You can roll back commits

Not when it deletes .git. Or your home directory.

Never had that happen but you should always push your commits.

It has happened. https://news.ycombinator.com/item?id=46268222

Not for changes made outside of the repo….

I havent ever seen Claude do that so thats news to me, always asks for permission to go anywhere else.

Sure, it tries really hard not to, but there might be some attack/malware/hidden prompt that does it, one day, out of the blue...
