tailwind is a cursor rule for Cursor from kensaurus/cursor-kenji. It costs 0 tokens per session (408 once invoked), scanned A, original, MIT.

Tailwind CSS rules define how to style interfaces with shared design tokens, responsive layouts, dark mode, accessible touch targets, and restrained animation. Tailwind CSS is a utility-based styling system.

In plain words
What is it for?
Use them when styling React interfaces, composing conditional classes, supporting different screen sizes, adding dark mode, or implementing motion.
Why use it?

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tailwind scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Tailwind & Styling Conventions

Performance (LCP images, INP, bfcache) → web-performance.mdc.

Design Tokens

  • Use CSS variables from globals.css (e.g., hsl(var(--primary)))
  • Use semantic color names: bg-primary, text-muted-foreground, border-input
  • Never hardcode hex/rgb values — always use tokens
  • Spacing follows 4px/8px grid system

Class Composition

// Use cn() for conditional classes
className={cn(
  "base-classes",
  variant === "active" && "active-classes",
  className // always spread incoming className last
)}

Responsive

  • Mobile-first: base styles are mobile, sm: md: lg: for larger
  • Breakpoints: sm:640px md:768px lg:1024px xl:1280px
  • Touch targets: minimum 44px height for interactive elements on mobile

Dark Mode

  • Use dark: variant for dark mode overrides
  • Or use CSS variables that automatically switch (preferred)
  • Test all UI in both light and dark modes

Animation

  • Use Tailwind animation utilities when possible
  • For complex animations, use Framer Motion
  • Respect prefers-reduced-motion: motion-safe: / motion-reduce:
  • Keep transitions under 300ms for interactions
  • Only animate transform and opacity (GPU-accelerated)

Anti-patterns

  • No inline styles (style={{}}) — use Tailwind classes
  • No !important — fix specificity instead
  • No arbitrary values unless truly one-off (prefer design tokens)
  • No duplicating existing component styles — extend the component

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
