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.

Additional Notes

This PR intentionally changes only system-owned guidance. User-provided custom mode prompts, global instructions, and other user-authored content are preserved verbatim.

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.

Signed-off-by: JunyongParkDev <jun94.park@samsung.com>
Pass the effective tool set into system prompt sections so Zoo-owned
guidance only references callable tools.

Conditionally adapt Architect and Ask defaults, surface active edit
restrictions, and leave user-authored mode and global instructions
unchanged.

Signed-off-by: JunyongParkDev <jun94.park@samsung.com>
Resolve tool availability once per request and reuse it for the system
prompt, API metadata, runtime validation, and context condensation.

Snapshot the mode and MCP policy used for the request, and build previews
from the same effective policy to prevent prompt/runtime drift.

Signed-off-by: JunyongParkDev <jun94.park@samsung.com>
Thread effective tool names through generated environment details and
remove list_files and update_todo_list hints when those tools are
unavailable.

Reuse the prepared policy for normal requests, resumed tasks, and manual
or automatic condensation, with focused regression coverage.

Signed-off-by: JunyongParkDev <jun94.park@samsung.com>
Add table-driven coverage for Code, Debug, Architect, Ask, and
Orchestrator.

Assert each built-in mode's command, read, list, and edit capabilities so
future policy changes cannot silently reintroduce unavailable tool
guidance.

📝 Walkthrough

Summary by CodeRabbit

  • New Features
    • Tool availability is now consistently applied across prompts, requests, environment details, and execution.
    • Generated guidance adapts to enabled tools, including file editing, commands, MCP operations, planning, and completion.
    • Required workflow tools remain available where needed.
    • MCP tools respect request-specific and global disablement settings.
  • Bug Fixes
    • Disabled or unavailable tools are no longer advertised or suggested.
    • Improved validation and fallback behavior for excluded tools.
    • Added cached-model fallback when full model details cannot be retrieved.

Walkthrough

The change introduces a request-scoped effective tool policy. Tool filtering, prompt generation, environment details, API metadata, preview generation, and runtime validation now use the same canonical tool set.

Changes

Effective tool policy

Layer / File(s) Summary
Tool policy contracts and filtering
src/core/prompts/types.ts, src/core/prompts/tools/*, src/core/task/build-tools.ts, src/shared/tools.ts, src/core/tools/validateToolUse.ts
Tool filtering now returns canonical effective tool names. Disabled tools, model exclusions, MCP settings, mode groups, and required lifecycle tools are applied consistently.
Tool-aware prompt composition
src/core/prompts/sections/*, src/core/prompts/system.ts, src/core/environment/*, src/core/prompts/responses.ts
Prompt sections and environment responses now omit guidance for unavailable tools. Built-in Architect and Ask instructions adapt to available tools.
Shared request resolution
src/core/task/Task.ts, src/core/webview/generateSystemPrompt.ts
Task requests resolve tools, prompt context, API metadata, environment details, and preview generation from one request policy.
Runtime policy enforcement
src/core/assistant-message/presentAssistantMessage.ts, src/core/tools/mcpServerRestriction.ts
Runtime validation prefers the request policy. Unavailable MCP and native tools produce tool errors without execution.

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

Merge Risk: 🟡 Moderate · up to 9efcb

This PR centralizes tool availability across prompts, declarations, and runtime checks, but retries can recompute permissions during one logical request and retained mutable state can allow stale authority to affect validation. Unknown mode values also fail prompt generation instead of falling back to the default mode, creating a bounded default-behavior failure; these issues need explicit owner acceptance or follow-up before merge.

Explanation

The changes satisfy issue #1240 by sharing the effective tool policy across prompt generation, API declarations, runtime validation, previews, and context condensation. They also preserve user-authored instructions, handle MCP and Gemini behavior, retain required lifecycle tools, and prevent unavailable tools from appearing in guidance or environment details.

Full details: Out of Scope Changes check

Explanation

The implementation and regression tests remain focused on issue #1240. The prompt, tool-policy, validation, environment-detail, preview, and related task changes directly support the stated requirements.

Full details: Regression Evidence

Explanation

The new SYSTEM_PROMPT skill gating lacks focused coverage. src/core/prompts/system.ts:119-123 now skips getSkillsSection when promptContext.availableToolNames excludes skill. The changed prompt tests pass undefined as skillsManager in generatePromptWithTools, so they cannot observe this branch. The only non-empty skills test exercises getSkillsSection directly and does not pass through SYSTEM_PROMPT. No other focused test combines a populated skills manager with a context that excludes skill.

Resolution

Add a SYSTEM_PROMPT test with a mock skills manager that returns at least one skill. Pass a SystemPromptContext whose availableToolNames excludes skill, then assert that the result omits the available-skills section and that getSkillsForMode is not called. Also cover the enabled case in the same integration layer to confirm that the section remains present when skill is included.

Full details: Trust And Persistence Invariants

Explanation

No changed path meets the stated failure conditions. Complete tool calls are validated against the request policy before dispatch. MCP calls also pass ensureMcpServerAllowed before approval and execution. The changed persistence paths retain await on history saves and overwrites, and the diff adds no new non-atomic write or unmanaged lifecycle resource. Required lifecycle tools are explicitly preserved by policy, not silently bypassed.

No actionable finding. includedTools only gates custom tools. use_mcp_tool is a regular member of the mcp group, so its validation does not require the canonical name in effectiveToolNames.

Exercise reduced and restricted tool sets across prompt sections, environment details, MCP filtering, and system prompt previews.

Remove unreachable prompt fallbacks and align the tool requirement type with its existing boolean-disable behavior so each policy path is directly testable.

Signed-off-by: JunyongParkDev <jun94.park@samsung.com>
Verify native and MCP tool validation against request snapshots, live-state fallbacks, mode resolution, model inclusions, and custom mode descriptions.

Cover delegation resume, MCP hub failure handling, resolved policy reuse, allowlist snapshots, and Gemini context-management metadata.

In `@src/core/prompts/sections/__tests__/system-info.spec.ts`:
- Around line 70-73: Extend the getSystemInfoSection tests to cover the mixed
availability cases: a set containing only execute_command and a set containing
only list_files. Assert that guidance for the available tool is present and the
unrelated terminal or directory guidance is absent, while preserving the
existing all-present and all-absent coverage.

In `@src/core/prompts/system.ts`:
- Line 75: Update the mode resolution before getModeConfig so unknown mode slugs
fall back to defaultModeSlug instead of throwing. Use the resolved mode for
getModeConfig and all subsequent mode-dependent calculations while preserving
behavior for recognized modes.

885-885: 📐 Maintainability & Code Quality

No change needed: pWaitFor is mocked.

Task.spec.ts hoists vi.mock("p-wait-for", ...), whose default export is a vi.fn(). The imported pWaitFor is therefore a runtime mock, so mockRejectedValueOnce() applies correctly.

72-80: Add the missing no-context regression case.

The added case covers the context-present path only. Add a test that calls getBuiltInModeInstructions("architect", instructions) without a context and asserts that it returns instructions.

As per coding guidelines, cover unset/default cases when defaults could hide omissions. As per path instructions, add regression coverage at the lowest valid test layer.

Cover partial and unset prompt contexts, required lifecycle tools, and MCP filtering boundaries highlighted during review.

Move the request-policy equality assertion outside the swallowed streaming error path so the test fails reliably when the values diverge.
