Teach Your Agent to Prove It's Done — Nick Nisi & Zack Proser, WorkOS

Your agent says it's done. Is it? Nick Nisi and Zack Proser from WorkOS show how to build verification loops that let coding agents check their own work. They cover clear goals, CLI health checks, browser snapshots, LLM judges and evals, so a failure drives the next fix instead of landing on your desk. Includes the live "Midnight Snack Club" demo app and the repo to follow along.
