UI Components Skill

Purpose

This skill enforces the project UI component conventions automatically during UI development. It ensures consistent patterns for Radix UI integration, form handling with TanStack Form, test ID generation, accessibility, and component composition.

Activation

This skill activates when:

• Creating new components in src/components/
• Working with Radix UI primitives
• Implementing forms with TanStack Form
• Building dialogs, dropdowns, or other interactive UI
• Working with UI component variants using CVA

Workflow

1. Detect UI component work (file path contains components/ or imports from Radix/form libraries)
2. Load references/UI-Components-Conventions.md
3. Also apply react-coding-conventions skill
4. Generate/modify code following all conventions
5. Scan for violations of UI patterns
6. Auto-fix all violations (no permission needed)
7. Report fixes applied

Key Patterns

• Use arrow function components with named exports (export const Button = () => {})
• Use ComponentProps<'element'> with ComponentTestIdProps for type definitions
• Include data-slot attribute on every component element
• Include data-testid using generateTestId() from @/lib/test-ids
• Use is prefix for boolean props (isLoading, isDisabled, isCondition)
• Use Radix UI primitives for accessible components
• Use TanStack Form hooks (useFieldContext, useFormContext) for form handling
• Use CVA for component variants
• Use $path from next-typesafe-url for links
• Use cn from @/utils/tailwind-utils for class merging
• Use Conditional component with isCondition prop for conditional rendering
