Poem

A bunny hopped through code today,
Tidying tools in a brand new way.
With boots and lists and open doors,
The simulators now have more chores!
Old configs gone, new powers in hand—
Simulator Management takes command.

PR Review: Improve tool discovery prompt and migrate to simulator-management workflow

Review Checklist

  • Analyze the tool discovery prompt improvements
  • Review workflow migration from simulator-environment to simulator-management
  • Check test coverage and file organization
  • Verify documentation updates accuracy
  • Assess code quality and best practices
  • Look for potential bugs or security issues
  • Evaluate performance considerations
  • Provide comprehensive feedback

✅ Overall Assessment

This is a well-executed PR that improves the AI-driven tool discovery system and completes a clean workflow migration. The changes demonstrate strong attention to code quality, testing, and documentation consistency.

🌟 Strengths

1. Excellent Tool Discovery Improvements

  • Clear Primary vs Secondary Workflow Separation: The new prompt structure in discover_tools.ts (lines 163-178) effectively categorizes workflows, making it much easier for LLMs to select the correct tools
  • Enhanced User Guidance: The updated task description explicitly asks users to specify .xcworkspace vs .xcodeproj, which directly addresses common selection errors
  • Improved Prompt Engineering: The selection guide is well-structured and comprehensive, covering all major use cases

2. Clean Workflow Migration

  • Proper Re-export Pattern: All tools in simulator-management correctly re-export from simulator-shared (e.g., boot_sim.ts:2)
  • Consistent Naming: The migration from "simulator-environment" to "simulator-management" is more descriptive and intuitive
  • Complete Migration: All files and tests were properly moved without leaving orphaned references

3. Strong Test Coverage

  • Comprehensive Test Migration: All 5 test files were properly moved and updated
  • Follows Project Standards: Tests continue to use the dependency injection pattern with createMockExecutor
  • Good Test Quality: The test file I examined (sim_statusbar.test.ts) shows thorough validation patterns

4. Documentation Accuracy

  • Updated Tool Count: TOOLS.md correctly reflects 7 tools in the simulator-management workflow
  • Clear Description: The workflow description accurately describes the capabilities
  • Consistent Formatting: Documentation follows the established format patterns

🔍 Detailed Code Quality Analysis

Security Considerations

  • Input Sanitization: The sanitizeTaskDescription function (lines 38-78) provides good protection against prompt injection attacks
  • Length Validation: Proper truncation at 2000 characters prevents resource exhaustion
  • Pattern Filtering: Suspicious patterns are detected and filtered appropriately

Error Handling

  • Comprehensive Null Safety: Enhanced null checking in sampling result parsing (lines 211-328)
  • Graceful Degradation: Proper fallback when LLM responses are malformed
  • Informative Error Messages: Clear error messages that help users understand what went wrong

Code Structure

  • Good Separation of Concerns: Logic functions are separated from handlers for testability
  • Consistent Patterns: All files follow the established project conventions
  • Type Safety: Proper use of Zod schemas and TypeScript types

🐛 Issues Found

1. Test Description Inconsistency (Minor)

File: src/mcp/tools/simulator-management/__tests__/index.test.ts:7

describe('simulator-environment workflow metadata', () => {

Issue: Test description still references "simulator-environment" instead of "simulator-management"
Impact: Low - just a description mismatch, functionality is correct

2. Import Path Extension Consistency (Minor)

File: src/mcp/tools/simulator-management/boot_sim.ts:2

export { default } from '../simulator-shared/boot_sim.ts';

Issue: Using .ts extension in import (should be .js for runtime)
Impact: Low - may cause runtime issues depending on build configuration

🚀 Performance Considerations

  • No Performance Impact: The changes are primarily organizational and don't affect runtime performance
  • Improved LLM Efficiency: The clearer prompt structure should reduce token usage and improve selection accuracy
  • Maintained Tool Loading: Re-exports don't add significant overhead

📋 Test Coverage Assessment

  • Complete Migration: All 5 test files properly migrated
  • Maintained Standards: Tests continue to follow the strict dependency injection pattern
  • No Coverage Gaps: All tools have corresponding tests
  • Test Quality: Examined tests show comprehensive validation including edge cases

💡 Recommendations

1. Fix Test Description (Should Fix)

Update the test description in index.test.ts:7:

- describe('simulator-environment workflow metadata', () => {
+ describe('simulator-management workflow metadata', () => {

2. Consider Import Path Consistency (Optional)

Consider standardizing import extensions across re-export files to match the project's runtime requirements.

3. Monitor LLM Selection Accuracy (Future)

Consider tracking metrics on how often the improved prompt leads to correct workflow selection to validate the improvements.

🎯 Conclusion

This is a high-quality PR that successfully:

  • ✅ Improves the AI tool discovery system with clearer guidance
  • ✅ Completes a clean workflow migration without breaking changes
  • ✅ Maintains excellent test coverage and code quality standards
  • ✅ Updates documentation to match code changes
  • ✅ Follows all project conventions and patterns

The changes are well-thought-out, properly implemented, and ready for merge after addressing the minor test description issue.

Recommendation: Approve with the suggested minor fix

18-28: Helper signature deviates from the other tools

Here executor comes before extraValidation, whereas in reset_simulator_location.ts and set_sim_appearance.ts it is the opposite.
The inconsistency forces call-sites to remember three different orders for the same helper pattern and is an unnecessary foot-gun.

Refactor all helpers to share the same parameter order:

  1. params
  2. simctlSubCommand
  3. operationDescription
  4. successMessage
  5. failureMessagePrefix
  6. operationLogContext
  7. executor
  8. extraValidation?
♻️ Duplicate comments (5)
src/mcp/tools/simulator-management/sim_statusbar.ts (1)

2-4: Runtime resolution risk – see comment in set_simulator_location.ts

The same .ts extension change applies here. Confirm that the bundler rewrites the path or revert to .js to avoid “MODULE_NOT_FOUND”.

src/mcp/tools/simulator-management/reset_simulator_location.ts (2)

2-5: .ts extension change – same concern as previous files

Re-evaluate the import-path extension; the risk and recommendation mirror the first comment.


18-27: Parameter order inconsistency with sibling tools

This helper places extraValidation after executor, opposite to set_simulator_location.ts.
Unify for predictability (see earlier refactor suggestion).

src/mcp/tools/simulator-management/set_sim_appearance.ts (2)

2-4: .ts extension change – same concern as previous files

Ensure the bundler rewrites or revert to .js to avoid runtime resolution errors.


18-27: Helper signature diverges again

Here extraValidation precedes executor and executor has a default value, adding yet another variant.
Consolidate signatures across the three helpers.

🧹 Nitpick comments (5)
src/mcp/tools/simulator-management/set_simulator_location.ts (1)

36-68: Duplicated executeSimctlCommandAndRespond helper

Nearly identical helpers now live in three files (set_simulator_location, reset_simulator_location, set_sim_appearance).
Extract once into src/mcp/tools/simulator-shared/executeSimctl.ts and import it, to reduce maintenance cost and ensure consistent behaviour.

src/mcp/tools/simulator-management/sim_statusbar.ts (1)

63-71: Return shape differs between success and failure

isError is only set on the failure path. Down-stream consumers that rely on this flag must check for both !result.isError and result.success === undefined.

Consider always including a boolean success flag, or always setting isError.

src/mcp/tools/simulator-management/boot_sim.ts (1)

1-2: Comment wording mismatch – update for clarity

The code re-exports from simulator-shared, but the header comment still references “simulator-workspace”. Rename the comment to avoid future confusion.

-// Re-export from simulator-workspace to avoid duplication
+// Re-export from simulator-shared to avoid duplication
src/mcp/tools/simulator-management/__tests__/index.test.ts (2)

1-3: Fix comment to reflect correct workflow name.

The comment references "simulator-environment" but should reference "simulator-management" to match the actual workflow being tested.

/**
- * Tests for simulator-environment workflow metadata
+ * Tests for simulator-management workflow metadata
 */

7-7: Fix describe block name to match workflow.

The describe block still references "simulator-environment" but should reference "simulator-management" to accurately describe what's being tested.

212-214: Use a cross-platform temp path and avoid unescaped shell interpolation

Hard-coding /tmp/... limits the CLI to Unix-like hosts and string-concatenating reloaderooArgs.join(' ') into bash -c opens a door for argument-injection if this helper is ever reused with dynamic input.

-import fs from 'fs';
+import fs from 'fs';
+import os from 'os';        // ✅ portable temp directory

214-214: Confirm npx -y support in all target environments

The -y/--yes switch requires npm ≥ 7.0 (Node 14 LTS shipped with npm 6). If CI or user machines run an older npm, the CLI will exit with “unknown option” errors.

Please verify the minimal Node/npm versions in .nvmrc, package.json engines, and CI images, or gracefully fall back when the flag is unsupported.

⚠️ Potential issue

Import path now out of sync with implementation

Tests still point to utils/command.js while the implementation shifted to .ts.
This will break TS-node test runs because command.js does not exist in the source tree.

🧩 Analysis chain

.ts import extension may break the emitted ESM bundle

The project previously imported internal modules with the .js extension so that, after compilation, Node/ESM could resolve the transpiled files.
Switching to .ts will cause the compiled .js output to keep the .ts suffix in the import statement, which Node cannot resolve at runtime unless the bundler rewrites paths (tsup does not do this by default).

Please verify the bundle or revert to .js:

-import { ToolResponse } from '../../../types/common.ts';
-import { log, CommandExecutor, getDefaultCommandExecutor } from '../../../utils/index.ts';
-import { createTypedTool } from '../../../utils/typed-tool-factory.ts';
+import { ToolResponse } from '../../../types/common.js';
+import { log, CommandExecutor, getDefaultCommandExecutor } from '../../../utils/index.js';
+import { createTypedTool } from '../../../utils/typed-tool-factory.js';

🏁 Script executed:

#!/bin/bash
set -e

# Locate tsup configuration
FILE=$(fd tsup.config.ts || true)
if [[ -n "$FILE" ]]; then
  echo "Found tsup config at: $FILE"
  echo "----- tsup.config.ts (first 200 lines) -----"
  sed -n '1,200p' "$FILE"

rg -n '"tsup"' package.json || echo "No tsup reference in package.json"

Fix .ts imports to .js for ESM output

Tsup emits ESM modules without rewriting .ts extensions, so Node won’t resolve imports like …/common.ts at runtime. Update your local imports to use .js:

• File: src/mcp/tools/simulator-management/set_simulator_location.ts (lines 2–4)

-import { ToolResponse } from '../../../types/common.ts';
-import { log, CommandExecutor, getDefaultCommandExecutor } from '../../../utils/index.ts';
-import { createTypedTool } from '../../../utils/typed-tool-factory.ts';

PR Review: Improve tool discovery prompt and migrate to simulator-management workflow

Review Checklist

  • Read repository documentation and context
  • Analyze the tool discovery prompt improvements
  • Review workflow migration from simulator-environment to simulator-management
  • Check test coverage and file organization
  • Verify documentation updates accuracy
  • Assess code quality and best practices
  • Look for potential bugs or security issues
  • Evaluate performance considerations
  • Provide comprehensive feedback

✅ Overall Assessment

This is a well-executed PR that improves the AI-driven tool discovery system and completes a clean workflow migration. The changes demonstrate strong attention to code quality, testing, and documentation consistency.

🌟 Strengths

1. Excellent Tool Discovery Improvements

  • Clear Primary vs Secondary Workflow Separation: The new prompt structure in discover_tools.ts (lines 163-178) effectively categorizes workflows, making it much easier for LLMs to select the correct tools
  • Enhanced User Guidance: The updated task description explicitly asks users to specify .xcworkspace vs .xcodeproj, which directly addresses common selection errors
  • Improved Prompt Engineering: The selection guide is well-structured and comprehensive, covering all major use cases

2. Clean Workflow Migration

  • Proper Re-export Pattern: All tools in simulator-management correctly re-export from simulator-shared (e.g., boot_sim.ts:2)
  • Consistent Naming: The migration from "simulator-environment" to "simulator-management" is more descriptive and intuitive
  • Complete Migration: All files and tests were properly moved without leaving orphaned references

3. Strong Test Coverage

  • Comprehensive Test Migration: All 5 test files were properly moved and updated
  • Follows Project Standards: Tests continue to use the dependency injection pattern with createMockExecutor
  • Good Test Quality: The test file I examined (sim_statusbar.test.ts) shows thorough validation patterns

4. Documentation Accuracy

  • Updated Tool Count: TOOLS.md correctly reflects 7 tools in the simulator-management workflow
  • Clear Description: The workflow description accurately describes the capabilities
  • Consistent Formatting: Documentation follows the established format patterns

🔍 Detailed Code Quality Analysis

Security Considerations

  • Input Sanitization: The sanitizeTaskDescription function (lines 38-78) provides good protection against prompt injection attacks
  • Length Validation: Proper truncation at 2000 characters prevents resource exhaustion
  • Pattern Filtering: Suspicious patterns are detected and filtered appropriately

Error Handling

  • Comprehensive Null Safety: Enhanced null checking in sampling result parsing (lines 211-328)
  • Graceful Degradation: Proper fallback when LLM responses are malformed
  • Informative Error Messages: Clear error messages that help users understand what went wrong

Code Structure

  • Good Separation of Concerns: Logic functions are separated from handlers for testability
  • Consistent Patterns: All files follow the established project conventions
  • Type Safety: Proper use of Zod schemas and TypeScript types

🐛 Issues Found

1. Test Description Inconsistency (Minor)

File: src/mcp/tools/simulator-management/__tests__/index.test.ts:7

describe('simulator-environment workflow metadata', () => {

Issue: Test description still references "simulator-environment" instead of "simulator-management"
Impact: Low - just a description mismatch, functionality is correct

2. Import Path Extension Consistency (Minor)

File: src/mcp/tools/simulator-management/boot_sim.ts:2

export { default } from '../simulator-shared/boot_sim.ts';

Issue: Using .ts extension in import (should be .js for runtime)
Impact: Low - may cause runtime issues depending on build configuration

🚀 Performance Considerations

  • No Performance Impact: The changes are primarily organizational and don't affect runtime performance
  • Improved LLM Efficiency: The clearer prompt structure should reduce token usage and improve selection accuracy
  • Maintained Tool Loading: Re-exports don't add significant overhead

📋 Test Coverage Assessment

  • Complete Migration: All 5 test files properly migrated
  • Maintained Standards: Tests continue to follow the strict dependency injection pattern
  • No Coverage Gaps: All tools have corresponding tests
  • Test Quality: Examined tests show comprehensive validation including edge cases

💡 Recommendations

1. Fix Test Description (Should Fix)

Update the test description in index.test.ts:7:

- describe('simulator-environment workflow metadata', () => {
+ describe('simulator-management workflow metadata', () => {

2. Consider Import Path Consistency (Optional)

Consider standardizing import extensions across re-export files to match the project's runtime requirements.

3. Monitor LLM Selection Accuracy (Future)

Consider tracking metrics on how often the improved prompt leads to correct workflow selection to validate the improvements.

🎯 Conclusion

This is a high-quality PR that successfully:

  • ✅ Improves the AI tool discovery system with clearer guidance
  • ✅ Completes a clean workflow migration without breaking changes
  • ✅ Maintains excellent test coverage and code quality standards
  • ✅ Updates documentation to match code changes
  • ✅ Follows all project conventions and patterns

The changes are well-thought-out, properly implemented, and ready for merge after addressing the minor test description issue.

Recommendation: Approve with the suggested minor fix
