Bug Description
In the last two days, Claude Code is consistently making unauthorized changes to files where no prompt or direction was given to touch them. [Image #5] This is just one example, and it's becoming a pattern now and extremely concerning and breaking trust. I will submit more screenshots with feedback as I continue seeing this happen.

I closed this issue because it is similar to issue #40401, which is much better written than mine.

How do you thumb up another issue, an existing issue? I don't see any place
to do that in GitHub issues.
