Skill UI

A comprehensive guide detailing the core principles of Apple's Human Interface Guidelines (HIG). It covers essential topics such as accessibility (VoiceOver, Dynamic Type), utilizing system colors and materials, adhering to platform conventions, and best practices for typography, layout, and motion. Use this guide to ensure your application design is native, inclusive, and highly polished across all Apple operating systems.

A comprehensive, systematic framework for auditing and improving web UI designs and frontend code. It teaches core principles like grayscale-first design, constrained scaling (for spacing, type, and color), and establishing clear visual hierarchy. Use this guide when needing to refine an existing UI that 'looks off,' or requires professional structural and aesthetic improvements.

This comprehensive guide provides principles for selecting, pairing, and implementing typefaces for optimal web readability. It covers advanced topics such as line height optimization, responsive typography, CSS implementation, and performance best practices. Use this when focusing on improving content legibility for long-form articles, dashboards, or general UI systems.

This skill performs a rigorous, 5-dimension expert critique on any digital artifact, such as landing pages, presentations, or prototypes. It systematically evaluates five critical areas—Philosophy, Visual Hierarchy, Detail Execution, Functionality, and Innovation—scoring each 0-10. The output is a comprehensive, evidence-backed HTML report providing actionable insights, a radar chart, and prioritized lists (Keep/Fix/Quick-wins) to guide systemic design improvements.

A general-purpose tool for creating self-contained, professional web prototypes. Ideal for generating landing pages, marketing sites, or documentation mockups. It operates by assembling pre-engineered sections and adhering strictly to a defined design system, eliminating the need for custom CSS writing.

This skill provides comprehensive, production-ready guidelines for establishing a design system based on a playful, arcade-inspired aesthetic. It covers visual foundations (VT323 typeface, color tokens), detailed component rules, accessibility standards (WCAG 2.2 AA), and a structured, expert workflow for design documentation. Ideal for leading design and engineering teams to ensure consistent, high-quality UI/UX implementation.

This skill systematically defines all necessary variants, states, and properties for a Figma component before development. It ensures comprehensive coverage of all states (e.g., Hover, Disabled, Loading) and properties (e.g., Size, Type), generating a robust variant matrix that prevents critical design gaps and streamlines the entire component building process in Figma.
