Skill UI

A comprehensive guide for implementing the Glassmorphism aesthetic across web and mobile applications. Learn the core principles, including backdrop filtering, semi-transparent backgrounds, and light borders, to create a modern, frosted glass look inspired by macOS and contemporary digital interfaces. Includes code examples for CSS, SwiftUI, and Flutter.

StyleSeed Design Review analyzes UI/frontend code (React/Tailwind/HTML) against a detailed design rubric. It scores the interface (0-100) across coherence, color discipline, hierarchy, and polish. The tool pinpoints specific violations—such as mixed corner radii or non-semantic colors—and generates a prioritized, actionable list of fixes, ensuring the final product looks professional and polished, not generic or 'AI-generated.'

This skill prevents AI coding agents from generating generic interfaces by leveraging over 800,000 real web and iOS screens. It helps define design contracts, cover required states, and enforce quality gates during design, implementation, or review. Compatible with agents like Cursor, Copilot, and Claude Code, it ensures product-specific UIs grounded in actual user experience rather than hallucinated patterns.

Design, implement, review, or refactor native macOS 27 Golden Gate interfaces in SwiftUI or AppKit. Ensures apps match Apple's current macOS 27 UI kit with restrained Liquid Glass language, integrated windows, full-height sidebars, native toolbars, flat lists, and clear pane boundaries. Ideal for Figma design-to-code work and audits of boxed interfaces.

A comprehensive guide detailing the aesthetic and technical implementation of AI-native user interfaces for web and mobile applications. It emphasizes conversational flow, adaptive layouts, and generative state visual cues, providing CSS, SwiftUI, and Flutter code examples.

A comprehensive style guide for implementing the Cyber Y2K aesthetic across web and mobile applications. This design package captures the retro-futuristic blend of late 90s/early 2000s digital culture, modern glitch art, and iridescent holographic gradients. It provides detailed code examples using CSS, SwiftUI, and Flutter to achieve key effects like RGB splitting, animated gradients, and aggressive vector typography.

This comprehensive guide outlines the core principles for implementing effective and aesthetically pleasing dark mode across multiple platforms. It covers critical rules such as avoiding pure black backgrounds, defining elevation using lightness contrast, and utilizing desaturated accent colors to reduce eye strain. Detailed code examples for Web (CSS), iOS (SwiftUI), and Flutter are provided, ensuring a premium, high-fidelity user experience.

A comprehensive guide for implementing Flat Design 2.0 (Semi-Flat). This style maintains the clean, solid aesthetic of flat design while introducing subtle, diffuse shadows and micro-gradients to enhance perceived depth and communicate element interactability (e.g., buttons, cards). It provides detailed, cross-platform code examples for Web (CSS), iOS (SwiftUI), Flutter, and React Native.

Provides comprehensive guidelines and code examples (CSS, SwiftUI, Flutter) for implementing modern, dynamic gradient designs. Ideal for projects needing vibrant transitions, animated backgrounds, and an energetic, contemporary aesthetic. Learn how to apply complex color blending to backgrounds, text, and borders across major platforms.

This skill creates or updates a shared Apple design context document for other HIG skills. It auto-discovers project details from code and assets, then gathers information on product overview, platforms, technology stack, design system, accessibility, and user context. The output is a structured markdown file used to tailor subsequent design guidance.

Generate images with Google Gemini's image model straight from a Claude Code session. Create UI placeholders, icons, documentation illustrations, diagrams and concept visuals, saved locally as PNG files with a returned file path.

A comprehensive guide detailing the implementation of the Neo-Brutalist design aesthetic. It specifies core principles, including hard drop shadows, thick black outlines, and high-contrast flat colors. Includes detailed, platform-specific code examples for Web (CSS), SwiftUI, and Flutter, helping developers achieve a playful yet structured, high-impact UI look.
