What problem does it solve? HeroUI v3 introduced breaking changes from v2—no provider, compound components, Tailwind CSS v4, and new packages—so outdated knowledge produces broken code. This Skill supplies correct v3 patterns and fetches live component documentation, source code, styles, and theme variables on demand. ## Core Features & Use Cases - v3-Correct Implementation Guidance: Enforces compound component patterns (e.g., Card.Header, Card.Title), semantic variants, onPress handlers, and the no-provider architecture. - Live Documentation Fetching: Scripts retrieve component MDX docs, TypeScript source, BEM CSS styles, and oklch theme variables from the HeroUI API with GitHub fallbacks. - Setup & Theming Support: Covers Next.js App Router installation, PostCSS configuration, CSS import order, and dark/light theme switching via data-theme attributes. - Use Case: Ask for a settings page with a Modal and Form; the Skill fetches the latest Modal and Form docs, then generates accessible compound-component code styled with semantic variants. ## Quick Start Ask the assistant to build a HeroUI v3 card component with a header, description, and primary action button for a Next.js app.
