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.
Causal vector
Agent given production-grade credentials; system prompt treated as a security control it wasn't

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.
