WordPress 6.9 introduces the Abilities API, a unified functional interface that enables plugins, themes, and external tools to discover and execute WordPress capabilities programmatically. The API provides a central registry with machine-readable schemas, built-in validation, and permission controls. Developers can register abilities using wp_register_ability() with input/output schemas, making functionality accessible across REST endpoints, blocks, and AI agents. The implementation demonstrates converting a plugin's core function into a reusable ability that works seamlessly in admin pages, REST APIs, and the Block Editor without duplicating code.
