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

Internationalizing Websites scanned grade A with 1 finding 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 12d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/i18n-add-languages.mjs, scripts/i18n-add-schema.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Internationalizing Websites

Complete workflow for adding multi-language support to Next.js websites with SEO best practices.

When to use this Skill

  • Adding new language versions to existing website
  • Setting up i18n (internationalization) for new website
  • Configuring SEO for multiple languages
  • User mentions: "add language", "translation", "localization", "hreflang", "multi-language"

Supported Languages

Common target markets:

  • 🇺🇸 English (en) - Global market
  • 🇯🇵 Japanese (ja) - Asian market
  • 🇨🇳 Chinese (zh) - Chinese market

Extended support available for:

  • Korean (ko), Portuguese (pt), Spanish (es), French (fr), German (de)
  • Arabic (ar), Vietnamese (vi), Hindi (hi), Indonesian (id), Thai (th)
  • Traditional Chinese (zh-hk), Italian (it), Russian (ru)

Internationalization Workflow

Copy this checklist and track your progress:

i18n Progress:
- [ ] Step 1: Prepare base language files
- [ ] Step 2: Add new language files
- [ ] Step 3: Update configuration files
- [ ] Step 4: Add translations
- [ ] Step 5: Configure SEO elements
- [ ] Step 6: Validate and test

Step 1: Prepare base language files

Ensure English (en.json) files exist as templates:

Required directories:

  • i18n/messages/en.json - Main translations
  • i18n/pages/landing/en.json - Landing page translations

Verify structure:

# Check if base files exist
ls i18n/messages/en.json
ls i18n/pages/landing/en.json

If missing, create them with complete translation keys for your website.

Step 2: Add new language files

Run the language addition script:

node scripts/i18n-add-languages.mjs

What this script does:

  • Copies en.json to all target language files
  • Updates i18n/locale.ts with new locales
  • Updates i18n/request.ts with language mappings
  • Updates public/sitemap.xml with new language URLs

Script configuration (in i18n-add-languages.mjs):

  • languages array - List of languages to add
  • languageNames object - Language display names
  • targetDirs array - Directories containing translation files

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
