# Task Decomposition Summary: Prevent Comment Replacement Hook

## Decomposition Complete ✅

**Source Specification**: `specs/feat-prevent-comment-replacement-hook.md`  
**Task Breakdown Document**: `specs/feat-prevent-comment-replacement-hook-tasks.md`  
**Task Management System**: STM (Simple Task Master)  
**Date**: 2025-08-10

## Task Statistics

### Total Tasks Created: 12
- **Phase 1 (Foundation)**: 2 tasks
- **Phase 2 (Core Implementation)**: 5 tasks
- **Phase 3 (Testing)**: 2 tasks
- **Phase 4 (Integration)**: 2 tasks
- **Phase 5 (Documentation)**: 1 task

### Task IDs in STM
- Task 154: [P1.1] Create Hook Base File Structure
- Task 155: [P1.2] Define Pattern Constants
- Task 156: [P2.1] Implement Main Execute Method
- Task 157: [P2.2] Implement File and Edit Processing Methods
- Task 158: [P2.3] Implement Violation Detection Logic
- Task 159: [P2.4] Implement Pattern Matching Methods
- Task 160: [P2.5] Implement Error Formatting Method
- Task 161: [P3.1] Create Unit Tests
- Task 162: [P3.2] Create Integration Tests
- Task 163: [P4.1] Register Hook in System
- Task 164: [P4.2] Configure Hook in Settings
- Task 165: [P5.1] Create Hook Documentation

## Execution Strategy

### Critical Path
1. **Foundation** (Sequential): Task 154 → Task 155
2. **Core Implementation** (Mixed):
   - Parallel: Tasks 156, 157
   - Then: Task 158
   - Parallel: Tasks 159, 160
3. **Testing** (Parallel): Tasks 161, 162
4. **Integration** (Parallel): Tasks 163, 164
5. **Documentation**: Task 165

### Parallel Execution Opportunities
- Phase 2: Tasks 156 & 157 can run in parallel
- Phase 2: Tasks 159 & 160 can run in parallel
- Phase 3: Tasks 161 & 162 can run in parallel
- Phase 4: Tasks 163 & 164 can run in parallel

### Estimated Complexity
- **Small tasks**: 4 (Foundation & Integration)
- **Medium tasks**: 6 (Core implementation & Documentation)
- **Large tasks**: 2 (Testing)

## Key Features Preserved

All tasks contain COMPLETE implementation details including:
- ✅ Full TypeScript code implementations
- ✅ Complete regex patterns for all placeholder types
- ✅ Detailed error message formatting
- ✅ Comprehensive test cases with purpose documentation
- ✅ Configuration examples with JSON
- ✅ Step-by-step integration instructions

## Risk Assessment

### Low Risk
- Foundation tasks (well-defined structure)
- Integration tasks (clear registry pattern)
- Documentation (standard format)

### Medium Risk
- Pattern matching (may need tuning)
- Error formatting (user experience critical)

### High Risk
- Violation detection logic (threshold tuning critical)
- False positive prevention (requires real-world testing)

## Next Steps

To implement the hook:
1. Run `stm list --status pending` to see all tasks
2. Start with Phase 1 tasks (154, 155) to establish foundation
3. Implement Phase 2 core logic (156-160)
4. Add comprehensive tests (161, 162)
5. Integrate into system (163, 164)
6. Document the feature (165)

### Verification Commands
```bash
# View all tasks
stm list --status pending

# View specific task details
stm show 154  # Shows first task with full implementation

# Update task status as you work
stm update 154 --status in_progress
stm update 154 --status completed

# Track progress
stm list --status completed | wc -l  # Count completed tasks
```

## Quality Validation

Each STM task includes:
- **Description**: Brief summary of what needs to be done
- **Details**: COMPLETE code implementations and technical requirements
- **Validation**: Specific acceptance criteria and test scenarios
- **Dependencies**: Clear task ordering
- **Tags**: Phase, priority, and size categorization

The decomposition successfully preserves all implementation details from the specification, ensuring tasks are self-contained and can be implemented without referring back to the original spec.
