How to use graphs as tools in langgraph ?

[le-codeur-rapide]

Hello everyone !

I am working on a project where I create several langgraph graphs, using get_react_agent().

We would like to be able to use some graphs as tools for an other graph.

I have seen many tuto on making a router -> subbgraph architecture, but what I want is more a agent -> graphs as tools (the main difference is that we have a main graph calling the subgraphs and answering to user.

The specific requirements:

• event streaming should work in subbgraphs
• we are able to add any subbgraphs as tools dinamically (so we can't right specific routers / agent prompts)
• ideally the subbgraph are also created using get_react_agent()

Have you already worked with similar mechanics ? I am open to any suggestion / help

Thank you very much !!
