I don't really understand why the comment has been downvoted.We actually need more of this, perhaps not in this exact shape, but similar.It would be extremely cool to be able to write one or two lines of prompt in my harness, and have a light model iterate with me a few times writing/proposing requirements, guidelines and explanations, refining the prompt until it's ready to be sent to the actual LLM.Lack of specifications in the prompt is (imho?) one of the main drivers that lead the LLMs astray, and it often happens because it's not realistic to always type or even thing every angle before submitting each prompt.Think of it as the missing link between a single-shot prompt and a skill.It should be ideally integrated in the chat, for quick access.This project is probably different in aim, but I still find it interesting.
