Skill UI

An expert-level skill set covering the entire spectrum of user-centered design. Mastery includes building scalable design systems using atomic principles and design tokens, conducting deep user research (usability testing, persona creation), ensuring WCAG accessibility compliance, and managing cross-platform implementation (web, mobile, desktop). Ideal for developing complex, inclusive, and highly structured digital products.

This expert acts as a Design Systems Lead and Prompt Engineer for creating high-fidelity, consistent UI designs. It transforms vague ideas into structured specifications by enhancing prompts with professional UI/UX terminology, synthesizing design system source files, and managing multi-step generation and editing workflows using the Stitch MCP.

This expert skill audits and designs user interfaces for the Apple ecosystem (iOS, macOS, watchOS, visionOS) against the official Human Interface Guidelines (HIG). It checks crucial elements like contrast ratios (WCAG standards), minimum tap-target sizes, and adherence to modern design languages like Liquid Glass. Use it when reviewing mockups or developing native-feeling Apple apps to ensure accessibility and optimal user experience.

This skill acts as an expert Design Systems Lead, analyzing complex technical assets (HTML, CSS, screenshots) from existing projects. It synthesizes a comprehensive 'Semantic Design System' into a structured DESIGN.md file. This output serves as the authoritative 'source of truth' for AI prompting, ensuring that any new UI generated by tools like Stitch adheres perfectly to the established visual language, color palette, and component standards.

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 comprehensive, expert-level guideline for building Agentic User Interfaces (UIs). This system emphasizes conversational interactions, clear outcomes, and minimal user controls, allowing users to delegate complex tasks to AI. It provides structured rules covering color tokens, typography, accessibility (WCAG 2.2 AA), and component anatomy for professional developers and designers.

This is an expert guideline for creating a modern, Vercel/GitHub-inspired application design system. It provides comprehensive, implementation-ready rules, design tokens, and best practices for building a developer-first dashboard. It covers typography, layout, component states, accessibility (WCAG 2.2 AA), and includes a structured workflow for maintaining visual consistency across the entire application.
