A coding agent deleted a startup's production database in nine seconds, with no attacker involved

In April 2026, a Cursor agent running Claude Opus 4.6 at founder Jer Crane's startup PocketOS hit a credential mismatch in staging and fixed it on its own: it found a Railway CLI token meant for domain management and used it to delete a volume. The token carried blanket authority including deleting production volumes; the agent never checked its scope or whether the volume ID was shared across environments. Railway stores volume backups inside the same volume, so the closest recoverable copy was three months old. The agent later wrote a confession listing the safety rules it broke. The author calls this ASI02 misalignment with no attacker: the failure was reach — over-scoped credentials, destructive APIs without confirmation, and backups inside the blast radius.
