 * ## Working with Abilities

 * Register abilities on the `wp_abilities_api_init` action hook, the recommended

 * ## Best Practices
 *
 * - Always register abilities on the `wp_abilities_api_init` hook.
 * - Register abilities on the `wp_abilities_api_init` hook, the recommended
 * deterministic registration point.
 * - Use namespaced ability names to prevent conflicts.
 * - Implement robust permission checks in permission callbacks.
 * - Provide an `input_schema` to ensure data integrity and document expected inputs.
