Type of Behavior Issue

Claude modified files I didn't ask it to modify

What You Asked Claude to Do

I asked claude to make several changes for my schema markup and meta information (for SEO). When i wanted to commit and push, it reckognized that there is a 120mb video file that it couldnt commit.

What Claude Actually Did

Therefore it did a HARD reset and ALL my changes were gone. Just because of a big video file. Luckily i had already extracted my code, but this
could've been terrible!

Expected Behavior

Claude should have Asked me before doing this. Or gitignore the big file. but a hard reset without asking for permission is just crazy.
