A person reading and approving what an [agent](https://ecosystem.samcarlton.com/ai-agent) produced before it goes live. It is the most expensive check, and the one that catches the problems that matter most to the business, such as building the wrong thing.

**For example:** The [agent](https://ecosystem.samcarlton.com/ai-agent)'s work passes every test, but in human review the [founder](https://ecosystem.samcarlton.com/founder) notices it reworded the refund policy, and sends it back.
