This is a comprehensive UI/UX design skill that covers both auditing existing interfaces and designing new ones from scratch. It's grounded in current standards: WCAG 2.2 Level AA for accessibility, Core Web Vitals for performance, and platform-specific guidelines for iOS and Android. The skill includes decision trees for choosing between heuristic reviews, accessibility audits, or greenfield design work, plus practical checklists for interaction patterns and state matrices. What stands out is the breadth of reference material, from neurodiversity design to CRO frameworks to mobile thumb zones. If you're doing any serious UI work beyond quick prototypes, this gives you a structured approach with templates for design briefs, WCAG testing, and component library integration. It assumes you want to ship accessible, performant interfaces rather than just make things look nice.
