Check AI work where you are expert and novice

You have spent 6 years on payments backends and almost no time on frontend styling. One afternoon you ask an AI agent for 2 things. One is a new idempotency key scheme for your refund endpoint in Go. The other is a responsive pricing table in React and CSS for the marketing site.

How much do you trust each result, and how does your way of checking differ between the domain you know and the one you don't?
