Hi @rkauf
Actually I know nothing about that passibility - I think you can’t use langgraph.json for now to modify the limit, can you? 
And honestly, why would that be useful if you can still use the context to modify it?
Remember that you can still set the default value vie .env or environment variables in your deployment platform: DEFAULT_RECURSION_LIMIT = int(getenv("LANGGRAPH_DEFAULT_RECURSION_LIMIT", "25")) → langgraph/libs/langgraph/langgraph/_internal/_config.py at main · langchain-ai/langgraph · GitHub
