What problem does it solve? Choosing the right visual style, color palette, typography, and interaction patterns for a web or mobile product is time-consuming and inconsistent without a structured reference. This Skill provides a searchable design intelligence database so every UI decision is grounded in documented rules and platform guidelines. ## Core Features & Use Cases - Design System Generation: Run a single CLI query to get a complete design system (pattern, style, colors, typography, effects) with reasoning and anti-patterns, optionally persisted as a Master file with per-page overrides. - Domain Search: Query 50+ styles, 161 color palettes, 57 font pairings, 161 product types, 99 UX guidelines, and 25 chart types across 10 stacks including React, Next.js, Vue, SwiftUI, Flutter, and Tailwind. - Priority-Based Review Checklist: Audit existing UI code against ranked rule categories covering accessibility, touch targets, performance, animation, forms, navigation, and charts. - Use Case: When asked to build a fintech dashboard, generate a design system with --design-system, then pull chart and UX rules to implement accessible data visualizations. ## Quick Start Ask the AI to generate a design system for your product type, for example: "Build a landing page for a beauty spa and recommend the style, colors, and fonts."
