Classic Theme Internationalization and Text Domain

Use this when adding or reviewing translation readiness in a classic PHP theme: text domain headers, PHP strings, plural strings, context, translator comments, local .mo files, and JavaScript translations.

When to Use This Skill

• Creating or reviewing a theme style.css header.
• Adding visible text to templates, functions.php, Customizer controls, menus, widgets, or comments.
• Loading bundled theme translations.
• Fixing WP 6.7+ "translations loaded too early" notices.
• Auditing text domains before release.

Text Domain Header

Set the text domain in style.css.
