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 | $0.00151 | $0.00809 |
| Opus 5.5 | $0.00060 | $0.00324 |
| Sonnet 5.5 | $0.00030 | $0.00162 |
| Haiku 4.5 | $0.00015 | $0.00081 |
Grade A, and why
tailwindcss-development 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 2mo 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
91% identical to tailwindcss-development — 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 Development
Documentation
Use search-docs for detailed Tailwind CSS v4 patterns and documentation.
Basic Usage
- Use Tailwind CSS classes to style HTML. Check and follow existing Tailwind conventions in the project before introducing new patterns.
- Offer to extract repeated patterns into components that match the project's conventions (e.g., Blade, JSX, Vue).
- Consider class placement, order, priority, and defaults. Remove redundant classes, add classes to parent or child elements carefully to reduce repetition, and group elements logically.
Tailwind CSS v4 Specifics
- Always use Tailwind CSS v4 and avoid deprecated utilities.
corePluginsis not supported in Tailwind v4.
CSS-First Configuration
In Tailwind v4, configuration is CSS-first using the @theme directive — no separate tailwind.config.js file is needed:
@theme {
--color-brand: oklch(0.72 0.11 178);
}
Import Syntax
In Tailwind v4, import Tailwind with a regular CSS @import statement instead of the @tailwind directives used in v3:
- @tailwind base;
- @tailwind components;
- @tailwind utilities;
+ @import "tailwindcss";
Replaced Utilities
Tailwind v4 removed deprecated utilities. Use the replacements shown below. Opacity values remain numeric.
| Deprecated | Replacement |
|---|---|
| bg-opacity-* | bg-black/* |
| text-opacity-* | text-black/* |
| border-opacity-* | border-black/* |
| divide-opacity-* | divide-black/* |
| ring-opacity-* | ring-black/* |
| placeholder-opacity-* | placeholder-black/* |
| flex-shrink-* | shrink-* |
| flex-grow-* | grow-* |
| overflow-ellipsis | text-ellipsis |
| decoration-slice | box-decoration-slice |
| decoration-clone | box-decoration-clone |
Spacing
Use gap utilities instead of margins for spacing between siblings:
<div class="flex gap-8">
<div>Item 1</div>
<div>Item 2</div>
</div>
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.
