Tailwind CSS is a utility-first CSS framework for rapidly building custom user interfaces. Instead of writing custom CSS, you compose designs using utility classes directly in your markup. Tailwind v4 introduces CSS-first configuration with theme variables, making it easier to customize your design system.

Manages shadcn components and projects — adding, searching, fixing, debugging, styling, and composing UI. Provides project context, component docs, and usage examples. Applies when working with shadcn/ui, component registries, presets, --preset codes, or any project with a components.json file.
