Coolify is a self-hosted platform for managing servers and deploying applications, databases, static sites, and other services on hardware controlled by the user. Developers and teams use it as an alternative to hosted application platforms such as Heroku, Netlify, and Vercel, while the catalogue entries help coding agents operate Coolify.

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 | $0.00151 | $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 29d 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.

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.

tailwindcss-development is a skill published in the GitHub repository coollabsio/coolify (65,330 stars, last pushed today), licensed Apache-2.0. It adds 151 tokens to every session and 809 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
