What does deep-agents-memory do?
deep-agents-memory is a skill that shows how to give a LangChain Deep Agent files and memory, with Python and TypeScript code. It explains the backends: StateBackend keeps files for one thread, StoreBackend keeps them across threads, FilesystemBackend uses the real disk, and CompositeBackend routes paths such as /memories/ to a lasting store. FilesystemMiddleware adds ls, read_file, write_file, edit_file, glob and grep tools. It also lists common mistakes: StoreBackend without a store, InMemoryStore in production where PostgresStore belongs, a missing virtual_mode, and file paths that miss the route prefix.
When should you use deep-agents-memory?
Use it when
- Your Deep Agent forgets files when a new thread starts
- You want some paths saved for good and others temporary
- You want an agent to read and write local files safely
Skip it when
- You don't use LangChain Deep Agents
- Your agent only handles single conversations
What it needs and what it can touch
You need
- The deepagents library for Python or TypeScript
From reading its instructions, not from running it.
