- The command Cursor actually ran also deleted the source code, the Git repo, the publish folder, and six months of backups.
- The source is a DEV Community post by the affected developer; no vendor response is included in the provided sources.

Who’s affected
- Cursor users who approve agent-run shell commands
What to do
- Keep backups on storage separate from the working drive so a single deletion cannot remove both
