UI Component

Overview

Part of StyleSeed, this skill generates components that respect the Toss seed's design language instead of improvising ad hoc markup and styling. It emphasizes semantic tokens, predictable typing, reusable variants, and mobile-friendly accessibility defaults.

When to Use

• Use when you need a new UI primitive or composed component inside a StyleSeed-based project
• Use when you want a component to match the existing Toss seed conventions
• Use when a component should be reusable, typed, and design-token driven
• Use when the AI might otherwise invent spacing, colors, or interaction patterns

How It Works

Step 1: Read the Local Design Context

Before generating code, inspect the seed's source of truth:

• CLAUDE.md for conventions
• css/theme.css for semantic tokens
• at least one representative component from components/ui/

If the user already has a better local example, follow the local codebase over a generic template.

Step 2: Choose the Correct Home

Place the output where it belongs:

• src/components/ui/ for primitives and low-level building blocks
• src/components/patterns/ for composed sections or multi-part patterns

Do not create a new primitive if an existing one can be extended safely.

Step 3: Follow the Structural Rules

Use these defaults unless the host project strongly disagrees:

• function declaration instead of a const component
• React.ComponentProps<> or equivalent native prop typing
• className passthrough support
• cn() or the project's standard class merger
• data-slot for component identification
• CVA or equivalent only when variants are genuinely needed

Step 4: Use Semantic Tokens Only

Do not hardcode visual values if the design system has a token for them.

Preferred examples:

• bg-card
• text-foreground
• text-muted-foreground
• border-border
• shadow-[var(--shadow-card)]

Step 5: Preserve StyleSeed Typography and Spacing

• Use the scale already defined by the seed
• Prefer multiples of 6px
• Use logical spacing utilities where supported
• Keep display and heading text tight, body text readable, captions restrained

Step 6: Bake in Accessibility

• Touch targets should be at least 44x44px for interactive elements
• Keyboard focus must be visible
• Pass through aria-* attributes where appropriate
• Respect reduced-motion preferences for nonessential motion

Output

Provide:

1. The generated component
2. The target path
3. Any required imports or dependencies
4. Notes on variants, tokens, or follow-up integration work

Best Practices

• Compose from existing primitives before inventing new ones
• Keep the component API small and predictable
• Prefer semantic layout classes over arbitrary values
• Export named components unless the host project uses another standard consistently
