detector.test.mts b/test/claude-detector.test.mts index 3ab0219..855e5d6 100644 --- a/test/claude-detector.test.mts +++ b/test/claude-detector.test.mts @@ -21,6 +21,17 @@ test("returns null when the binary is missing", async () => { strictEqual(info, null); }); +test("returns null when the default `claude` is not on PATH (ENOENT captured)", async () => { + const origPath = process.env.PATH; + process.env.PATH = ""; // force spawn ENOENT for the default bin + try { + const info = await detectClaude("claude"); + strictEqual(info, null); + } finally { + process.env.PATH = origPath; + } +}); + test("schema drift (init missing session_id) → schemaOk false + note", async () => { const info = await detectClaude(fakeBin, { schemaProbeArg: "init-drift" }); ok(info);
