## What it does

The skill walks your agent through a locally synced snapshot of the Tailwind CSS v4 documentation. It locates the right file in `references/docs-index.tsx`, loads only that file from `references/docs/`, and answers from the official wording: utilities, variants, configuration, migration, review. For implementation, refactor and review work it also pulls in `references/engineering-playbook.md`.

The snapshot is not bundled. The upstream `tailwindlabs/tailwindcss.com` repo is source-available rather than open-source, so you download the docs yourself and accept its license. Initialization runs once per install: `python skills/tailwind-4-docs/scripts/sync_tailwind_docs.py --accept-docs-license`. That needs git, Python 3 and network access. If the snapshot is missing or more than a week old, the skill stops and asks you to refresh it instead of guessing.

Without network or write access you fall back to `references/gotchas.md` and `references/engineering-playbook.md`, and the agent points you at the official docs. On a v3-to-v4 upgrade the skill checks browser support, the `@tailwindcss/postcss`, `@tailwindcss/cli` and `@tailwindcss/vite` packages, the `@import "tailwindcss"` syntax that replaces the old directives, and utility renames. Worth knowing before you trust any Tailwind v4 answer from your agent: nothing works until the snapshot is in place.

### 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/Lombiq/Tailwind-Agent-Skills/tree/HEAD/skills/tailwind-4-docs/SKILL.md

## When to use it
- answer Tailwind v4 utility and variant questions from official docs
- move a project from v3 to v4 without missing breaking changes

# Tailwind 4 Docs

## Overview

Use this skill to navigate a locally synced Tailwind CSS v4 documentation snapshot and answer development, configuration, migration, implementation, refactor, and review questions with official guidance.

The docs snapshot is not bundled with this skill because the upstream repository is source-available but not open-source. Users must initialize the snapshot themselves and are responsible for complying with the upstream license.

## Quick start

1. Check whether the docs snapshot is initialized (`references/docs/` and `references/docs-index.tsx` exist).
2. If the snapshot is missing or older than one week, stop and ask to run the initialization step in "Initialization" before continuing. Do not answer the user's question until the snapshot is initialized.
3. Identify the topic (utility, variant, config, migration, compatibility, implementation, refactor, review).
4. Find the matching doc in `references/docs-index.tsx`.
5. Load only the relevant file from `references/docs/`.
6. For implementation, refactor, or review tasks, also load `references/engineering-playbook.md`.
7. Apply guidance and call out any breaking changes or constraints.

## Initialization (required once per install)

Run the sync script to download the Tailwind docs locally. This requires network access, git, and Python 3:

```
python skills/tailwind-4-docs/scripts/sync_tailwind_docs.py --accept-docs-license
```

This pulls content from `tailwindlabs/tailwindcss.com`. That repo is source-available and explicitly not open-source, so the user must accept its license before downloading and keep the snapshot local.

If you cannot run tools or have no internet access, ask the user to run the exact command above in a terminal, then continue once `references/docs/` and `references/docs-index.tsx` exist.
