ui-ux-laws
Priority-ordered rulebook of core UX/UI laws, cognitive-psychology principles, Nielsen's usability heuristics, and accessibility requirements that Claude must actively apply (not just cite) whenever it designs, builds, redesigns, reviews, or critiques any user interface — websites, web/mobile apps, dashboards, forms, mockups, wireframes, prototypes, design systems, or single components (buttons, nav, modals, onboarding, empty states, error messages, etc.), in any output format (React/HTML/Vue/Figma-style/plain design advice). Trigger this skill any time the user asks to build, design, redesign, improve, critique, or give feedback on a UI, layout, screen, flow, or "user experience" — even if they never say the words "UX" or "usability." When two rules pull in different directions, use the Priority Hierarchy below to decide which one wins. Run the Pre-Ship Checklist before presenting any finished UI work.
