What problem does it solve? Choosing consistent styles, color palettes, typography, and UX patterns for web and mobile interfaces is time-consuming and error-prone, especially when reviewing UI code for accessibility and usability issues. ## Core Features & Use Cases - Design System Generation: Produce a complete design system (pattern, style, colors, typography, effects) with reasoning-based recommendations for any product type, and persist it as a Master file with per-page overrides. - Searchable Design Database: 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. - UI Review Checklists: Apply priority-ranked rule categories covering accessibility, touch targets, performance, animation, forms, navigation, and charts to audit existing interfaces. - Use Case: When asked to build a fintech dashboard, run the design-system search to get a matched style, palette, and font pairing, then verify the implementation against the accessibility and responsive-layout checklists. ## Quick Start Ask the assistant to generate a design system for your product type, for example: design a landing page for a beauty spa using the ui-ux-pro-max skill.
