TYPO3 Skills

A collection of reusable Agent Skills for TYPO3 projects. Each skill teaches an AI coding agent how to perform a specific TYPO3-related task — from building Extbase plugins and Content Blocks to configuring CSP, route enhancers, Playwright VRT, Tailwind v4, or Google integrations.

Skills are project-agnostic: generic placeholders (my-site-package, Vendor\MySitePackage\, config/sites/<site-id>, …) are resolved by the LLM at runtime. No manual find-and-replace needed.
