Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versiontailwind-4Execute the skills CLI command in your project's root directory to begin installation:
Fetches tailwind-4 from prowler-cloud/prowler and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate tailwind-4. Access via /tailwind-4 in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Tailwind class exists? → className="..."
Dynamic value? → style={{ width: `${x}%` }}
Conditional styles? → cn("base", condition && "variant")
Static only? → className="..." (no cn() needed)
Library can't use class?→ style prop with var() constants
// ❌ NEVER: var() in className
<div className="bg-[var(--color-primary)]" />
<div className="text-[var(--text-color)]" />
// ✅ ALWAYS: Use Tailwind semantic classes
<div className="bg-primary" />
<div className="text-slate-400" />
// ❌ NEVER: Hex colors in className
<p className="text-[#ffffff]" />
<div className="bg-[#1e293b]" />
// ✅ ALWAYS: Use Tailwind color classes
<p className="text-white" />
<div className="bg-slate-800" />
import { clsx } from "clsx";
import { twMerge } from "tailwind-merge";
export function cn(...inputs: ClassValue[]) {
return twMerge(clsx(inputs));
}
// ✅ Conditional classes
<div className={cn("base-class", isActive && "active-class")} />
// ✅ Merging with potential conflicts
<button className={cn("px-4 py-2", className)} /> // className might override
// ✅ Multiple conditions
<div className={cn(
"rounded-lg border",
variant === "primary" && "bg-blue-500 text-white",
variant === "secondary" && "bg-gray-200 text-gray-800",
disabled && "opacity-50 cursor-not-allowed"
)} />
// ❌ Static classes - unnecessary wrapper
<div className={cn("flex items-center gap-2")} />
// ✅ Just use className directly
<div className="flex items-center gap-2" />
When libraries don't accept className (like Recharts):
// ✅ Constants with var() - ONLY for library props
const CHART_COLORS = {
primary: "var(--color-primary)",
secondary: "var(--color-secondary)",
text: "var(--color-text)",
gridLine: "var(--color-border)",
};
// Usage with Recharts (can't use className)
<XAxis tick={{ fill: CHART_COLORS.text }} />
<CartesianGrid stroke={CHART_COLORS.gridLine} />
// ✅ style prop for truly dynamic values
<div style={{ width: `${percentage}%` }} />
<div style={{ opacity: isVisible ? 1 : 0 }} />
// ✅ CSS custom properties for theming
<div style={{ "--progress": `${value}%` } as React.CSSProperties} />
<div className="flex items-center justify-between gap-4" />
<div className="flex flex-col gap-2" />
<div className="inline-flex items-center" />
<div className="grid grid-cols-3 gap-4" />
<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-4 gap-6" />
// Padding
<div className="p-4" /> // All sides
<div className="px-4 py-2" /> // Horizontal, vertical
<div className="pt-4 pb-2" /> // Top, bottom
// Margin
<div className="m-4" />
<div className="mx-auto" /> // Center horizontally
<div className="mt-8 mb-4" />
<h1 className="text-2xl font-bold text-white" />
<p className="text-sm text-slate-400" />
<span className="text-xs font-medium uppercase tracking-wide" />
<div className="rounded-lg border border-slate-700" />
<div className="rounded-full shadow-lg" />
<div className="ring-2 ring-blue-500 ring-offset-2" />
<button className="hover:bg-blue-600 focus:ring-2 active:scale-95" />
<input className="focus:border-blue-500 focus:outline-none" />
<div className="group-hover:opacity-100" />
<div className="w-full md:w-1/2 lg:w-1/3" />
<div className="hidden md:block" />
<div className="text-sm md:text-base lg:text-lg" />
<div className="bg-white dark:bg-slate-900" />
<p className="text-gray-900 dark:text-white" />
// ✅ OK for one-off values not in design system
<div className="w-[327px]" />
<div className="top-[117px]" />
<div className="grid-cols-[1fr_2fr_1fr]" />
// ❌ Don't use for colors - use theme instead
<div className="bg-[#1e293b]" /> // NO
