# UI Component Generator

## When NOT to use

- For full-page scaffolding → use `/ss-page`
- For composed multi-component patterns → use `/ss-pattern`
- For tweaking an existing component — just edit the file directly
- For non-StyleSeed projects (no `components/ui/` directory or no Tailwind v4)

Generate a new component: **$0**
Description: $ARGUMENTS

## Instructions

1. First, read the compiled design method:
   - Read `.styleseed/effective-rules.md` and `.styleseed/manifest.json`; resolve if stale
   - Read `css/theme.css` for available design tokens
   - Read `css/recipes.css` for morphology variables and helper classes
   - Read `components/ui/button.tsx` as a reference pattern

2. Follow these conventions strictly:
   - Use `function` declaration (not `const`)
   - Add `data-slot="component-name"` attribute
   - Use `cn()` from `@/components/ui/utils` for all className merging
   - Use `React.ComponentProps<>` for prop typing
   - Always support `className` prop for overrides
   - Use CVA (`class-variance-authority`) if the component has variants
   - Use semantic color tokens (`bg-card`, `text-foreground`) — never inline hex

3. Design token usage:
   - Colors: `text-foreground`, `bg-card`, `text-brand`, `text-muted-foreground`, `border-border`
   - Pattern surfaces: `ss-pattern-surface`; insets/controls/icons use the matching `ss-*` class
   - Primitives use the project token scale; do not hardcode one radius or shadow personality
   - Spacing follows one repeatable selected-recipe rhythm
   - Motion: `duration-[var(--duration-fast)]`, `ease-[var(--ease-default)]`

4. Typography rules:
   - Display (36-48px): `leading-none tracking-[-0.02em]`
   - Heading (18-24px): `leading-snug tracking-[-0.01em]`
   - Body (14-17px): `leading-normal` (default tracking)
   - Caption uppercase (10-13px): `tracking-[0.05em]`
   - Use `size-*` shorthand instead of `w-* h-*`
   - Use `ms-*/me-*` instead of `ml-*/mr-*` (logical properties)

5. Accessibility requirements:
   - Minimum touch target: 44x44px (`min-h-11 min-w-11`)
   - Support `aria-*` attributes passthrough
   - Use `focus-visible:ring-2 focus-visible:ring-ring` for keyboard focus
   - Respect `prefers-reduced-motion` for animations

6. Export the component as a named export (not default)

7. Place the file in the appropriate directory:
   - Primitive/reusable → `src/components/ui/`
   - Composed pattern → `src/components/patterns/`
