feat(webview): thinking effort surfaces — header chip, composer toggle, in-chat display - #1359
Conversation
…nd adaptive effort envelope DTE series 2/5 (part of Zoo-Code-Org#1329). - ApiHandlerCreateMessageMetadata.reasoningEffort: per-request override channel - resolveEffectiveReasoningEffort: single shared resolution point (override > settings > model default) - AnthropicHandler: adaptive output_config.effort envelope in both requestParams branches (in-range only) - Task: setRuntimeThinkingEffort/getRuntimeThinkingEffort with in-memory apiConfiguration merge/restore, per-request metadata at all four createMessage sites, dispose() reset; never persisted
DTE series 2/5 — addresses the CodeRabbit review finding on Zoo-Code-Org#1338: when a task-local thinking-effort override is active, updateApiConfiguration() now re-captures the incoming profile's reasoningEffort as the restore value and re-applies the override on top of the new in-memory copy, so clearing the override restores the NEW profile value instead of the stale one. Additive: activation and clearing semantics are otherwise unchanged. Adds two regression tests (override active + profile switch restores new value; inactive updateApiConfiguration unchanged behavior).
DTE series 2/5 — addresses the CodeRabbit docstring-coverage warning on Zoo-Code-Org#1338 (33.33% < 80% across the functions touched by the diff): - AnthropicHandler.createMessage: documents the shared effective-effort resolution and the adaptive output_config.effort envelope (in-range only). - Task.dispose: documents centralized teardown incl. the transient task-local override reset. - Task.updateApiConfiguration: documents the override-preservation behavior (re-captured restore value + re-applied override on the new in-memory copy). Comment-only change: 30/30 patch lines and 10/10 branches unchanged; 317/317 tests and tsc --noEmit re-verified green.
…/dte-3-native-tool
Add the set_thinking_effort native tool (DTE series 3/5): the model adjusts its own per-turn thinking effort mid-task with no approval gate. - Guardrails: one-line chat notification (success or refusal), escalation cap (max 3 upward changes per task), A->B->A oscillation refusal, hard clamp to the model capability array (ties toward the lower level). - Gating: dynamicThinkingEffort experiment + model supportsReasoningEffort (non-empty array or true), evaluated at task start so the tool list stays stable within a task (prompt-cache safety). - Display: webview ChatRow one-line row (applied / oscillation / escalation refusal), i18n keys in all 17 locales; partial streaming updates the same line. - Tests: executor (clamp/cap/oscillation/no-op/no-approval/display), parser (partial + complete), dispatch, gating matrix, schema wiring, ChatRow display. Stacked on DTE PR-1 (experiment flag) and PR-2 (task-local runtime effort state). Closes Zoo-Code-Org#1330.

…real Task contract
Status: fresh CI green, all CodeRabbit findings resolvedCI (head ac84f5e): full run all green — unit x2, e2e-mock, webview-visual (against the 4 committed thinking-effort baselines), check-translations, knip, CodeQL, and both codecov/patch gates. CodeRabbit triage (3/3 used across this PR):
No /meow: no file was skipped as "similar to previous changes" (the 3 "skipped" entries in the review are CodeRabbit sandbox ESLint dependency errors, not review skips). Coverage: codecov/patch + webview-patch both pass; scoped v8 coverage 100% on every modified/new line (new files 100%; the one branch codecov exposed — ClineProvider taskThinkingEffort object path — is now behavior-tested at the real no-override shape). Notes: stacked on 0ab4a60 (standalone diff 0ab4a60...HEAD, ~960 diff lines); #1345 still OPEN at 391e5aa so the toggle stays self-contained with the pending-overlap note; e2e round-trip smoke stays in the separate addendum PR (dte-e2e-plan Part C) to protect the <=1000-line standalone-diff cap. Update 2026-08-24: manual surfaces are now normal features (head 784ee90)Design change (user directive): the composer toggle and TaskHeader chip were gated behind the dynamicThinkingEffort experiment flag; user expectation is that they are normal functions — visible whenever the selected model advertises per-request reasoning effort, with the experiment flag gating only the model-driven set_thinking_effort tool. Verified before coding: the entire extension-side pipeline (setTaskThinkingEffort handler, taskThinkingEffort state push, per-request effort envelope) was already ungated — only the webview display util early-exited on the flag. Commit 784ee90 (7 files, 57+/57−, explicit-path): computeThinkingEffortDisplay() drops the experiments parameter and returns null only when the model does not advertise per-request effort; ThinkingEffortToggle + TaskHeader stop reading experiments for this display; specs updated to the new contract (experiment-off + capable model now asserts the resolved display, incl. a task-local source-you case; capability-gate null cases kept); the Playwright CT fixture keeps its experiment-on initial state so baselines render the identical component state. CI (head 784ee90): full run 17/17 green — unit x2, e2e-mock, webview-visual, check-translations, knip, CodeQL, and both codecov/patch gates (re-verified after the push). CodeRabbit incremental review (range ac84f5e..784ee90): no actionable comments. One file skipped as similar to previous changes (ThinkingEffortToggle.visual.fixture.tsx, comment-only change; the fixture's rendered state is unchanged and the Docker visual run confirmed 0 baseline drift) — /meow not warranted, rationale documented here. Local evidence: check-types 11/11; eslint --max-warnings=0 on all 7 touched files; 57 vitest tests green across the 3 touched suites + ChatRow no-regression; 17-locale translation check clean; Playwright CT (official Docker image) 28/28, 0 baseline drift. PR body updated to reflect the new gating semantics (manual surfaces = capability-gated normal features; experiment gates only the model-driven tool). |
…ent flag The manual user-facing surfaces (composer bottom-bar toggle and task header chip) are now normal features: they render whenever the selected model advertises per-request reasoning effort support (supportsReasoningEffort boolean-true or a non-empty level array), regardless of the dynamicThinkingEffort experiment flag. - computeThinkingEffortDisplay() no longer takes the experiment flag and returns null only when the model does not advertise per-request effort support. - ThinkingEffortToggle and TaskHeader stop reading `experiments` from the extension state for this display. - The dynamicThinkingEffort experiment now gates only the model-driven set_thinking_effort tool exposure. The rest of the extension-side pipeline (setTaskThinkingEffort handler, taskThinkingEffort state push, per-request effort envelope) was already ungated. - Playwright CT fixture keeps its experiment-on initial state so the baselines render the identical component state (verified: 0 baseline drift).
