feat(context): condense context after idle time - #2340
This PR adds an optional "Idle Condensing" feature to context management. When the user enables it, an active task starts an idle countdown after a model response ends with context above the idle trigger threshold. The countdown condenses the context when it expires, even when the context is only partially full.
A large fraction of the 40+ edited files are just adding new test UI cases for the config section and how user messages queue up while the condense is in progress. The actual code change is not too crazy.
How it works:
Three new settings live with the existing context management settings: "Idle Condensing Enabled" (default off), "Idle Condensing Trigger Threshold" (a percentage, clamped to the existing condense threshold), and "Idle time" (seconds, minimum zero). Per-model profile overrides mirror the existing condensing settings.
In Task, maybeStartIdleCondenseTimer() arms the countdown after each model response, and evaluateIdleCondense() re-checks every gate (enabled, active task, threshold, no condense in flight) both at arm time and at expiry. Typing in the chat box resets the countdown. Sending a new prompt cancels it. Task disposal cancels it.
On expiry the timer calls the same code path as the manual "Intelligently condense context" button: condenseContextWithLease(). Before it runs, the backend posts condenseTaskContextStarted; in a finally block it posts condenseTaskContextResponse. The chat therefore shows the same "Condensing context..." row with its busy icon that a manual condense shows, while the chat box keeps the normal press-to-send state. Messages sent during a condense queue and drain through the existing processQueuedMessages() path.
Pre-Submission Checklist
Issue Linked: This PR is linked to an approved GitHub Issue (see "Related GitHub Issue" above).
Scope: My changes are focused on the linked issue (one major feature/fix per PR).
Self-Review: I reviewed my own code with care.
Writing Style: The PR title and description use Simplified Technical English (ASD-STE100): short sentences, plain words, active voice, one idea per sentence, no contractions.
Testing: New and/or updated tests have been added to cover my changes (if applicable).
Test Helpers (test changes only): Shared test helpers (src/test-utils/, @/utils/test-utils) are used only for mechanical duplication; test intent and scenario-specific mocks remain visible.
Visual Snapshot (UI changes only): If a user would notice this change at a glance (layout, theme tokens, brand elements, empty/error states), I added or updated a *.visual.tsx snapshot in webview-ui/. See webview-ui/AGENTS.md → "When a UI change needs a snapshot".
Documentation Impact: I checked if my changes need documentation updates (see "Documentation Updates" section below).
The in-chat condense cue reuses the existing "Condensing context..." row that a manual condense already renders, so the chat surface is unchanged.
Documentation Updates
Yes, documentation updates are required. The user-facing docs should describe the three new settings ("Idle Condensing Enabled", "Idle Condensing Trigger Threshold", "Idle time"), the per-model overrides, and the behavior rule that a condense as the last action suppresses the next idle condense.
Add an optional Idle Condensing feature. When enabled, the task starts an idle countdown after a model response ends with context above the idle threshold. Typing resets the countdown. A new prompt cancels it. When the countdown expires, the task condenses the context through the same code path as the manual condense button, and the chat shows the same in-progress cue.
Settings: Idle Condensing Enabled (default off), Idle Condensing Trigger Threshold (percent, clamped to the condense threshold), Idle time (seconds, minimum zero). Per-model profile overrides mirror the existing condensing settings.

Summary
Summary by CodeRabbit
New Features
Context can be condensed automatically after a configurable idle period and usage threshold. This feature is off by default; the default threshold is 50% and the idle period is 180 seconds.
Configure idle-condensing thresholds and delays globally or per model profile. Profile settings can inherit global values, and idle thresholds are capped by the applicable automatic-condensing threshold.
Editing the prompt resets the idle countdown. A zero-second delay triggers condensation as soon as the model is idle.
Messages sent while context is being condensed are queued and handled afterward.
Idle-condensing settings are available in multiple languages.
This change adds configurable idle-triggered context condensation, including global and profile-specific thresholds and delays. The task schedules condensation while eligible asks await a response, coordinates history replacement with ask handling, and reevaluates eligibility after relevant setting changes. Chat edits reset the timer, and messages sent during condensation are queued.

Adds idle-condensing settings and extension-state fields. State projections provide disabled, 50%, 180-second, and empty-map defaults. Settings updates validate and normalize values, then reevaluate the active task after relevant saved changes.
Task scheduling and condense coordination src/core/task/Task.ts, src/core/task/__tests__/*, src/core/context-management/__tests__/context-management.spec.ts, src/core/webview/__tests__/ClineProvider.spec.ts
Adds profile-aware idle eligibility, timer scheduling, cancellation and retry handling, and checks for stale evaluations. Condensation uses a serialized lease and history barrier. Results include condensation status and token counts. Tests cover task lifecycle, ask handling, and condense outcomes.

Explanation
Issue #2339 requests idle context condensing below the normal threshold after a configurable idle delay. The PR adds enablement, global and per-profile thresholds and delays, caps idle thresholds at the effective normal threshold, and arms and rechecks eligibility around task activity. Task uses the shared condense path and suppresses repeat idle condensing after a condense. Settings and task tests cover configuration, timer lifecycle, suppression, and queued-message handling.

Explanation
The settings UI, profile-aware resolution, timer lifecycle, condense lease and history barrier, message queue handling, localization, and tests support the idle-condensing behavior in issue #2339. No unrelated change is established by the whole-PR summary.
Full details: Security Boundaries
Explanation
No concrete security boundary violation was found in the changed paths. Idle condensing is opt-in and reuses the existing summarization path. Pending tool and command approvals are excluded from idle eligibility, and the queue drain retains protected-ask and blanket-deny checks. The chat queue change also removes message text and image data from its diagnostic log.
Full details: Persistence Integrity
Explanation
The prior failure remains unresolved. The new idle-condense path calls condenseContextWithLease in src/core/task/Task.ts:3023. If the history write fails, saveApiConversationHistory returns false, but overwriteApiConversationHistory ignores it (1636–1639, 1728–1740). The condense still records success and returns condensed: true (3463–3485). If the task restarts before a successful save, resume loads the old history and loses the summary (3910–3925).
Resolution
Propagate the history-save failure to the condense path. Retry the write or restore the previous history, and report failure until the replacement is durable.
Full details: Regression Evidence
Explanation
Two programmatic edits lack focused reset coverage. ChatTextArea.tsx:222,594 sends idleCondenseReset after text insertion and mention deletion. The tests at ChatTextArea.spec.tsx:1401-1412,1424-1439 check only the input value. Removing either reset would not fail those tests, allowing the countdown to expire after an edit.
Resolution
Add component tests that assert idleCondenseReset after insertTextIntoTextarea and programmatic mention deletion.
Full details: Lifecycle Resource Cleanup
Explanation
The prior failure remains unresolved. Task.ts:3015-3044 starts an idle summary with an abort signal, and disposal aborts it at Task.ts:4406-4410. However, poe.ts:141-150 does not pass that signal to streamText. If Poe stalls, the summary stream and the new condense lease can remain pending after disposal (condense/index.ts:335-344, Task.ts:3318-3335).
Resolution
Forward cancellation to Poe and other affected providers. Ensure a stalled summary stream and its condense lease settle on cancellation.

Resolve a mutation gap
Add or strengthen a focused test that fails under the mutation. If the mutant is equivalent, request maintainer approval for the narrowest mutator-specific exclusion and explain why it cannot change behavior:
// Stryker disable next-line ConditionalExpression: normalized input cannot reach the alternate branch
const result = condition ? value : fallback
Broad all exclusions and exclusions without a concrete reason are reported as advisories.

Review comments at @src/core/task/__tests__/Task.idle-condense.spec.ts:
- Line 234: Add idle-scheduling coverage through Task.ask in the “Task idle
condensing — arming the timer” test suite, verifying pending-followup,
resumable, and idle asks schedule after the two-second transition, while tool
and command asks do not schedule idle work.
Review comments at @src/core/task/Task.ts:
- Line 2678: Update the idle-gate override resolution around
getCurrentProfileId(state) to use the delegated child’s task-local profile
rather than the global profile, so its threshold and delay are selected for that
task.
- Line 509: Restore lastActionWasCondense from the persisted task state when
reopening a task, before arming the resume timer, so a recently condensed
context suppresses another idle condense. Locate the reopening flow in Task and
reuse the existing persisted-state mechanism without changing other timer
behavior.
- Around line 2756-2757: Update the API-work completion flow guarded by
activeApiWork so that, after API work finishes, it re-arms the existing timer
only if the same follow-up remains pending and eligible for idle condensing;
preserve the current behavior when no eligible follow-up remains.
- Around line 2759-2764: Update the idle-condense flow around
evaluateIdleCondense in Task so user activity invalidates pending evaluations,
and verify an evaluation is still current before setting idleCondenseInFlight or
proceeding to condense. Coordinate condensing with newly started work so stale
evaluations cannot overwrite conversation updates or summaries that omit them.
- Line 2773: Update the task-history flow around condenseContextWithLease so
queued messages and direct responses wait until idle condensation settles before
modifying API history. Preserve serialization on both success and failure, and
ensure condensation failure releases any waiting responses without leaving the
task blocked.
- Around line 2731-2736: Update the idle-condense timer scheduling around
idleCondenseTimeoutRef so it never passes Node a delay above the supported
maximum; reject unsupported durations or schedule them in bounded intervals,
ensuring onIdleCondenseTimerFired runs only after the full requested idle
duration.
Review comments at @src/core/webview/webviewMessageHandler.ts:
- Around line 928-932: Update the profile override normalization in the visible
Object.fromEntries mapping so invalid delay or threshold values preserve global
inheritance rather than becoming valid overrides through clamping. Keep the
existing sentinel behavior, and ensure invalid profile values such as negative
delays or below-minimum thresholds do not override the configured global
settings.
- Line 937: Update the settings-save flow around provider.contextProxy.setValue
to re-evaluate a waiting task for idle condensing after relevant settings are
saved, including when idle condensing has just been enabled and the task is
already above the threshold. Keep active tasks ineligible and preserve the
existing eligibility checks.
- Around line 911-918: Update the idle-override mapping that uses
clampIdleCondensePercent to resolve each profile’s effective main threshold
using its profile ID before clamping that profile’s idle value. Use the profile
threshold when available, falling back to the existing global/default threshold,
and preserve the special -1 value unchanged.
Review comments at @webview-ui/src/components/chat/ChatTextArea.tsx:
- Around line 627-629: Update the idle-condense reset logic using
lastIdleCondenseResetRef and vscode.postMessage so every edit restarts the
countdown, including edits within the one-second throttle window; do not
suppress an edit’s reset notification.
Review comments at
@webview-ui/src/components/settings/ContextManagementSettings.tsx:
- Around line 794-806: Add an accessible name to the idle-time Input by using
the existing translated idle-time label as its aria-label. Keep the current
input behavior and other attributes unchanged.
- Around line 730-731: Add a visual test for the enabled idle context panel
rendered by the idleCondenseContext branch in ContextManagementSettings: create
a *.visual.tsx snapshot in the existing visual-test location, covering the
enabled panel and its narrow-width layout. Follow established gallery and
snapshot conventions so layout and theme changes are captured.
- Around line 216-220: Update the effective threshold calculation for
selectedIdleProfile so the displayed value is capped at the profile’s main
threshold, matching the runtime behavior while preserving the inherited idle
threshold setting. Keep the existing fallback for undefined or disabled profile
thresholds, and apply the cap only to the displayed value.
- Line 720: Replace the `any` annotation in the `idleCondenseContext` checkbox
handler with the appropriate event type for its checkbox element, so
`e.target.checked` is type-checked while preserving the existing
`setCachedStateField` update.

- Settings View Pattern: When working on `SettingsView`, inputs must bind to the local `cachedState`, NOT the live `useExtensionState()`. The `cachedState` acts as a buffer for user edits, isolating them from the `ContextProxy` source-of-truth until the user explicitly clicks "Save". Wiring inputs directly to the live state causes race conditions.

## Visual Tests (Playwright Story Gallery)
### When a UI change needs a snapshot
Skip a visual test when the change is behavior-only (state transitions, handler wiring, validation) — those belong in Vitest. Visual tests are for what JSDOM cannot verify.
The review's main premise is contradicted. The fixture's api_req_started includes cost: 0.05, so the stated reason for isStreaming to be true is absent. The test also asserts queueMessage after the condenseTaskContextStarted state update has flushed. If the isCondensing term were removed while isStreaming is false and the queue is empty, the same assertion would fail. The condensing branch is therefore covered by this test.

## ESLint Suppressions
`src/eslint-suppressions.json` tracks per-file counts of suppressed lint rules. Suppression counts must never increase. When touching a file, prefer reducing its count when the fix is local and low-risk; avoid broad unrelated cleanup.

2750-2757: Retry the idle gate when evaluateIdleCondense() fails after a settings save.
getTaskProfileId itself is correct. It resolves the task-local profile and falls back safely.
A past review comment raised a related concern: a failed gate after reevaluateIdleCondenseAfterSettingsSave() leaves no countdown armed and schedules no retry. That concern still applies. This change does not add a retry, so it is not a new defect here.
…alidation, gate retry)
CodeRabbit follow-ups on PR Zoo-Code-Org#2340:
- ChatView: post idleCondenseReset when a followup suggestion is
shift-clicked into the input and when handleSetChatBoxMessage replaces
the draft; both mutate inputValue without a textarea onChange, so the
idle countdown kept running against a prompt the user is editing.
- webviewMessageHandler: only finite numbers count when resolving the
main auto-condense percent that idle thresholds clamp against (a
hand-crafted non-numeric message value poisoned every clamp with NaN),
and reject a non-finite autoCondenseContextPercent before persisting it
so garbage never reaches storage.
- Task: retry the idle-condense gate after a settings-save re-evaluation
throws (e.g. transient provider getState failure) on a bounded backoff
(1s/5s/15s), respecting later cancellation, settings changes, abort,
and active API work. A failed re-eval leaves no countdown armed; the
retry uses a separate timer ref cleared by cancelIdleCondenseTimer.
maybeStartIdleCondenseTimer now returns "armed" | "declined" | "failed".
Tests:
- Task.idle-condense.spec: transient/persisting state-read failure,
cancel-during-retry, later-save-supersedes-retry; outcome-typed stubs.
- ClineProvider.spec: non-numeric autoCondenseContextPercent message is
ignored when clamping idle thresholds (and not persisted).
- ChatTextArea.spec: idleCondenseReset on enhanced-prompt replacement and
on command/mode/mention context-menu selections.
- ChatView.spec: shift-click suggestion posts idleCondenseReset.

setChatBoxMessage invoke path: dispatch the corresponding invoke message and
assert vscode.postMessage receives an idleCondenseReset message. Keep the test
focused on this behavior.

Failed pre-merge checks:
- Regression Evidence:
Add component tests that assert `idleCondenseReset` after
`insertTextIntoTextarea` and after programmatic mention deletion.
- Persistence Integrity:
Propagate history-save failures to the condense path. Retry or restore the
previous history, and report failure instead of recording a successful condense
until the replacement is durable.
- Lifecycle Resource Cleanup:
Forward cancellation to Poe and any other affected providers. Ensure the summary
stream and condense lease settle on cancellation, including when a provider
stalls.

Description
This PR adds an optional "Idle Condensing" feature to context management. When the user enables it, an active task starts an idle countdown after a model response ends with context above the idle trigger threshold. The countdown condenses the context when it expires, even when the context is only partially full.
A large fraction of the 40+ edited files are just adding new test UI cases for the config section and how user messages queue up while the condense is in progress. The actual code change is not too crazy.
How it works:
Task,maybeStartIdleCondenseTimer()arms the countdown after each model response, andevaluateIdleCondense()re-checks every gate (enabled, active task, threshold, no condense in flight) both at arm time and at expiry. Typing in the chat box resets the countdown. Sending a new prompt cancels it. Task disposal cancels it.condenseContextWithLease(). Before it runs, the backend postscondenseTaskContextStarted; in afinallyblock it postscondenseTaskContextResponse. The chat therefore shows the same "Condensing context..." row with its busy icon that a manual condense shows, while the chat box keeps the normal press-to-send state. Messages sent during a condense queue and drain through the existingprocessQueuedMessages()path.Pre-Submission Checklist

The in-chat condense cue reuses the existing "Condensing context..." row that a manual condense already renders, so the chat surface is unchanged.
