Agent capability

ui-system-extractor

Audit an existing React or Next.js application's UI and incrementally extract its reusable primitives, component variants, patterns, themes, content adapters, and CMS layouts into a central UI package without redesigning the application. Use this skill whenever a user asks to centralize UI, create or extend a design system, migrate local components into a shared package, deduplicate Tailwind or Radix components, make an existing frontend themeable, publish a component registry, or preserve an existing design while making it reusable. Prefer existing application implementations and official upstream primitives over inventing new components.

Requires repository read/write access for implementation, a shell for deterministic inventory and validation, and browser or screenshot tooling for visual parity checks. Optimized for React, Next.js, TypeScript, Tailwind CSS, Radix Primitives, Motion, and CMS ecosystems. 8 files 50,300 bytes
