/**
 * Abilities API: core functions for registering and managing abilities.
 *
 * The Abilities API provides a unified, extensible framework for registering
 * and executing discrete capabilities within WordPress. An "ability" is a
 * self-contained unit of functionality with defined inputs, outputs, permissions,
 * and execution logic.
 *
 * ## Overview
 *
 * The Abilities API enables developers to:
 *
 *  - Register custom abilities with standardized interfaces.
 *  - Define permission checks and execution callbacks.
 *  - Organize abilities into logical categories.
 *  - Validate inputs and outputs using JSON Schema.
 *  - Expose abilities through the REST API.
 *
 * ## Working with Abilities
 *
 * Abilities must be registered on the `wp_abilities_api_init` action hook.
 * Attempting to register an ability outside of this hook will fail and
 * trigger a `_doing_it_wrong()` notice.

* Example:
 *
 *     function my_plugin_register_abilities(): void {
 *         wp_register_ability(
 *             'my-plugin/export-users',
 *             array(
 *                 'label'               => __( 'Export Users', 'my-plugin' ),
 *                 'description'         => __( 'Exports user data to CSV format.', 'my-plugin' ),
 *                 'category'            => 'data-export',
 *                 'execute_callback'    => 'my_plugin_export_users',
 *                 'permission_callback' => function(): bool {
 *                     return current_user_can( 'export' );
 *                 },
 *                 'input_schema'        => array(
 *                     'type'        => 'string',
 *                     'enum'        => array( 'subscriber', 'contributor', 'author', 'editor', 'administrator' ),
 *                     'description' => __( 'Limits the export to users with this role.', 'my-plugin' ),
 *                     'required'    => false,
 *                 ),
 *                 'output_schema'       => array(
 *                     'type'        => 'string',
 *                     'description' => __( 'User data in CSV format.', 'my-plugin' ),
 *                     'required'    => true,
 *                 ),
 *                 'meta'                => array(
 *                     'show_in_rest' => true,
 *                 ),
 *             )
 *         );
 *     }
 *     add_action( 'wp_abilities_api_init', 'my_plugin_register_abilities' );
 *
 * Once registered, abilities can be checked, retrieved, and managed:
 *
 *     // Checks if an ability is registered, and prints its label.
 *     if ( wp_has_ability( 'my-plugin/export-users' ) ) {
 *         $ability = wp_get_ability( 'my-plugin/export-users' );
 *
 *         echo $ability->get_label();
 *     }
 *
 *     // Gets all registered abilities.
 *     $all_abilities = wp_get_abilities();
 *
 *     // Unregisters when no longer needed.
 *     wp_unregister_ability( 'my-plugin/export-users' );
 *
 * ## Best Practices
 *
 *  - Always register abilities on the `wp_abilities_api_init` hook.
 *  - 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.
 *  - Define an `output_schema` to describe return values and validate responses.
 *  - Return `WP_Error` objects for failures rather than throwing exceptions.
 *  - Use internationalization functions for all user-facing strings.

/**
 * Registers a new ability using the Abilities API. It requires three steps:
 *
 *  1. Hook into the `wp_abilities_api_init` action.
 *  2. Call `wp_register_ability()` with a namespaced name and configuration.
 *  3. Provide execute and permission callbacks.
 *
 * Example:
 *
 *     function my_plugin_register_abilities(): void {
 *         wp_register_ability(
 *             'my-plugin/analyze-text',
 *             array(
 *                 'label'               => __( 'Analyze Text', 'my-plugin' ),
 *                 'description'         => __( 'Performs sentiment analysis on provided text.', 'my-plugin' ),
 *                 'category'            => 'text-processing',

 *                     'type'        => 'string',
 *                     'description' => __( 'The text to be analyzed.', 'my-plugin' ),
 *                     'minLength'   => 10,
 *                     'required'    => true,
 *                 ),
 *                 'output_schema'       => array(
 *                     'type'        => 'string',
 *                     'enum'        => array( 'positive', 'negative', 'neutral' ),
 *                     'description' => __( 'The sentiment result: positive, negative, or neutral.', 'my-plugin' ),
 *                     'required'    => true,
 *                 ),
 *                 'execute_callback'    => 'my_plugin_analyze_text',
 *                 'permission_callback' => 'my_plugin_can_analyze_text',
 *                 'meta'                => array(
 *                     'annotations'   => array(
 *                         'readonly' => true,
 *                     ),
 *                     'show_in_rest' => true,
 *                 ),
 *             )
 *         );
 *     }
 *     add_action( 'wp_abilities_api_init', 'my_plugin_register_abilities' );
 *
 * ### Naming Conventions
 *
 * Ability names must follow these rules:
 *
 *  - Include a namespace prefix (e.g., `my-plugin/my-ability`).
 *  - Use only lowercase alphanumeric characters, dashes, and forward slashes.
 *  - Use descriptive, action-oriented names (e.g., `process-payment`, `generate-report`).
 *
 * ### Categories
 *
 * Abilities must be organized into categories. Ability categories provide better
 * discoverability and must be registered before the abilities that reference them:
 *
 *     function my_plugin_register_categories(): void {
 *         wp_register_ability_category(
 *             'text-processing',
 *             array(
 *                 'label'       => __( 'Text Processing', 'my-plugin' ),
 *                 'description' => __( 'Abilities for analyzing and transforming text.', 'my-plugin' ),
 *             )
 *         );
 *     }
 *     add_action( 'wp_abilities_api_categories_init', 'my_plugin_register_categories' );
 *
 * ### Input and Output Schemas
 *
 * Schemas define the expected structure, type, and constraints for ability inputs
 * and outputs using JSON Schema syntax. They serve two critical purposes: automatic
 * validation of data passed to and returned from abilities, and self-documenting
 * API contracts for developers.
 *
 * WordPress implements a validator based on a subset of the JSON Schema Version 4
 * specification (https://json-schema.org/specification-links.html#draft-4).
 * For details on supported JSON Schema properties and syntax, see the
 * related WordPress REST API Schema documentation:
 * https://developer.wordpress.org/rest-api/extending-the-rest-api/schema/#json-schema-basics
 *
 * Defining schemas is mandatory when there is a value to pass or return.
 * They ensure data integrity, improve developer experience, and enable
 * better documentation:
 *
 *     'input_schema' => array(
 *         'type'        => 'string',
 *         'description' => __( 'The text to be analyzed.', 'my-plugin' ),
 *         'minLength'   => 10,
 *         'required'    => true,
 *     ),
 *     'output_schema'       => array(
 *         'type'        => 'string',
 *         'enum'        => array( 'positive', 'negative', 'neutral' ),
 *         'description' => __( 'The sentiment result: positive, negative, or neutral.', 'my-plugin' ),
 *         'required'    => true,
 *     ),
 *
 * ### Callbacks
 *
 * #### Execute Callback
 *
 * The execute callback performs the ability's core functionality. It receives
 * optional input data and returns either a result or `WP_Error` on failure.
 *
 *     function my_plugin_analyze_text( string $input ): string|WP_Error {
 *         $score = My_Plugin::perform_sentiment_analysis( $input );
 *         if ( is_wp_error( $score ) ) {
 *             return $score;
 *         }
 *         return My_Plugin::interpret_sentiment_score( $score );
 *     }
 *
 * #### Permission Callback
 *
 * The permission callback determines whether the ability can be executed.
 * It receives the same input as the execute callback and must return a
 * boolean or `WP_Error`. Common use cases include checking user capabilities,
 * validating API keys, or verifying system state:
 *
 *     function my_plugin_can_analyze_text( string $input ): bool|WP_Error {
 *         return current_user_can( 'edit_posts' );
 *     }
 *
 * ### REST API Integration
 *
 * Abilities can be exposed through the REST API by setting `show_in_rest`
 * to `true` in the meta configuration:
 *
 *     'meta' => array(
 *         'show_in_rest' => true,
 *     ),
 *
 * This allows abilities to be invoked via HTTP requests to the WordPress REST API.
