Skill UI

Guidelines for reviewing UI code against web interface best practices, covering accessibility, performance, responsive design, component patterns, CSS practices, security, and internationalization during audits or UX evaluations.

A powerful tool for creating professional, animation-rich, and zero-dependency HTML presentations. It supports generating pitch decks, workshop materials, or internal talks from scratch, or converting existing .ppt/.pptx files. The system ensures mandatory viewport fitting, responsiveness across all devices, and includes advanced features like keyboard/touch navigation and reveal animations, resulting in production-quality, modern web presentations.

A comprehensive guide detailing best practices for building beautiful, high-performance, and native-feeling applications using Expo Router. Covers fundamentals, advanced styling, component patterns, complex navigation, animations (Reanimated), native controls, and ensuring platform responsiveness for both iOS and Android.

A comprehensive guide for managing user interactions and system lifecycle events within the Makepad UI framework. It covers handling various input types (mouse, touch, keyboard), lifecycle events (Startup, Shutdown), and propagating custom actions between widgets and their parents. Essential for building highly responsive and interactive graphical user interfaces.

This skill acts as an expert resource for the Makepad layout system. It helps users generate correct layout code and explain advanced UI concepts like flow direction, alignment, padding, and spacing. Use it when positioning, aligning, or structuring widgets in a Makepad application, ensuring responsive and complex UI compositions.

Analyze website images for SEO and performance issues, including alt text quality, file size, formats, responsive delivery, lazy loading, CLS prevention, and optimization opportunities such as WebP/AVIF conversion.

A comprehensive guide to diagnosing and resolving performance bottlenecks in React applications. This skill teaches advanced techniques like state isolation, memoization (using `useMemo`, `useCallback`, and `React.memo`), and list virtualization. It guides users through profiling using React DevTools to identify render hotspots, ensuring components render efficiently and maintain high application responsiveness.

A comprehensive guide for building production-quality, highly accessible, and responsive user interfaces. Covers advanced topics including component architecture (composition over configuration), robust state management patterns (Context, Redux, Server State), adherence to design systems, and meeting WCAG accessibility standards. Use this skill when developing or refining complex user-facing components that require professional polish and maintainability.

A general-purpose skill for writing and executing end-to-end (E2E) browser automation tests using Playwright. It handles complex scenarios such as login flows, form submission, responsive viewport testing, and checking for broken links. The skill automatically detects local development servers and executes custom scripts in a safe, temporary directory, providing real-time debugging and results visualization.

This tool performs a comprehensive audit of website images to ensure optimal SEO and web performance. It checks for proper alt text descriptions, recommends modern formats (WebP, AVIF), validates file sizes, and verifies responsive image implementation using `srcset` and `sizes`. Furthermore, it guides best practices for lazy loading, prioritizing LCP images, and preventing Cumulative Layout Shift (CLS) by checking for dimensions.

This skill provides a comprehensive review of UI components and codebases to ensure strict adherence to established design systems, accessibility guidelines (WCAG), and modern front-end best practices. It checks for design token compliance (e.g., semantic colors, scaled spacing), component conventions, WCAG accessibility standards (a11y), mobile responsiveness, and visual coherence across the entire application.

This guide addresses the performance degradation when automating Apple Notes, especially with large note collections (10,000+). It details architectural patterns, caching strategies, and scripting best practices (like batch processing and incremental sync) to prevent bottlenecks caused by excessive IPC calls, ensuring automation remains responsive at scale.
