## What it does

This skill binds coding agents to your existing repository conventions. The installed Tailwind version, design tokens, UI components, class-merging utilities, and CSS entrypoints take priority over defaults. The agent will not install packages, alter integrations, or upgrade framework versions unless you explicitly ask for it.

For Tailwind v4 setups, the agent references v4 rules and matching documentation. It strictly forbids applying v4 syntax to older releases. Guides for `tailwind-variants`, `tw-animate-css`, or `ESLint` are only loaded if those tools exist locally or if your prompt introduces them. Classes must remain statically discoverable for the build engine.

Static class review alone is insufficient. If mappings or sources change, the agent runs the real Tailwind build and inspects the rendered DOM across viewport sizes and color themes. It concludes with an inspection status block such as `### 🎨 Tailwind — ✅ styling updated` and reports verified visual states.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add PaulRBerg/agent-skills --skill tailwind-css -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/tailwind-css/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/tailwind-css/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add PaulRBerg/agent-skills --skill tailwind-css -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/tailwind-css/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add PaulRBerg/agent-skills --skill tailwind-css -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/tailwind-css/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install PaulRBerg/agent-skills tailwind-css
```

2. **Manually: put the files in place**
- File: `.github/skills/tailwind-css/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add PaulRBerg/agent-skills --skill tailwind-css -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/PaulRBerg/agent-skills --path skills/tailwind-css
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/tailwind-css/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add PaulRBerg/agent-skills --skill tailwind-css -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PaulRBerg/agent-skills/tree/HEAD/skills/tailwind-css/SKILL.md

## When to use it
- update component styling without breaking responsive states or dark mode
- migrate project directives and configuration to Tailwind v4
- organize component variants with tailwind-variants
- verify compiled DOM output through real Tailwind builds

## Example prompts
- Update the product card styling while preserving dark mode behavior.
- Migrate our CSS directives to Tailwind v4 and run the build check.
- Add new button variants using tailwind-variants and inspect the rendered DOM.

# Tailwind CSS

Follow the installed Tailwind version and the repository's tokens, components, class-merging utility, CSS entrypoint,
and nearby UI. They take precedence over this skill. Do not add packages, change integration, or migrate versions
without a request and local need.

## Routing

- Apply [coding preferences](references/coding-preferences.md) only where the project is silent.
- For v4 configuration, migration, directives, or generated classes, use [v4 rules](references/tailwind-v4-rules.md) and
  the matching official docs.
- Read [tailwind-variants](references/tailwind-variants.md), [tw-animate-css](references/tw-animate-css.md), or
  [ESLint](references/eslint.md) only when that integration exists locally or the request adds it.

Do not apply v4 syntax to an older installation. Preserve responsive, interaction, accessible, and dark-mode behavior.
Do not redesign beyond the request.

## Completion

Define the intended visual and state change. Reuse local conventions. Keep classes statically discoverable.

If source registration or generated mappings change, run the real Tailwind build and confirm the expected utilities. Run
required repository checks and inspect the changed states at one representative viewport for a small style edit. Broaden
to narrow/wide viewports, themes, and interactions when responsive rules or shared styling changed. When markup is
transformed by JavaScript or a component library, inspect the final DOM too. Textual class review alone is insufficient.
Repeat checks only when subsequent edits affect their evidence.

Finish with `### 🎨 Tailwind — ✅ styling updated` (or `### 🎨 Tailwind — 🔎 inspected, no files written`) and
code-check and rendered-inspection evidence. Use prose for one inspected state and a compact table for several. Add
`### ⚠️ Remaining` only when needed. Keep source UI copy and diagnostics undecorated.
```
