Add long-term memory with Letta
Wire a hierarchical memory store into an existing agent and audit what it remembers.
Prereqs
- Existing agent
- Postgres or Letta cloud
Long-term memory is where agent quality silently drifts. This guide adds explicit memory and an audit affordance.
Step 1: Decide what to remember
Not every interaction belongs in memory. Define the criteria up front.
Step 2: Wire Letta
Drop in the Letta SDK. Expose explicit recall and edit tools to the agent.
Step 3: Add a “what do you remember about me?” affordance
Users should be able to inspect and delete memory. This is increasingly a regulatory requirement, not just a courtesy.
