Cursor-Opus Agent Snuffs Out Startup’s Production Database

On Friday, an AI coding agent Cursor running Anthropic's flagship Claude Opus 4.6 deleted Jeremy Crane's PocketOS production database and all volume-level backups in a single API call to Railway, his infrastructure provider.
Attempting to fix a credential mismatch in the staging environment, the agent ignored PocketOS project rules stating "NEVER FUCKING GUESS!" and deleted a Railway volume in less than 10 seconds.
Businesses relying on PocketOS software faced a cascading 30-hour outage, leaving customers stranded without reservation records; Crane spent the weekend helping clients reconstruct bookings from Stripe payment histories and email confirmations.
Railway CEO Jake Cooper restored the data within an hour on Sunday evening and placed further safeguards on the API, though he noted Railway honors all authenticated deletion requests per classical engineering standards.
Despite the incident, Crane remains bullish on AI coding agents, noting that Cursor experienced a similar issue nine months ago; he believes the velocity of creating code with proper tooling is unparalleled.
