i18n-setup

i18n-setup is a skill for Claude Code from hamzaPixl/pixl-ai. It costs 47 tokens per session (1,027 once invoked), scanned A, original, MIT.

A workflow for adding internationalization, meaning support for multiple languages, to a Next.js application. It covers English, French, and Dutch translation setup, extraction, validation, and integration.

In plain words
What is it for?
Use it to add or review multilingual support in a Next.js app and migrate existing content into the translation system.
Why use it?
It removes much of the manual work involved in finding user-facing text and connecting translated content to the application.

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-setup 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Setup

Read config.json in this skill directory (if it exists):

  • locales — target locale list; default ["en", "fr", "nl"]
  • default_locale — fallback locale; default "en"
  • library — i18n library preference; default "next-intl"

If the argument provides locales (e.g. /i18n-setup en,fr,de), override the config defaults. If neither argument nor config provides locales, use AskUserQuestion: "Which locales should this project support? (comma-separated BCP-47 codes, e.g. en,fr,nl)"

Overview

Adds internationalization (i18n) to a Next.js application supporting EN/FR/NL. Covers infrastructure setup, translation extraction, component integration, and optional CMS/MDX content migration.

Required References

Before starting, read references/frontend/i18n-conventions.md for locale file structure, key naming, and pluralization patterns.

Step 1: Discovery

  1. Analyze existing Next.js configuration (App Router vs Pages Router)
  2. Identify all user-facing strings in the codebase
  3. Check for existing i18n setup or library
  4. Determine content sources (hardcoded, CMS, MDX)
  5. Count translatable strings for scope estimation

Step 2: Infrastructure

  1. Install and configure i18n library (next-intl or similar)
  2. Set up locale routing (/en/..., /fr/..., /nl/...)
  3. Create translation file structure (messages/en.json, messages/fr.json, messages/nl.json)
  4. Add locale detection and switching
  5. Configure middleware for locale routing

Step 3: Translation Extraction (Parallel — 3 Agents)

Spawn 3 Explore agents to scan the codebase in parallel:

  1. Extract all hardcoded strings from components
  2. Generate translation keys following a consistent naming convention
  3. Create initial translation files with English as source

Step 4: Translation Quality Pass

After generating English source strings, translate to each target locale with these mandatory rules:

French (fr)

  • All diacritics are required — never omit accents: é è ê ë à â ç ù û ô î ï œ æ
  • Common mistakes to avoid:
    • "évenement" → événement, "parametre" → paramètre, "creer" → créer
    • "deja" → déjà, "a" (preposition) vs à, "ou" (or) vs où (where)
    • Past participles: "termine" → terminé, "supprime" → supprimé
  • Sentence structure: French uses spaces before :, !, ?, ; (thin non-breaking space \u202F preferred)
  • Use « guillemets » for quotes, not "English quotes"

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.
