By name: szum-tech-design-system description: > Comprehensive reference for building UI with @szum-tech/design-system — a React component library built on Tailwind CSS 4+ and Radix UI. Use this skill whenever working in a project that imports from @szum-tech/design-system, when building or reviewing UI components, when choosing colors, typography, or layout styles, when deciding which component to use, or when creating new components following this design system's patterns. Covers the full color palette (OKLCH semantic tokens), all typography utility classes, every available component with its variants and props, animation classes, icon imports, and the CVA-based styling system. Always use this skill when the user asks about design tokens, Tailwind classes, or component APIs in the context of this library. allowed-tools: Read, Write, Edit, Glob, Grep

Core Patterns
cn() for class merging
Always use cn() (combines clsx + tailwind-merge) when combining classes:
import { cn } from "@szum-tech/design-system/utils";
className={cn("base-classes", conditional && "extra-class", className)}
asChild pattern (polymorphic rendering)
Most interactive components support asChild via Radix UI Slot:
<Button asChild>
<a href="/about">About</a>
</Button>
data-slot attributes
Components expose data-slot="component-name" for CSS targeting and testing selectors.
CVA variants pattern
Variants are typed via VariantProps<typeof componentVariants> — TypeScript autocompletes all valid values.
Read references/components.md for the full API of every component with variants, props, and usage examples.
