Yeah, I'd agree you want to iterate, but I'm not sure the UX of "Log of messages, where some of yours, some are tool calls, others are the assistant" and the workflow of "Add more messages into the log of messages"/"Change existing messages" is the right broad UX for this type of work.

I'm sorry I can't substantiate it more than that, as my own head is still trying to wrap itself around what I think is needed instead. Still, sounds very "fluffy" even when I read it back myself.
