From c067b0fc063b4a340a1f7f9bf8a33a81189dde1a Mon Sep 17 00:00:00 2001 From: YeonGyu-Kim Date: Sat, 16 May 2026 00:49:03 +0900 Subject: [PATCH 01/29] refactor(plugin-entry): move createPluginModule to testing module createPluginModule and PluginModuleDeps were exposed at package entry as a test seam. Their export creates accidental public TS API obligations for internal manager/tool/hook constructor types. Move to src/testing/create-plugin-module.ts so only tests reach them.

Per semver, adding public exports mandates a MINOR bump from 4.1.x. No public API removals or breaking signature changes, so this is NOT MAJOR.

Stalled upstream responses no longer hold the reservation forever. BLOCKER-2 (post-dispatch failure released too early): collapse the holdReservationAfterDispatch flag into a dispatchAttempted state so the post-dispatch hold runs in the finally block regardless of whether promptAsync resolved or threw. AGENTS.md's documented race window where promptAsync 'returns before durably accepted, later failures arrive as session.error' is now covered. HIGH-6 (sync/async protocol duplicated): extract dispatchAfterSessionIdle internal runner. promptAsyncAfterSessionIdle and promptAfterSessionIdle become thin wrappers passing client.session.promptAsync vs prompt as the dispatch callback. Future reservation semantics fixes apply once. HIGH-7 (releasePromptAsyncReservation prefix foot-gun, partial): tighten reservationSourceMatches to require prefix strings to end in ':' so release cannot accidentally free reservations whose source merely starts with the same identifier characters. Symbol token verification is still internal-only as the audit invariant prevents external callers from bypassing the gate.

direct call (existing): client.session.promptAsync(...) - property access reference: const x = client.session.promptAsync - bracket access: client['session']['promptAsync'] - optional chaining: client.session?.promptAsync - type cast aliasing: (client.session as { promptAsync }).promptAsync - destructuring: const { promptAsync } = client.session RAW_PROMPT_ALLOWLIST captures two legitimate callers that route through the gate but reference promptAsync as a property value: - src/plugin/event.ts wires a client facade for team-idle-wake-hint - src/hooks/session-recovery/recover-unavailable-tool.ts guards capability before dispatching through promptAsyncAfterSessionIdle.

Takes dependency-injected client, directory, and an enqueueNotificationForParent callback, so the manager can delegate parent-wake state to a narrow API. This commit only introduces the new module; wiring manager.ts to use it is a follow-up commit so the refactor stays atomic (HIGH-9 step 1 of 2).

window regardless of whether the dispatch threw), the synchronous retry path inside promptSyncWithModelSuggestionRetry hit 'reserved' on its own second attempt because the first attempt's post-dispatch hold was still active. The first attempt's failure is ProviderModelNotFoundError, which is a synchronous SDK rejection - the prompt never reached the server, so there is no durable session state worth protecting from a duplicate injection.

Each route can be correct in +isolation and still collide with another route in the same process. -Without a shared gate, two routes can dispatch the same internal prompt into the -same parent session. - -OpenCode also exposes a subtle durability gap. - -`session.promptAsync` can return before the prompt is durably accepted by the -target session. - -A later `session.error` event can still arrive for the same attempt. - -That means a route can think it finished while another hook still sees the -session as eligible for recovery. - -The old pattern was unsafe: - -```ts -await client.session.promptAsync({ - path: { id: sessionID }, - body: { text: message }, -}) -``` - -The unsafe properties were: - -1. No per-session reservation before dispatch. -2. No shared active-session check. -3. No post-dispatch hold for late failures. -4. No timeout around a hung dispatch. -5. No central log trail for skipped or failed dispatches. -6. No static audit that could block new raw prompt routes. - -Local guards inside each feature were not enough. - -Different hooks can run in the same process and see different snapshots of -session state. - -They need one shared reservation map keyed by session ID. - -The root `AGENTS.md` now states the invariant: - -```text -Treat every session.prompt / session.promptAsync call as a write to shared -session state.

Every other route must use the shared gate. ## Decision -All production internal message injection must go through -`src/shared/prompt-async-gate.ts`. +Create `src/shared/prompt-async-gate.ts` as the single production owner of raw +OpenCode prompt dispatch. -The module exports two gate functions: +The gate coordinates callers with a module-global reservation map: ```ts -export async function promptAsyncAfterSessionIdle(args: { - client: PromptAsyncClient - sessionID: string - input: TInput - source: string - settleMs?: number - postDispatchHoldMs?: number - dispatchTimeoutMs?: number - checkStatus?: boolean -}): Promise - -export async function promptAfterSessionIdle(args: { - client: PromptClient - sessionID: string - input: TInput - source: string - settleMs?: number - postDispatchHoldMs?: number - dispatchTimeoutMs?: number - checkStatus?: boolean -}): Promise +const reservations = new Map() ``` -The gate returns a discriminated result instead of throwing for expected races: +The map is keyed by `sessionID`. A reservation records the source that claimed +the session, an expiration time, and a `Symbol(source)` token. The token gives +each reservation identity beyond its text source. -```ts -export type PromptAsyncGateResult = - | { status: "dispatched"; response: unknown } - | { status: "active" } - | { status: "reserved"; reservedBy: string } - | { status: "unavailable" } - | { status: "failed"; error: unknown } -``` - -Callers must treat `active` and `reserved` as successful suppression. - -They mean another actor owns the session or the user is already active. - -They are not retry signals by default. - -Every call must provide a stable `source` string. - -The source identifies the route that reserved the session. - -Recommended source format: +Every caller supplies a stable `source` string such as: ```ts const source = `background-agent:${taskID}` ``` -The reservation flow is: +The shared flow is: 1. Prune expired reservations. -2. Reject if the session already has an active reservation. -3. Reserve the session before waiting or dispatching. -4. Wait for idle settle time. -5. Check current session status unless the caller opted out for a proven reason. -6. Dispatch through `session.promptAsync` or `session.prompt`. -7. Keep a short post-dispatch hold after an attempted dispatch. -8. Release only after the hold expires or through an intentional recovery path. +2. Reserve the session before waiting or dispatching. +3. Wait for the idle settle period. +4. Poll session activity unless the route has a proven opt-out. +5. Dispatch through the selected OpenCode prompt API. +6. Keep the reservation during the post-dispatch hold. +7. Release after the hold or through an explicit recovery path. -The default timing constants are part of the decision: +The reservation is taken before the activity poll so that two hooks cannot both +enter the poll-dispatch window. + +The default post-dispatch hold is exported as: ```ts export const DEFAULT_PROMPT_ASYNC_POST_DISPATCH_HOLD_MS = 250 +``` + +`postDispatchHoldMs` defaults to 250 ms. The gate holds the reservation briefly +after the dispatch attempt even when dispatch throws synchronously or returns a +failed result. This closes the AGENTS.md hazard where `promptAsync` returns +before durable acceptance and a late OpenCode error races with retry logic. + +The default dispatch timeout is 30 seconds: + +```ts export const DEFAULT_PROMPT_DISPATCH_TIMEOUT_MS = 30_000 ``` -The post-dispatch hold is required because `promptAsync` returning does not prove -that all related OpenCode events have drained. +`dispatchTimeoutMs` wraps the underlying `session.promptAsync` or +`session.prompt` call with `Promise.race`. A hung OpenCode API call must fail +closed instead of holding a reservation forever. -The dispatch timeout is required because a stuck OpenCode API call must not hold -the reservation forever. - -The timeout is a circuit breaker, not a synchronization primitive. - -Callers must not set `postDispatchHoldMs: 0`. - -The static audit rejects that pattern. - -If a caller needs custom behavior, it must add a route-specific regression test -that proves duplicate dispatch cannot occur. - -The gate owns the raw prompt calls: +Both public gate helpers delegate to one internal runner: ```ts -const promptAsync = client.session?.promptAsync - -if (typeof promptAsync !== "function") { - return { status: "unavailable" } -} - -return dispatchAfterSessionIdle({ - sessionName: "promptAsync", - client, - sessionID, - input, - source, - settleMs, - postDispatchHoldMs, - dispatchTimeoutMs, - checkStatus: args.checkStatus !== false, - dispatch: (dispatchInput) => promptAsync(dispatchInput), -}) +dispatchAfterSessionIdle(args) ``` -Production code outside this module must not access these APIs directly: +`promptAsyncAfterSessionIdle` passes a `session.promptAsync` dispatcher. +`promptAfterSessionIdle` passes a `session.prompt` dispatcher. Sharing the +runner keeps reservation, hold, timeout, logging, and active-session behavior +identical for async and sync prompt routes. + +The public gate result is a discriminated union. Callers must treat `active` +and `reserved` as successful suppression, not automatic retry signals. A route +that changed optimistic task or loop state before dispatch owns restoring that +state when the gate returns `failed`, `unavailable`, or a skipped status that +requires rollback. + +The gate exposes `releasePromptAsyncReservation` for intentional recovery +paths. Prefix release is deliberately tight: ```ts -client.session.prompt(...) -client.session.promptAsync(...) -client["session"]["promptAsync"](...) -const { promptAsync } = client.session -Reflect.apply(client.session.promptAsync, client.session, [input]) -``` - -Type guards may check that `promptAsync` exists when the eventual dispatch still -routes through the shared gate. - -The allowlist in the audit must stay small and justified. - -The gate also exposes reservation release helpers for intentional recovery: - -```ts -releasePromptAsyncReservation(sessionID, { - reservedBy: "model-suggestion-retry", -}) - releasePromptAsyncReservation(sessionID, { reservedByPrefix: "runtime-fallback:", }) ``` -Prefix release is allowed only for prefixes that end with `:`. +`reservedByPrefix` must end in `:`. This prevents broad releases such as +`runtime` matching unrelated sources. Exact source release remains available +for callers that know the full reservation source. -This prevents broad accidental releases such as `runtime` matching unrelated -sources. - -Release helpers exist for rollback and retry flows. - -They must not be used as a normal cleanup path after dispatch. +Raw prompt calls outside the gate are blocked by +`src/shared/prompt-async-route-audit.test.ts`. The audit uses the TypeScript +Compiler API rather than regex so it catches destructuring, bracket access, +optional chaining, and aliased or cast access patterns. ## Consequences -Positive consequences: +### Positive -- Duplicate internal dispatches collapse to one reservation winner. -- Late `session.error` events no longer trigger immediate duplicate retries. -- Internal message routes share logging and result semantics. -- Tests can reason about a single gate instead of many ad hoc guards. -- New raw prompt routes are blocked by a static audit. -- Retry flows can release only their own reservation source. -- Hung dispatches fail closed through a timeout. +- Duplicate internal prompt injection now has one reservation winner per + session. +- The post-dispatch hold closes the AGENTS.md "returns before durably + accepted" hazard even when dispatch errors synchronously. +- Dispatch timeout prevents a stuck OpenCode call from holding the gate forever. +- 13+ internal hook callers share one result model and one safety primitive. +- The AST-based audit from HIGH-5 catches more bypass shapes than the prior + regex audit. +- Route-specific tests can focus on route behavior while the shared gate tests + reservation semantics. -Negative consequences: +### Negative -- Internal prompt injection has a small default latency from idle settling. -- A post-dispatch hold can delay a legitimate retry by 250 ms. -- Callers must handle `PromptAsyncGateResult` instead of assuming dispatch. -- Tests that mock session APIs may need to model reservation state. -- Any new route must add route-specific duplicate-injection coverage. +- Caller-side retry logic that releases and retries must call + `releasePromptAsyncReservation` explicitly when the original prompt did not + durably reach the server. `src/shared/model-suggestion-retry.ts` is the + reference case. +- 13+ wiring sites each need to be conscious of the gate result. Treating + `reserved` as a failure can create noisy retries. +- A valid retry can be delayed by the default 250 ms post-dispatch hold. +- The reservation map is process-local. It protects OMO hooks in the current + plugin process, not every possible OpenCode process. -Operational consequences: +### Migration -- CI green is not enough for race fixes tied to issue 4012. -- Maintainers must re-run the documented reproducer against the fix commit. -- Logs containing `[prompt-async-gate]` are the first place to inspect when a - wake, retry, or recovery message does not appear. +Existing `session.prompt` and `session.promptAsync` callers must route through +`promptAfterSessionIdle` or `promptAsyncAfterSessionIdle`. -Testing consequences: +The AST-based audit fails CI if a raw prompt call is added without an allowlist +entry. Any allowlist entry must explain why the raw access is not a dispatch +route or why it is still gate-routed. -- `src/shared/prompt-async-gate.test.ts` covers gate behavior. -- `src/shared/prompt-async-route-audit.test.ts` blocks raw production prompt - routes. -- Route owners must add regression tests for the specific trigger they wire. -- Tests must not rely on sleeping to wait for the post-dispatch hold. +New internal message routes must include duplicate-injection regression tests +for their trigger. Static policy alone is not enough. -Design constraints that remain open: +### Future work -- The reservation map is process-local. -- Cross-process OpenCode sessions still rely on the session API and event stream. -- The gate does not deduplicate different semantic prompts for the same session. -- The gate prevents concurrent injection, not incorrect caller intent. - -Rejected alternatives: - -1. Keep route-local guards. - - This failed because hooks observe the same edge from different modules. - -2. Disable recovery on any recent prompt event. - - This would hide valid recovery paths and lose task state. - -3. Use a global fixed delay after every dispatch. - - A delay without a reservation does not prevent another route from entering. - -4. Treat `promptAsync` success as durable acceptance. - - Issue 4012 showed that later OpenCode errors can still arrive. - -5. Allow raw prompt calls with code review discipline. - - The risk is architectural, so the invariant needs an automated audit. - -Migration rule: - -```ts -const result = await promptAsyncAfterSessionIdle({ - client, - sessionID, - input, - source: "runtime-fallback:retry", -}) - -if (result.status === "failed") { - restoreOptimisticState() -} -``` - -The caller owns any optimistic task or loop state it changed before dispatch. - -If dispatch is skipped, unavailable, or failed, the caller must restore state -when needed. +- Replace prefix-tightened release with full Symbol-token-based release + ownership.

Routes 13+ internal hook callers through reservation-based duplicate-injection prevention. See `docs/reference/prompt-async-gate-rfc.md`. -- Background-agent: extracted `ParentWakeNotifier` module for parent-wake coalescing (preparatory refactor; manager.ts integration in same release). -- First-prompt watchdog for stuck subagents (closes #3952 by way of #4051). -- Subagent quota abort fast-path when no fallback is configured (closes #4006). - -### Fixed - -- prompt-async-gate: add dispatch timeout via `Promise.race`, fix post-dispatch reservation hold on throw, harden prefix release to require `:` suffix (BLOCKER-1, BLOCKER-2, HIGH-6, HIGH-7 partial). -- model-suggestion-retry: release reservation before suggested-model retry attempt (regression caused by post-dispatch hold landing). -- prompt-async-gate tests: remove fixed-time sleep synchronization from the BLOCKER-3 path. The final release branch should keep only event-driven test synchronization for this area. -- session-recovery: schema-compatible synthetic tool results (PR #4053 supersedes #3866). -- tool-pair-validator: schema-compatible synthetic results for background sessions (PR #4032). -- claude-code-hooks: accumulate modifiedInput on allow/deny/ask exit paths (PR #3299 area, multiple commits). -- runtime-fallback: dedupe overlapping continuations, preserve provider-specific retries, classify localized provider errors. -- team-mode: skip tmux layout when opencode server unreachable (closes #3894). -- delegate-task: honor user fallback_models when category primary is unreachable. -- background-agent: detect stalled active sessions, coalesce rapid idle parent notifications, retry transient missing output tasks. -- todo-continuation: remove activity-based stagnation bypass, clean up idle event diagnostics. -- AGENTS.md: strengthened prompt-injection danger warning with root-cause analysis, gate semantics, forbidden patterns, and required tests. +- `createPluginModule` test seam moved out of public API surface to `src/testing/create-plugin-module.ts`. New public exports for the prompt-async-gate primitives: `promptAsyncAfterSessionIdle`, `promptAfterSessionIdle`, `releasePromptAsyncReservation`, `DEFAULT_PROMPT_ASYNC_POST_DISPATCH_HOLD_MS`, `DEFAULT_PROMPT_DISPATCH_TIMEOUT_MS`. +- `ParentWakeNotifier` module (`src/features/background-agent/parent-wake-notifier.ts`) extracted from `BackgroundManager`. Background-agent parent-wake state now lives in its own narrow class with dependency-injected client, directory, and notification enqueue callback. ### Changed -- TypeScript audit: prompt-async-route-audit migrated from regex to TypeScript AST walker, catching destructuring, bracket call, optional chaining, and type-cast aliased bypass patterns (HIGH-5). -- Public surface: `createPluginModule` test seam moved from `src/index.ts` to `src/testing/create-plugin-module.ts` (HIGH-8). Plugin default export `pluginModule` is unchanged. -- CI: removed sharded test runner; now uses plain `bun test` in a single process (test-discipline.md added to enforce no-`setTimeout`-in-tests). -- Background-agent: manager.ts internal parent-wake state delegated to `ParentWakeNotifier` (HIGH-9). +- `prompt-async-gate` now uses a shared internal runner for both sync (`prompt`) and async (`promptAsync`) dispatch wrappers, deduplicating the reserve/settle/check/dispatch/hold/release flow. +- `releasePromptAsyncReservation` accepts `reservedByPrefix` only when the prefix ends in `:` (e.g., `model-fallback:`), preventing accidental release of sibling reservations whose source merely starts with the same identifier characters. +- Version bump from 4.1.2 to 4.2.0. Reason: added public exports for the gate primitives qualify as MINOR per semver. No removals or breaking signature changes. -### Known Issues +### Fixed -- BLOCKER-4: Delegated child-session early-failure fallback (PR #3825 reverted). Delegated subagents that fail on the very first `promptAsync` may not advance to fallback models. See `docs/reference/known-issues.md`. Reland targets v4.2.1. +- `prompt-async-gate`: dispatch timeout via `Promise.race` with a default 30s window. Previously a hung `promptAsync` deadlocked the gate for that sessionID until process restart. (BLOCKER-1) +- `prompt-async-gate`: post-dispatch failure now keeps the reservation hold regardless of whether `promptAsync` resolved or threw. AGENTS.md's documented race window ("returns before durably accepted, later failures arrive as `session.error`") is now covered. (BLOCKER-2) +- `prompt-async-gate.test.ts`: replaced `setTimeout`-based synchronization with event-driven patterns to comply with the new `.sisyphus/rules/test-discipline.md` rule. (BLOCKER-3) +- `model-suggestion-retry`: releases the reservation before the suggested-model retry so the second attempt can dispatch immediately. Without this, BLOCKER-2's post-dispatch hold trapped the retry path. ### Internal -- New `.sisyphus/rules/test-discipline.md` rule: forbids `setTimeout(resolve, N)` and `await sleep(N)` in test bodies unless time itself is the SUT. -- mock.module lifecycle audit test (`src/shared/mock-module-lifecycle-audit.test.ts`) added to catch unpaired mocks (H10). -- Public exports for prompt-async-gate primitives - MINOR semver bump justified. -- If parallel BLOCKER-3, HIGH-9, or BLOCKER-4 follow-up commits land after this entry, update the changelog in the final release commit with their exact hashes. +- `prompt-async-route-audit.test.ts` migrated to TypeScript compiler API for AST-based detection. Catches destructuring, bracket access, optional chaining, and type-cast aliasing bypass patterns. Two existing production callers are documented in `RAW_PROMPT_ALLOWLIST` with justifications: `src/plugin/event.ts` (team-idle-wake-hint client facade) and `src/hooks/session-recovery/recover-unavailable-tool.ts` (capability check before gate-routed dispatch). (HIGH-5) +- New `mock-module-lifecycle-audit.test.ts` enforces cleanup pairing for `mock.module(...)` calls in test files; existing offenders allowlisted with TODO references. (HIGH-10) +- `.sisyphus/rules/test-discipline.md` added in this release window forbidding `setTimeout(resolve, N)` and `await sleep(N)` in test bodies unless time is the SUT. Several CI sharding commits earlier in the window were superseded by removing the sharded runner in favor of the rule. + +### Known Issues + +- **Delegated child-session early-failure fallback (BLOCKER-4)**: PR #3825's `fac90d69f` was reverted by PR #4044 because its own regression test failed on clean root `bun test`. The delegate-task fallback bug for empty session history remains unaddressed in v4.2.0. Reland targets v4.2.1 once the regression test is stabilized against post-#4032 schema and the new gate semantics. See `docs/reference/known-issues.md` for details and workaround. +- **First-prompt watchdog supersession history (L16)**: PR #3952 was superseded by PR #4051 (rebased over #4007/factory refactor with `internallyAbortedSessions` threading). The supersession represents conflict resolution, not a feature pivot. The final watchdog logic shipped via #4051 + `a130fa70d` covers subagent first-prompt silence past 90 seconds with cleanup via session.deleted. + +[4.2.0]: https://github.com/code-yeongyu/oh-my-openagent/compare/v4.1.2...v4.2.0
