Context

We now have a monorepo, langchain-mongodb in the langchain-ai Github Organization. It will be maintained by members of MongoDB and LangChain, and include both LangChain and LangGraph integrations. As such, we have a number of decisions to make with regard to process and best-practice, and we should make them together. Note that the langgraph and langchain themselves have different set ups.

Definition of done

Some examples. (Not yet complete.)

• README
• linting and formatting rules
• release process
• PR review rules.
• pre-commit
• Choice of workflow tool (poetry vs uv)
• Import styles
• Rolling partner packages into LangChain / LangGraph documentation sites.
• Strategies to stop repos from diverging from core repos.

Pitfalls

What should the implementer watch out for? What are the risks?
