Summary

attempt_completion is the only way a task can finish. On current main, a single entry naming it in the disabledTools setting removes the tool from prompt generation and API declarations and makes runtime validation reject every call, so the task can never complete.

This change makes such an entry have no effect: attempt_completion stays in the prompt, in the declarations, and callable at runtime. The user's stored configuration is never rewritten; instead the user sees exactly one in-task system notice per new task naming the ignored entries (duplicates collapsed). Resuming a task does not re-emit the notice.

The other six always-available tools (ask_followup_question, switch_mode, new_task, update_todo_list, run_slash_command, skill) remain blockable through disabledTools as before. Model-profile excludedTools behavior is unchanged: a profile exclusion still strips attempt_completion from prompt and runtime alike.

Why prompt and validation cannot disagree

Prompt generation, API tool declarations, and runtime validation all read the same resolved effective tool policy. The resolver now partitions protocol-tool entries out of the user's disabledTools list once, at policy entry, before any filtering step runs, and the same effective list feeds both the tool-set computation and the runtime requirements. No consumer is left that re-derives the old precedence, so the advertised set and the accepted set agree by construction.

Tests

  • Targeted src suites covering the tool policy, prompt filter, runtime validation, and task startup: 140 passed, 0 failed.
  • Tool-execution and notice specs (presentAssistantMessage spec, the new Task ignored-disabled-tools notice spec): 17 passed, 0 failed.
  • Webview: new notice component spec (1 passed) and the chat component suite (439 passed), 0 failed.
  • Typecheck exits 0 for packages/types, src, and webview-ui.
  • Translation completeness check exits 0: the two new notice keys are present in all 17 non-English locales (machine-quality strings; native-speaker review is a follow-up).

Closes #1640

A disabledTools entry naming attempt_completion removed the completion
tool from prompt generation and API declarations, and runtime
validation rejected every call, so a task could never finish.

The effective tool policy now partitions such entries out of the
user's disabledTools list once, at policy entry, before any filtering
step, and surfaces the ignored entries as a single in-task notice per
new task. Prompt generation, API declarations, and runtime validation
all derive from the same resolved policy, so they cannot disagree
about which tools are callable. Stored configuration is left
byte-untouched. The other always-available tools remain blockable,
and a model-profile excludedTools entry still strips
attempt_completion.

Code comments that stated the old precedence are corrected
(comment-only).

📝 Summary

Summary by CodeRabbit

  • New Features

    • Chat now warns when settings list tools that cannot be disabled, naming the affected tools. The warning is available in supported languages.
  • Bug Fixes

    • User settings no longer disable protocol tools such as completion; regular disabled tools remain excluded.
    • Model exclusions can still suppress protocol tools.

Walkthrough

User disabledTools entries that name protocol tools are now ignored during policy resolution. Model-profile exclusions still suppress those tools. New tasks emit a warning for ignored entries, and chat displays the warning using localized text.

Changes

Protocol Tool Disablement

Layer / File(s) Summary
Policy resolution and requirements
packages/types/src/global-settings.ts, src/core/prompts/tools/effective-tool-policy.ts, src/core/prompts/tools/filter-tools-for-mode.ts, src/core/assistant-message/presentAssistantMessage.ts
Protocol-tool entries are partitioned out before policy and runtime requirements are built. Model excludedTools entries can still suppress protocol tools.
Policy and execution validation
src/core/prompts/tools/__tests__/*, src/core/assistant-message/__tests__/presentAssistantMessage-custom-tool.spec.ts, src/core/task/__tests__/build-tools.spec.ts, src/core/tools/__tests__/validateToolUse.spec.ts
Tests verify that user-disabled attempt_completion remains advertised and callable, while regular disabled tools and model exclusions remain effective.
Ignored-tool warning emission
src/core/task/Task.ts, src/core/task/__tests__/Task.ignored-disabled-tools-notice.spec.ts
New-task startup emits a non-interactive warning with ignored tool names. Tests cover fresh-start inputs and confirm that resume does not emit the warning.
Warning rendering and localization
packages/types/src/message.ts, webview-ui/src/components/chat/*, webview-ui/src/i18n/locales/*/chat.json
The new message type renders a localized warning when ignoredTools contains a non-empty array of strings. All listed chat locales receive title and message-template entries.

Merge Risk: 🔵 Low · up to 202a0

Ignored disabledTools entries for protocol tools now behave as intended. One minor robustness gap remains: a failure while reading state for the notice could block a new task from starting. Fix it before or soon after merge.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 202a0

The exemption is narrowly limited to task completion, while other tool restrictions and existing completion checks remain effective. A new failure path can prevent a task from starting if retrieving settings for the informational notice fails.

Retained concerns

  • Low · reliability · inferred: The informational notice introduces an unconditional settings-read dependency into task launch. A rejection after earlier initialization succeeds exits before isInitialized and task-loop initiation, while constructor/start paths only log the failure and leave _started set; run retains its failed promise. This adds a failure-containment and recovery gap even for tasks with no ignored entries. Earlier state reads already existed, so the introduced exposure is failure at this additional read, not every settings failure.
Security review details

Security Blast Radius

  • inferred — The newly reachable operation affects completion of the current task and, for delegated tasks, continuation of its associated parent. It does not re-enable terminal, filesystem or MCP tools through disabledTools. Completion retains checks for prior tool failure, required result content and optionally unfinished todos.

Trust Boundaries and Controls

  • observed — Completion remains subject to the existing acceptance path. Delegated completion passes through an approval callback and checks that the parent awaits this child; the provider revalidates ownership and cancellation after the asynchronous approval gap.
  • observed — The notice consumer validates its JSON payload and renders the localized result as React text. The new branch supplies no external link or action callback, so ignored-tool names do not introduce executable markup or tool authority through this rendering path.

Resilience and Maintainability Implications

  • observed — The inherited delegated-completion transition serializes work by parent, verifies pending-action identity, atomically updates child and parent lifecycle records, and rechecks cancellation and current-instance ownership before scheduled continuation. Pending-action recovery returns through approval rather than automatically reopening the parent. These controls predate this PR and remain on the newly reachable completion path.

Hardening Proposals

  • proposed — Contain informational-notice retrieval failures separately from task launch, or provide an explicit recoverable launch-failure state. This should preserve the shared effective authorization policy rather than create a fallback that weakens execution restrictions.

Explanation

The new chat warning lacks the required Playwright snapshot. ChatRowContent now renders a visible WarningRow for ignored_disabled_tools_warning (webview-ui/src/components/chat/ChatRow.tsx:1593-1609). The added IgnoredDisabledToolsNotice.spec.tsx checks rendered text and invalid payload branches, but no matching .visual.tsx test or notice snapshot exists. The webview test guidance requires a Playwright snapshot for user-noticeable UI changes (webview-ui/AGENTS.md:46-57).

The patch-coverage check flagged two untested branches in the ChatRow case
that renders the ignored disabled-tools notice: the row renders nothing when
the message carries no text, and when the stored payload is not valid JSON.
Add spec cases for both so every render path of the notice is covered.

Follow-up to PR review feedback on the attempt_completion exemption.

presentAssistantMessage-custom-tool.spec.ts asserted only that
attemptCompletionTool.handle was called for a disabled
attempt_completion entry. The assertion now also pins the arguments:
the task, the attempt_completion tool-use block, and the callback
object including its toolCallId.

ChatRow rendered the ignored disabled-tools warning by calling join on
the parsed ignoredTools field after only a truthy check, so a
corrupted persisted payload (a string, or an array containing
non-strings) threw during render. The field is now treated as unknown
and the row renders nothing unless it is a non-empty array of strings.
Three regression tests in IgnoredDisabledToolsNotice.spec.tsx cover
those payload shapes.

The translation mock in IgnoredDisabledToolsNotice.spec.tsx now types
its options parameter as Record<string, unknown> instead of
Record<string, any>.

Follow-up to PR review feedback on Zoo-Code-Org#1751.

The notice that a disabled attempt_completion entry is ignored was
only pinned on the new-task path: the spec drove startTask and
asserted exactly one ignored_disabled_tools_warning message. The
documented behavior that resuming a saved task does not re-emit the
notice had no test.

Task.ignored-disabled-tools-notice.spec.ts now also drives
resumeTaskFromHistory for a history item whose profile lists
attempt_completion in disabledTools. The new test asserts that no
ignored_disabled_tools_warning message is said during the resume,
next to liveness checks (the resume_task ask is issued and the task
loop starts once) so a silent early return cannot pass as a
zero-notice result. The provider fixture was extracted from the
startTask helper so both paths share it; the existing new-task
assertions are unchanged.

If the active model profile's excludedTools also names attempt_completion, the tool is still stripped, but this notice says it "will remain available". Should the notice avoid the availability claim, or be skipped when the profile also excludes the tool?

This test compares policy.tools with the buildToolRequirements map, but nothing passes that map to the real validateToolUse or isToolAllowedForMode. Would a table test in validateToolUse.spec.ts that feeds buildToolRequirements output to the real validator catch drift between the two?

Follow-up to PR review feedback on Zoo-Code-Org#1751.

The notice telling the user that a disabled attempt_completion entry
was ignored claimed the tool "will remain available". That is false in
one state: when the active model profile's excludedTools also names the
tool, the effective policy still strips it, so the notice overpromised.
The profile-level excludedTools veto is intentional behavior, so the
copy changed rather than the policy.

messageTemplate now only states why the entry was ignored: "The
following tools cannot be disabled, so their disabledTools entries were
ignored: {{tools}}." The string is updated in all 18 locale chat.json
files; every locale currently replicated the false claim, so an en-only
edit would leave 17 of them asserting it. Task.ts detection and
emission are untouched, and {{tools}} is byte-preserved everywhere.

Two test changes lock in the fix. In
IgnoredDisabledToolsNotice.spec.tsx the two assertion strings move to
the new copy and a regression test renders the notice and fails if any
availability wording reappears (6 tests to 7). validateToolUse.spec.ts
gains a builder/validator agreement table: real buildToolRequirements
output driven through the real isToolAllowedForMode and validateToolUse
across six rows, including the overlap case where both lists name
attempt_completion and the profile veto wins. Additions only; every
pre-existing test is byte-identical (27 tests to 33).

Thanks for the review. Both nits are addressed in the follow-up commit: the notice copy no longer claims the tool will remain available (it now only names the ignored disabledTools entries, updated across all 18 locales), and validateToolUse.spec.ts gained a table test that feeds real buildToolRequirements output through the real validator, including the case where the profile excludedTools veto overrides the ignored disable.

Assert deduplication in the emitted notice.

The startup test supplies attempt_completion once. If notification construction stops deduplicating repeated entries, this assertion still passes. Supply the entry twice and assert that ignoredTools contains it once.

Keep the informational lookup from blocking task startup.

If getState() rejects, startTask() rethrows before isInitialized and initiateTaskLoop(), so the new task never starts. Nearby getEnabledMcpToolsCount() and initializeTaskMode() handle provider-state failures. Catch this notice-only read and continue without the warning.

ignored_disabled_tools_warning now renders a visible WarningRow, but its test only checks text in Vitest. No chat-row visual snapshot captures this notice. Add a durable *.visual.tsx snapshot for the chat screen that includes the warning.

Add a durable Playwright visual snapshot in a *.visual.tsx test for the chat
screen that renders a message with say set to ignored_disabled_tools_warning, so
the visible WarningRow is included in the snapshot.
