Rule Content
# WordPress Development Rules ## Code Style - PHP 7.4+ with `declare(strict_types=1);` - WordPress PHP Coding Standards - OOP where it improves modularity - Lowercase hyphenated directories: `wp-content/themes/my-theme` - Minimal comments—only for non-obvious logic ## Core Principles - Never modify core files—use hooks exclusively - Use core functions before custom solutions - Child themes for all customizations - `$wpdb->prepare()` for all dynamic queries - Nonce verification on all form submissions - Escape output, sanitize input—no exceptions ## Database - `$wpdb` abstraction layer only - `dbDelta()` for schema changes - Transients API for caching ## Assets & AJAX - `wp_enqueue_script()` / `wp_enqueue_style()` exclusively - REST API preferred over `admin-ajax.php` ## Output Expectations - Working code, not explanations - Production-ready security practices baked in - No boilerplate comments or placeholder text - If something is unclear, ask—don't assume
