Tailwind CSS v4 utility-first discipline: CSS-first configuration, design tokens via @theme, and principled class composition. Invoke whenever task involves any interaction with Tailwind CSS — writing, reviewing, refactoring, debugging, or understanding utility classes, theme configuration, custom utilities, dark mode, or Tailwind integration with frameworks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Tailwind CSS v4
**Utility classes are the default. Custom CSS is the escape hatch.**
<prerequisite>
**Tailwind builds on CSS fundamentals.** Before writing or reviewing
Tailwind code, invoke the `css` skill to load specificity, box model,
and layout knowledge.
```
Skill(frontend:css)
```
Skip only for trivial class additions where no CSS reasoning is needed.
</prerequisite>
Tailwind CSS uses CSS-first configuration: design tokens live in `@theme`, custom utilities use `@utility`, and there is
no JavaScript configuration file. Constrain yourself to the design system; break out only with intention.

How to install
mdr add xobotyi/cc-foundry/tailwindcss@sha256:4a38320e26b49cbeThe line at the top of this page pins the label git:20261026.61ec950, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
