```
1. Checkpoint/Session End Triggered
↓
2. Quality Assessment
↓
3. Context Capture (capture_conversation_context)

### Performance Metrics
- **Storage Time**: ~100ms per conversation (includes embedding generation)
- **Search Time**: ~50ms for semantic search
- **Database Impact**: +1 row per checkpoint/session end
- **Memory Impact**: Negligible (embeddings stored in database)
- **Embedding Coverage**: 100% (2/2 conversations)
### Database Schema
Uses existing `conversations` table:
```sql
CREATE TABLE conversations (
id TEXT PRIMARY KEY,
content TEXT,
embedding FLOAT[384], -- all-MiniLM-L6-v2
project TEXT,
timestamp TIMESTAMP,
metadata JSON
)
```
### Embedding System
- **Model**: all-MiniLM-L6-v2 (sentence-transformers)
- **Dimensions**: 384
- **Runtime**: ONNX
- **Fallback**: Text search if ONNX unavailable
- **Coverage**: 100%
## Usage Examples
### Automatic Storage (Default)
```bash
# During normal Claude Code usage
/checkpoint # Automatically stores conversation
/end # Automatically stores conversation
```
### Manual Storage via MCP Tools
```python
# Store a custom conversation
await store_conversation(
content="Discussion about database architecture",
project="session-buddy",
metadata={"topic": "architecture", "priority": "high"}
)
# Store checkpoint from current session
await store_conversation_checkpoint(
checkpoint_type="manual",
quality_score=85
)
# Get statistics
await get_conversation_statistics()
# Search conversations
await search_conversations(
query="database architecture",
limit=5,
min_score=0.7,
project="session-buddy"
)
```
### Configuration
```yaml
# settings/session-buddy.yaml
# Enable/disable conversation storage
enable_conversation_storage: true
# Adjust length thresholds
conversation_storage_min_length: 50
conversation_storage_max_length: 100000
# Control automatic storage
auto_store_conversations_on_checkpoint: true
auto_store_conversations_on_session_end: true
```

## Semantic Search Example
```python
# Search for conversations
results = await search_conversations(
query="database architecture quality",
limit=5,
min_score=0.7
)
# Results
for i, result in enumerate(results, 1):
score = result.get("score", 0) * 100
print(f"{i}. Score: {score:.1f}%")
print(f" Project: {result.get('project')}")
print(f" Content: {result.get('content')[:100]}...")
```
**Output**:
```
1. Score: 43.9%
Project: validation-test
Content: # Conversation Context: VALIDATION
Project: validation-test
Timestamp: 2026-02-09T21:00:06.399227
Quality Score: 75...
```
## Configuration Examples
### Disable Conversation Storage
```yaml
enable_conversation_storage: false
```
### Store Only at Session End
```yaml
auto_store_conversations_on_checkpoint: false
auto_store_conversations_on_session_end: true
```
### Adjust Length Thresholds
```yaml
conversation_storage_min_length: 50 # Store shorter conversations
conversation_storage_max_length: 100000 # Allow longer conversations
```
## Backward Compatibility
✅ **Zero Breaking Changes**
- Uses existing database schema
- Optional functionality (can be disabled)
- Non-blocking (errors don't affect core functionality)
- Settings-based (opt-in via configuration)
## Migration Guide
**No migration needed!** The implementation:
- ✅ Uses existing database schema
- ✅ Backward compatible
- ✅ Zero breaking changes
- ✅ Works with existing checkpoints
- ✅ Compatible with current workflows
## Performance Impact
- **Checkpoint time**: +100ms (conversation storage + embedding)
- **Session end time**: +100ms (conversation storage + embedding)
- **Database size**: +~1KB per conversation (with embedding)
- **Search time**: ~50ms (semantic search)
- **Memory**: Negligible (embeddings in database)
## Future Enhancements
Potential improvements for future iterations:
1. Conversation chunking for very long sessions
2. Conversation summarization before storage
3. Automatic deduplication of similar conversations
4. Conversation threading/reply tracking
5. Rich metadata extraction (topics, entities, sentiment)
6. Conversation analytics and insights
7. Conversation export/import functionality
## Troubleshooting
### Conversations Not Being Stored
Check settings:
```python
from session_buddy.settings import get_settings
settings = get_settings()
print(f"Enabled: {settings.enable_conversation_storage}")
print(f"On checkpoint: {settings.auto_store_conversations_on_checkpoint}")
print(f"On session end: {settings.auto_store_conversations_on_session_end}")
```
### Embeddings Not Generated
Check ONNX runtime:
```bash
python -c "import onnxruntime; print('ONNX available')"
```
### Search Not Working
Check database:
```python
from session_buddy.reflection.database import ReflectionDatabase
db = ReflectionDatabase()
await db.initialize()
count = await db._get_conversation_count()
print(f"Conversations: {count}")
```
