How to use the Tailwind Design System agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The tailwind-design-system skill is a set of instructions that an AI coding agent loads so it can set up Tailwind CSS version 4 for a website or app in a consistent way. It covers shared design settings such as colors, radius, animations and dark mode, written as CSS variables, plus standard patterns for reusable components and responsive, accessible layouts. This guide shows you how to install the skill, ask for work in plain language, and check the results.
Tailwind Design Systemwshobson/agents · MIT Download the skill Quick start
- 1Download the ZIP. Download the tailwind-design-system skill ZIP from this page.
- 2Unzip it into a skills folder. Place the unzipped folder in ~/.claude/skills/ for all projects, or in your project's .claude/skills/ folder for one project.
- 3Confirm your project uses Tailwind v4. Make sure your project has a CSS build setup that runs Tailwind CSS version 4.
- 4Ask for design system work. Describe the task in plain language, such as creating a component library or setting up color tokens in Tailwind v4.
- 5Review the generated CSS and components. Check token names, light and dark mode, and component variants against your existing code.
- 6Build and test. Run your build and check both light and dark themes before committing the changes.
What the skill makes the agent do
When the skill is active, the agent follows its guide to configure Tailwind CSS v4 using CSS-first configuration: the theme is defined with an @theme block in your CSS file instead of a tailwind.config file. The skill sets up semantic color tokens such as background, foreground, primary, muted, destructive and border, defined in OKLCH color values, along with radius tokens and animation tokens.
It also includes a dark mode override using a class-based custom variant, and it explains how to move older Tailwind v3 setups to v4. Its reference files add component patterns, such as button variants built with class-variance-authority, and native CSS animation patterns.
Install the skill from the ZIP
Download the skill ZIP from this page and unzip it. You can install it in one of two places. For a personal setup that applies to all your projects, unzip it into ~/.claude/skills/. For a single project, unzip it into that project's .claude/skills/ folder.
In the Claude apps, you can instead upload the ZIP under Settings → Capabilities → Skills.
- Personal: ~/.claude/skills/
- Single project: .claude/skills/ inside your project
- Claude apps: Settings → Capabilities → Skills (upload the ZIP)
Check what you need before you start
The skill requires an existing Tailwind CSS v4 project, meaning a CSS build setup that runs Tailwind. It does not create a project from scratch or provide a finished visual design. It supplies patterns and starter code that you adapt to your codebase.
The skill does not run scripts and does not use the network, according to its listing.
- Tailwind CSS v4 project with a CSS build setup
- Projects still on Tailwind v3 should plan an upgrade first, because the guide uses v4 syntax
Trigger the skill with natural requests
You do not need a special command. The skill is meant to be used when you ask for design system work. Its description covers creating component libraries, implementing design systems and standardizing UI patterns, so requests that match those topics are the ones it is built for. Name Tailwind v4 in your request to make the target clear.
- Set up Tailwind v4 design tokens for colors, radius and dark mode in my app's CSS.
- Create a reusable Button component with primary, secondary and destructive variants in Tailwind v4.
- Standardize spacing and color usage across our components using Tailwind v4 theme variables.
- Help me migrate this project's tailwind.config.js setup from Tailwind v3 to v4.
Review the output and adapt it
The skill's starter CSS defines color tokens for light mode and a .dark block that overrides them. Check that the token names match what your components already use, and adjust the OKLCH values to your brand. Keep the dark mode variant consistent: the guide uses @custom-variant dark (&:where(.dark, .dark *)), so dark mode applies when a .dark class is present.
For migrations, the skill's key-changes table maps v3 patterns to v4 equivalents, such as tailwind.config.ts to @theme in CSS, and @tailwind directives to @import "tailwindcss". Run your build after each change to catch differences.
- Confirm token names match existing class usage in your components
- Test both light and dark mode after changes
- Run your build to catch migration differences
@import "tailwindcss";
@theme {
--color-primary: oklch(14.5% 0.025 264);
--radius-md: 0.375rem;
}Safety notes: scripts and network
According to the listing, this skill runs no scripts and uses no network access. It works by giving the agent instructions and code patterns. Like any code the agent writes, the output still lands in your project, so review changes in your version control before committing them.
- Runs scripts: no
- Uses network: no
- Review generated CSS and components before merging
What people use it for
- Setting up semantic color tokens and dark mode in a new Tailwind v4 app
- Building a shared Button or Card component with variants and sizes
- Standardizing colors and radius across several front-end projects
- Migrating a project's Tailwind v3 config to CSS-first v4 configuration
- Adding entry and exit animations with CSS keyframes in the theme
Frequently asked questions
How do I install the tailwind design system skill?
Download the skill ZIP from this page and unzip it into ~/.claude/skills/ for personal use, or into a project's .claude/skills/ folder for one project. In the Claude apps, you can upload the ZIP under Settings → Capabilities → Skills.
What does the tailwind-design-system skill require?
It requires an existing Tailwind CSS v4 project, meaning a CSS build setup that runs Tailwind. It does not run scripts and does not use the network.
Is the tailwind-design-system skill free?
The skill is published under the MIT licence. The source page does not list pricing, so check the repository for the terms that apply to you.
Does this skill work with Tailwind v3?
The guide targets Tailwind CSS v4 syntax, and the config patterns differ from v3. For v3 projects, the skill points to the official upgrade guide, so plan the upgrade first or use the migration guidance it contains.
Why does my dark mode not switch?
The skill's dark mode relies on a .dark class and the custom variant @custom-variant dark (&:where(.dark, .dark *)). Check that the class is applied to a parent element and that your CSS includes the variant and the .dark token overrides.
How does this compare to building a design system by hand?
The skill gives the agent a consistent set of token, variant and migration patterns to start from, which saves setup time. You still need to decide your brand colors, component names and layout, because the skill supplies patterns and starter code rather than a finished design.

Our verdict
Use this skill if you are a front-end developer building a shared component library in Tailwind v4, or a team that wants consistent colors, spacing and dark mode, or a developer moving a project from v3 to v4. Pick something else if your project stays on Tailwind v3 without an upgrade plan, or if you need a finished visual design rather than patterns and starter code.
