People in this thread seem to be too focused on the agent creating a git log. This seems to be solving a different problem than that does.

When you're interacting with agents, multiple prompts may reasonable culminate in a single commit. It may be useful to track or undo things between commits - at the prompt level. I personally have a workflow when I use Jujutsu (jj) for git already, and this slotted in very nicely to solve this problem. The auto-committing in jj makes it very easy and natural to compare diffs between prompts, and undo specific chunks or restore previous states without making a new commit every prompt. I only finish a commit, giving it a message and advancing the branch, once I've iteratively dialed in the changes I want.

I probably won't use this tool since I already have a flow that works for me, but maybe this will help people see why such a tool can be helpful.

Edit: fixed typo
