WordPress plugin development rules focus on security, compatibility, and clean coding. Never edit WordPress core files; use hooks, shortcodes, and APIs. Validate and sanitize all input, escape all output, and use nonces for forms and AJAX. Check user capabilities before allowing changes. Use unique prefixes or namespaces to avoid function and class conflicts. Follow WordPress coding standards for PHP, JS, and CSS. Load scripts only where needed, and enqueue them properly. Use WordPress APIs for database, options, HTTP requests, and file handling. Keep performance in mind, avoid heavy queries, and support updates with versioning and backward compatibility where possible.
