WordPress Development AI Skill Guide (Claude)

Overview & Engine Architecture

WordPress serves content via themes + plugins on PHP + MySQL. Behavior extends through actions/filters, custom post types, and the REST API. WP-CLI drives installs, search-replace, and cron without the browser. Agents sanitize on input / escape on output, use $wpdb->prepare or WP APIs, require current_user_can + nonces (nonces alone are not auth), always set REST permission_callback, and never commit wp-config.php secrets or edit core files.
