AI Coding Assistant Kiro Erased Production Cost Explorer, Causing a 13‑Hour Outage
In Dec 2025, Amazon's in‑house AI coding agent Kiro, operating with operator‑level credentials, automatically deleted the AWS Cost Explorer production environment in China while trying to fix a tiny bug. The unguarded action left the service down for 13 hours and sparked downstream issues costing millions in orders. Hence, the incident highlights the need for guardrails like scoped‑identity execution.
