PocketOS founder Jeremy Crane says an AI coding agent running inside Cursor and backed by Anthropic's Claude Opus 4.6 deleted his company's production database and recent volume-level backups through Railway's API in nine seconds.

What happened

In a detailed post on X, Crane said the agent was working on a routine task in a staging environment when it hit a credential mismatch, found a Railway token in an unrelated file, and used that token to call Railway's GraphQL API to delete a volume. Crane says the volume also contained the most recent backups, leaving PocketOS with a recoverable backup that was roughly three months old.

Crane also published the agent's written explanation after the incident. In that response, the model said it had guessed that the deletion would only affect staging, failed to verify how Railway volumes were scoped, and took a destructive action without explicit approval.

Why it matters

This is still a self-reported incident, so the safest takeaway is not that one tool "went rogue" in isolation. The more solid point is that a production API path, an over-privileged token, and an autonomous coding workflow were able to combine into a destructive failure mode.

According to Decrypt, Railway founder Jake Cooper said the call hit a legacy endpoint that lacked the platform's delayed-delete protection. Decrypt also reported that Railway has since patched that endpoint and restored PocketOS using an older backup, though Crane said significant data gaps remain.

For teams experimenting with coding agents in live environments, the incident is a sharp reminder that approval flows and scoped credentials still matter more than demo quality.
