The five-item checklist we run in production on a product whose only users are agents: one-hop discovery, a contract you can paste, keys an agent can get on its own, retry-safe writes, and errors that say what to do next.

Had coffee with a friend yesterday. Smart guy, decade in Silicon Valley. To him, 'AI' meant ChatGPT. He'd never used Codex, Claude Code, or Cowork. The frontier moved twelve months ago and 98% of people, even smart technical ones, haven't noticed.
An AI wrote it. Another AI deployed it. A third one will probably summarize it back to you in your feed tomorrow. That's the product.
