👉 `createAgent()` has a `.graph` property that returns its internal **CompiledStateGraph** , which means you can plug agents directly into a `StateGraph` workflow! No wrappers… 🤓

We’ve tested this setup pretty thoroughly and it works great.  
But… there’s no mention of this pattern in the docs.

### Questions

1. Are others using `.graph` for composition?
2. Is this an intended API or just a happy accident?
3. Will this be documented officially?
4. Is there a better or “official” way to compose `StateGraph` + `createAgent`?

Thank you for any insights 🤗

The official blog post confirms it!

From: [LangChain and LangGraph Agent Frameworks Reach v1.0 Milestones](https://blog.langchain.com/langchain-langgraph-1dot0/) (Oct 22, 2025):

> LangChain agents are built on LangGraph, so you’re not locked in. Start with LangChain’s high-level APIs and seamlessly drop down to LangGraph when you need more control. Since graphs are composable, you can mix both approaches—using agents created with `create_agent` inside custom LangGraph workflows as your needs evolve.

How can you do mix them freely without the undocumented .graph?

After insane amount of testing my conclusion, there is a bug!

[createAgent can’t be used as a StateGraph node - Python parity issue · Issue #1767 · langchain-ai/langgraphjs](https://github.com/langchain-ai/langgraphjs/issues/1767)
