Templates

• Custom Post Type - CPT registration class locking in project conventions (i18n labels, activation-only rewrite flush, show_in_rest). No dedicated command — use this template directly when a task involves registering a post type.

Use this skill when working on:

• PHP Files: Writing or reviewing .php files
• Database Operations: Custom queries, table creation, migrations

• REST API: Creating custom endpoints, authentication
• Admin Interface: Settings pages, meta boxes, admin menus
• Custom Post Types/Taxonomies: Registering and managing
• Hooks: Creating actions and filters
• Cron Jobs: Scheduled tasks
• WP-CLI: Custom commands
• Security: Nonce verification, input sanitization, output escaping
• Performance: Query optimization, caching strategies
