Summary
If you're building agents with Letta, this is the architecture guide you'll want nearby. It walks through choosing between letta_v1_agent and memgpt_v2_agent, structuring memory blocks, picking models, and configuring tools. The skill covers shared memory setups and debugging memory issues, which matters since Letta's whole thing is stateful agents with long-term memory. It's comprehensive enough to guide a project from scratch but focused enough to be useful when you're stuck on a specific decision. With 143 installs and passing most security audits, it's clearly being used in real projects. Worth having if you're doing anything serious with Letta agents.
