Build and debug custom WordPress REST API endpoints with schema and permission guardrails

Uses the WordPress wp-rest-api skill to help an agent design, register, validate, and troubleshoot custom REST routes without skipping schema, auth, or permission_callback details. This is for agent-led endpoint work in plugins, themes, or core-adjacent codebases, not for browsing the WordPress REST API as a product catalog.

Prerequisites

WordPress codebase access, PHP, and optional WP-CLI for verification
