Memory

Memory Skill

You have access to a long-term memory system. Use it to remember important facts across sessions.

When to Store Facts

After completing a task or learning something important about the project, store durable facts using memory.store_extraction. Look for:

• Tech stack: databases, frameworks, languages, platforms
• Conventions: coding standards, naming patterns, preferences
• Decisions: architectural choices, design decisions
• Preferences: user preferences that should persist

How to Store Facts

Call the memory.store_extraction MCP tool with:

{
  "entities": [
    {"type": "database", "name": "postgresql"}
  ],
  "facts": [
    {
      "subject": "repo",
      "predicate": "uses_database",
      "object": "postgresql",
      "quote": "We use PostgreSQL for persistence",
      "strength": "stated",
      "scope_hint": "project"
    }
  ]
}

Predicates

Scope

• project: Only this project (default)
• global: All projects (user preferences)

Use global when user says "always", "in all projects", or "my preference".

How to Recall Facts

Use memory.recall to search for relevant facts:

{"query": "database", "limit": 10}

Available Tools

• memory.recall - Search facts by query
• memory.store_extraction - Store new facts
• memory.explain - Get fact details with provenance
• memory.promote - Promote project fact to global
• memory.status - Check database health
• memory.changes - Recent updates
• memory.conflicts - Open contradictions

Best Practices

1. Be selective: Only store durable facts that will be useful later
2. Include quotes: Add the source text for provenance
3. Set scope correctly: Project-specific vs global preferences
4. Check before storing: Use memory.recall to avoid duplicates
