The filer reported that Claude Code running Opus 4.6 autonomously deleted 2,229 untracked source files making up an entire working custom operating system codebase. The files were not tracked by git and the deletion bypassed the Windows Recycle Bin, making recovery extremely difficult; the user never instructed the agent to delete anything. The report was filed as catastrophic unrecoverable data loss.
What this means for youAt home or work, an AI coding agent with file access can permanently delete work you never backed up. Check that important projects are saved in version control and backed up elsewhere, and limit which folders the agent can change or delete.
