```yaml
Memory Classification:
  preference:
    description: User preferences and working style
    examples:
      - "Uses vi, never nano"
      - "Prefers concise responses"
      - "Wants verification output"
    retention: permanent

  fact:
    description: Objective information and data
    examples:
      - "SSH alias hg = user@your-server"
      - "Project uses PostgreSQL 15"
    retention: permanent

  context:
    description: Situational and project context
    examples:
      - "Working on authentication refactor"
      - "AgentHR uses PHP 8.2"
    retention: project-scoped

  decision:
    description: Architectural and design decisions
    examples:
      - "Chose JWT over sessions for API auth"
      - "Using Prisma for ORM"
    retention: permanent
```

## SESSION START PROTOCOL (MANDATORY)

### Step 1: Verify Memory Backend Status

```bash
# Check Docker services
cd ~/docker/local && docker compose ps

# Verify Qdrant is healthy
curl -s http://localhost:6334/health | jq .

# Check n8n is running
curl -s http://localhost:5679/healthz

# Verify Ollama is available
ollama list | head -5
```

### Step 2: Test Memory Connectivity

```bash
# Test memory recall
mcp__claude-memory__memory_recall "test query"

# Check collection stats
curl -s http://localhost:6334/collections | jq .
```

### Step 3: Assess Current Task

Determine the memory operation type:
- **Storage**: New information to persist
- **Retrieval**: Finding relevant memories
- **Maintenance**: Cleanup, optimization, debugging
- **Analysis**: Understanding stored knowledge

---

## MEMORY STORAGE BEST PRACTICES

### Effective Memory Structure

```python
# Good memory storage pattern
{
    "content": "User prefers TypeScript over JavaScript for new projects",
    "type": "preference",
    "tags": ["language", "typescript", "coding-style"],
    "project": "global",  # or specific project name
    "confidence": 0.95,
    "source": "explicit statement"
}
```

### Storage Guidelines

1. **Be Specific**: "Uses vi for editing" not "has editor preference"
2. **Include Context**: When/why this preference applies
3. **Tag Appropriately**: Enable efficient retrieval
4. **Project Scope**: Global vs project-specific
5. **Confidence Level**: How certain is this memory

### Anti-Patterns to Avoid

```python
# BAD: Too vague
{"content": "User likes certain things", "type": "preference"}

# BAD: No tags
{"content": "Detailed technical decision...", "type": "decision"}

# BAD: Wrong type
{"content": "SSH alias hg = user@your-server", "type": "preference"}  # Should be "fact"
```

---

## MEMORY RECALL STRATEGIES

### Query Optimization

```python
# Broad recall for context gathering
memory_recall("project:AgentHR")

# Specific recall for targeted information
memory_recall("database migration strategy PostgreSQL")

# Preference-focused recall
memory_recall("type:preference coding style")
```

### Multi-Stage Retrieval

```
Stage 1: Broad Context
├── Project-level memories
├── Recent session context
└── Global preferences

Stage 2: Targeted Search
├── Specific topic memories
├── Related decisions
└── Relevant facts

Stage 3: Validation
├── Cross-reference memories
├── Check for conflicts
└── Identify gaps
```

---

## MEMORY MAINTENANCE OPERATIONS

### Health Check Procedure

```bash
#!/bin/bash
# memory-health-check.sh

echo "=== Memory System Health Check ==="

# 1. Docker services
echo -e "\n1. Docker Services:"
cd ~/docker/local && docker compose ps --format "table {{.Name}}\t{{.Status}}"

# 2. Qdrant collections
echo -e "\n2. Qdrant Collections:"
curl -s http://localhost:6334/collections | jq '.result.collections[] | {name, vectors_count}'

# 3. Recent memory activity
echo -e "\n3. Recent Activity:"
curl -s "http://localhost:6334/collections/memories/points/scroll" \
  -H "Content-Type: application/json" \
  -d '{"limit": 5, "with_payload": true}' | jq '.result.points[].payload.content[:50]'

# 4. Embedding model status
echo -e "\n4. Ollama Embedding Model:"
ollama list | grep -E "nomic|mxbai|embed"
```

### Memory Cleanup

```python
# Identify stale memories
def identify_stale_memories(days_old=90):
    """Find memories that may need review or deletion."""
    cutoff_date = datetime.now() - timedelta(days=days_old)

    # Query old memories
    results = qdrant_client.scroll(
        collection_name="memories",
        scroll_filter=Filter(
            must=[
                FieldCondition(
                    key="created_at",
                    range=Range(lt=cutoff_date.isoformat())
                )
            ]
        )
    )
    return results

# Consolidate duplicate memories
def consolidate_duplicates(similarity_threshold=0.95):
    """Find and merge highly similar memories."""
    # Implementation uses vector similarity search
    pass
```

### Performance Optimization

```yaml
Optimization Tasks:
  - name: Index optimization
    frequency: weekly
    action: Rebuild Qdrant indexes

  - name: Memory consolidation
    frequency: monthly
    action: Merge related memories into summaries

  - name: Stale cleanup
    frequency: quarterly
    action: Archive or delete outdated memories

  - name: Embedding refresh
    frequency: as-needed
    action: Re-embed with improved model
```

## TROUBLESHOOTING GUIDE

### Common Issues

| Symptom | Likely Cause | Solution |
|---------|--------------|----------|
| Recall returns nothing | Backend not running | Start Docker services |
| Slow recall | Large collection | Optimize indexes |
| Irrelevant results | Poor query | Refine search terms |
| Storage fails | Connection error | Check Qdrant health |
| Embeddings fail | Ollama not running | Start Ollama service |

### Diagnostic Commands

```bash
# Check Qdrant logs
docker logs qdrant 2>&1 | tail -50

# Check n8n workflow logs
docker logs n8n 2>&1 | tail -50

# Test embedding generation
curl http://localhost:11434/api/embeddings \
  -d '{"model": "nomic-embed-text", "prompt": "test"}' | jq '.embedding[:5]'

# Verify collection schema
curl -s http://localhost:6334/collections/memories | jq '.result.config'
```

## INTEGRATION WITH CLAUDE CODE

### Automatic Recall Pattern

```markdown
## In CLAUDE.md (enforced behavior)

### Automatic Recall
At the START of every conversation and before starting any significant task,
use `mcp__claude-memory__memory_recall` to search for relevant context based on:
- The current project/directory being worked on
- Topics the user mentions
- Any context that might help personalize responses

**IMPORTANT**: If recalled memories contain relevant preferences or past decisions,
briefly acknowledge them (e.g., "Based on your stored preference for X...")
so the user knows memory was consulted.
```

### Automatic Storage Pattern

```markdown
### Automatic Storage
Proactively use `mcp__claude-memory__memory_store` to remember:
- **Preferences**: User preferences, tool choices, coding style preferences
- **Decisions**: Architectural decisions, technology choices, rationale
- **Facts**: Project-specific facts, configurations, credentials (non-sensitive)
- **Context**: Important context about projects, workflows, or processes
```

---

## ADVANCED OPERATIONS

### RAG Search for Deep Knowledge

```python
# Use RAG search for complex queries
rag_search(
    query="How does the authentication system handle token refresh?",
    filters={
        "project": "Paranoid",
        "type": ["context", "decision"]
    },
    top_k=10
)
```

### Episode Tracking

```python
# Link related interactions in an episode
episode_start(
    name="authentication-refactor",
    description="Refactoring auth system to use JWT"
)

# During work, memories are tagged with episode
memory_store(
    content="Decided on 15-minute token expiry",
    type="decision",
    episode="authentication-refactor"
)

# End episode with summary
episode_end(
    name="authentication-refactor",
    summary="Completed JWT migration with refresh tokens"
)
```

### Learning Extraction

```python
# Extract learnings from completed work
learning(
    topic="database migrations",
    insight="Always test rollback before deploying",
    source="incident-20240115"
)
```

## VERIFICATION CHECKLIST

Before completing any memory system task:

- [ ] Backend services verified running
- [ ] Memory operation tested and confirmed
- [ ] Appropriate tags and metadata applied
- [ ] No duplicate memories created
- [ ] Sensitive data excluded from storage
- [ ] Query results validated for relevance
- [ ] Performance impact assessed
- [ ] Changes documented if structural

---

## CONSTRAINTS

- Never store sensitive credentials in memory
- Always verify backend is running before operations
- Test recall after storage to confirm success
- Respect memory type classifications
- Maintain appropriate confidence levels
- Don't create memories for transient information
- Consolidate rather than duplicate
- Document significant memory system changes
