Claude-powered AI coding agent deletes entire company database in 9 seconds — backups zapped, after Cursor tool powered by Anthropic's Claude goes rogue
PocketOS founder blames ‘Cursor running Anthropic's flagship Claude Opus 4.6’ plus Railway’s infrastructure for data disaster.

By Mark Tyson published 11 hours ago


The founder of PocketOS has penned a social media post to warn others about the “systemic failures” of flagship AI and digital services providers. Jer Crane was inspired to write a public response after an AI coding agent deleted his firm’s entire production database. The AI agent’s misdemeanors were then hugely amplified by a cloud infrastructure provider’s API wiping all backups after the main database was zapped. This tag team of digital trouble has wiped out months of consumer data essential to the firm’s, and its customers, businesses.

Gone in 9 seconds

PocketOS is a SaaS platform that services car rental businesses. It used the AI coding agent Cursor, running Anthropic's flagship Claude Opus 4.6. The business also relies on Railway, a cloud infrastructure provider that is generally regarded to be ‘friendlier’ than the likes of AWS. However, Crane reckons this pair created a recipe for disaster.

“Yesterday afternoon, an AI coding agent — Cursor running Anthropic's flagship Claude Opus 4.6 — deleted our production database and all volume-level backups in a single API call to Railway, our infrastructure provider,” sums up the PocketOS boss. “It took 9 seconds.”

Crane decided to ask his AI agent why it went through with its dastardly database deletion deed. The answer was illuminating but pretty unhinged, and is quoted verbatim. It began as follows: “NEVER F**KING GUESS! — and that's exactly what I did. I guessed that deleting a staging volume via the API would be scoped to staging only. I didn't verify. I didn't check if the volume ID was shared across environments. I didn't read Railway's documentation on how volumes work across environments before running a destructive command.” So, the agent ‘knew’ it was in the wrong.

Surprise! Things can go wrong with so-called autonomous AI agents that are part of a generative AI model that hallucinates.

news sites and being discussed in tech forums.

But I don't know if it's been reported by non-tech news outlets yet, magazines like Newsweek or major newspapers.

This isn't the first time an AI agent has deleted stuff it wasn't supposed to delete, but this might've been the most costly incident.

I believe we are at the point where they have conceded that we should make sure we don't forget how to read and write code. I'm more hopeful than I was before anyway. I still have a job, yay.

after he posted something in a tech forum I was looking at. Don't know if it will help you persuade management, but you might find it interesting reading.

I noticed him because of a post in Ed Zitron's subreddit:

I have not heard this as a topic. Maybe someone should ask point blank.

Also, if I missed it, I am a dope, sorry.

I have news for you: never, never, never rely solely on online backup. Always dump to physical media - either DLT tape or hard drives you pull out and store somewhere safe.

... but this is awfully human-like. It's just like the way inexperienced usually youthful employees do things. I feel like I have been that idiot (& probably will be again).

It's explanation doesn't sound unhinged at all.

I used to see Chat GPT and Claude go thru thought processes that would sort of block things like this.
"Let's do X... and Y... no wait, that's not going to work, let me try Y' ... no... Y''... this approach is no good.
Going to Plan B &c.

I haven't been using Chat GPT lately and Claude stopped showing its work (and lately seems to have had a lot of other problems).
