What it does

I18n Localization is an agent skill from xenitV1/Antigravity-Workflows. Internationalization and localization patterns. Detecting hardcoded strings, managing translations, locale files, RTL support.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/i18n_checker.py`).

It sits in Frontend & Design, covering Internationalization. The licence is MIT.

When your agent uses it

  • Tasks that involve Internationalization

Example prompts

  • “/i18n-localization”

Requirements

  • Python 3
  • Pre-approved tools (allowed-tools): Read, Glob, Grep

8 steps, taken from the step headings in SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit f0a1fa7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

I18n Localization loads about 758 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 209 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~758

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

i18n & Localization

Internationalization (i18n) and Localization (L10n) best practices.


1. Core Concepts

TermMeaning
i18nInternationalization - making app translatable
L10nLocalization - actual translations
LocaleLanguage + Region (en-US, tr-TR)
RTLRight-to-left languages (Arabic, Hebrew)

2. When to Use i18n

Project Typei18n Needed?
Public web app✅ Yes
SaaS product✅ Yes
Internal tool⚠️ Maybe
Single-region app⚠️ Consider future
Personal project❌ Optional

3. Implementation Patterns

React (react-i18next)
tsx
import { useTranslation } from 'react-i18next';

function Welcome() {
  const { t } = useTranslation();
  return <h1>{t('welcome.title')}</h1>;
}
Next.js (next-intl)
tsx
import { useTranslations } from 'next-intl';

export default function Page() {
  const t = useTranslations('Home');
  return <h1>{t('title')}</h1>;
}
Python (gettext)
python
from gettext import gettext as _

print(_("Welcome to our app"))

└── ar/          # RTL
    └── ...

5. Best Practices

DO ✅
  • Use translation keys, not raw text
  • Namespace translations by feature
  • Support pluralization
  • Handle date/number formats per locale
  • Plan for RTL from the start
  • Use ICU message format for complex strings
DON'T ❌
  • Hardcode strings in components
  • Concatenate translated strings
  • Assume text length (German is 30% longer)
  • Forget about RTL layout
  • Mix languages in same file

6. Common Issues

IssueSolution
Missing translationFallback to default language
Hardcoded stringsUse linter/checker script
Date formatUse Intl.DateTimeFormat
Number formatUse Intl.NumberFormat
PluralizationUse ICU message format

7. RTL Support

css
/* CSS Logical Properties */
.container {
  margin-inline-start: 1rem;  /* Not margin-left */
  padding-inline-end: 1rem;   /* Not padding-right */
}

[dir="rtl"] .icon {
  transform: scaleX(-1);
}

8. Checklist

Before shipping:

  • All user-facing strings use translation keys
  • Locale files exist for all supported languages
  • Date/number formatting uses Intl API
  • RTL layout tested (if applicable)
  • Fallback language configured
  • No hardcoded strings in components
