What & why

Self-hosted / OpenAI-compatible models (custom OpenAI endpoint, LM Studio, Ollama, and similar) do not advertise supportsReasoningEffort in the model registry, so the dynamic thinking effort (DTE) features — set_thinking_effort tool, composer ThinkingEffortToggle, TaskHeader chip, new_task thinking_effort param — were silently disabled for them even when the underlying model supports effort levels (e.g. Qwen3 via LM Studio).

F7 lets the user declare the effort levels their model supports, per API profile, via a new provider setting.

Design (conservative, additive)

  • New provider setting (packages/types/src/provider-settings/common.ts): supportedReasoningEfforts: z.array(reasoningEffortExtendedSchema).optional() on baseProviderSettingsShape — a per-profile declaration of canonical effort levels (canonical enum only; the UI-level "disable" sentinel cannot be declared).

  • Single resolution semantic, applied on both sides: when the resolved ModelInfo does NOT have supportsReasoningEffort (undefined) AND the profile declares a non-empty supportedReasoningEfforts, the model is treated as supporting exactly that array. Registry values are NEVER overridden (fill-in-the-gap only), so registry models (deepseek, openrouter, gemini, friendli catalogs, etc.) are untouched.

  • Extension side: small shared helper withDeclaredReasoningEffort(modelInfo, settings) in src/api/model-capabilities.ts, applied at the construction sites where OpenAI-compatible ModelInfo reaches consumers via getModel():

    • BaseOpenAiCompatibleProvider.getModel() (covers friendli/fireworks/baseten/sambanova/zai)
    • FriendliHandler.getModel() (custom override)
    • OpenAiHandler.getModel() (custom OpenAI endpoint, incl. DeepSeek/Kimi/Moonshot/Mimo subclasses)
    • LmStudioHandler.getModel()
    • NativeOllamaHandler.getModel()
    • RouterProvider.getModel() (covers LiteLLM, kenari, nanogpt, opencode-go, vercel-ai-gateway, zoo-gateway)

    All downstream DTE consumers (task.api.getModel().info in SetThinkingEffortTool, NewTaskTool, filter-tools-for-mode, webviewMessageHandler.setTaskThinkingEffort, request transform capability gates in shared/api.ts / api/transform/reasoning.ts) pick the capability up automatically — no request transforms changed; the existing capability gate already controls the reasoning_effort / OpenRouter reasoning envelope emit once capability is present.

  • Webview side: mirror helper resolveReasoningEffortCapability(model, apiConfiguration) in webview-ui/src/utils/thinkingEffort.ts, applied inside computeThinkingEffortDisplay so the composer toggle and TaskHeader chip render for declared models (both surfaces read the webview state ModelInfo, which has no extension-side info).

  • Experiments-screen hint (ExperimentalSettings.tsx): a small info line under the Dynamic thinking effort row noting that OpenAI-compatible profiles can declare supported effort levels per profile; the declared effort is sent per request but the local server may ignore the parameter.

  • i18n: new key settings:experimental.DYNAMIC_THINKING_EFFORT.hint added to all 18 locales (tab-indented JSON, CRLF preserved, node scripts/find-missing-translations.js passes).

Tests (all passing)

  • packages/types (provider-settings.test.ts): schema accepts canonical declarations across provider branches, rejects non-canonical values ("turbo") and the "disable" sentinel, accepts empty/omitted. Full types suite: 382 passed.
  • Extension unit (src/api/__tests__/model-capabilities.spec.ts): registry-wins (array + boolean), fill-in, empty/undefined declaration = no-op, no shared mutation.
  • Extension handler-level (src/api/providers/__tests__/f7-declared-reasoning-effort.spec.ts): fill-in visible at getModel() for OpenAiHandler (sane defaults + custom model info), LmStudio, NativeOllama (via public fetchModel()), BaseOpenAiCompatibleProvider subclasses, and RouterProvider fallback (LiteLLM); registry-wins and no-declaration no-ops.
  • Webview (webview-ui/src/utils/__tests__/thinkingEffort.spec.ts): undefined capability + supportedReasoningEfforts: ['low','high','max'] resolves with those levels; registry value wins over declaration; no declaration = null; disable-sentinel exclusion preserved.
  • Regression (touched paths): base-openai-compatible, openai, lm-studio, lite-llm, friendli, zai, fireworks, baseten, sambanova, native-ollama, webviewMessageHandler thinking-effort, setThinkingEffortTool, newTaskThinkingEffort, filter-thinking-effort, filter-tools-for-mode, shared api — all green.
  • Typecheck/lint: pnpm --filter @roo-code/vscode-webview exec tsc and root pnpm check-types (turbo) both exit 0; eslint clean on changed files; src/eslint-suppressions.json unchanged.

Branch note (addendum pattern)

Per the established DTE addendum-PR pattern (same as feat/dte-5-e2e / feat/dte-3-e2e), this branch is cut from the composed DTE head 9b6c8bc9f (feat/dte-trial-all), so the diff vs upstream main includes the whole 7-PR DTE series. The new F7 delta vs 9b6c8bc9f is 32 files: +621/−39 lines.

Documentation impact

No user-facing docs required: the feature is gated behind the DYNAMIC_THINKING_EFFORT experiment, and an in-app hint under the DTE row of the experimental settings documents the new provider setting (localized, 18 locales).

…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.
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.
Address PR review feedback on set_thinking_effort (DTE series 3/5):

- Executor: seed the per-task guard history with the task's effective
  baseline so returning from a changed value to the original baseline is
  refused as oscillation (A -> B -> A); existing no-op behavior preserved.
- Parser: only build nativeArgs when effort AND reason are strings; a
  non-string payload now fails at parse time and cannot reach the executor.
- Gating: a supportsReasoningEffort array that only lists 'disable' no
  longer exposes the tool (it could apply no level).
- i18n: translate the new thinkingEffort chat strings into all 17
  non-English webview locales (placeholders preserved).
- Tests: regression tests for each change plus branch-coverage for the
  previously partial lines (non-string args, 'disable'-only capability,
  baseline oscillation, partial streaming without params, description
  fallback, capability robustness). All touched patch lines are now
  fully branch-covered (codecov patch partials resolved).

CodeRabbit: Zoo-Code-Org#1354
… post-mode-switch revalidation, ask prefill normalization)
Adds a second DTE e2e suite that drives one task through a scripted switching sequence (baseline -> applied -> no-op -> applied -> oscillation refusal) against openai/gpt-5.1, asserting the per-request OpenRouter reasoning envelope plus the display says and tool results. Extracts the shared OpenRouter capture proxy from thinking-effort-tool.test.ts into thinking-effort-proxy.ts and switches that suite's request lookups to raw-body tool-call-id matching. Fixtures are scoped by model + hasToolResult + unique turnIndex because aimock's toolCallId matcher only inspects the last message and post-tool requests end with a fresh user message.
easonLiangWorldedtech pushed a commit to easonLiangWorldedtech/Zoo-Code that referenced this pull request Aug 24, 2026
The toolCallId matcher only inspects the last message of the request, but post-tool requests now end with a fresh user env-details message, so the old thinking-effort-tool fixture could never match (aimock 404 -> 30s e2e-mock timeout). This merge brings the turnIndex-scoped aimock fixtures, the shared OpenRouter capture proxy, and the new effort-switching suite; the 5 conflicting locales are resolved as translated name/description (e2e branch) plus the F7 supportedReasoningEfforts hint (HEAD).
CodeRabbit pre-merge check on the addendum (docstring coverage 14.29% < 80%,
7 functions across 3 files): add JSDoc to the five internal proxy helpers
and firstRequestCarrying so every function touched by this diff is
self-documenting (withOpenRouterCaptureProxy was already documented).
… event race)

CI e2e-mock failed 2 !== 3 on "exactly three thinkingEffort display says":
the final display say is observed on the Message channel after the
TaskCompleted event resolved waitUntilCompleted (separate event channels,
no cross-channel ordering guarantee; under CI load the queue lags by more
than one turn). Await the expected says with a bounded settle (5s, 100ms)
before detaching the listener: a genuine shortfall still fails the same
assertion, the race no longer does.

Anchor the DTE fixture match keys to unique per-scenario identifiers. Both new fixture files select responses using model, hasToolResult, and turnIndex. Those keys are not unique to these suites, so any other suite that drives the same model at the same turn index can match these entries and receive a set_thinking_effort or attempt_completion response. The path instructions require stable, unique prompt-text anchors and require multi-turn fixtures to chain on toolCallId.

  • apps/vscode-e2e/fixtures/thinking-effort-tool.json#L18-L23: replace the model/hasToolResult/turnIndex match with "toolCallId": "call_dte_e2e_001", which the preceding fixture already emits.
  • apps/vscode-e2e/fixtures/thinking-effort-switching.json#L3-L8: add a unique userMessage marker to the turn-0 entry, then chain the follow-up turns on the call_dte_sw_00* tool call IDs instead of model and turnIndex.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Clear the Anthropic and reasoning fields in suiteTeardown.

Two tests persist anthropicBaseUrl set to the ephemeral proxy origin (lines 233 and 435). The proxy server closes when withEffortProxy returns, so that port is dead afterwards. restoreOpenRouterConfig restores only the OpenRouter fields, so anthropicBaseUrl, apiKey, enableReasoningEffort, and reasoningEffort stay in the persisted configuration.

If a later suite in the same run selects apiProvider: "anthropic" without overriding the base URL, its requests go to the closed local port and fail with a connection error.

Clear the fields this suite set.

The path instructions require clearing prior provider fields when changing persisted provider or model settings.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Apply metadata.reasoningEffort when building provider requests.

ApiHandlerCreateMessageMetadata.reasoningEffort is the task-local override. These handlers now advertise declared capability, but they still derive outgoing effort from persisted this.options, or do not send an effort value. A composer or set_thinking_effort update can therefore change task state without changing the next provider request.

  • src/api/providers/base-openai-compatible-provider.ts#L252-L254: resolve the request-local effort before building the provider request.
  • src/api/providers/friendli.ts#L82-L84: pass metadata into buildFriendliReasoningParams() and give it precedence over settings.
  • src/api/providers/lm-studio.ts#L199-L206: apply the effective task-local effort in the LM Studio request path, or do not expose this capability for this handler.
  • src/api/providers/native-ollama.ts#L548-L552: pass metadata into getOllamaThinkParam() so it overrides this.options.reasoningEffort.

@coderabbitai review

Follow-up to the CodeRabbit docstring-coverage pre-merge check. Document the
functions introduced or touched by this PR's stacked diff that still lacked
JSDoc:

- SetThinkingEffortTool: effortRank, getGuardState, execute, handlePartial
- filter-tools-for-mode: applyModelToolCustomization (its doc block was
  orphaned by an intervening interface; moved it directly above the
  function)
- router-provider: supportsTemperature (line re-touched by the F7 diff)

Comments only; no behavior change.

Follow-up to the 2026-08-24 CodeRabbit full review of this stacked PR. Four
major findings, three fixed, one documented as design:

1. new_task schema strict-mode violation: thinking_effort was in properties
   but not required, which the Anthropic API rejects under strict: true +
   additionalProperties: false (the whole tool definition fails). It now
   uses the same ["string", "null"] + required pattern as todos; null is the
   omitted-value sentinel the tool treats as absent (unit-tested).
2. NewTaskTool: the invalid thinking_effort path now advances the
   consecutive-mistake guardrail and records the tool error like every other
   failure path, so a model repeating an unsupported effort trips the
   mistake loop (unit-tested).
3. E2E suite teardown: the new_task suite switches the profile to the
   Anthropic provider with an ephemeral proxy base URL and sets the global
   reasoning-effort fields; the teardown now explicitly clears them
   (anthropicBaseUrl, apiModelId, enableReasoningEffort, reasoningEffort)
   so a later suite selecting the anthropic provider is not pointed at the
   closed local port and does not inherit this suite's effort baseline.
4. Task-local effort on OpenAI-compatible providers: documented in the PR
   discussion rather than changed - setRuntimeThinkingEffort rewrites the
   per-task apiConfiguration and rebuilds the API handler, so provider
   requests are built from the task-local config (the switching e2e asserts
   the wire envelope changes on the request after an applied change); the
   metadata.reasoningEffort per-request override is the PR-2 Anthropic
   channel, and this PR's design deliberately keeps existing wire emit
   unchanged (plan section 12.1, user-confirmed caveat that some local
   servers ignore the parameter).

Type surfaces: NativeToolArgs.new_task.thinking_effort and ToolUse.params
now admit the null sentinel. tsc clean, eslint clean, 55 unit tests + 5 DTE
e2e suites passing locally.

Response to full-review findings (2026-08-24)

All four major findings from the full review are addressed — three fixed in 106a389e8, one confirmed as design:

1. new_task schema strict-mode violation — src/core/prompts/tools/native-tools/new_task.ts

Fixed. This was a real bug: under strict: true + additionalProperties: false, the Anthropic API rejects the entire tool definition when a property is not in required. thinking_effort now uses the same ["string", "null"] + required pattern as todos (null = the omitted-value sentinel, unit-tested); the type surfaces (NativeToolArgs.new_task, ToolUse.params) admit the null sentinel.

2. Mistake guardrail on the invalid-effort path — src/core/tools/NewTaskTool.ts

Fixed. The invalid thinking_effort path now runs the standard failure triplet (consecutiveMistakeCount++, recordToolError("new_task"), didToolFailInCurrentTurn = true) exactly like every other failure path in that execute(); covered by a unit test asserting all three effects.

3. E2E suite teardown — apps/vscode-e2e/src/suite/new-task-thinking-effort.test.ts

Fixed. restoreOpenRouterConfig now explicitly clears the four fields this suite sets (anthropicBaseUrl, apiModelId, enableReasoningEffort, reasoningEffort). saveConfig is a full profile replacement, so the persisted profile is clean either way; the explicit clears also reset the in-memory contextProxy settings, so a later suite selecting the anthropic provider is not pointed at the closed local port and does not inherit this suite's effort baseline. apiKey is deliberately left as-is (secret-state key; both anthropic suites set it explicitly).

4. metadata.reasoningEffort in the OpenAI-compatible handlers — base-openai-compatible-provider.ts / friendli.ts / lm-studio.ts

Confirmed as design; no code change. The task-local effort reaches these providers through the per-task configuration channel, and that channel is verified on the wire:

  • Task.setRuntimeThinkingEffort rewrites the per-task apiConfiguration.reasoningEffort (Task.ts L1595) and immediately rebuilds the API handler from it (L1606), so a provider's this.options is the task-local configuration, not the persisted global settings.
  • The e2e switching suite asserts exactly this on the wire: baseline reasoning.effort = "low" → "medium"/"high" after an applied change → unchanged after a refused change.
  • metadata.reasoningEffort is the PR-2 per-request override, consumed by the Anthropic handler (anthropic.ts L108). F7 deliberately keeps existing wire emit unchanged (plan §12.1 item 3, user-confirmed caveat that some local servers may ignore the parameter); the declared array drives validation/UI/clamping, and the experiments hint documents the caveat.

Verification: tsc clean (src + e2e), eslint clean, 55 unit tests + all 5 DTE e2e suites passing locally (18s, mock replay).
