## Overview

This repository contains no application source in the supplied tree. Its README describes Letta as a platform for stateful agents and directs active development to the separate letta-code project. The diagram therefore captures only documented ways to use the product; it does not infer internal runtime components or wiring.

Main entry points: [`README.md`](https://github.com/cpacker/memgpt/blob/main/README.md) (Product overview)
