Block unauthorized users from admin pages, AJAX, REST, and direct PHP file access.

Enable WP_DEBUG tools and inspect notices/errors while developing plugins.

Ship secure plugins with defense-in-depth: caps, nonces, sanitize, escape, prepare.

Stop cross-site request forgery using nonces on forms, links, AJAX, and REST where appropriate.

Prevent SQL injection with $wpdb->prepare and trusted allowlists for SQL identifiers.

Make plugin strings translatable and load text domains correctly.

Use __, _e, esc_html__, _n, and related helpers for i18n-ready plugins.

Make plugins work smoothly with WPML, Polylang, and multilingual content setups.

Keep plugins fast by reducing queries, loading assets conditionally, and caching expensive work.

Use transients and the object cache API to store expensive results temporarily.
