This is a comprehensive reference for conducting UX reviews and accessibility audits. It packages Nielsen's heuristics, cognitive psychology laws (Hick's, Fitts's, Miller's), and WCAG 2.2 compliance checks into a single prompt. You'd use it when evaluating interfaces, mapping user journeys, or catching accessibility violations before they ship. The severity rating system and issue templates are immediately practical. What I appreciate is the focus on WCAG 2.2's newer requirements like 24px touch targets and focus appearance, which are easy to miss. It assumes you know when to apply these frameworks rather than walking you through discovery. Best for structured audits where you need checklists and established heuristics at hand.
