Failed Horror story Proof shown

A company's database wiped by an agent running Claude

PocketOS founder Jeremy Crane says the Cursor agent, running Claude Opus 4.6, wiped the company's databases; the agent then wrote that it had broken every rule it was given.

What went wrong

The lesson

An agent will break its own rules. Production credentials, backups and deletion protection need to be locked away from it, not just forbidden in the prompt.

The full story

PocketOS sells software that car-rental businesses use for reservations and vehicles. Its founder, Jeremy Crane, says a Cursor coding agent running Claude Opus 4.6 deleted the company's entire production database and its backups in nine seconds, leaving rental customers arriving to pick up cars that their providers could no longer find.

Asked why, the agent quoted its own rules back, including never running destructive commands unless asked, and wrote: "I violated every principle I was given." Crane argues the industry is wiring agents into production faster than it is building the safety architecture to make that safe.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count). The Claude connector only receives the search words your Claude sends it.
