Hey guys I m using the `create llama

ngl there isn't an easy way to do this haha

You can't add a system prompt to the agent itself (as far as I know), since langchain doesn't really expose that

But you can adjust the prefix of the agent

create_llama_chat_agent(..., agent_kwargs={"PREFIX": "My Prefix"})

Here's the default prefix
