What problem does it solve? Teams struggle to keep AI-generated pages visually consistent with an existing brand or to turn vague brand requirements into concrete, implementable design rules. This Skill closes the loop between extracting or creating a design system and generating real pages that follow it. ## Core Features & Use Cases - Extract from existing products: Analyze code, live websites, or screenshots to produce a design.md documenting tokens, components, layout rules, and anti-patterns with evidence-based rule markers. - Create from brand requirements: Turn brand goals and constraints into a minimal, actionable design.md with concrete token values, semantic roles, and observable behaviors instead of vague adjectives. - Generate and review pages: Implement frontend pages from an existing design.md, then run a structured review loop with mechanical self-checks, manual inspection, and rule write-back. - Use Case: You inherit a marketing site with no documented design system. Use this Skill to extract its typography, color, and spacing rules into design.md, then generate a new landing page that matches the brand and verify it against the original. ## Quick Start Extract the design system from my existing website into a design.md file, then use it to build a new pricing page.
