Title: Npcink Abilities Toolkit Author: Npcink Published: June 5, 2026 Last modified: June 6, 2026 --- Search plugins ![](https://ps.w.org/npcink-abilities-toolkit/assets/banner-772x250.png?rev=3563029) ![](https://ps.w.org/npcink-abilities-toolkit/assets/icon-256x256.png?rev=3561889) # Npcink Abilities Toolkit By [Npcink](https://profiles.wordpress.org/muze233/) [Download](https://downloads.wordpress.org/plugin/npcink-abilities-toolkit.0.5.0.zip) * [Details](https://wordpress.org/plugins/npcink-abilities-toolkit/#description) * [Reviews](https://wordpress.org/plugins/npcink-abilities-toolkit/#reviews) * [Development](https://wordpress.org/plugins/npcink-abilities-toolkit/#developers) [Support](https://wordpress.org/support/plugin/npcink-abilities-toolkit/) ## Description Npcink Abilities Toolkit provides a standalone toolkit for plugin authors who want to expose safe, agent-callable abilities through the WordPress Abilities API. The plugin owns ability registration helpers, category helpers, schema normalization, annotation normalization, and optional canonical projection for Npcink AI when Npcink AI is installed. It can be used by any WordPress plugin or client that consumes the WordPress Abilities API. Npcink AI is one optional consumer, not the owner of this plugin. It does not own model routing, cloud execution, billing, quota, workflow runtime, MCP governance, or final write approval/governance. Read-only host composition recipe metadata may document how hosts can compose abilities, but those records do not run queues, schedule jobs, execute workflows, or create a second registry. Host composition recipe metadata is available through read-only helpers and Abilities API discovery abilities for hosts that need catalog discovery without execution ownership. ### External Services and Remote Requests This plugin does not automatically contact Npcink AI, model providers, analytics services, tracking services, or cloud services. Some abilities can prepare request payloads for a separate host or cloud add-on, but this plugin does not send those payloads to an external service by itself. The `npcink-abilities-toolkit/upload-media-from-url` ability can download a media file from a URL provided by an authenticated caller when an approved host runtime commits that ability. In that case WordPress sends an HTTP request to the caller- provided URL in order to fetch the media file for the local media library. The remote endpoint is chosen by the caller, not by this plugin. ### Requirements * WordPress 7.0 or later. This release intentionally targets the WordPress Abilities API baseline available in WordPress 7.0+. * PHP 8.0 or later. ### Public API * `npcink_abilities_toolkit_register_category( $category_id, $args )` * `npcink_abilities_toolkit_register_readonly( $ability_id, $definition )` * `npcink_abilities_toolkit_register_write_proposal( $ability_id, $definition )` * `npcink_abilities_toolkit_normalize_schema( $schema, $default_type )` * `npcink_abilities_toolkit_normalize_annotations( $annotations, $risk_level )` * `npcink_abilities_toolkit_get_registered()` * `npcink_abilities_toolkit_get_workflow_definitions()` * `npcink_abilities_toolkit_get_workflow_definition( $recipe_id )` ### Admin Page After activation with a Npcink AI host plugin, open Npcink AI -> Abilities in wp- admin. When this standalone package is installed without a Npcink AI host menu, open Tools -> Abilities API Packages instead. The page verifies Abilities API availability, shows the registered ability catalog, provides copyable REST endpoint values for host/client setup, and can run two official read-only checks: site info and bounded redacted diagnostics summary. It is a connection and discovery surface; it does not run showcase workflows, model calls, write abilities, or demo abilities. ### Built-In Abilities The plugin includes migrated low-risk WordPress read abilities, deterministic comment helpers, and host-governed WordPress write/destructive abilities using canonical` npcink-abilities-toolkit/*` ids. It also includes `npcink-abilities-toolkit/wp-diagnostics-summary`, a redacted WordPress- only diagnostics summary for Abilities API clients. This summary intentionally omits Npcink AI settings, MCP settings, API keys, database names, table prefixes, filesystem paths, error logs, and external HTTP probes. It also includes `npcink-abilities-toolkit/search-posts` and `npcink-abilities-toolkit/ search-post-meta`, bounded local WordPress search helpers for keyword and explicit post-meta discovery. These are read-only helpers and do not call external search indexes or mutate content. It also includes `npcink-abilities-toolkit/list-workflow-recipes` and `npcink-abilities- toolkit/get-workflow-recipe`, read-only host composition recipe metadata discovery abilities. These expose metadata only and do not execute workflow runtime behavior. Core governance handoff docs include a catalog snapshot, permission matrix, and schema boundary audit for hosts that consume this plugin through `npcink-ai-core`. ### Developer Verification When the plugin is installed in a local WordPress site, run: ``` WP_PATH=/path/to/wordpress composer smoke:wp ``` For isolated bounded-chain performance validation, run: ``` composer perf:smoke ``` ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Npcink Abilities Toolkit” is open source software.
