Agent billing guardrails need hard kill switches

InfoQ reports an incident where extracted AWS keys led to a one-day $14,000 bill driven by Claude invocations on Bedrock, highlighting that email alerts are too slow for agent-speed failures. Why it matters: Autonomous agents can turn credential exposure or runaway loops into immediate cloud spend. Budget alerts are useful, but hard quotas, scoped credentials, and automatic shutdown paths are the stronger control layer.

Try this: For any agent with paid API or cloud access, set scoped short-lived credentials, per-project quotas, budget alarms, and an automated disable path before expanding autonomy.
