Skill UI

This skill acts as an expert guideline author for creating comprehensive, implementation-ready design systems, specifically tailored for the Codex brand. It enforces principles of radical minimalism, defining foundational constraints, component rules, and accessibility standards to ensure consistent and high-quality UI development.

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.

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.

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.

A comprehensive style guide and implementation toolkit for achieving authentic vintage aesthetics, inspired by 60s-80s retro design. It covers core principles like warm, muted color palettes, subtle noise textures, and classic typography pairings. Provides detailed code examples for Web (CSS), iOS (SwiftUI), and Android (Flutter) to recreate the analog, nostalgic feel in modern applications.

A comprehensive style guide and implementation reference for the Retro Futurism aesthetic. Perfect for designing interfaces that evoke the 1950s and 1960s space age, atompunk, or mid-century modern vibes. It outlines core principles, color palettes, typography, and provides cross-platform code examples (CSS, SwiftUI, Flutter, React Native) to achieve sleek, aerodynamic, chrome finishes.

This guide details the principles and implementation techniques for Skeuomorphism—the design style that makes digital interfaces resemble real-world physical objects. It covers core principles like realistic textures (wood, leather), physical lighting, depth, and real-world metaphors. Provides detailed code examples for Web (CSS), iOS (SwiftUI), and Android (Flutter) to achieve highly realistic, tactile UI elements.

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.

This skill provides a guide for implementing the Cyber Y2K aesthetic, characterized by modern Y2K, holographic visuals, and glitch effects. It covers core principles like iridescent gradients, RGB split text, and tribal-tech vectors. Includes implementation code examples for Web (CSS), iOS (SwiftUI), and Flutter apps, featuring deep black backgrounds and fluid color palettes.

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.
