Core Components

When to Use

Use this skill when you need core component library and design system patterns. Use when building UI, using design tokens, or working with the component library.

Design System Overview

Use components from your core library instead of raw platform components. This ensures consistent styling and behavior.

Design Tokens

NEVER hard-code values. Always use design tokens.

Spacing Tokens

// CORRECT - Use tokens
<Box padding="$4" marginBottom="$2" />

// WRONG - Hard-coded values
<Box padding={16} marginBottom={8} />

Token	Value
$1	4px
$2	8px
$3	12px
$4	16px
$6	24px
$8	32px

Color Tokens

// CORRECT - Semantic tokens
<Text color="$textPrimary" />
<Box backgroundColor="$backgroundSecondary" />

// WRONG - Hard-coded colors
<Text color="#333333" />
<Box backgroundColor="rgb(245, 245, 245)" />

Semantic Token	Use For
$textPrimary	Main text
$textSecondary	Supporting text
$textTertiary	Disabled/hint text
$primary500	Brand/accent color
$statusError	Error states
$statusSuccess	Success states

Typography Tokens

<Text fontSize="$lg" fontWeight="$semibold" />

Token	Size
$xs	12px
$sm	14px
$md	16px
