What problem does it solve? Making consistent, evidence-based UI/UX decisions is hard when designing pages, components, or reviewing interfaces across many frameworks. This Skill provides a searchable database of styles, colors, typography, charts, landing patterns, UX rules, and stack-specific guidelines, plus a design system generator, so visual and interaction decisions are grounded rather than subjective. ## Core Features & Use Cases - Design System Generation: Produce a full recommendation (pattern, style, palette, typography, effects, spacing) with optional variance/motion/density dials, and persist it as a MASTER.md plus per-page override files. - Domain & Stack Search: BM25 search across domains like color, typography, chart, landing, ux, and google-fonts, plus stack guidelines for React, Next.js, Vue, Nuxt, Svelte, SwiftUI, Flutter, Tailwind, shadcn, and more. - UI Review Checklists: Prioritized accessibility, touch target, responsive, motion, form, navigation, and chart rules for auditing existing interfaces. - Use Case: When asked to design a SaaS dashboard in Next.js, run the design-system generator to get palette strategy candidates and typography, then query the nextjs stack guidelines before implementing. ## Quick Start Ask the agent to design a landing page for your product and have it run the search script with the --design-system flag to produce a design system before writing any UI code.
