Agent guide

Add the cn helper and the theme color variables the files useWhen: The project has no components.json file.From the collection

The files import cn from @/lib/utils:

import { clsx, type ClassValue } from 'clsx';
import { twMerge } from 'tailwind-merge';

export function cn(...inputs: ClassValue[]) {
  return twMerge(clsx(inputs));
}

Class names such as bg-background, text-muted-foreground, border-border, bg-primary, and rounded-lg resolve through these theme variables. Define them in the global CSS and map each color in the Tailwind theme as hsl(var(--name)), with --radius mapped to borderRadius.lg (md is calc(var(--radius) - 2px), sm is calc(var(--radius) - 4px)).

Nativewind projects: the files assume 1rem is 16px, so pass inlineRem: 16 to Nativewind in metro.config.js:

module.exports = withNativeWind(config, { input: './global.css', inlineRem: 16 });
