Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.00724 |
| Opus 5 | $0.00020 | $0.00362 |
| Sonnet 5 | $0.00008 | $0.00145 |
| Haiku 4.5 | $0.00004 | $0.00072 |
Grade A, and why
tailwindcss 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 5d 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.
This is a copy
100% identical to tailwindcss — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Tailwind CSS — Utility-first Styling Skill
When to use
- Rapid UI building with consistent spacing/typography scales
- Design systems where composition beats bespoke CSS
- Component-driven apps (React/Vue/Svelte), marketing pages, prototypes → production
Key concepts & patterns
- Utilities compose in HTML/JSX:
class="flex gap-4 p-6 bg-zinc-950 text-white" - Responsive variants:
sm: md: lg: xl:etc. - State variants:
hover:,focus:,active:,disabled:,group-hover:,peer-checked: - Arbitrary values (use sparingly):
w-[42rem],bg-[#0b1220],translate-y-[3px] - Dark mode patterns:
dark:with class-based strategy - Extracting repeated patterns:
- Prefer components (JSX/Vue components) first
- Then
@applyfor small reusable patterns (avoid overuse)
- Build pipeline:
- Tailwind scans “content” files for class names and generates CSS (zero-runtime)
Common pitfalls
- Classes not generated in production
- Ensure content paths include all templates/components.
- Avoid building class names dynamically (e.g.
"text-" + color) unless safelisted.
- Overusing
@applyand losing the utility-first benefits - Conflicting styles due to class order assumptions
- Huge HTML class lists with no structure
- Use component composition; break into subcomponents; use
clsx/cvawhen needed.
- Use component composition; break into subcomponents; use
Quick recipes
1) A clean CTA button
<button class="inline-flex items-center justify-center rounded-xl px-5 py-3
bg-indigo-600 text-white font-medium
hover:bg-indigo-500 active:bg-indigo-700
focus:outline-none focus:ring-2 focus:ring-indigo-400/60">
Get started
</button>
2) Responsive hero layout
<section class="mx-auto max-w-6xl px-6 py-16">
<div class="grid gap-10 lg:grid-cols-2 lg:items-center">
<div>
<h1 class="text-4xl font-semibold tracking-tight sm:text-5xl">

What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
