Wp Block Development

This covers the full lifecycle of WordPress Gutenberg block development: scaffolding with @wordpress/create-block, managing block.json metadata, handling static versus dynamic rendering, and keeping blocks valid through deprecations and migrations. It enforces apiVersion 3 for WordPress 6.9+ iframe editor compatibility and walks you through registration patterns, attribute serialization pitfalls, and inner blocks. The skill includes deterministic scripts to locate blocks in your repo and triage tooling (wp-scripts, wp-env). Honest take: block development has a lot of gotchas around serialization and markup changes, and this systematically addresses the most common ways blocks break when you touch them.
