In `@scripts/stryker-diff.mjs`:
- Line 325: Update win32ShellQuote and its command-invocation paths so literal
percent signs in operands, including %TEMP%, are not expanded by cmd.exe while
preserving existing quoting behavior. Add Windows regression coverage for
literal %TEMP% operands in both affected paths.
In `@src/core/prompts/__tests__/sections.spec.ts`:
- Around line 347-350: Rename the test containing getRulesSection and the RULES
assertion to describe only the baseline RULES behavior; remove the misleading
isStealthModel and vendor-confidentiality wording from its test name while
leaving the assertion and implementation unchanged.
In `@src/core/prompts/sections/objective.ts`:
- Line 26: Update the objective prompt wording to replace the broad “extensive
capabilities” and “wide range of tools” claim with policy-neutral wording
referring only to the provided tools, while preserving the surrounding tool-use
guidance. Add a zero-clause policy assertion in the objective prompt tests to
verify the revised wording under a policy with no tool clauses.
In `@src/core/prompts/tools/effective-tool-policy.ts`:
- Around line 290-303: Compute the MCP resource availability once before the
`allowedToolNames` check, store the result, and reuse it for `hasMcpResources`
and related MCP-tool resolution instead of calling `hasAnyMcpResources` or
repeatedly querying `mcpHub.getServers()`. Update the surrounding logic in the
effective policy flow while preserving its existing behavior.
In `@src/core/task/__tests__/build-tools.spec.ts`:
- Line 102: Add positive expectations to both relevant tests around
allowedFunctionNames, including the assertions near execute_command and the
other referenced case, verifying the expected allowed tool name is present while
retaining the negative assertions. This must ensure the list is non-empty and
correctly populated rather than only confirming excluded names are absent.

condenseContext could still issue a summarization request, and rewrite the persisted conversation history, when the task was cancelled while the system prompt was being built or while summarization was in flight. Check for cancellation after each of those awaits and return early. Add regression tests that cancel at both points and assert that neither summarizeConversation nor overwriteApiConversationHistory runs.

The second cancellation check in condenseContext also skips summarization, so falsifying the first one left every test passing. The mutation gate caught this: two mutants on the first check survived because nothing observed the work between the two checks. Assert that a task cancelled at the first checkpoint never builds the system prompt, which is the behavior that check exists to guarantee.
The comment claimed that skipping summarization is also achieved by the checks placed after the prompt and summarize awaits. Only the check after the prompt await can hide a missing first check: the later one runs once summarization has already been called.

Remove the task-lifecycle and history-persistence work from this branch: the metadata-fetch timeout bound, the waiter-detach signal plumbing, and the post-summarization cancellation guard revert to main; that work is preserved outside the branch for a follow-up. What remains is the prompt/tool-policy change for Zoo-Code-Org#1240 and Zoo-Code-Org#505, plus two fixes the review asked for. A new builder-layer test pins that modelInfo.excludedTools excluding use_mcp_tool removes the dynamic mcp--* declarations from the sent tools, like a user-level disable. And a disabled or excluded attempt_completion now honors the tool allowlist end to end: it leaves the effective policy set and the callable allowlist, and execution rejects the call with the standard validation-error tool_result instead of completing the task.
…spec coverage Unexport hasAnyMcpResources (no external callers), make the skills section policy parameter required (the sole caller always passes one), and make the model-metadata timeout clear unconditional (the handle is always assigned). Inline the single-use SystemPromptRequest alias and drop stale comment narration. Delete prompt-spec tests that duplicated sections.spec coverage, moving the two assertions that carried unique mutation kills (empty edit-restriction description branch, terminal-output fallback tail) into the surviving sections.spec tests.

- Around line 318-320: Ensure protocol tools, including attempt_completion, are
always re-added to the allowed policy even when disabledTools or excludedTools
contains them. Exclude PROTOCOL_TOOLS when building toolRequirements, preserve
the required one-time warning for attempted protocol-tool suppression, and

- Around line 348-361: Update buildToolRequirements to mark every
modelInfo.excludedTools entry as disabled in the requirements map, including
each tool’s canonical name and aliases, while preserving the existing disabled
and protocol-tool handling. Add a regression covering validation of a tool call
whose native declaration was omitted because the ordinary tool is excluded,
ensuring it is rejected before execution.
In `@src/core/task/Task.ts`:
- Line 4301: Update Task.safeEnsureModelFetched() around ensureModelFetched() to
race metadata fetching against a 5-second timeout; when the timeout wins, return
this.api.getModel().info, while preserving the fetched metadata result when it
completes first and allowing cancellation/request construction to proceed.
- Around line 1861-1862: In condenseContext, re-add a cancellation/abandonment
guard after summarizeConversation returns and before calling
overwriteApiConversationHistory. Ensure aborted or abandoned tasks do not
replace or persist conversation history, while non-cancelled flows retain the

- Around line 4518-4526: Update attemptApiRequest(), getSystemPrompt(), and
buildNativeToolsArrayWithRestrictions() to capture one request-level snapshot of
the task mode and effective MCP availability before any MCP or rate-limit wait.
Pass that snapshot through prompt generation and native tool construction,
ensuring both paths use the same mode and that MCP declarations are omitted when

In `@src/core/prompts/__tests__/sections.spec.ts`:
- Around line 49-50: Update the test fixtures around makeMcpHub and the related
SkillsManager fixture to use narrow interfaces for the consumed getServers() and
getSkillsForMode() methods instead of unknown-based assertions. Type MCP server,
tool, and resource fields explicitly, add source: "global" to every
SkillMetadata fixture, and change EffectiveToolPolicyInput.mcpHub to accept the
narrow MCP interface so makeMcpHub requires no type assertion.
In `@src/core/prompts/__tests__/system-prompt.spec.ts`:
- Around line 763-771: Extend the prompt tests to cover the MCP RULES gate in
rules.ts: assert the MCP guidance sentence appears when policy.hasMcpGroup is
combined with either MCP tools or MCP resources, and is absent when the MCP
group has neither. Add these cases alongside the existing section prompt tests,
using the established prompt runner and section extraction helpers.
In `@src/core/prompts/sections/capabilities.ts`:
- Around line 50-54: The editRestrictionSuffix in the capabilities prompt must
be omitted when no effective edit tool is available, even if
policy.editRestriction remains set. Gate its generation on the resolved
edit-tool availability (or clear the restriction during resolution), and add
coverage for an edit-restricted mode with editing tools disabled.
In `@src/core/prompts/sections/objective.ts`:
- Around line 8-9: Update the objective section to emit tool-neutral completion
wording when attempt_completion is absent, while preserving its advertisement
when available. In src/core/prompts/sections/objective.ts lines 8-9, apply the
policy check; update src/core/prompts/sections/__tests__/objective.spec.ts lines
76-86 to assert omission; and update getRulesSection coverage in
src/core/prompts/__tests__/sections.spec.ts lines 351-365 to assert
attempt_completion is omitted from RULES.
In `@src/core/prompts/sections/rules.ts`:
- Around line 112-114: Update getRulesSection so the FileRestrictionError
guidance is added only when policy.tools contains at least one supported edit
tool: apply_diff, write_to_file, edit, search_replace, edit_file, or
apply_patch. Compute hasEditTools from policy.tools and gate the existing
rules.push call with it.
In `@src/core/prompts/tools/__tests__/effective-tool-policy.spec.ts`:
- Around line 42-44: Update makeMcpHub to use a narrow typed structural stub,
such as a ProviderDouble with Pick<McpHub, "getServers">, and type the server
fixtures to expose name, resources, and tools[].enabledForPrompt. Remove the as
unknown as McpHub double assertion so changes to the MCP server shape are
checked by TypeScript.
In `@src/core/prompts/tools/__tests__/filter-tools-for-mode.spec.ts`:
- Around line 320-335: Move the test for isToolDisabledOrExcluded out of the
filterMcpToolsForMode - disabledTools describe block and place it in
effective-tool-policy.spec.ts, or wrap it in a
describe("isToolDisabledOrExcluded") block. Keep the alias-resolution
assertions, but omit the separate empty-registry concern.
In `@src/core/task/__tests__/build-tools.spec.ts`:
- Around line 84-85: Add a positive assertion in the test covering
allowedFunctionNames to verify it contains "read_file", while retaining the
existing negative assertions for "attempt_completion" and "execute_command".
In `@src/core/task/__tests__/Task.spec.ts`:
- Line 4038: Move the three misplaced tests in Task.spec.ts out of
describe("safeEnsureModelFetched") into describe blocks named for the
attemptApiRequest and condenseContext subjects they exercise. Also move the
webview test out of describe("generateSystemPrompt preview parity") into a
describe block matching its direct SYSTEM_PROMPT subject, preserving each test’s
behavior.

Group each test under a describe block named for its subject. The three tests in Task.spec.ts are inside describe("safeEnsureModelFetched"), but they test attemptApiRequest and condenseContext. The webview test is inside describe("generateSystemPrompt preview parity"), but it calls SYSTEM_PROMPT directly. Move each test to a matching describe block. The repository test convention requires this naming.

Verified against current head: these tests are no longer nested under safeEnsureModelFetched; they are grouped by request-scoped parser/constructor/request-configuration responsibilities. Moving them again would add churn without changing test scope, so this organization finding is not actionable on the authoritative diff.

Nine genuinely fixed inline threads were resolved. The two remaining organization/assertion threads have evidence-backed replies because current head already satisfies them. No Zoo-Code-Docs update or visual proof is applicable because this is backend prompt/runtime correctness with no UI change. |

Model-metadata fetches (ensureModelFetched) could outlive the request that started them: a canceled task or a timed-out prompt preview left the fetch awaited, with no signal to abort it and no check before its result was persisted. This restores cancellation handling at the caller layer: - The bounded preview timeout now aborts the metadata fetch it races, instead of leaving the fetcher's promise dangling after the timeout. - Condense paths now check abort/abandoned state before starting and before persisting summarized history, with an added guard before summarization so a canceled task cannot write summarize output. - cancelCurrentRequest aborts the in-flight metadata fetch and detaches waiters, so stale promises no longer retain task state. - Adds a standalone edit-tool coverage test for prompt-section rendering (coverage gap: the tool was only exercised via combined fixtures).

- Line 790: Strengthen the pre-aborted signal test around ensureModelFetched by
spying on or mocking getModels and asserting it is not called when the signal is
already aborted, while retaining the rejection assertion. Use the existing test
harness and getModels symbol rather than adding broader coverage.

Task disposal now marks the task as aborted before it cancels the prompts that in-flight metadata fetches are waiting on. Marking the disposal synchronously means any model request that could start after cleanup begins already observes an aborted task, so no request starts after disposal. Adds a regression test for disposal racing a metadata wait, and an assertion that getModels is not called when the signal is already aborted.
…dule Coverage source population moved from 469 records / 30229 lines to 470 records / 30324 lines. The delta is attributable to src/core/prompts/tools/effective-tool-policy.ts, a production module added by this change; the remaining line growth comes from branch modifications to existing instrumented sources. No source files were removed; verified by regenerating all coverage lanes locally.

Closes: #505
Description
The problem. The system prompt and the tool definitions are built from separate sources of truth, so the prompt can advertise tools the model cannot call. In Architect, Ask, or Orchestrator mode the capabilities and rules sections describe
execute_commandalthough the mode has nocommandgroup; MCP guidance can appear when no MCP tool or resource is effectively available; and instructions can require tools thatdisabledToolsor model exclusions removed (#1240). The prompt also repeats the same file-tree paragraph inCAPABILITIESandSYSTEM INFORMATION, identical text paid for twice per request (#505).What changes. One request-scoped effective tool policy (
src/core/prompts/tools/effective-tool-policy.ts) computes the logical tool set from mode groups, custom modes,disabledTools, model included/excluded tools, feature flags, experiment state, and effective MCP availability. Prompt sections, native and MCP tool declarations, the runtime validator, and the prompt preview consume that one set, so prompt and tool definitions agree. The duplicated paragraph is removed; the remaining copy is cwd-independent. Request-scoped model metadata is threaded through retries and context-window recovery.The change also completes cancellation for the model-metadata awaits it introduces.
ensureModelFetchednow takes an optionalAbortSignal; the task request, manual condensation, and preview paths detach from the fetch on cancellation or timeout; the preview's five-second bound aborts its wait instead of only clearing the timer; cancellation is rechecked before starting a condensed summary and before persisting one. Regression tests hold each awaited fetch pending, cancel the task, and verify no later request or summarization starts. The capabilities section gained coverage for the standaloneedittool.Scope of the cancellation work. Cancellation in this change is complete at the caller layer: the task request, manual condensation, and prompt-preview paths now detach from model-metadata fetching on cancellation and timeout, with guards rechecked before starting and before persisting a condensed summary. The in-flight catalog HTTP request itself, the shared model-cache fetch and the provider HTTP calls in
src/api/providers/fetchers/, are unchanged here and are tracked separately in #1615.Related work (deliberately out of scope)
