langchain-ai/memory-agent

This is a LangGraph ReAct memory agent: a user sends conversation messages, the graph retrieves user-scoped memories, asks a configured chat model to respond or request memory updates, and stores requested updates before continuing the graph. Memory is scoped by configurable user_id so it can be reused across threads. The graph, context, prompt, state, tool, and model-loader modules are represented; the store and model are runtime-provided dependencies. Relationships are based on the README and sampled source; the memory-review UI link is documented but its implementation is outside this repository.
