Users sometimes ask AI coding assistants to 'clean up', 'reset', 'start fresh', 'remove old files', or 'reorganize the project'. These requests are ambiguous — the user might mean 'move unused files' or they might mean 'permanently delete everything I don't currently need.' Deletion is irreversible (unless there's a backup or git history). A user who loses work due to overzealous cleanup will lose trust in the tool permanently. This also applies to: git reset --hard (destroys uncommitted work), git clean -f (removes untracked files), rm -rf (recursive deletion), force-push (overwrites remote history), dropping database tables, and overwriting files without backup.
