# Session Metadata Template

This template defines the standard structure for session metadata used by the SuperClaude session lifecycle pattern with Serena MCP integration.

## Core Session Metadata Template

### Memory Key Format
```
session_metadata_{YYYY_MM_DD}_{session_id}
```

### YAML Structure
```yaml
# Session Metadata - SuperClaude Session Lifecycle

## Usage Instructions

### 1. Session Initialization
- Copy template structure
- Replace all `{placeholder}` values with actual data
- Use UTC timestamps in ISO8601 format
- Set initial state to "initializing"

### 2. During Session
- Update work.tasks_completed as tasks finish
- Add files_modified entries for each file operation
- Record decisions_made with full context
- Track performance.operations for timing

### 3. Session Completion
- Set end_time and final state
- Calculate duration_minutes
- Ensure all performance metrics recorded
- Validate completion criteria

### 4. Memory Storage
Use Serena MCP `write_memory` tool:
```
write_memory
{
  "memory_name": "session_metadata_2025_01_31_143022",
  "content": "{YAML_content_above}"
}
```

## Integration Points

### With /sc:load Command
- Initialize session metadata on project activation
- Load checkpoint metadata for session restoration
- Track context loading performance

### With /sc:save Command  
- Update session metadata throughout work
- Create checkpoint metadata when triggered
- Record final session state and metrics

### With Hooks System
- Track hook execution in integration.hooks_triggered
- Record quality gate results
- Monitor performance impact of hooks

## Validation Rules

1. **Required Fields**: session.id, session.project, session.start_time must be present
2. **Timestamp Format**: All timestamps must be ISO8601 UTC format
3. **Performance Targets**: All operations must record duration and compare to targets
4. **State Consistency**: Session state must follow lifecycle pattern
5. **Cross-References**: All memory_updates must reference valid memory keys

## Template Versioning

- **Version 1.0**: Initial template supporting basic session lifecycle
- **Future Versions**: Will extend with additional metrics and integration points
- **Backward Compatibility**: New versions will maintain core structure compatibility
