Make WordPress code translation-ready. Use when writing any user-facing string, adding text domains, fixing untranslated output, or preparing a plugin/theme for localization. Enforces the i18n escaping matrix, translators comments, numbered placeholders, and text-domain rules.

We split this skill into the rules it gives an agent

6 rules. 0 are common, 3 are distinctive, and 3 are very specific to this project.

  • 0

    Common

    Most of the 3 edited versions we read keep these.

  • 3

    Distinctive

    This author's own choices. Worth a look.

  • 3

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Every user-facing string passes through a translation function.

    line 8
  2. Very specific:

    Never raw __( ) or _e() inside HTML — always the escaping variants.

    line 24
  3. Very specific:

    Translators comment: must immediately precede the gettext call and start with translators: — explains every placeholder

    line 32
  4. Distinctive:

    Don't translate markup — translate the text, escape at echo

    line 36
  5. Distinctive:

    Avoid near-duplicate strings (same wording, same punctuation)

    line 37
  6. Very specific:

    Use wp.i18n (wp_set_script_translations( 'handle', 'domain' ) after enqueue): wp.i18n.__(), sprintf(), _n() — never hardcoded UI strings in …

    line 49

“Common” is measured: kept by at least 6 in 10 of the 3 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

i18n — Translation-Ready WordPress Code

Every user-facing string passes through a translation function. No exceptions. Text domain = plugin/theme slug with dashes, passed as the LAST argument, never via variable/constant.

Function matrix

ContextFunction
Echo textesc_html_e( 'Text', 'domain' )
Return textesc_html__( 'Text', 'domain' )
Attributeesc_attr_e() / esc_attr__()
Context (noun vs verb)_x( 'Post', 'noun', 'domain' ) / esc_html_x()
Plural_n( 'item', 'items', $count, 'domain' )
Plural + context_nx()
Numbers/datesnumber_format_i18n(), date_i18n()

Never raw __( ) or _e() inside HTML — always the escaping variants.

String rules

  • No interpolation — use placeholders: printf( /* translators: %s: Name */ esc_html__( 'Welcome, %s', 'domain' ), $name );
  • Multiple placeholders: numbered %1$s, %2$d in single quotes (double quotes would interpolate $s)
  • Translators comment must immediately precede the gettext call and start with translators: — explains every placeholder
  • Full sentences, no leading/trailing whitespace, no URLs inside strings, no empty strings, no \r
  • Don't translate markup — translate the text, escape at echo
  • Avoid near-duplicate strings (same wording, same punctuation)

Loading

  • Themes: load_theme_textdomain( 'domain', get_template_directory() . '/languages' ) in the after_setup_theme setup function
  • Plugins: load_plugin_textdomain( 'domain', false, dirname( plugin_basename( __FILE__ ) ) . '/languages' ) on init
  • Header: Text Domain: domain + Domain Path: /languages in both

JS strings

  • Use wp.i18n (wp_set_script_translations( 'handle', 'domain' ) after enqueue): wp.i18n.__(), sprintf(), _n() — never hardcoded UI strings in JS for user-facing text

Audit

Grep for: __( / _e( without text domain, raw quotes around user-facing text in templates, interpolated $var inside __('... $var ...'), missing translators comments on placeholders. The WPCS WordPress.WP.I18n sniff catches most — run phpcs.

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
