Tailwind 4 Validator

Validates that a project uses Tailwind CSS v4 with proper CSS-first configuration. Detects and flags Tailwind v3 patterns that should be migrated.

Purpose

CRITICAL: Claude and other AI assistants often default to Tailwind v3 patterns. This skill ensures:

  • Projects use Tailwind v4 CSS-first configuration
  • Old tailwind.config.js patterns are detected and flagged
  • Proper @theme blocks are used instead of JS config
  • Dependencies are v4+
