Sdk

Gives Claude encrypted SQLite memory with vector search, Ed25519 signing, and payment rails for agent-to-agent transactions. Memory operations use either fast hash embeddings or optional semantic embeddings via Xenova transformers, with recall powered by sqlite-vec. Exposes deterministic key derivation from agent IDs, HMAC integrity checks on stored memories, and a credit scoring system (FICO 300-850) tied to payment history. Reach for this when you need persistent context across sessions with cryptographic audit trails, or when prototyping multi-agent systems that transact. The LongMem eval shows hash embeddings hold 100% exact recall through 5,000 memories. Built on Node 20+ with stdio transport.
