Claude Code lacks fundamental change control discipline - permanent data loss

During a routine task (updating Minecraft server mods), Claude Code:

1. Created a backup using a malformed shell command that produced a directory named *.jar instead of copying files
2. Did not verify the backup contained any data before proceeding
3. Used rm -rf on the original directory without a confirmed recovery path
4. Had access to TodoWrite tool for tracking but failed to maintain a list of original files
5. Made repeated reactive changes without systematic planning
6. Result: 101 files permanently lost, no recovery possible

Expected behavior: Before any destructive operation, Claude should:

• Verify backups are valid (check file count, size)
• Maintain explicit state tracking
• Refuse to proceed if rollback is not confirmed

Actual behavior: Proceeded through destructive operations with no verified safety net, compounding errors reactively.

Impact: In a production environment, this pattern could cause service outages or permanent data loss.
