An expert design system guideline for implementing modern, playful, and visually deep user interfaces using gradient principles. This guide provides engineers and designers with actionable standards covering color tokens, typography scales, component anatomy, interaction states, and WCAG accessibility criteria.

This skill is designed to enhance the overall feel and usability of user interfaces. Currently, this file is undergoing Japanese translation. Please refer to the original English skill file for detailed functionality and usage scenarios.

This skill guides the user to act as an expert author of comprehensive, implementation-ready design system guidelines for a cyber-slick, dark, Matrix-inspired interface. It covers foundational constraints, color tokens, typography scales, component anatomy, accessibility requirements (WCAG 2.2 AA), and content standards, ensuring technical rigor and visual consistency for engineering and design teams.

This comprehensive guide teaches how to author rigorous, implementation-ready design system documentation. It establishes foundational tokens (colors, spacing, typography) and defines component anatomy across all states (e.g., default, focus-visible, error). The focus is on creating accessible, high-contrast, bold interfaces that comply with WCAG 2.2 AA standards.

This comprehensive guide acts as an expert framework for developing a complete, accessible design system using Neumorphism principles. It provides structured instructions covering visual foundations, design tokens, component states (default, hover, error, etc.), accessibility requirements (WCAG 2.2 AA), and content standards, ensuring engineers and designers build consistent and highly usable interfaces.

Provides expert-level, implementation-ready guidelines for Skeuomorphism design systems. It covers foundational elements like color palettes, typography scales, and spacing rules, combined with WCAG 2.2 AA accessibility standards. Users can build intuitive, familiar, and highly relatable digital interfaces by mimicking real-world textures and physical metaphors.

This comprehensive guide provides expert, implementation-ready guidelines for building narrative-driven digital experiences. It covers foundational elements like visual style, typography, color tokens, and spacing, alongside strict component rules and accessibility standards (WCAG 2.2 AA). Use it to transform functional interfaces into emotionally resonant and memorable user journeys.

A comprehensive, implementation-ready guide for building editorial interfaces. This system defines foundational tokens, typography (DM Serif Display), color palettes, and accessibility standards (WCAG 2.2 AA) to create clean, readable, and aesthetically rich long-form content layouts, perfect for blogs and storytelling platforms.

This comprehensive guide provides expert, implementation-ready design system guidelines for creating a high-contrast, playful, and premium user interface inspired by Tetris. It covers typography, color tokens, spacing, accessibility (WCAG 2.2 AA), and a detailed component authoring workflow, ensuring consistency and usability across all platforms.

nano-pdf is a powerful command-line interface (CLI) tool designed to simplify PDF editing. Instead of requiring complex manual adjustments, users can provide natural language instructions (e.g., "Change the title to X and fix the typo") to modify specific pages of a PDF document. It is ideal for quick content revisions, report updates, or proofreading when traditional PDF editors are cumbersome, offering a highly intuitive workflow.

This comprehensive skill serves as an entry point for all web UI design needs, covering components, pages, dashboards, and advanced layouts using React, Vue, or pure HTML/CSS. It addresses not only aesthetics and polish (color, typography, spacing) but also deep structural concerns like responsive design, UX auditing, and visual system implementation. Use it whenever a user asks to improve the look, feel, or function of a digital interface.

This skill provides a rigorous, multi-layered audit for User Interfaces, proving layout balance and usability beyond subjective judgment. It combines a deterministic spatial audit (calculating centroid, optical-center, and pixel-oracle balance via explicit math) with a professional usability review based on Nielsen's 10 heuristics, conducted by a separate 'fresh-eyes' judge. Ideal for catching misaligned or poorly structured AI-generated designs.
