If you've worked from a plan, it's trivial. I've got a setup where the agent reads the implementation plan, then creates a commit history based on intent rather than location.
Exactly. "Why was this change made"? "What were the options"? "Why this is a good way of doing it"? "What are the subtle things I came across while making this change"?
There isn't one. Most of time you would pair review a PR with human who wrote it and they could explain that. They can't anymore since 9/10, they didn't think through those things.
