longterm memory

This hands-on guide demystifies AI agent memory for Bash-friendly Linux users and shows how to add durable, auditable long-term recall to terminal assistants using SQLite, sentence-transformer embeddings, and thin Bash wrappers; it explains memory layers (short-term, working, episodic/semantic), RAG-based retrieval, namespaces, pruning, and guardrails, with install steps and real-world ops examples to cut cost, latency, and re-asks.
