What problem does it solve? Recreating the visual language of well-known websites from scratch requires manually reverse-engineering color palettes, typography, spacing, and component styles. This Skill provides ready-made design system specifications so generated HTML/CSS pages match the look of sites like Stripe, Linear, or Vercel without guesswork. ## Core Features & Use Cases - 54 Design System Templates: Each template captures a site's color palette, typography hierarchy, component styles, spacing system, shadows, and responsive behavior with exact CSS values. - Font Substitution Guidance: Maps proprietary fonts (Geist, sohne-var, Circular) to Google Fonts substitutes with ready-to-paste link tags and font-family stacks. - Category-Based Selection: Templates organized by domain (AI, developer tools, fintech, enterprise) with guidance on matching designs to content type. - Use Case: A user asks for a landing page styled like Stripe. The Skill loads the stripe.md template, applies its purple gradient palette, weight-300 typography, and component specs to produce a matching HTML page. ## Quick Start Ask the agent to build a landing page that looks like Linear, and it will load the corresponding design template and generate matching HTML and CSS.
