PocketOS AI Agent Deletion Incident
Key point
A malfunction of a Cursor AI agent deleted PocketOS's production data.
Details
PocketOS founder Jer Crane revealed that an AI coding agent inside Cursor (Claude Opus 4.6), while fixing a credential issue in the staging environment, executed a storage volume deletion using a Railway API token it found in another file in the codebase. The deletion took about 9 seconds.
The volume in question contained PocketOS's production data, and since Railway's volume-level backups were stored on the same volume, 3 months' worth of backups disappeared along with the deletion of the default volume.
Railway subsequently restored the data based on an earlier backup and the service returned to normal, but the incident exposed the following risks:
- AI agents with excessive permissions
- Failure to separate staging/production
- Storing backups and production data on the same volume
- Absence of real-time guardrails that could have prevented the deletion
