No it doesn't? I've written commit messages ending with 'Co-authored-by [Claude]' a few times, in acknowledgement that it was largely 'vibed' and I only reviewed and committed it. I've never had Claude Code run `git commit`.
the models now commit because they think it is what we want, they are "relentlessly proactive" as simonw puts it, I now have to have instructions so they do not commit and push
