shadcn

Manages shadcn components and projects — adding, searching, fixing, debugging, styling, and composing UI, including chat interfaces. Provides project context, component docs, and usage examples. Applies when working with shadcn/ui, component registries, presets, --preset codes, or explicit shadcn requests. A components.json file alone does not select this skill for unrelated components; Base UI + StyleX components use base-ui-stylex. Also triggers for "shadcn init", "create an app with --preset", or "switch to --preset".
