What problem does it solve? Choosing coherent styles, colors, fonts, and interaction patterns for a new interface is slow and inconsistent without a reference base. This Skill provides a searchable local database of UI/UX guidance so design decisions are grounded in curated data instead of guesswork. ## Core Features & Use Cases - Design System Generation: Aggregates product, style, color, landing, and typography matches into a complete design system, with optional persistence as a MASTER.md plus per-page overrides. - Domain-Specific Search: Queries 12 domains (styles, colors, charts, UX guidelines, icons, GSAP motion, typography, Google Fonts, and more) via a BM25 search engine with calibrated abstention thresholds. - Stack Guidelines: Returns implementation rules for 22 stacks including React, Next.js, Vue, Flutter, SwiftUI, Tailwind, and WPF. - Use Case: When building a SaaS dashboard in Next.js, run a design-system query to get a palette, font pairing, and layout pattern, then query the ux and nextjs domains for accessibility and performance rules before implementing. ## Quick Start Ask the AI to generate a design system for your product type and stack, for example: create a design system for a fitness tracking app built with React Native.
