Skill UI

This comprehensive guide acts as an expert framework for developing a complete, accessible design system using Neumorphism principles. It provides structured instructions covering visual foundations, design tokens, component states (default, hover, error, etc.), accessibility requirements (WCAG 2.2 AA), and content standards, ensuring engineers and designers build consistent and highly usable interfaces.

This skill performs a comprehensive usability audit and heuristic evaluation of interactive user interfaces (UIs). It goes beyond mere visual aesthetics, assessing whether a system is intuitive, easy to learn, and functional for a first-time user. Use it when auditing complex tools, editors, or apps to ensure the user can complete primary tasks without needing extensive instructions or guidance.
