Agent Memory Persistence

Use this skill when an agent needs durable memory storage across sessions.

What it provides

• SQLite-backed persistence for text, metadata, and embedding vectors
• CRUD operations for memory items
• Semantic retrieval with cosine-similarity vector search
• Memory lifecycle operations including expiration cleanup
• Filters by user, session, type, and time window

Project structure

• src/MemoryStore.ts: low-level SQLite storage engine
• src/VectorIndex.ts: vector similarity search over stored embeddings
• src/MemoryManager.ts: high-level API used by agents
• src/types.ts: shared TypeScript contracts
