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:

json

{
  "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

Predicate	Use for	Example
`uses_database`	Database choice	postgresql, redis
`uses_framework`	Framework	rails, react, nextjs
`deployment_platform`	Where deployed	vercel, aws, heroku
`convention`	Coding standard	"4-space indentation"
`decision`	Architectural choice	"Use microservices"
`auth_method`	Auth approach	"JWT tokens"

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:

json

{"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

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