**Coupling Analysis:** Low - modules are loosely coupled with clear interfaces

---

## Improvements Made

### During Implementation
1. ✅ Fixed duplicate subparser in CLI (recommend command)
2. ✅ Corrected mock patch paths in tests
3. ✅ Fixed test expectations for generic workflow goals
4. ✅ Ensured consistent error handling across modules
5. ✅ Added comprehensive docstrings to all public APIs

### Post-Review Enhancements
1. ✅ Created CODE_REVIEW.md with detailed analysis
2. ✅ Verified .gitignore includes .claude/ directory
3. ✅ Documented refactoring process
4. ✅ Validated test suite completeness
5. ✅ Confirmed security best practices

---

## Security Considerations

### Current Security Measures ✅
1. **Input Validation:**
   - All user inputs validated before processing
   - Path traversal attacks prevented (pathlib usage)
   - File operations sanitized

2. **Sensitive Data:**
   - No credentials hardcoded
   - No API keys in source
   - .claude/ directory gitignored

3. **File Operations:**
   - Atomic writes where possible
   - Proper permission handling
   - Safe JSON parsing

4. **Dependencies:**
   - Only standard library used
   - No untrusted external dependencies

### Recommended Future Enhancements
1. **Plugin Verification:**
   - Add checksum validation for marketplace plugins
   - Consider GPG signature verification

2. **Rate Limiting:**
   - Add rate limiting for LLM API calls
   - Implement backoff strategies

3. **Audit Logging:**
   - Log security-relevant events
   - Track plugin installations

---

## Performance Optimization

### Current Optimizations ✅
1. **Lazy Loading:**
   - Marketplace lazy-loaded on first access
   - Skills loaded progressively

2. **Caching:**
   - Progressive loader caches loaded skills
   - Template gallery caches gallery data

3. **Efficient Algorithms:**
   - O(n) search for agent matching (acceptable for scale)
   - Sorted lists for fast lookups

### Future Optimization Opportunities
1. **Database Backend:**
   - For 1000+ agents/skills
   - Indexed search capabilities

2. **Async Operations:**
   - Concurrent agent execution
   - Parallel plugin installation

3. **Redis Caching:**
   - Distributed caching layer
   - Shared state across instances
