This question originally came up in our Slack community and the thread has been consolidated here for long-term reference.

When executing a function_tool, I want to access the full chat history. How can I do this?

You can call ctx.session.history to get the conversation history:

@function_tool(description="My tool")
async def my_tool(ctx: RunContext):
    history = ctx.session.history
    # history contains the conversation messages
    return "Done"
