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 | $0.00034 | $0.03496 |
| Opus 5 | $0.00017 | $0.01748 |
| Sonnet 5 | $0.00007 | $0.00699 |
| Haiku 4.5 | $0.00003 | $0.00350 |
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 yesterday.
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
94% identical to tailwindcss — 7 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.
How it starts
The opening of the file, as written. The whole thing — 587 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TailwindCSS v4 Patterns
Overview
TailwindCSS v4 introduces a CSS-first approach, eliminating the need for JavaScript configuration files. All customization happens directly in CSS using new directives.
Key Changes from v3 to v4
| Feature | v3 | v4 |
|---|---|---|
| Configuration | tailwind.config.js |
CSS @theme directive |
| Content detection | JS array | @source directive |
| Plugin loading | require() in JS |
@plugin directive |
| Custom variants | JS API | @custom-variant directive |
| Custom utilities | JS API | @utility directive |
Browser Support
TailwindCSS v4 requires modern browsers:
- Safari 16.4+
- Chrome 111+
- Firefox 128+
Important: No CSS preprocessors (Sass/Less) needed - Tailwind IS the preprocessor.

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.
