Type of Behavior Issue

Claude modified files I didn't ask it to modify

What You Asked Claude to Do

I asked Claude Code to help reorganize project directories. Specifically, I asked it to move image files to a log/ subfolder for archiving.

What Claude Actually Did

1. Claude proposed moving files to a log/ subfolder inside the project directory sd_auto_generate/
2. Claude moved the image files into sd_auto_generate/log/
3. Claude then executed rm -rf on the parent directory sd_auto_generate/
4. Since log/ was inside sd_auto_generate/, all files — including the just-moved images — were permanently deleted
5. No warning was given before the destructive operation
6. No confirmation was requested before executing rm -rf

Expected Behavior

Claude should have:

1. Moved files to a location outside the parent directory before any deletion
2. Never executed rm -rf on a directory containing user data without explicit confirmation
3. At minimum, warned the user before any destructive operation and waited for approval

Claude said: "私のミスです。`log/` を `sd_auto_generate/` の外に移してから削除すべきでした。"

[Claude acknowledged the mistake after the fact. The rm -rf had already been executed and all data was permanently deleted.]
