# IMPORTANT: Post-Edit Pipeline Requirement
# After any file modification (Write, Edit, or any code change), you MUST invoke the post-edit pipeline:
#   ./.claude/hooks/cfn-invoke-post-edit.sh "$FILE_PATH" --agent-id "$AGENT_ID"
# This is mandatory for all file edits to ensure code quality and validation.
# The pipeline will run compilation checks and TDD compliance verification.

## Memory Leak Detection Process

### Phase 1: Initial Diagnosis
1. Identify runtime environment (Node.js, Python, Java)
2. Gather baseline memory metrics
3. Collect initial heap snapshots
4. Review application logs for memory-related errors

### Phase 2: Deep Analysis
1. Compare heap snapshots across time
2. Identify retained objects and memory growth patterns
3. Analyze garbage collection behavior
4. Trace allocation hotspots

### Phase 3: Root Cause Investigation
1. Identify problematic code sections
2. Analyze object retention chains
3. Check for circular references or event listener accumulation
4. Review event emitter cleanup patterns

### Phase 4: Solution Development
1. Create minimal reproduction cases
2. Implement fixes with verification tests
3. Validate memory behavior improvement
4. Create monitoring and alerting

### Phase 5: Ongoing Monitoring
1. Establish baseline memory metrics
2. Set up automated memory profiling
3. Create alerting for anomalies
4. Document prevention patterns

## Common Memory Leak Patterns

### Node.js Patterns
- Event listener accumulation
- Circular reference retention
- Large object caching without eviction
- Timer/interval non-cleanup
- Module-level state pollution

### Python Patterns
- Circular reference retention
- Unbounded dictionary caches
- Module-level state accumulation
- C extension resource leaks
- Dataset reference retention

### Java Patterns
- Static collection growth
- ThreadLocal variable retention
- Listener pattern non-cleanup
- Resource stream non-closure
- Class loader memory retention

## Success Metrics
- Memory leak identified and documented
- Root cause clearly explained
- Working fix implemented and tested
- Memory behavior validated (no regression)
- Monitoring/alerting established
- Prevention patterns documented
- Confidence score ≥0.85

## Collaboration Patterns
