What problem does it solve? Building interfaces that match xAI's dark-first, monospace-driven visual identity requires exact design tokens that are hard to reverse-engineer manually. This Skill provides the complete color palette, typography scale, component styles, and layout rules so generated UI matches xAI's brand without guesswork. ## Core Features & Use Cases - Complete Design Tokens: Exact color values (background #1f2228, white opacity scales), typography specs (GeistMono display, universalSans body), spacing scale, and border radius rules. - Component Specifications: Detailed styling for buttons, cards, navigation, badges, and form inputs, including hover and focus states with xAI's distinctive dim-on-hover behavior. - Light and Dark Previews: Bundled HTML preview files (preview.html and preview-dark.html) that visualize every token and component for visual verification. - Use Case: When asked to build a landing page or dashboard styled like x.ai, invoke this Skill to generate a hero section with a 320px-weight-300 GeistMono headline, uppercase tracked monospace buttons, sharp 0px-radius cards, and zero box shadows. ## Quick Start Use the design-x.ai skill to create a dark landing page for a developer API product styled like xAI's website.
