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)
