Implements multi-language support using i18next, gettext, or Intl API with translation workflows and RTL support. Use when building multilingual applications, handling date/currency formatting, or supporting right-to-left languages.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Internationalization (i18n)

Implement multi-language support with proper translation management and formatting.

## i18next Setup (React)

```javascript
import i18n from 'i18next';
import { initReactI18next } from 'react-i18next';
import LanguageDetector from 'i18next-browser-languagedetector';

i18n
  .use(LanguageDetector)
  .use(initReactI18next)
  .init({
    fallbackLng: 'en',
    interpolation: { escapeValue: false },
    resources: {
      en: { translation: { welcome: 'Welcome, {{name}}!' } },
      es: { translation: { welcome: '¡Bienvenido, {{name}}!' } }
    }
  });

// Usage
const { t } = useTranslation();
<h1>{t('welcome', { name: 'John' })}</h1>
```

## Pluralization

```javascript
// Translation file
{
  "items": "{{count}} item",
  "items_plural": "{{count}} items",
  "items_zero": "No items"
}

// Usage
t('items', { count: 0 })  // "No items"
t('items', { count: 1 })  // "1 item"
t('items', { count: 5 })  // "5 items"
```

## Date/Number Formatting

```javascript
// Dates
new Intl.DateTimeFormat('de-DE', {
  dateStyle: 'long',
  timeStyle: 'short'
}).format(new Date());

// Numbers
new Intl.NumberFormat('en-US', {
  style: 'currency',
  currency: 'USD'

How to install

The exact contents, by fingerprint

mdr add secondsky/claude-skills/internationalization-i18n@sha256:2ff14416fa2b401f

The line at the top of this page pins the label git:20260402.75421fa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
