feat(codex): richer notifications (question tool, subagent opt-in, error statuses) - #139
Conversation
… and error heuristics - PreToolUse hook (matcher ^request_user_input$) delivers real Question notifications with the question text projected through an allowlist (question/header only; options, ids, and secret fields never leave the payload); turn+call-scoped dedup, exempt from the question cooldown and content dedup since the session blocks until answered - SubagentStop delivery for Codex behind the existing opt-in semantics (notifyOnSubagentStop + suppressForSubagents), classified from the subagent's final message - short failure messages map to api_error/api_error_overloaded/ session_limit_reached via a bounded pattern heuristic (documented MVP: failure phrasings only, capped length to avoid false positives on summaries) - classification sits behind the CodexTurnEnricher port with a pure heuristic default, so an app-server-backed analyzer can be injected later without touching the pipeline (DIP seam) - hooks-codex.json gains the PreToolUse entry before the first-release identity freeze; golden test covers the matcher form - sdk bumped to the CodexPreToolUse-capable commit

Without a hooks-codex.json entry the host never invokes the binary on SubagentStop and notifyOnSubagentStop would be dead configuration. An opted-out run costs one async process that exits at the config check. Golden identity test extended to the four-handler contract.
- gate the Ghostty terminal capture to the Claude product: it persists
session state under the RAW session id, and Codex state must only use
hashed identities (the codex question path made this reachable)
- exempt codex SubagentStop from the session-wide content dedup so
parallel subagents finishing with an identical final message cannot
collapse into one notification (regression test added)
- error heuristic: every pattern is now a self-anchored failure phrase
('rate limit reached', not 'rate limit'), so short task summaries like
'Fixed the rate limit bug.' stay task_complete; the length cap counts
runes instead of bytes so non-ASCII scripts get the same budget
- go mod tidy drops the superseded sdk pseudo-pin

508-511: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winDo not use the session content lock for content-dedup-exempt Codex events.
Two Codex subagents in the same session can reach this branch concurrently. The first hook holds the session-scoped content lock. The second hook returns without delivery. This defeats the required parallel-subagent behavior even though lines 535-536 skip content comparison.

| - **Codex CLI support (initial)** - the same Go binary now handles OpenAI Codex CLI hooks: `Stop` (turn completion, classified from the final assistant message) and `PermissionRequest` (new `permission_request` status with sound, webhook colors, and Focus Mode break-through). Ships as a native Codex plugin (`.codex-plugin/plugin.json` + `hooks/hooks-codex.json`) with dedicated launchers `bin/codex-hook-wrapper.sh`/`.cmd`.

Known limitations: `PermissionRequest` cannot fire when Codex never asks for approval (bypass/never modes), and Windows support for the Codex route is not declared until proven. | |||

Remove the stale SubagentStop limitation.
The earlier Unreleased bullet on Line 11 still says Codex SubagentStop is decoded but not delivered yet, while the new entry documents opt-in delivery. Update or merge the earlier bullet so the Unreleased notes do not contradict the implementation.

Include SubagentStop in the manifest description.
The manifest now declares a SubagentStop hook, but the description lists only Stop, PermissionRequest, and question events. Update the description so the plugin metadata matches the configured events.

Describe the notification boundary precisely.
internal/hooks/codex_source.go retains the complete raw event and ToolInput. The integration test proves only that option details, IDs, and secret fields are absent from the notification message. Replace “never leave the payload” with “are not included in the notification message” so the documentation matches the implementation.

Stacked on #138 (base branch feat/codex-runtime; retarget to main after #138 merges).
What
Stage 1 of richer Codex notifications, per the researched design:
Known limitation
request_user_input is mode-gated in Codex (Plan mode) and the live firing of the PreToolUse hook for it has not been proven in an interactive TUI session yet - the matcher is safe either way (worst case it never fires; a non-question tool is skipped by policy, covered by tests).
Testing
Full go test ./... green except the known pre-existing macOS-environment notifier failure (fails on clean main). New coverage: question projection incl. secret-field non-leak, non-question tool skip, cross-turn question repeats, subagent opt-in matrix (default/suppression/enabled), error heuristic table (incl. false-positive guards), PreToolUse through the real SDK, CLI containment for the new event.
Integration and release status
SDK 777genius/universal-agent-plugins#173 and planning #137 are merged. Integrate #138, then #139, then #140. Release qualification is tracked in #141.
The product retains the reviewed SDK pseudo-version; its SDK subtree is identical to merged SDK main. Draft sdk/v1.2.0 exists, but publishing its public module tag requires separate owner approval. The tag is not a prerequisite for merging this pinned product code.
The supported initial Codex path is the shared installer with CN_PRODUCT=codex followed by setup-codex from #140, then trust review in /hooks. Native plugin hook support is documented by current Codex; the earlier claim that Codex categorically ignores plugin hooks was incorrect. Native marketplace installation is not claimed as qualified by this PR chain.
#140 contains follow-up compatibility fixes and the end-to-end qualification evidence. Product v1.42.0 is not published. Question-tool firing in the interactive TUI and visible desktop/audio behavior remain outside the automated evidence.
