This is a comprehensive reference for building on the Letta API, which gives you stateful agents with persistent memory and long-term learning. You get 24 working examples across Python and TypeScript covering the core patterns: setting up clients, managing memory blocks (core, archival, and conversation history), building custom tools, and handling multi-user scenarios. The examples include both server-side tools that run in Letta's sandbox and client-side tools that execute locally on your machine (the pattern Letta Code uses). It covers the tricky bits like tool rules for constraining execution order, shared memory blocks for multi-agent coordination, and streaming with pings to avoid timeouts. If you're building chatbots or assistants that need to remember context across sessions or learn over time, this gives you the SDK patterns to do it right.
