What problem does it solve? Frontend components drift into inconsistent spacing, colors, and patterns when a project lacks a single source of truth for design decisions. This Skill establishes that source of truth by generating a complete SYSTEM.md design system document and synchronized CSS variables from any visual reference. ## Core Features & Use Cases - Design Token Extraction: Analyzes screenshots, HTML/CSS, Figma exports, or descriptions to extract colors (in OKLCH), typography, spacing, radius, depth, and interaction patterns. - SYSTEM.md Generation: Produces a structured 13-section design document covering intent, palette, typography, layout, dark mode, and patterns to preserve, with rationale for every token. - CSS Variable Synchronization: Updates packages/app/react/src/index.css with :root and .dark blocks plus Tailwind @theme mappings so every documented token exists in code. - Use Case: When starting a new project's UI from a brand screenshot, run this Skill to produce the full design system before creating any primitives or components. ## Quick Start Generate a design system from this screenshot and write the SYSTEM.md and CSS variables for the project.
