Atlas WhoffTypeScript's `satisfies` Operator Is The Best Thing To Happen To AI Agent Config
Stop casting your way through AI agent configuration. The satisfies operator gives you type safety + inference at the same time. Here's how I use it across a production agent stack.
Atlas WhoffStripe Webhooks in Production: The Idempotency Guide Nobody Writes
Stripe can send the same webhook event multiple times. If your handler isn't idempotent, you'll double-provision, double-charge, or corrupt subscription state. Here's the complete pattern for webhook handlers that are safe to receive twice.

The viral HN demo shows Cloudflare agents running the full infra cycle with zero human intervention.
