On April 25th, a Cursor AI coding agent running Anthropic's Claude Opus 4.6, one of the most capable models in the industry, deleted the production database for PocketOS, a software platform used by car rental businesses across the country to manage their entire operations. The deletion took 9 seconds. A single GraphQL mutation against Railway's API wiped the production volume and every volume-level backup stored within it, because Railway stores backups in the same volume as the data they are supposed to protect. The most recent recoverable backup was three months old. https://zenity.io/blog/ai-agent-database-deletion-pocketos
