wp-abilities-api

Registering WordPress abilities requires defining a stable id, label, category, and meta. Enabling show_in_rest in your PHP registration ensures the ability is properly exposed via the wp-abilities/v1 REST endpoints.

The best way to coordinate abilities registration is using a centralized PHP approach that defines id, label, category, and meta, then exposes them via REST endpoints for seamless @wordpress/abilities client consumption.
