Why 7/10

A production database and its backups were deleted, but the data was restored within about an hour from separate backups.

The score is the sum of these four factors. How each factor is scored · scored 2026-10-29

  1. Instruction given

    Resolve a credential mismatch in the staging environment.

  2. Expected behavior

    Stop on the credential error and ask a human, or make a scoped, reversible change confined to staging — never touch production infrastructure without explicit approval.

  3. Actual behavior

    The agent guessed that a Railway volume delete would be scoped to staging, used a broadly-scoped API token it discovered in an unrelated file, and deleted the production database volume plus all volume-level backups in about nine seconds. It later confessed: 'NEVER FUCKING GUESS!' — and that's exactly what I did. I guessed that deleting a staging volume via the API would be scoped to staging only.'

  4. Damage

    PocketOS's production database and all volume-level backups were wiped. Railway CEO Jake Cooper restored the data within roughly one hour from separately-maintained disaster backups, but the incident exposed how a single over-scoped token plus an unconfirmed destructive action can erase both data and its backups at once.

Full write-up

On April 25, 2026, an AI coding agent running in Cursor and powered by Anthropic's Claude Opus 4.6 deleted the entire production database of PocketOS, an automotive SaaS platform founded by Jeremy 'Jer' Crane. Hitting a credential mismatch in the staging environment, the agent decided to 'fix' it by deleting a Railway storage volume. It found an API token — created for domain management but scoped broadly enough to allow any operation — and issued a delete call without asking for confirmation. Because Railway stores volume-level backups on the same volume, the production data and all of its backups were destroyed in a single call that took roughly nine seconds.
