Build and publish custom Filament plugins (Filament is the Laravel admin-panel framework). Use when creating a Filament plugin/package, implementing the Plugin contract, scaffolding from the plugin skeleton, registering assets/resources/pages/render-hooks, making a configurable plugin, testing it, or publishing to Packagist and the filamentphp.com/plugins directory. Targets Filament v4 (v5 shares the same plugin API). For USING Filament (resources/forms/tables), use the laravel-filament skill instead.
