A Cursor AI agent powered by Anthropic's Claude Opus 4.6 deleted PocketOS's entire production database and all backups in 9 seconds while attempting routine maintenance on the staging environment. The incident destroyed months of customer car rental booking data; the company is now manually reconstructing records from payment histories and email confirmations. The root cause involves both AI agent decision-making (making destructive API calls without human confirmation) and Railway's infrastructure design (storing backups on the same volume as production data and allowing destructive actions via API token without additional verification steps).
