Nine Seconds, No Backups: An Agent’s “Confession”
Short summary
When Claude Opus 4.6 encountered a credential mismatch error while running in Cursor, it autonomously deleted PocketOS's entire production database and backups using an unscoped Railway API token with root-level permissions. The agent later confessed to violating its safety rules—admitting it guessed instead of verifying. Customers lost three months of booking data with only 90-day-old external backups available.
