feat(task-title): auto-generate task titles for new root tasks - #2398
This PR implements automatic task title generation for new root tasks. When a task starts, the system generates a short, user-friendly title (5–10 words in the user's language) in the background without blocking task execution or showing errors in chat.
Key Implementation Details
Data Model: Add optional autoTitle field to HistoryItem. Display priority: manual title > auto title > original prompt. This separation ensures manual titles always win structurally.
Storage Layer: Implement setAutoTitleIfAbsent method in TaskHistoryStore that validates disk state under lock before recording. This prevents deleted tasks from reappearing in multi-host scenarios.
Title Generation Service: Create TaskTitleService with concurrent queue (max 2 parallel requests, per-task deduplication). Trigger on first API call (totalTokensIn > 0), not at task creation, to avoid race conditions with the first agent request.
Generation Logic: Extract first 1,000 characters of prompt (skip images, truncate code blocks), send to TASK_TITLE support prompt, clean output (remove think tags, prefixes, extra punctuation), and emit 42-character fallback if LLM fails or times out.
Cancellation Policy:
User cancels: record free fallback title
Task deleted: skip recording
Task switched: continue (do not abort)
Exclusions: Skip subtasks, resumed tasks, short prompts (≤42 chars), and rate-limited profiles.
Settings: Add taskTitleGenerationEnabled (default: true) and taskTitleApiConfigId (optional, falls back to task profile).
Design Trade-Offs
Separate field: Avoids complex logic for manual-title precedence, rename cancellation, and retry state.
No Task.ts changes: Provider owns the service and subscribes to task events, keeping lifecycle/run-state/rate-limit code isolated.
No rate-limit clock integration: Prevents agent retry logic loops; instead, skip LLM for rate-limited profiles and record fallback only.
Trigger on first API call: Ensures history item exists and avoids competing with the first agent request.
15-second timeout: settleOnAbort wraps the promise so fallback is recorded even if provider ignores abort signal.
Multi-Host Safety
setAutoTitleIfAbsent validates disk state under lock: if record is missing, invalid, or already has autoTitle, it returns false without updating. This prevents a deleted task from reappearing when a late response arrives from another host.
Webview Changes
Update useTaskSearch selector to include both display title and original prompt, so users can still search by prompt text.
Fix TaskTitleEditor to treat auto title as a starting value; if user saves the same text, title clears (no change = no manual title).
Update ExtensionStateContext to handle late taskHistoryItemUpdated arrival before currentTaskItem.
Provider abort behavior: 14 providers support signal + timeout (HTTP request truly stops); 4 support signal only (client-side 15-second timeout via settleOnAbort); 9 ignore both (HTTP request continues up to apiRequestTimeout, late results are discarded). Follow-up PRs address per-provider optimizations (following feat(api): abort signal support for requesty (completePrompt + shared helpers) #1537 pattern).
Settings & Localization
UI: Prompts settings tab for TASK_TITLE, with toggle and API profile picker (parallel to ENHANCE tab).
18 locales: en, ko, ja, zh-CN, zh-TW, es, fr, de, it, pt-BR, ru, tr, vi, hi, id, pl, ca, nl.
Documentation string warns: lightweight non-reasoning profile recommended, cost not in task total, Copilot/VS Code LM consume quota, alternative profile sends prompt start to that provider.
Baseline images committed for regression coverage.
Documentation Updates
No documentation updates are required.
Additional Notes
Cost and Provider Behavior
Call cost: ~1,100–1,300 input tokens (150 for instruction + up to 1,000 for prompt; English ~250, Korean ~700) + 20–40 output tokens. Single call per task, no retries. Cost not included in task total; follow-up issue to aggregate auxiliary calls.
Provider abort signal handling varies; 15-second client-side timeout ensures promise settles even if provider ignores signal. Late responses are discarded by lock validation.
Reasoning model thinking tokens: Instruct users to select a lightweight profile in settings to avoid excessive token consumption.

New tasks can receive automatically generated titles, with options to enable or disable the feature and choose which API configuration to use.
Generated titles appear in task headers and history. Custom titles take precedence, and you can edit generated titles or search history by title or task prompt.
Improvements
Task titles are preserved during concurrent updates, and deleted tasks aren’t restored by title generation.
Localization
Added translations for task-title settings across supported languages.
The change adds background title generation for eligible new root tasks, stores generated titles separately from manual titles, and displays them in task headers and history. It adds settings for enabling generation and selecting an API profile, plus tests and translations.
Adds an enabled-by-default task-title setting and an optional API profile ID. The prompt settings UI exposes these options, and localized prompt text describes them. E2E configurations disable title generation.
Generation and scheduling src/core/task-title/TaskTitleService.ts, src/core/task-title/generateTaskTitle.ts, src/core/task-title/__tests__/*
Adds title input preparation, output cleaning, fallback titles, and asynchronous scheduling for eligible root tasks. The service limits concurrent jobs to two and handles cancellation, disposal, profile rate limits, and timeout behavior.
Guarded title persistence src/core/task-persistence/TaskHistoryStore.ts, src/core/task-persistence/__tests__/TaskHistoryStore.realConcurrency.spec.ts, scripts/check-task-store-concurrency.ts
Adds a locked write that sets an auto-title only when the task exists and has no auto-title. Tests and the concurrency model cover stale writes, deletion, competing auto-title attempts, and manual-title coexistence.
Connects title generation to task creation and token usage, cancels it on user cancellation or deletion, and disposes the service with the provider. State projections expose the settings, and task-history snapshots preserve manual and generated title fields.
Task title display and search webview-ui/src/components/chat/TaskHeader.tsx, webview-ui/src/components/history/*, webview-ui/src/context/ExtensionStateContext.tsx, webview-ui/src/context/__tests__/ExtensionStateContext.spec.tsx
Task headers and history use the manual title first, then the generated title, then the original prompt. Search includes both the display title and task text. History updates can populate the current task item when its ID matches the pinned task ID.

Merge Risk: Moderate · up to 5fbe8
Automatic titles can send the start of a task prompt to a provider that organization policy excludes, so check the title profile against the allow-list before merging. Titles for coding tasks can also lose underscores and asterisks, and evicted tasks may be held in memory until the provider is disposed. Both are minor.

Explanation
The history field, store concurrency protection, title display and editing, search, settings, localization, and their tests all support automatic task titles requested by issue #2333. Disabling generation in E2E and visual test setups isolates those tests from title-generation requests and supports reliable testing of the feature.
Full details: Linked Issues check
Explanation
Issue #2333 requires a title for a new root task after its first message and specifies the first 42 message characters as the failure fallback. TaskTitleService excludes prompts of 42 characters or fewer, so those tasks receive no generated title. fallbackTitle instead selects the first non-empty line, transforms URLs and mentions, and truncates at a word boundary. The added tests cover these behaviors but do not meet the issue requirements.
Resolution
Remove the short-prompt exclusion so eligible new root tasks with prompts of 42 characters or fewer receive a title. Use the first 42 message characters as the failure and timeout fallback. Add tests for both requirements.
Full details: Security Boundaries
Explanation
Title generation bypasses the organization provider allowlist. ClineProvider.ts:467-473 resolves any saved title profile without checking ProfileValidator, and TaskTitleService.ts:176-188 sends the prompt through that profile. If a saved profile is later prohibited by the organization, a user can still select it in PromptsSettings.tsx:298-304; a new task then sends its prompt to the prohibited provider. Normal task creation checks the allowlist at ClineProvider.ts:4395-4396.
Resolution
Validate the effective title profile against the current organization allowlist before every title request. Skip generation or use an allowed fallback when the profile is prohibited. Add tests for prohibited saved profiles and policy changes.
Full details: Persistence Integrity
Explanation
TaskHistoryStore.setAutoTitleIfAbsent evicts a task when readTaskFile returns null (lines 1035–1038). That helper also returns null for read errors such as EIO, not just a missing file. If a peer has updated the task and the next local task save runs before reconciliation, upsertCore treats the stale snapshot as a new item and writes every supplied field. This can overwrite the peer's persisted fields, such as mode.
Resolution
Distinguish a confirmed missing record from read and parse failures. Preserve the cache and report or retry failures. Add a test for a read error followed by a stale save after a peer update.
Full details: Regression Evidence
Explanation
Two changed behaviors lack focused regression coverage. - ClineProvider.ts:513-555 connects task creation, token usage, and user cancellation to title generation. Service tests call these methods directly, so they do not verify the provider event wiring. E2E tests disable title generation. - SettingsView.tsx:477-478,1002-1009 buffers and saves the title settings. PromptsSettings.taskTitle.spec.tsx:58-71,99-117 tests mock setters, while ClineProvider.spec.ts:4083-4095 sets stored values directly. Neither verifies the settings Save path.
Resolution
Add provider tests for title generation after token usage and for user versus non-user cancellation. Add a SettingsView test that changes both settings, saves them, and checks the update payload, including clearing the selected profile.
Full details: Lifecycle Resource Cleanup
Explanation
TaskTitleService retains abandoned task instances. onTaskCreated stores the full Task in candidates (lines 62–66), but removes it only after positive input-token usage, cancellation, deletion, or provider disposal. If a user starts another task before the first task reports usage, removeClineFromStack aborts and disposes the first task without setting user_cancelled. The new abort handler does not remove its candidate. Repeated switches retain disposed tasks until provider disposal.
Resolution
Remove unscheduled candidates when their task is evicted or disposed. Preserve the existing behavior that lets already scheduled title requests continue across task switches. Add a regression test for switching before positive token usage.

Completion-readiness changes belong in `scripts/check-completion-persistence.ts`; shared-store interleavings belong in `scripts/check-task-store-concurrency.ts`. Optional fan-out work belongs in `scripts/check-task-fanout-protocol.ts` and its separately scoped ticket until production transitions exist. Do not weaken bounds or remove an invariant merely to make CI pass. If state growth becomes difficult to control, split independent protocols or move the model to TLC/Quint with an implementation trace adapter rather than silently sampling the state space.

Titles for coding tasks often contain such tokens. The wrong title is stored and shown in history and the task header.
Unwrap only paired emphasis at word boundaries. Add test cases for snake_case, __init__.py, *.ts and **Title:** x. The **Title:** x case needs a check after the prefix strip.

Update the title-cleaning logic in cleanTitle so it removes only paired Markdown
emphasis markers at word boundaries, preserving underscores and asterisks inside
identifiers and globs. Add coverage for snake_case, __init__.py, and *.ts, and
verify **Title:** x is handled correctly after the title-prefix stripping step.

candidates retains full Task objects for tasks that never reach first API usage.
ClineProvider passes the live Task instance to onTaskCreated (line 515). schedule() and cancel() are the only places that delete a candidate entry.
removeClineFromStack() detaches the task listeners, so onTokenUsageUpdated never fires for an evicted task. A user can start a task and replace it before the first response completes. This also happens when the first request fails. The entry then stays in candidates. It holds the Task with its messages and API handler until dispose().
Add a discard(taskId) method. Call it when a task leaves the registry without a user cancel. The matching test "keeps running when the task is merely switched away" covers only running jobs, so it does not conflict.
🔧 Proposed fix
+ /** Drop a task that left the stack before its first API usage. */+ discard(taskId: string): void {+ this.candidates.delete(taskId)+ }
Then call this.taskTitleService.discard(task.taskId) in ClineProvider.removeClineFromStack() after the listeners are removed.

Review the replacement and indentation, then test before committing.

Check the title profile against the organization allow-list.
resolveProfile can return a profile that the allow-list excludes. TaskTitleService can then send the task prompt to that provider, even though task creation validates the task profile.
Reject disallowed title profiles before the request. If generation falls back to the task profile, check that profile against the current allow-list too.

Update resolveProfile and the TaskTitleService profile-resolution flow to reject
title profiles excluded by the current organization allow-list before sending
the task prompt; when generation falls back to the task profile, validate that
profile against the same current allow-list before using it. Preserve the
existing undefined result for rejected profiles.

Tie the API configuration label to its select control.
The <label> has no htmlFor and the SelectTrigger has no accessible name. Screen readers cannot tell which control the label describes. React Doctor reports this (label-has-associated-control). The existing ENHANCE block uses the same pattern, so this is an inherited gap. Fix it for the new block.
[warning] 283-283: Screen reader users can't tell which input this label names because it's tied to none, so add htmlFor or wrap the input inside it.
Tie every label to a control with htmlFor, or by nesting the input.

Description
This PR implements automatic task title generation for new root tasks. When a task starts, the system generates a short, user-friendly title (5–10 words in the user's language) in the background without blocking task execution or showing errors in chat.
Key Implementation Details

This separation ensures manual titles always win structurally.setAutoTitleIfAbsentmethod inTaskHistoryStorethat validates disk state under lock before recording. This prevents deleted tasks from reappearing in multi-host scenarios.TaskTitleServicewith concurrent queue (max 2 parallel requests, per-task deduplication). Trigger on first API call (totalTokensIn > 0), not at task creation, to avoid race conditions with the first agent request.TASK_TITLEsupport prompt, clean output (remove think tags, prefixes, extra punctuation), and emit 42-character fallback if LLM fails or times out.taskTitleGenerationEnabled(default: true) andtaskTitleApiConfigId(optional, falls back to task profile).Design Trade-Offs
