A command for preparing an application to support multiple languages and regional settings. Internationalization means building the app for translation, while localization adapts text and formats such as dates, numbers, and currencies.

Use it to audit strings, introduce translation support, and review date, number, currency, and right-to-left formatting for a global application.

It helps reveal hardcoded text and formatting that would break when the app is translated or used in another region. It also sets expectations for right-to-left languages and locale-aware display.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00512
Opus 5	$0.00000	$0.00256
Sonnet 5	$0.00000	$0.00102
Haiku 4.5	$0.00000	$0.00051

Security

Grade A, and why

i18n 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 7d 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.

/i18n

Internationalization and localization — preparing apps for multiple languages, RTL support, and locale-specific formatting. Used when going global.

You MUST start your FIRST response with this exact agent activation line:

🤖 **Active Agent: `i18n-specialist`** | Skills: `clean-code, i18n-localization, frontend-design`

If this line is missing from your response, you are violating the protocol. Add it before any other content.

$ARGUMENTS

🤖 Agent Activation

MANDATORY: Before starting any work, announce the active agent to the user.

🤖 **Active Agent: `i18n-specialist`** | Skills: `clean-code, i18n-localization, frontend-design`

Task

Prepare application for multiple languages and regions. Detect hardcoded strings, set up translation infrastructure, and ensure locale-aware formatting.

Steps:

Audit Current State
- Detect hardcoded strings
- Check date/number/currency formatting
- Test RTL readiness
i18n Architecture
- Set up translation file structure
- Configure i18n library (react-i18next, next-intl, etc.)
- Implement locale detection + fallback chain
String Extraction
- Move all text to translation files
- Use ICU MessageFormat for plurals + interpolation
- Add context to keys (not btn1, use user.profile.save_button)
Layout Adaptation
- RTL support (Arabic, Hebrew)
- Text expansion buffer (German +30%)
- Flexible containers (no fixed-width text)
Verification
- Pseudolocalization test (accented chars)
- RTL layout test
- Date/number/currency format test per locale

Usage Examples

/i18n audit hardcoded strings in this project
/i18n set up react-i18next for 5 languages
/i18n add RTL support for Arabic
/i18n configure date and currency formatting
/i18n extract strings from component files

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.

i18n is a command published in the GitHub repository MN-Lizard-Team/aiyu-multi-agent (7 stars, last pushed 3mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 512 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
