What problem does it solve? Choosing styles, color palettes, typography, and UX patterns for a new interface is slow and inconsistent without a reference system. This Skill provides a searchable design knowledge base and a design system generator so UI decisions are grounded in documented rules rather than guesswork. ## Core Features & Use Cases - Design System Generation: Runs multi-domain searches (product, style, color, landing, typography) and applies reasoning rules to output a complete design system with pattern, palette, fonts, effects, and anti-patterns, optionally persisted as a MASTER.md plus per-page override files. - Domain Search CLI: BM25-based search across CSV databases covering 50+ styles, 161 color palettes, 57 font pairings, 161 product types, 99 UX guidelines, 25 chart types, icons, and Google Fonts. - Stack-Specific Guidelines: Searches best-practice rules for 16 stacks including React, Next.js, Vue, Svelte, SwiftUI, React Native, Flutter, Tailwind, and shadcn/ui. - Use Case: When asked to build a fintech dashboard, run the design-system command to get a recommended pattern, style, full color token table, font pairing, and a pre-delivery checklist before writing any component code. ## Quick Start Ask the AI to generate a design system for your product type, for example: use the ui-ux-pro-max skill to create a design system for a beauty spa booking app called Serenity Spa.
