Closes#1378

Addendum to #1330 (DTE series 3/5 — set_thinking_effort native tool). Parent feature PR: #1354 (feat/dte-3-native-tool).

Summary

E2E addendum for the DTE (dynamic thinking effort) series: proves the set_thinking_effort mid-task workflow across the real extension-host boundary, using the same aimock fixture convention as the rest of the suite.

This is a standalone addendum, not part of the <=1000-line 5-PR DTE series.

What the test exercises

apps/vscode-e2e/src/suite/thinking-effort-tool.test.ts (+ fixture apps/vscode-e2e/fixtures/thinking-effort-tool.json):

  • OpenRouter provider, model openai/gpt-5 (live catalog advertises reasoning in supported_parameters, so the fetcher resolves the reasoning-effort capability), experiments.dynamicThinkingEffort enabled, enableReasoningEffort on.
  • aimock 2-turn fixture (per apps/vscode-e2e/AGENTS.md multi-turn convention): turn 1 (userMessage + sequenceIndex: 0) -> set_thinking_effort tool call; turn 2 (scoped match: model: "openai/gpt-5" + hasToolResult: true + turnIndex: 1) -> attempt_completion. The toolCallId matcher is unusable here: aimock's match.toolCallId only inspects the last message of the request, and Roo-Code appends an environment_details (role:user) message after the tool result, so the follow-up request never ends with a tool message.
  • A local 127.0.0.1 capture proxy (pattern from anthropic-opus-4-7.test.ts) fronts /v1/chat/completions, forwards to aimock, and captures request bodies.

Three real-boundary assertions:

  1. The task completes with "42" after the mid-task tool round trip.
  2. The SetThinkingEffortTool display say("tool") carries the applied effort: {tool: "thinkingEffort", effort: "high", reason: "multi-step math"} (no refusal).
  3. The post-tool API request carries the applied effort in the OpenRouter reasoning envelope (reasoning.effort === "high"), while the pre-tool baseline request does not — i.e. Task.setRuntimeThinkingEffort -> merged in-memory configuration -> getOpenRouterReasoning is observable on the wire.

Deterministic and key-free: runs against aimock only (skips when AIMOCK_URL is absent). No runTest.ts changes.

Notes

  • Local runTest VS Code-host launch is limited on the author's machine (known host limitation); the CI e2e-mock job is the authoritative check.

Pre-submission checklist

  • pnpm --filter @roo-code/vscode-e2e check-types green
  • eslint src/suite/thinking-effort-tool.test.ts --max-warnings=0 green; no suppression count increases
  • Standalone diff within the 1000-line cap (test + fixture only, no runTest.ts changes)
  • Working tree clean: no suppression files, no husky/turbo-lint artifacts
  • CI e2e-mock green (run 32716616736, 5m38s; DTE test ✔ ~5s, main suite 84 passing). The first run's fixture-match 404 was root-caused (aimock toolCallId matcher only inspects the request's last message; Roo-Code appends environment_details (role:user) after the tool result) and fixed with a scoped match (model: "openai/gpt-5" + hasToolResult: true + turnIndex: 1 — see fixture rationale in the test header)
  • Stacked re-sync with feat(tools): set_thinking_effort native tool — model-driven per-turn thinking effort, no approval (DTE series 3/5) #1354 after bot-feedback fixes land (additive merges cfa6a647e + f309d3a6e + 1270e7a59; all checks re-verified green, 17/17)

Summary by CodeRabbit

  • New Features
    • Added experimental dynamic thinking-effort controls for supported models during tasks.
    • Added adaptive reasoning-effort support for compatible Anthropic requests.
    • Displays applied effort, request reasons, and refusal messages in chat.
  • Settings
    • Added a toggle for dynamic thinking effort, disabled by default.
  • Bug Fixes
    • Added safeguards and validation for unsupported levels, repeated oscillation, and excessive escalations.
  • Localization
    • Added translated settings and chat messages across supported languages.

…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). ClosesZoo-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).

Log every request the capture proxy sees and dump aimocks request journal after the wait so CI reveals the exact bodies the aimock matcher saw.
Filter model capability entries to SETTABLE_EFFORTS plus disable before nearest-level selection so a capability array containing only unrecognized values (e.g. [weird]) is refused via the standard tool-error path instead of being applied as the runtime effort. Add unit coverage for all-garbage and mixed garbage capability arrays.
Replace the any-typed renderChatRow/sayToolMessage helpers with the ClineMessage type and a ThinkingEffortSayTool payload shape (thinkingEffort tool discriminator over ClineSayTool fields), preserving the existing fixture values.
Translate the DYNAMIC_THINKING_EFFORT name/description out of English in zh-CN, ja, ko, ru, de, ca, pt-BR, tr, vi, nl and pl, matching the terminology already used in each locale chat.json thinkingEffort strings. find-missing-translations --area=webview is clean.
The aimock toolCallId matcher only inspects the LAST message of the request. The post-tool request ends with a role:user message (fresh environment details appended after the tool result), so the second fixture could never match and every request returned 404 No fixture matched. Match the follow-up on the DTE-only model (openai/gpt-5) plus hasToolResult, with turnIndex 1 tie-breaking the two requests, and remove the temporary DTE-DEBUG capture.

@easonLiangWorldedtech The E2E failure has a direct cause.

apps/vscode-e2e/fixtures/thinking-effort-tool.json is not valid JSON. Line 19 contains // comments. The aimock fixture loader uses JSON.parse, so it rejects the complete file before the tests start.

As a result, aimock does not register either DTE fixture. The DTE test then receives repeated 404 No fixture matched responses and times out after 30 seconds.

Remove Lines 19-22 from the JSON file. Move that explanation to the test file or to a TypeScript fixture if it must remain in source control.

"fixtures": [
{
"match": {
"sequenceIndex": 0,
"userMessage": "DTE_E2E_EFFORT_APPLY: answer the math question"
},
"response": {
"toolCalls": [
{
"name": "set_thinking_effort",
"arguments": "{\"effort\": \"high\", \"reason\": \"multi-step math\"}",

}
]
}

}

}

I also triggered the requested review.

Comment threadapps/vscode-e2e/fixtures/thinking-effort-tool.json Outdated
The previous commit placed a comment block inside thinking-effort-tool.json. JSON does not allow comments, so the aimock fixture-loader JSON.parse failed (Invalid JSON ... line 19 column 4) and SKIPPED the whole file: neither DTE fixture registered, both requests 404 No fixture matched, and the test timed out at 30s (CI run 32705689295). Remove the comment from the JSON, keep the model + hasToolResult + turnIndex match unchanged, and document the matcher rationale plus the plain-JSON constraint in the test file header.

DTE series 3/5 — E2E addendum: ready for review

All checks green on head 1270e7a59 (17/17), including e2e-mock (run 32716616736: the set_thinking_effort mid-task workflow passes across the real extension-host boundary — task completes, the display say carries the applied effort, and the post-tool OpenRouter request carries reasoning.effort: high on the wire).

Bot findings: all 6 (4 pre-merge + 2 from the intermediate JSON-fix commit) addressed with evidence and replied inline; CodeRabbit confirmations received on each.

Stacked state: synced with #1354 (additive merges cfa6a647e + f309d3a6e + 1270e7a59); this branch adds the e2e test + fixture only (standalone diff, no runTest.ts changes).

Please merge #1354 first (parent feature), then this addendum.

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.

197-236: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Move the exact tool-result strings to the unit layer.

The envelope assertions on reasoning.effort are the high-value cross-boundary checks. The bodyText.includes(...) assertions on the literal result strings, for example "Thinking effort is already 'medium'." and "oscillation between 'medium' and 'high' detected", duplicate what src/core/tools/__tests__/setThinkingEffortTool.spec.ts can assert directly. Any wording change then breaks this e2e suite for no boundary reason. Keep the envelope assertions here and assert the exact result text in the tool unit spec.

As per path instructions: "Keep e2e tests focused on high-value cross-boundary smoke coverage; do not place detailed protocol, parsing, storage, retry, or edge-case assertions there when lower-level tests can cover them."

… 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.

aimock JSON matchers cannot bind a post-tool turn to a toolCallId in this
pipeline: the OpenRouter provider converts the post-tool continuation to a
separate role:user environment-details message (mergeToolResultText is not
set for openai/* models), and aimock toolCallId matching only inspects the
LAST message, so it can never fire. Scope the fixtures with the flow keys a
JSON fixture can express instead: the first turn of each flow binds to its
unique prompt marker (DTE_E2E_SWITCH / the existing DTE_E2E_EFFORT_APPLY
marker), and every post-tool turn additionally matches the fresh
environment-details user message (userMessage "<environment_details>"), on
top of the existing model + hasToolResult + turnIndex keys. Verified
offline against aimock 1.35.0 loadFixtureFile/validateFixtures/matchFixture:
all seven scripted requests serve the intended fixture, and the two suites
still cannot cross-match. (CodeRabbit on trial PR 1379)
Replaces the two JSON fixtures with a JS module (src/fixtures/thinking-effort.ts,
same pattern as deepseek-v4.ts) after CodeRabbit confirmed the JSON scoping was
insufficient: post-tool requests end with a role:user environment-details message,
so aimock's toolCallId matcher (last message must be role:tool) cannot bind the
continuation turns and a JSON fixture cannot carry a predicate. Each turn is now
scoped to its own flow: the baseline turn binds to the suite's unique prompt
marker, and every continuation binds to the previous turn's unique tool call id
(call_dte_sw_001..004, call_dte_e2e_001), so no other suite can serve these
responses and the DTE suites cannot match unrelated turns. Verified locally with
the real extension host + aimock (USE_MOCK): both DTE suites pass (2 passing,
exit 0).
