Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionui-componentsExecute the skills CLI command in your project's root directory to begin installation:
Fetches ui-components from yonatangross/orchestkit and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate ui-components. Access via /ui-components in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Beautifully designed, accessible components built on CVA variants, cn() utility, and OKLCH theming.
| Rule | File | Key Pattern |
|---|---|---|
| Customization | rules/shadcn-customization.md |
CVA variants, cn() utility, OKLCH theming, component extension |

| Decision | Recommendation |
|---|---|
| Color format | OKLCH for perceptually uniform theming |
| Class merging | Always use cn() for Tailwind conflicts |
| Extending components | Wrap, don't modify source files |
| Variants | Use CVA for type-safe multi-axis variants |
| Styling approach | Data attributes + Tailwind arbitrary variants |
| Composition | Use asChild to avoid wrapper divs |
| Animation | CSS-only with data-state selectors |
| Form components | Combine with react-hook-form |
asChild to avoid extra DOM elementstabindex > 0 disrupts natural tab order| Resource | Description |
