add_action( 'wp_abilities_api_categories_init', function() {
    wp_register_ability_category( 'my-plugin', [
        'label' => __( 'My Plugin', 'my-plugin' ),
    ] );
} );

// 2. Then register abilities
add_action( 'wp_abilities_api_init', function() {
    wp_register_ability( 'my-plugin/get-info', [
        'label'       => __( 'Get Site Info', 'my-plugin' ),
        'description' => __( 'Returns basic site information.', 'my-plugin' ),
        'category'    => 'my-plugin',
        'callback'    => 'my_plugin_get_info_callback',
        'meta'        => [ 'show_in_rest' => true ],

```bash
# Profile bootstrap stages
wp profile stage --path=/var/www/html
# Output shows time spent in: bootstrap, main_query, template

# Profile specific hooks
wp profile hook --url=https://mysite.com/slow-page/ --path=/var/www/html

# Profile a specific code path
wp profile eval 'get_option("siteurl");' --path=/var/www/html

# Run doctor checks for common issues
wp doctor check --path=/var/www/html
```
