What problem does it solve? Restyling an existing app to match a brand like Stripe, Linear, or Apple requires manually hunting down every color, font, spacing, and shadow value in the codebase and replacing it consistently, which is error-prone and often breaks visual coherence or functionality. ## Core Features & Use Cases - Systematic Token Mapping: Inventories current design tokens (colors, typography, spacing, shadows, radius) and builds an explicit mapping to the target design system's equivalents. - Layered Transformation: Applies changes in a controlled order — colors, typography, spacing, components, depth, responsive — while preserving component logic, accessibility attributes, and semantic HTML. - Partial Redesigns: Supports scoped restyling such as "make just the header look like Linear" with boundary coherence checks. - Use Case: You have a working dashboard built with Tailwind and want it to look like Notion. The skill loads Notion's DESIGN.md, maps your existing tokens to Notion's palette and typography, and rewrites only the visual CSS. ## Quick Start Ask Claude to redesign your existing dashboard or landing page to look like Linear using the design-md catalog.
