Applies GAIA's patterns and conventions for all Tailwind styling. Use this skill whenever writing Tailwind class names, combining classes with `cn`, writing conditional classes, or building component variants. Also trigger when the user asks about custom values, defining @theme tokens or CSS variables, naming color/spacing tokens, rem vs px, responsive breakpoints, or avoiding template literal class strings.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Tailwind
Contents: Colors; cn; Conditional classes; Variants with cva; Custom Values; When to create a role token.
## Colors
Every color is a theme role token (`bg-background`, `text-foreground`, `text-muted-foreground`, `bg-primary`, `text-primary-foreground`, `border-input`, `text-destructive`), never a raw palette class or an arbitrary color. The contract and where the token list lives: `apps/web/.claude/rules/tailwind.md`. The light and dark values live in the token, so write one utility, not a `dark:` pair.
```tsx
// BAD, raw palette classes and a dark: pair
return <p className="bg-white text-gray-900 dark:bg-gray-900 dark:text-white" />;
// GOOD, role tokens carry both themes
return <p className="bg-background text-foreground" />;
```
## cn
`cn` is the only class utility. Use it to combine class names in React components instead of template literals or array joins.
```tsx
import {cn} from 'cn';
```
`cn` joins its arguments and merges conflicting utilities, so a component default can be overridden by a caller. Put the caller's `className` last: the later class wins on conflict.
```tsx
import {cn} from 'cn';
// BAD, template literals with potential conflicts

The line at the top of this page pins the label git:20261102.65f04fe, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
