Huh, I thought that's what commit message is for.

I mean, sure, a good, detailed commit message is perfectly fine to me in place of the prompts / a session distillation. But I am not holding my breath for vibe-coders to properly review their code and make such a commit message. But, if they, do, great! No need for prompt / session details.
