It is not clear to me that keeping prompts/conversations at something like this level of granularity is a _bad_ idea, nor that it's a good one. My initial response is that, while it seems cute, I can't really imagine myself reading it in most cases. Perhaps though you'd end up using it exactly when you're struggling to understand some code, the blame is unclear, the commit message is garbage, and no one remembers which ticket spawned it.

You could also feed it back to the next AI agent.
