uat-panel turns User Acceptance Testing from a checklist exercise into a conversation. Claude reads the acceptance criteria, walks you through testing each one in the live app, and records what passed, what failed, and any evidence (screenshots, error messages) — so the team has a clean sign-off record without you writing a test plan from scratch.
Use it: after a feature is built and before you accept the work. Pairs naturally with /team (which builds) or any -completed phase.
