What problem does it solve? Choosing consistent styles, color palettes, typography, and layouts for web and mobile interfaces requires extensive design knowledge, and inconsistent choices lead to unprofessional UI with accessibility and usability issues. ## Core Features & Use Cases - Design System Generation: Runs multi-domain BM25 searches across style, color, typography, landing pattern, and product CSV databases, then applies reasoning rules to output a complete design system with anti-patterns to avoid. - Domain and Stack Search: Queries 10 domains (style, color, chart, landing, product, ux, typography, icons, react, web) and 13 stack guideline sets including React, Next.js, Vue, Svelte, SwiftUI, Flutter, and shadcn/ui. - Design System Persistence: Saves generated systems as a MASTER.md source of truth with per-page override files for hierarchical retrieval across sessions. - Use Case: When asked to build a landing page for a beauty spa, run the design-system command to receive a recommended pattern, glassmorphism or minimalism style, hex color palette, Google Fonts pairing, and a pre-delivery checklist before writing any code. ## Quick Start Ask the AI to generate a design system for your project, for example: "Create a design system for a fintech SaaS dashboard using the ui-ux-pro-max skill."
