Standalone e2e addendum (DTE series 5/5)

This PR is a standalone e2e addendum — NOT part of the 5-PR dynamic thinking effort feature series. It adds vscode-e2e coverage for orchestrator new_task thinking_effort pass-through and lands independently on top of the feature branch once #1355 merges.

Stacked base

Sync with the feature branch (post-review-fixes)

  • Sync commit 1: f6e1178 — additive merge of feat/dte-5-orchestrator (head 4eb13a9, the CodeRabbit review-fix commit) into this branch. Brought in the boolean-capability normalization fix (Major feat: support OAuth 2.1 for streamable-http MCP servers #1 on feat(task): orchestrator new_task thinking_effort #1355): supportsReasoningEffort: true now normalizes to the full level set. Re-verified the e2e assertions against the fixed semantics — no spec-level changes were needed then.
  • Sync commit 2: d301642 — additive merge of feat/dte-5-orchestrator head 4a6ee69 into this branch. That commit fixes a functional bug this e2e suite caught on CI (run 32664059353, head f6e1178): NativeToolCallParser's new_task cases dropped thinking_effort from nativeArgs, so the model-specified effort never reached validation — the NEGATIVE scenario delegated a child task and hung until timeout instead of rejecting.
  • Sync commit 3: 630c49d — additive merge of feat/dte-5-orchestrator head 018f165 (the CodeRabbit follow-up fix that makes the post-mode-switch fallback say non-fatal so a rejecting notification cannot abort delegation). No e2e files changed; no e2e semantics affected — the NEGATIVE/INHERIT/EXPLICIT flows are unchanged.
  • Sync commit 4: 471490b — additive merge of feat/dte-5-orchestrator head 3ea9f63 (the CodeRabbit follow-ups: documented partial-provider-double comment + delegation-metadata assertion in provider-delegation.spec.ts, and localized new_task effort selector labels in ChatView.tsx reusing the existing settings:providers.reasoningEffort.* translation keys). No e2e files changed; the green e2e-mock run at 630c49d remains the authoritative verification for the e2e behavior.
  • Also on this head: 4f88bce fixes the effort proxy's upstream allowlist (a CodeRabbit finding on this PR) so the two intended targets — the local http://127.0.0.1 mock proxy and the live https://api.anthropic.com fallback — are both explicitly allowed; anything else still throws.
  • Because the tool error is only visible to the model as a tool_result in the parent's follow-up request (the extension emits no user-visible message for tool results), the NEGATIVE scenario's error-visibility assertion now runs against the wire boundary — the same local capture proxy used by the INHERIT scenario — asserting that a parent request carries both the DTE_E2E_NT_NEGATIVE_PARENT marker and the Invalid thinking_effort tool error. The no-child assertion (single observed task id) and the completion assertion are unchanged.
  • INHERIT/EXPLICIT semantics re-verified after both syncs:
    • INHERIT: no explicit thinking_effort → validation untouched; child request still carries the parent's effective effort (medium, settings-derived).
    • EXPLICIT: deepseek-v4-pro carries the array ["disable","low","high","max"]"high" still validates identically.
    • NEGATIVE: claude-opus-4-7's catalog entry has supportsReasoningBinary only and no supportsReasoningEffort (undefined) → stays unsupported; the call is now rejected before the approval ask, as the fixture sequence expects.
  • Scoped check-types + eslint re-run green on the e2e files after each merge; the fresh CI e2e-mock run at the final head is the authoritative verification.

What it adds

  • apps/vscode-e2e/src/suite/new-task-thinking-effort.test.ts — three deterministic mock-mode scenarios using unique DTE_E2E_NT_* markers:
    1. Inheritance: a new_task call without thinking_effort starts the child with the parent's current effective effort; a local wire-capture proxy asserts the child's real /v1/messages request carries the expected output_config.effort.
    2. Explicit: thinking_effort: "high" on a capability-array model (deepseek-v4-pro) round-trips schema → validation → approval → delegation; the child subtask completes on the real host. (No wire assertion: the DeepSeek handler resolves the request effort from settings only and does not consume the per-request override — and the only handler that does consume it, Anthropic, serves catalog models without a capability array, so no model today both passes the DTE 5/5 validation and propagates an explicit effort to the wire.)
    3. Negative guard: thinking_effort: "high" on a model without a capability array (claude-opus-4-7) is rejected before the approval ask — no child task is created (single observed task id) and the tool error is visible to the model on the wire.
  • apps/vscode-e2e/src/fixtures/subtasks.ts — the DTE_E2E_NT_* fixture markers/prompts plus addDteNewTaskEffortFixtures() (append-only; existing fixtures untouched).
  • apps/vscode-e2e/src/runTest.tsstrictly additive, required for the suite: registers the new fixtures with the mock in deterministic mode (1 added import name + 1 addDteNewTaskEffortFixtures(mock) call, mirroring the existing fixture registrations).

Environment note

Local runTest (real VS Code test host) cannot start on the author's host (known environment limitation — earlier local run failed with ERR_PNPM_RECURSIVE_RUN_FIRST_FAIL at VS Code launch). CI e2e-mock is authoritative for this suite.

Pre-submission checklist

  • pnpm --filter @roo-code/vscode-e2e check-types — exit 0 (initial + both post-sync runs)
  • eslint (touched e2e files: fixtures/subtasks.ts, runTest.ts, suite/new-task-thinking-effort.test.ts) — exit 0, no new suppressions (initial + both post-sync runs)
  • deterministic mock fixtures only (no timestamps / environment-specific data); unique markers
  • e2e assertions re-verified against the post-fix semantics (syncs f6e1178 and d301642); NEGATIVE visibility assertion moved to the wire boundary after the parser fix
  • CI e2e-mock run is the authoritative local-run substitute

Summary by CodeRabbit

  • New Features

    • Added selectable thinking-effort levels when approving delegated tasks.
    • New tasks can inherit the parent task’s effective thinking effort.
    • Supported effort options are displayed automatically, with sensible defaults when unavailable.
    • Added per-request reasoning-effort controls for compatible adaptive-thinking models.
  • Bug Fixes

    • Unsupported effort selections are validated before delegation and reported without preventing the task from starting.
    • Thinking-effort settings now remain consistent across delegated tasks, profile changes, and provider requests.

…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.

📝 Walkthrough

Walkthrough

The change adds optional thinking-effort support to new_task. It resolves inherited and explicit effort, validates model capabilities, exposes effort selection in the webview, applies Anthropic adaptive-thinking request envelopes, and adds unit and end-to-end coverage.

Changes

New-task thinking effort

Layer / File(s) Summary
Effort resolution and Anthropic requests
packages/types/src/vscode-extension-host.ts, src/api/..., src/api/providers/...
Request metadata and model settings resolve supported effort values. Anthropic adaptive requests include valid output_config.effort values.
Task state and child delegation
src/core/task/Task.ts, src/core/task/__tests__/*, src/core/webview/ClineProvider.ts, src/__tests__/*
Tasks retain runtime effort overrides, pass effective effort to children, restore configuration correctly, and clear transient state on disposal. Unsupported child-model values produce non-fatal errors.
new_task effort contract and execution
src/core/prompts/tools/native-tools/new_task.ts, src/core/assistant-message/..., src/shared/tools.ts, src/core/tools/...
The new_task schema, parser, types, validation, approval payload, and delegation execution support optional thinking_effort.
Approval messaging and effort selector
src/core/webview/..., webview-ui/src/components/chat/..., packages/types/src/vscode-extension-host.ts
Webview messages carry effort metadata. The chat UI displays supported levels and submits the selected value.
End-to-end delegation validation
apps/vscode-e2e/src/fixtures/subtasks.ts, apps/vscode-e2e/src/runTest.ts, apps/vscode-e2e/src/suite/...
End-to-end coverage verifies inherited effort, explicit "high" effort, and rejection on models without reasoning-effort capabilities.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🔵 Low · up to 47149

The PR adds deterministic end-to-end coverage for new-task thinking effort, but the stacked implementation still has two bounded correctness risks: an unapproved effort may affect a later delegation, and future supported effort levels may be rejected by a hard-coded list. The PR is mergeable with explicit owner awareness or follow-up.

Derive the level list from the shared schema.

reasoningEffortExtendedSchema.options already contains the seven valid levels and excludes "disable". Use it for NEW_TASK_EFFORT_LEVELS instead of duplicating the values, so schema changes cannot make isNewTaskEffortLevel reject valid levels.

CI green — e2e addendum for orchestrator new_task thinking_effort

All checks are green on head 471490b (all 17 distinct checks, including e2e-mock, both platform unit-test jobs, codecov/patch, codecov/patch/webview-patch, CodeQL, and webview-visual).

What it adds

Three deterministic mock-mode e2e scenarios in apps/vscode-e2e/src/suite/new-task-thinking-effort.test.ts (unique DTE_E2E_NT_* markers; append-only fixtures in fixtures/subtasks.ts; strictly-additive registration in runTest.ts):

  1. Inheritance — a new_task call without thinking_effort starts the child with the parent's current effective effort; a local wire-capture proxy asserts the child's real /v1/messages request carries effort: medium (settings-derived).
  2. Explicitthinking_effort: "high" on a capability-array model (deepseek-v4-pro, supportsReasoningEffort: ["disable","low","high","max"]) round-trips schema -> validation -> approval -> delegation; the child subtask completes on the real host.
  3. Negative guardthinking_effort: "high" on a model without a capability array (claude-opus-4-7) is rejected before the approval ask: no child task is created (single observed task id), the parent completes, and the Invalid thinking_effort tool error is asserted at the wire boundary — the extension emits no user-visible message for tool results, so the error reaches the model only as a tool_result in the parent's follow-up request; the same capture proxy asserts a parent request carries both the DTE_E2E_NT_NEGATIVE_PARENT marker and the tool error text.

Sync history with #1355 (feat/dte-5-orchestrator)

  • f6e1178 — merged the CodeRabbit review-fix commit (4eb13a9: boolean-capability normalization, post-mode-switch revalidation, ask-prefill normalization).
  • d301642 — merged 4a6ee69, which fixes a functional bug this suite caught on its first CI run (32664059353 @ f6e1178): NativeToolCallParser's new_task cases dropped thinking_effort from nativeArgs, so the model-specified effort never reached validation and the NEGATIVE scenario delegated a child and hung until timeout. Both parser cases now forward the argument, with regression unit tests.
  • 630c49d — merged 018f165 (the CodeRabbit follow-up that makes the post-mode-switch fallback say non-fatal). No e2e files changed.
  • 471490b — merged 3ea9f63 (the CodeRabbit follow-ups: the documented partial-provider-double comment + delegation-metadata assertion in provider-delegation.spec.ts, and the localized new_task effort selector labels in ChatView.tsx reusing the existing settings:providers.reasoningEffort.* translation keys). No e2e files changed.
  • The later feature-branch commit 026bca7 is test-only (unit-test hardening under src/__tests__) with no runtime or e2e impact, so it is intentionally not synced — the green e2e-mock run at 630c49d remains the authoritative verification.

Notes

  • Stacked base: stacks on feat(task): orchestrator new_task thinking_effort #1355; standalone review range is f6410bb68...HEAD (e2e files only).
  • runTest.ts is strictly additive (1 import + 1 fixture-registration call) and required for deterministic mock registration — explained in the body.
  • CodeRabbit findings on this PR (commit 4f88bce): the effort proxy's upstream allowlist could only ever allow loopback targets (a live ANTHROPIC_API_KEY run without AIMOCK_URL would throw for the one non-local upstream the suite intentionally supports) — the guard now allows the two intended targets explicitly (http://127.0.0.1 loopback and https://api.anthropic.com), and the aria-label/option labels of the mirrored selector now use the translated settings:providers.reasoningEffort.* keys. Both threads are resolved; the green e2e-mock run at 471490b covers the allowlist change.
  • Environment note: local runTest cannot start on the dev host (VS Code launch failure); the CI e2e-mock job is the authoritative e2e verification, and it is green at the final head.
  • Scoped e2e-package checks green: check-types exit 0, eslint on the changed e2e files exit 0.
