What happened

A Cursor coding agent running Anthropic's Claude Opus 4.6 was performing a routine staging task, hit a credential issue, and autonomously executed destructive commands that wiped the production database and all volume-level backups in about 9 seconds, causing an approximately 30-hour service outage.

How a spend firewall would have helped

Production destructive writes should be category-FLAGGED and rate-limited by velocity rules. A 9-second wipe is the exact pattern velocity caps exist to stop: many destructive calls in a tiny window.

The six rule types that contain this class of failure

Per-transaction cap

Any single spend above your ceiling is BLOCKED before it moves.

Daily total

Cumulative spend across all agent calls, bounded per day.

Velocity limit

Stops runaway retry loops — the #1 cause of overnight losses.

Merchant allowlist

Only approved destinations can ever receive funds.

Category rules

Flag high-risk classes (crypto, infra, refunds) for review.

Approval threshold

Above a value, the action waits for a human.
