What problem does it solve? Choosing the right style, color palette, typography, and interaction patterns for a web or mobile interface is slow and error-prone, and reviewing UI code for accessibility and usability issues requires deep design knowledge. This Skill provides a searchable database of design rules and a CLI that generates complete, reasoned design systems for any product type. ## Core Features & Use Cases - Design System Generation: Run a single CLI query to get a full design system (pattern, style, colors, typography, effects) with reasoning and anti-patterns, optionally persisted as a Master file plus 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. - UI Review Checklists: Apply a priority-ordered rule set 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 command to get a matched style, palette, and font pairing, then verify the implementation against the accessibility and responsive-layout checklists. ## Quick Start Ask the AI 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 design system recommendations.
