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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00084 | $0.00478 |
| Opus 5.5 | $0.00034 | $0.00191 |
| Sonnet 5.5 | $0.00017 | $0.00096 |
| Haiku 4.5 | $0.00008 | $0.00048 |
Grade A, and why
tailwind-best-practices 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 1mo 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 CSS v4 Best Practices
Use the bundled references for Tailwind CSS v4 guidance. Consult the linked official documentation when current upstream behavior matters.
Reference Files
Read the relevant file for detailed patterns, code examples, and documentation URLs:
docs-urls.md — Official Documentation URLs
URL tables organized by category (Getting Started, Core Concepts, Layout, Spacing, Sizing, Typography, Backgrounds & Borders, Effects, Transforms & Animation, Interactivity). Use with WebFetch when current upstream behavior needs verification.
v4-syntax.md — Tailwind CSS v4 Core Syntax
CRITICAL: v4 changed significantly from v3. Covers @import "tailwindcss", @theme directive for CSS-based configuration (colors, fonts, spacing), @source for detection, class-based @custom-variant dark plus .dark selectors, @layer components for extraction, and @plugin for plugins.
best-practices.md — Best Practices
Class ordering convention (layout → spacing → sizing → typography → colors → effects → interactive), responsive design (mobile-first, breakpoint reference), component extraction rule (3+ times), theme variables over hardcoded values, accessibility (focus-visible, sr-only, contrast).
anti-patterns.md — v4 Anti-Patterns
v3 → v4 migration table (tailwind.config.js → @theme, @tailwind → @import, etc.), common mistakes (inline styles, px values, duplicate/conflicting utilities).
quick-reference.md — Quick Reference
Response guidelines for helping with Tailwind, example response flow, spacing scale table, common utility patterns (centered content, card, responsive grid, truncation, gradient, fixed header).

What ships with it
5 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.

tailwind-best-practices is a skill published in the GitHub repository gopherguides/gopher-ai (21 stars, last pushed yesterday), licensed MIT. It adds 84 tokens to every session and 478 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings.
