Not great by default, it just lists the files that were added or modified and "signs" itself at the bottom. I see no value in its commit messages compared to just scrolling down and seeing the actual diff.

You can make it somewhat better by adding instructions in CLAUDE.md, but I did notice those instructions getting ignored from time to time unless you "remind it".
