Description

The emergency condense in handleContextWindowExceededError copied the automatic path's result handling instead of sharing it, and the copy had drifted. This PR fixes the two defects from the issue and one of the argument divergences.

condenseId on the event. The emergency condense_context event had no condenseId, so MessageManager's id-based rewind cleanup could never remove the emergency summary. Deleting the condense row cut the history after the summary (summary at last message + 1, row emitted later), which left the summary in place.
Errors surfaced. An error returned by manageContext was dropped. It now shows as condense_context_error, as on the automatic path.
Shared reporter. Both paths now report through one reportContextManagementResult helper (error row, then the condense event or the truncation row), so the fields can't drift apart again. For the automatic path this is a pure move with no behaviour change.
Same condense settings (divergence 3). The emergency manageContext call now also passes the custom CONDENSE prompt, filesReadByRoo, cwd, and rooIgnoreController, so a recovery summary is built like an automatic one.

The manual condenseContext() path is unchanged. It calls summarizeConversation directly, returns early on error, and already emitted condenseId and the error row.

Not included: divergence 4, where a profile threshold can override the forced 75% during recovery. It changes recovery behaviour, so it belongs in a separate follow-up (Open question 2 in the issue).

Test Procedure

New regression tests:

Task.spec.ts → emergency condense reporting (#1769). These call the real handleContextWindowExceededError, not a mock:
- A successful condense emits contextCondense.condenseId equal to the summary's id, and summarizes with the custom prompt and cwd.
- A failed condense emits condense_context_error, followed by the fallback sliding_window_truncation row.
- Both tests fail against the original Task.ts.
message-manager/index.spec.ts: deleting the emergency condense row removes the summary when the event carries a condenseId. A second case shows the summary survives when the id is missing, which was the pre-fix behaviour.

Commands:

cd src
npx vitest run core/task/__tests__/Task.spec.ts core/message-manager core/condense core/context-management
pnpm exec eslint --max-warnings=0 core/task/Task.ts core/task/__tests__/Task.spec.ts core/message-manager/index.spec.ts

Results: 378 tests passed; type checking and ESLint passed (also via the commit hook). ESLint suppression counts are unchanged.

Additional Notes

Follow-up candidate from the issue's open questions: let recovery take precedence over profileThresholds (an empty threshold map on the emergency call, or a forceThreshold flag on manageContext). With a profile threshold of 95%, today's emergency call can return the history unchanged with no event at all.

🤖 Generated with Claude Code

The emergency condense in handleContextWindowExceededError duplicated the automatic path's result handling and had diverged: - Its condense_context event carried no condenseId, so rewind cleanup could not remove the emergency summary; deleting the condense row cut after the summary and left it in place. - A condense error returned by manageContext was dropped instead of being shown as condense_context_error. - It ignored the custom CONDENSE prompt and did not pass filesReadByRoo, cwd, or rooIgnoreController. Both paths now report through one reportContextManagementResult helper, and the emergency call passes the same condense settings. The profile threshold overriding the forced 75% is left for a follow-up. Fixes Zoo-Code-Org#1769 Co-Authored-By: Claude Opus 5.5 (1M context) <[email protected]>

Summary

Summary by CodeRabbit

Bug Fixes
- Improved recovery when a conversation reaches its context limit. Summaries now use the configured condensation prompt and relevant workspace context.
- Rewinding a conversation removes a summary when its event is linked to it; summaries remain when the event has no link.
- Context-management errors are reported before recovery falls back to truncating older conversation context. The fallback now reports the truncation and the amount of removed context.

Task now uses shared reporting for context-management results. Emergency recovery passes task context options to manageContext. Tests cover condensation IDs, error reporting, and rewind behavior.

Changes: Context management

Layer / File(s)	Summary
Emergency and automatic context management reporting `src/core/task/Task.ts`, `src/core/task/__tests__/Task.spec.ts`, `src/core/message-manager/index.spec.ts`	`Task` reports context-management errors, condensation events with `condenseId`, and sliding-window truncation through a shared method. Emergency requests include the custom condensing prompt, files-read context, working directory, and ignore controller. Tests cover success and failure events and verify rewind behavior for matching and missing condensation IDs.

Merge Risk: Low · up to 91304

The reporting change has a bounded cancellation concern: emergency recovery can still truncate conversation history after cancellation. This behavior predates the change, but the added await slightly extends the exposure. Mergeable with owner awareness and a cancellation follow-up.

Explanation

The description covers the linked issue, implementation details, test procedure, regression coverage, scope, and checklist. It omits the Get in Touch section and some checklist items, but it is otherwise complete and relevant.

Full details: Linked Issues check

Explanation

Issue #1769 requirements are met. Task.reportContextManagementResult emits condense_context_error before fallback truncation and includes ContextManagementResult.condenseId in contextCondense. Emergency recovery uses this reporter and passes the custom prompt, file context, cwd, and ignore controller. Regression tests cover the real emergency handler, matching IDs, error reporting, and rewind cleanup. Profile-threshold behavior remains explicitly excluded by the issue and PR scope.

Full details: Out of Scope Changes check

Explanation

The changes stay within issue #1769. The shared reporter removes duplicated reporting logic between the automatic and emergency paths. The emergency settings align its condense result with the automatic path. The added tests verify emergency reporting and rewind cleanup. No unrelated product behavior is identified.

Full details: Security Boundaries

Explanation

No changed path meets the security failure conditions. The emergency path passes filesReadByRoo, cwd, and rooIgnoreController through manageContext to folded-file generation, and file parsing checks rooIgnoreController.validateAccess before reading content. The shared reporter only emits context-management events. It does not execute input, invoke tools, or bypass approval or allowlist controls. The custom prompt is passed as model prompt data and is not executed.

Full details: Persistence Integrity

Explanation

No changed persistence path meets the failure condition. In both emergency and automatic paths, the changed code awaits overwriteApiConversationHistory before reporting. overwriteApiConversationHistory awaits saveApiConversationHistory, and reportContextManagementResult awaits each say call. say adds the event through addToClineMessages, which awaits saveClineMessages. The shared reporter only moves existing automatic-path logic and adds the emergency result fields; it does not introduce an unawaited write, non-atomic write, missing rollback, or missing persisted default propagation.

Full details: Lifecycle Resource Cleanup

Explanation

No changed lifecycle path can be shown to leak a resource or duplicate work. The PR adds a result-reporting helper that only awaits existing say calls, and it moves the automatic reporting code without changing its behavior. The emergency path adds data reads and passes the existing rooIgnoreController into manageContext; it does not create listeners, watchers, timers, providers, or tasks. Existing cancellation and disposal still abort requests and dispose rooIgnoreController and fileContextTracker.

Full details: Regression Evidence

Explanation

The prior regression gap remains. Task.handleContextWindowExceededError now obtains filesReadByRoo and forwards both filesReadByRoo and rooIgnoreController to manageContext (src/core/task/Task.ts:5559,5578-5580). The focused emergency success test only asserts customCondensingPrompt and cwd (src/core/task/__tests__/Task.spec.ts:2577-2595). It does not configure a non-empty getFilesReadByRooSafely result or assert either changed option. A regression in this emergency Task-level wiring would pass the added tests. Lower-level context-management tests do not cover this caller wiring.

Resolution

Extend the emergency-condense success test to return a non-empty file list from getFilesReadByRooSafely and assert that summarizeConversation receives that list, task.cwd, and the exact task.rooIgnoreController. Add an unset or collector-failure case if emergency recovery must preserve undefined file context.
