i18n-frontend-implementer

i18n-frontend-implementer is a skill for Claude Code, Codex from patricio0312rev/skillset. It costs 63 tokens per session (366 once invoked), scanned A, a copy of i18n-frontend-implementer, MIT.

A frontend internationalization setup for displaying an application in multiple languages. It organizes translations and formats dates, numbers, currencies, and plural words according to the selected language.

In plain words
What is it for?
Use it to add translation dictionaries, language switching, plural-aware messages, localized dates and numbers, currency formatting, and RTL language support.
Why use it?
It prevents user-facing text and locale-specific formatting from being scattered through application code. It also provides a structured way to switch languages and support languages written right to left.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

i18n-frontend-implementer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

i18n Frontend Implementer

Implement internationalization with next-intl, react-i18next, or similar libraries.

Core Setup

1. Install: npm install next-intl or react-i18next 2. Create dictionaries: locales/en.json, locales/es.json 3. Provider setup: Wrap app with IntlProvider 4. Translation keys: Hierarchical namespace structure 5. Formatters: Date, number, currency formatting 6. Language switcher: Dropdown or flags UI

Translation Structure

{
  "common": { "nav": { "home": "Home", "about": "About" } },
  "auth": { "login": "Sign In", "logout": "Sign Out" },
  "errors": { "required": "{field} is required" }
}

Usage Examples

const t = useTranslations('common');
<h1>{t('nav.home')}</h1>

// With plurals
t('items', { count: 5 }) // "5 items"

// With formatting
<p>{formatDate(date, { dateStyle: 'long' })}</p>

Best Practices

Use namespaces for organization, extract all text to translations, handle plurals properly, format dates/numbers per locale, provide language switcher, support RTL languages, lazy-load translations.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
