Cloudflare Durable Objects alarm loop drives US$10,000 bill
The billing risk comes from design choices AI code generators routinely make, such as refreshing alarms before expiry, which silently chains invocations forever. Teams deploying on Cloudflare should add alarm-stop rules to agents.md and have a second model review any alarm-renewal logic. Unlike AWS Step Functions, Durable Objects lack a hard spending cap, so cost control depends entirely on the developer's own guardrails.
