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

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.

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.
