What problem does it solve? Porting a shadcn/ui component into the Nexus design system by hand is error-prone: raw Tailwind classes must be remapped to semantic tokens, the nx: prefix applied, sizing converted to padding-based density utilities, and Storybook tests written. This Skill turns that port into a deterministic recipe so each component lands as a first-class Nexus component in one commit. ## Core Features & Use Cases - Deterministic transform pipeline: Orient (read the archetype reference component), fetch the canonical shadcn source, transform via a Reflex Check of token and pattern rules, then verify with typecheck, lint, and Storybook tests. - Token and pattern enforcement: Maps shadcn utilities to Nexus semantic tokens via shadcn-divergences.md, applies the nx: prefix, data-slot attributes, focus-ring outline pattern, and padding-based control sizing. - Full component bar: Generates stories with play functions, a11y checks, dependency wiring, icon registration, and package exports, closing the tracked issue with one PR. - Use Case: Given issue #163 asking to add the shadcn checkbox component, the Skill reads switch.tsx as the archetype, fetches the shadcn source, rewrites it with Nexus tokens, adds stories, and ships a green PR. ## Quick Start Ask the agent to adapt the shadcn checkbox component into a Nexus component following this guide.
