# Meta-Rule: Bug Fixing

**Author**: Matthew Raymer
**Date**: 2025-08-21
**Status**: 🎯 **ACTIVE** - Bug fix implementation workflow bundling

## Purpose

This meta-rule bundles all the rules needed for implementing bug fixes
with proper testing and validation. Use this after diagnosis when
implementing the actual fix.

## When to Use

- **Post-Diagnosis**: After root cause is identified and fix is planned
- **Fix Implementation**: When coding the actual bug fix
- **Testing & Validation**: When testing the fix works correctly
- **Code Review**: When reviewing the fix implementation
- **Deployment**: When preparing the fix for deployment
- **Documentation**: When documenting the fix and lessons learned

## Bundled Rules

### **Implementation Standards**

- **`development/software_development.mdc`** - Core development
  principles, evidence requirements, and testing strategy
- **`development/type_safety_guide.mdc`** - Type-safe implementation
  with proper error handling and type guards
- **`development/logging_migration.mdc`** - Proper logging
  implementation and migration from console.* calls

### **Code Quality & Review**

- **`development/historical_comment_management.mdc`** - Code quality
  standards and comment transformation rules
- **`development/historical_comment_patterns.mdc`** - Specific
  patterns for transforming historical comments
- **`development/complexity_assessment.mdc`** - Complexity evaluation
  for fix implementation

### **Platform & Testing**

- **`app/timesafari_development.mdc`** - TimeSafari-specific
  development workflow and testing requirements
- **`app/timesafari_platforms.mdc`** - Platform-specific testing
  and validation requirements
- **`architecture/build_validation.mdc`** - Build system validation
  and testing procedures

## Workflow Sequence

### **Phase 1: Fix Implementation (Start Here)**

1. **Development Standards** - Apply `software_development.mdc` for
   core implementation principles
2. **Type Safety** - Use `type_safety_guide.mdc` for type-safe
   implementation
3. **Logging Implementation** - Apply `logging_migration.mdc` for
   proper logging

### **Phase 2: Quality & Review**

1. **Code Quality** - Use `historical_comment_management.mdc` for
   code quality standards
2. **Complexity Assessment** - Apply `complexity_assessment.mdc` to
   evaluate fix complexity
3. **Code Review** - Follow review standards from bundled rules

### **Phase 3: Testing & Validation**

1. **Platform Testing** - Use `timesafari_platforms.mdc` for
   platform-specific testing
2. **Build Validation** - Apply `build_validation.mdc` for build
   system compliance
3. **Final Validation** - Verify fix works across all platforms

## Success Criteria

- [ ] **Fix implemented** following development standards
- [ ] **Type safety maintained** with proper error handling
- [ ] **Logging properly implemented** with component context
- [ ] **Code quality standards met** with clean, maintainable code
- [ ] **Testing completed** across all target platforms
- [ ] **Build validation passed** with no build system issues
- [ ] **Code review completed** with all feedback addressed
- [ ] **Documentation updated** with fix details and lessons learned

## Common Pitfalls

- **Don't skip type safety** - leads to runtime errors
- **Don't ignore logging** - makes future debugging harder
- **Don't skip platform testing** - misses platform-specific issues
- **Don't ignore code quality** - creates technical debt
- **Don't skip build validation** - can break build system
- **Don't forget documentation** - loses fix context for future

## Integration Points

### **With Other Meta-Rules**

- **Bug Diagnosis**: Investigation results drive fix implementation
- **Feature Implementation**: Fix patterns inform future development
- **Feature Planning**: Fix complexity informs future planning

### **With Development Workflow**

- Fix implementation follows development standards
- Testing strategy ensures fix quality
- Code review maintains code quality

## Feedback & Improvement

### **Sub-Rule Ratings (1-5 scale)**

- **Development Standards**: ___/5 - Comments: _______________
- **Type Safety**: ___/5 - Comments: _______________
- **Logging Migration**: ___/5 - Comments: _______________
- **Code Quality**: ___/5 - Comments: _______________
- **Platform Testing**: ___/5 - Comments: _______________

### **Workflow Feedback**

- **Implementation Clarity**: How clear was the implementation guidance?
- **Testing Coverage**: Were testing requirements sufficient or excessive?
- **Process Effectiveness**: How well did the workflow work for you?

### **Sub-Rule Improvements**

- **Clarity Issues**: Which rules were unclear or confusing?
- **Missing Examples**: What examples would make rules more useful?
- **Integration Problems**: Do any rules conflict or overlap?

### **Overall Experience**

- **Time Saved**: How much time did this meta-rule save you?
- **Quality Improvement**: Did following these rules improve your fix?
- **Recommendation**: Would you recommend this meta-rule to others?

## Model Implementation Checklist

### Before Bug Fixing

- [ ] **Root Cause Understood**: Confirm root cause is clearly identified
- [ ] **Fix Strategy Planned**: Plan implementation approach and testing
- [ ] **Platform Impact Assessed**: Understand impact across all platforms
- [ ] **Testing Strategy Planned**: Plan testing approach for the fix

### During Bug Fixing

- [ ] **Rule Application**: Apply bundled rules in recommended sequence
- [ ] **Implementation**: Implement fix following development standards
- [ ] **Testing**: Test fix across all target platforms
- [ ] **Documentation**: Document implementation details and decisions

### After Bug Fixing

- [ ] **Validation**: Verify fix meets all success criteria
- [ ] **Code Review**: Complete code review with team
- [ ] **Deployment**: Deploy fix following deployment procedures
- [ ] **Feedback Collection**: Collect feedback on meta-rule effectiveness
