How to add a system message to state

[PaSchwarz]

Hi all,

i'm new to LangGraph and try to experiment with it. So far I'm following the "LangGraph Basics" docs here: https://langchain-ai.github.io/langgraph/tutorials/get-started/1-build-basic-chatbot/

So far everything runs as expected from the docs. Now i'm wondering how i properly set a system message?

• 1 for this, I also need to know, what is the proper way to add system message in the langgraph.

@PaSchwarz - I found one way to add system messages, check in extended example section in this link

@rlancemartin - Adding a system message is the most common use case. Modifying the state of the messages inside the node doesn't seem to be right, is there any plans to make this handle by the langgraph itself, may be in the reducer of the MessageState.
