# WP Block Development
## When to use
Use this skill for block work such as:
- creating a new block, or updating an existing one
- changing `block.json` (scripts/styles/supports/attributes/render/viewScriptModule)
- fixing “block invalid / not saving / attributes not persisting”
- adding dynamic rendering (`render.php` / `render_callback`)
- block deprecations and migrations (`deprecated` versions)
- build tooling for blocks (`@wordpress/scripts`, `@wordpress/create-block`, `wp-env`)
