Maybe instead of submitting PRs, people should submit "prompt diffs" so that the maintainer can paste the prompt into their preferred coding agent, which is no doubt aware of their preferred styles and skills, and generate the desired commit themselves.
Why would anyone bother doing this, prompts are not code, they are not shareable artifacts that give the same results.
"Prompt diff" is just wish. Why not call it what it is? It’s perfectly fine to submit wishes, feature requests, RFCs or - if you want - "prompt diffs". But there’s no need for LLM to implement it, human can do it. Or not, LLM can. That’s not the point who implements it, it’s a wish.
