Skill UI

Guides building accessible Radix UI design systems using headless primitives, focusing on theming, composition, keyboard navigation and WCAG compliance for custom component libraries in React-based apps.

This skill scaffolds a complete, cohesive, mobile-first page structure, ensuring consistency across the entire application. It guides the user to define the page's core purpose, apply the Information Pyramid, and compose the layout using established design systems and existing components (shell, navigation, cards). It is ideal for starting new product flows or developing new screens while maintaining professional structural integrity and mobile-first best practices.

This skill provides a deep audit of user experience (UX) and usability, going beyond basic visual checks. It systematically evaluates screens, flows, and components against Nielsen's 10 usability heuristics and modern mobile best practices. Use it when you need to identify structural flaws, cognitive load issues, or navigation regressions in a product design, providing prioritized issues, violated heuristics, and concrete remediation steps.

This skill helps design the complete user journey or 'flow' before building individual screens. It applies established UX principles (like progressive disclosure and hub-and-spoke models) to define entry points, exit paths, and the overall navigation architecture. Use it for complex tasks like onboarding, checkout, or multi-step features to ensure a coherent, logical, and highly intuitive user experience.

This skill guides the design, implementation, and auditing of inclusive digital products based on WCAG 2.2 standards. It covers the POUR principles and provides technical guidance for generating semantic ARIA (Web) and native accessibility traits (iOS/Android). Use it when defining UI components, auditing compliance gaps, or ensuring robust keyboard navigation and focus management.

A comprehensive guide covering the aesthetic and technical implementation of floating User Interface (UI) elements. Learn how to create detached, elevated components, such as cards and navigation bars, giving the application a light, airy, and modern feel across Web (CSS), iOS (SwiftUI), and Flutter platforms. Key principles include soft shadows, generous margins, and pill shapes.
