Description

This PR makes the effective request tool policy the source of truth for system-owned prompt guidance, API tool declarations, and runtime validation.

  • Resolves the canonical effective tool set after applying mode restrictions, disabled tools, model-specific exclusions, feature availability, and MCP settings.
  • Includes command, file, editing, MCP, planning, and mode-specific guidance only when the corresponding tool is effectively available.
  • Preserves user-authored custom instructions without rewriting references to unavailable tools.
  • Keeps required lifecycle tools available, including ask_followup_question, attempt_completion, and Orchestrator's new_task.
  • Uses the same resolved policy for normal requests, prompt previews, runtime validation, and manual or automatic context condensation.
  • Allows Gemini providers to retain compatibility tool declarations while restricting their logical tool set through allowedFunctionNames.
  • Prevents environment_details from advertising list_files or update_todo_list when those tools are unavailable.

Reviewers should pay particular attention to the separation between provider compatibility declarations and logical tool availability, as well as the request-scoped policy snapshot used during tool validation.

Get in Touch

Build a canonical request-scoped tool set after mode restrictions,
feature flags, user-disabled tools, model include/exclude rules, and MCP
availability are applied.

Keep lifecycle tools required for completion and orchestration available,
and separate Gemini compatibility declarations from the logical names
the model may invoke.

Walkthrough

Changes

Effective tool policy

Layer / File(s) Summary
Build effective tools
src/core/task/build-tools.ts, src/core/prompts/tools/*, src/shared/tools.ts, src/utils/mcp-name.ts, src/core/task/__tests__/*
Tool filtering now accounts for modes, aliases, disabled tools, model restrictions, lifecycle requirements, and MCP availability. Lossless MCP identities distinguish names that provider normalization can collide.
Reuse request tool policy
src/core/task/Task.ts, src/core/task/__tests__/Task.spec.ts
Task request paths resolve tools once and reuse effective names, modes, MCP restrictions, provider declarations, and request metadata.

Tool-aware prompt and environment output

Layer / File(s) Summary
Compose tool-aware prompts
src/core/prompts/types.ts, src/core/prompts/sections/*, src/core/prompts/system.ts, src/core/prompts/__tests__/*
Prompt sections now conditionally describe available tools, mode instructions, edit restrictions, MCP operations, skills, and completion guidance.
Gate environment and file guidance
src/core/environment/*, src/core/prompts/responses.ts, src/core/environment/__tests__/*, src/core/prompts/__tests__/responses-rooignore.spec.ts
Environment and truncated file-list responses omit unavailable list_files and update_todo_list guidance.

Runtime tool validation

Layer / File(s) Summary
Validate unavailable and required tools
src/core/tools/validateToolUse.ts, src/core/tools/mcpServerRestriction.ts, src/core/tools/__tests__/*
Validation supports explicit disablement while preserving tools required by the active mode. MCP server restrictions use the current request policy when available.
Validate assistant tool calls
src/core/assistant-message/presentAssistantMessage.ts, src/core/assistant-message/__tests__/*, src/core/tools/UseMcpToolTool.ts
Native MCP and standard tool calls use request-scoped modes, experiments, effective names, unavailable-tool requirements, and normalized MCP matching.

Prompt preview

Layer / File(s) Summary
Apply restrictions to prompt preview
src/core/webview/generateSystemPrompt.ts, src/core/webview/__tests__/ClineProvider.spec.ts
Prompt preview builds restricted tools, resolves model metadata, and passes effective tool names to system-prompt generation.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 107d6

The PR centralizes tool-policy behavior, but context condensing can still omit required Gemini tool declarations and cause follow-up requests to fail; MCP authorization may also fall back to unrestricted server access if the request policy is unavailable. These bounded correctness and security risks should be fixed or explicitly accepted before merge.

Explanation

The title is concise and directly related to the main change: applying a tool policy to system-prompt generation. It is somewhat broad because the changes also cover API declarations and runtime validation, but it remains clear and relevant.

Full details: Linked Issues check

Explanation

The changes address the linked issue objectives. They centralize the effective request tool policy across prompts, API tool construction, previews, runtime validation, and context condensation; gate system-owned guidance by logical tool availability; preserve user-authored instructions; handle MCP and Gemini compatibility behavior; preserve required lifecycle tools; and add focused regression coverage.

Full details: Out of Scope Changes check

Explanation

The reviewed changes are within scope for issue #1240. Environment-detail filtering, MCP identity handling, request-scoped validation, and expanded tests directly support consistency between effective tool availability and prompt or runtime behavior. No unrelated code changes are evident.

Full details: Regression Evidence

Explanation

Focused coverage is incomplete for two distinct effective-tool prompt paths. getCapabilitiesSection added separate handling for codebase_search and access_mcp_resource in src/core/prompts/sections/capabilities.ts:60-65. The direct tests in src/core/prompts/__tests__/sections.spec.ts:126-137 cover only search_files, and the MCP test covers only a dynamic mcp--... name. A regression that omits codebase_search or resource-only MCP access would pass. codebase_search is an independent tool in the read group, and resource-only MCP access is an explicit acceptance scenario. In addition, build-tools.ts:142-175 now keeps raw MCP definitions for the Gemini compatibility path while excluding them from the logical set when mcpEnabled is false. The compatibility test uses an empty MCP hub, while the global-disable test does not enable includeAllToolsWithRestrictions, so this changed provider/logical split has no focused combined coverage.

Resolution

Add focused lowest-layer tests. In src/core/prompts/__tests__/sections.spec.ts, call getCapabilitiesSection with availableToolNames: new Set(["codebase_search"]) and assert the search capability, and call it with availableToolNames: new Set(["access_mcp_resource"]) plus a connected MCP hub and assert the MCP capability. In src/core/task/__tests__/build-tools.spec.ts, add a Gemini-style includeAllToolsWithRestrictions: true case with a populated MCP hub and mcpEnabled: false; assert the intended result explicitly: compatibility tool definitions are present or absent according to the product contract, while the dynamic MCP identity is absent from effectiveToolNames and allowedFunctionNames.

Full details: Trust And Persistence Invariants

Explanation

Global MCP disablement does not prevent MCP metadata from leaving the extension on Gemini requests. In src/core/task/build-tools.ts:144-175, mcpTools becomes empty when mcpEnabled === false, but the includeAllToolsWithRestrictions branch still builds allTools from allMcpTools. Task.attemptApiRequest enables that branch for Gemini at src/core/task/Task.ts:4377-4384, and src/api/providers/gemini.ts:276-280 serializes each MCP tool name, description, and schema into the provider request. A disabled MCP server whose tool description or name contains a secret or PII therefore still sends that data to Gemini. The base implementation used the filtered mcpTools collection in this branch.

Resolution

When mcpEnabled === false, exclude MCP definitions from the allTools compatibility array as well as from filteredMcpTools, for example by using mcpEnabled === false ? [] : allMcpTools in the includeAllToolsWithRestrictions branch. Add a regression test with includeAllToolsWithRestrictions: true and mcpEnabled: false that asserts no MCP definitions or MCP identities are returned.

Inline comments:
In `@src/core/prompts/tools/__tests__/filter-tools-for-mode.spec.ts`:
- Line 267: Extend the tests around the disabledTools case in the filter-tools
test suite to cover global MCP disablement when either disabledTools or
modelInfo.excludedTools contains “use_mcp_tool”; assert that both inputs produce
an empty tool list, while preserving the existing single-MCP-declaration removal
coverage.

In `@src/core/task/__tests__/build-tools.spec.ts`:
- Around line 92-94: Update the set assertions in
src/core/task/__tests__/build-tools.spec.ts at lines 92-94, 112-113, 129,
154-156, 170, and 186 to use effectiveToolNames.has(...) with the appropriate
negation, while retaining toContain for allowedFunctionNames. Update
src/core/task/__tests__/Task.spec.ts at lines 607 and 631-632 to assert
promptContext?.availableToolNames?.has(...), preserving the intended positive or
negative expectations.

In `@src/core/task/__tests__/Task.spec.ts`:
- Line 933: Add a nearby comment at the `task.attemptApiRequest` call explaining
that the cast is required because `TestPromptTools` does not match the private
`ResolvedPromptTools` shape, and replace the misleading `as never` cast with the
appropriate options-object cast while preserving the test behavior.

In `@src/core/task/Task.ts`:
- Around line 2864-2873: Update initiateTaskLoop so the resolvePromptTools call
is executed within the existing guarded request flow, or handle its rejection
locally before returning. Ensure provider or MCP resolution failures still
complete the request with the appropriate cost and cancellation/error state,
including the api_req_started lifecycle message.

Complete api_req_started with zero cost and streaming failure metadata when model or tool policy preparation fails, preventing the chat loading state from remaining active.

Address review coverage for global MCP exclusions, request-scoped custom tool execution, skill gating, Architect numbering, and Set-valued policy assertions.

@github-actions github-actions Bot removed the awaiting-author PR is waiting for the author to address requested changes label Sep 1, 2026
Allow the standard use_mcp_tool compatibility call through request policy validation when the snapshot contains dynamic MCP tools, so server- and tool-specific checks can report actionable errors.

Keep the wrapper blocked when no MCP tools are available and cover both branches with focused runtime tests.

Validate the resolved MCP server and tool against the request-scoped effective tool set before approval or execution, closing the compatibility-wrapper exclusion bypass.

Preserve specific unknown-server errors and cover allowed fuzzy names plus excluded sibling tools.

- Around line 350-351: Add a focused test in the “request tool policy” suite for
an unset getCurrentRequestToolPolicy() result, verifying the MCP tool request
still receives approval and callTool executes. Keep the existing
populated-policy coverage unchanged and explicitly preserve the compatibility

canonicalToolName to use a normalized, non-truncated server/tool identity, while
retaining the 64-character alias only for provider compatibility. Ensure
effective-tool-set validation compares the full identity, and add a regression
test covering distinct long tool names that collide after truncation.

Keep provider-compatible 64-character aliases while snapshotting untruncated MCP identities for request authorization, preventing colliding long names from bypassing the wrapper policy.

Cover both policy construction and execution-time rejection for alias collisions.

double assertion is unavoidable, add a nearby explanation documenting why it is
necessary.

In `@src/core/tools/UseMcpToolTool.ts`:
- Line 84: Update the MCP tool lookup in UseMcpToolTool to compare each tool
name with canonicalToolName using exact equality instead of toolNamesMatch,
preventing hyphen/underscore collisions from passing policy checks. Add a
regression test covering distinct tools such as read_file and read-file.

In `@src/utils/mcp-name.ts`:
- Around line 127-130: Update the authorization identity construction near
sanitizeMcpName so distinct valid MCP tool names, including dotted and undotted
names, remain collision-free via lossless encoding; do not change
buildMcpToolName’s separate sanitized/truncated provider-name behavior. Add

163-169: 🎯 Functional Correctness

No change needed: filterMcpToolsForMode preserves tool identity.

The function returns mcpTools.filter(...), which retains the original ChatCompletionTool objects. Its other branches return an empty array. The Map lookup therefore uses the same object references.

Inline comments:
In `@src/core/prompts/__tests__/sections.spec.ts`:
- Around line 113-123: Add regression cases covering both MCP-operation forms in
both prompt sections: extend the getCapabilitiesSection tests with a positive
access_mcp_resource case, and extend the getRulesSection tests with a positive
dynamic mcp--... tool case. Keep behavior-focused assertions and preserve the
existing negative coverage.

In `@src/core/prompts/sections/__tests__/objective.spec.ts`:
- Around line 62-69: Add independent coverage around getObjectiveSection for
question-only and completion-only availableToolNames sets, asserting each output
includes its corresponding guidance and excludes the other; retain the existing
combined-tools case as appropriate.

In `@src/core/prompts/sections/__tests__/tool-use-guidelines.spec.ts`:
- Around line 46-55: Add a test case alongside the existing parameterized
omission coverage for availableToolNames containing both “list_files” and
“execute_command”; assert that getToolUseGuidelinesSection includes the
list-files comparison text “running a command like `ls`”.

In `@src/core/task/__tests__/build-tools.spec.ts`:
- Line 160: Add a focused test alongside “excludes MCP operations when MCP is
globally disabled” that uses createMcpHub(true) while omitting mcpEnabled, then
assert access_mcp_resource and buildMcpToolIdentity("test-server", "test-tool")
are available.

In `@src/core/task/__tests__/Task.spec.ts`:
- Line 935: Document both unavoidable double assertions in getMcpHubForPrompt
tests: at src/core/task/__tests__/Task.spec.ts lines 935-935, add a nearby
comment explaining that McpServerManager.getInstance is typed to resolve a
non-nullable McpHub and the assertion enables the failure branch; at lines
952-952, explain that the { isConnecting: true } structural double implements
only the member getMcpHubForPrompt reads.

In `@src/core/task/Task.ts`:
- Line 1734: Update both resolvePromptTools call sites in src/core/task/Task.ts
at lines 1734 and 4214 to pass includeAllToolsWithRestrictions when
apiConfiguration.apiProvider is Gemini, preserving every Gemini tool declaration
during condensing. Do not add allowedFunctionNames, since GeminiHandler
intentionally ignores it.

In `@src/utils/__tests__/mcp-name.spec.ts`:
- Around line 203-205: Add a boundary-case assertion in the buildMcpToolIdentity
tests where characters shift between the server and tool segments, verifying the
resulting identities remain distinct due to length-prefix encoding. Keep the
existing hyphen/underscore assertion unchanged.

resumeAfterDelegation() is awaited by reopenParentFromDelegation(), and AttemptCompletionTool.execute() catches the propagated rejection through handleError. The transition also sets the parent to active before resuming, so the parent is not left in delegated state.

Cover both MCP-operation inputs in both prompt sections.

getCapabilitiesSection is only tested with a dynamic MCP tool. getRulesSection is only tested with access_mcp_resource. A regression in the untested operand of either hasMcpOperations expression will pass.

Add an access_mcp_resource positive case for capabilities. Add a dynamic mcp--... tool positive case for rules.

As per path instructions, “Require regression coverage at the lowest valid harness with behavior-focused assertions, including relevant negative, error, false/unset, and boundary cases.”

Test question and completion guidance independently.

This test enables ask_followup_question and attempt_completion together. It cannot detect an implementation that incorrectly requires both tools before emitting either instruction.

Add a question-only case and a completion-only case. Assert that each result contains only its corresponding guidance.

Preserve all Gemini tool declarations during condensing.

When apiConfiguration.apiProvider === providerIdentifiers.gemini, both condensing paths omit includeAllToolsWithRestrictions. resolvePromptTools therefore returns only mode-filtered tools, and GeminiHandler sends those entries as functionDeclarations. A history tool_use for a filtered tool can then be undeclared and Gemini may reject the request. Pass the Gemini flag at both Task.ts:1734 and Task.ts:4214. Do not add allowedFunctionNames; GeminiHandler intentionally ignores it.
