I18nstack

i18nstack: the i18n toolkit for AI coding agents

Three CLI tools + 46 language-specific translation skills. Route any i18n task to the right piece:

| Task | Use | |------|-----| | Convert a localization file to another format | i18n-convert CLI (see i18n-convert skill) | | Generate pseudo-translations to test an i18n setup | i18n-pseudo CLI (see i18n-pseudo skill) | | Check translation files for missing keys, placeholder drift, plural errors | i18n-validate CLI (see i18n-validate skill) | | Translate text into language XX with native-quality rules | localize-XX skill (46 languages, e.g. localize-ja, localize-de) | | Wrap hardcoded strings in code with i18n functions | i18n-wrap skill | | Audit existing i18n wrapping for quality issues | i18n-review skill | | Validate AND fix all findings until green | i18n-validate-workflow skill | | Safe format conversion with data-loss checks | i18n-convert-workflow skill | | Pseudo-locale QA sweep with fix-up | i18n-pseudo-workflow skill |

Setup check (run BEFORE using any CLI)

for t in i18n-convert i18n-pseudo i18n-validate; do command -v $t >/dev/null || echo "MISSING: $t"; done

If anything is missing:

npm install -g @i18n-agent/i18n-convert @i18n-agent/i18n-pseudo @i18n-agent/i18n-validate

Or run full agent wiring: npx skills add i18n-agent/i18nstack -g -y --skill '*' then ./setup.

Recommended workflow (new locale end to end)

1. Convert the source file into the target project's format if needed:

i18n-convert en.json --to android-xml -o strings.xml

1. Pseudo-translate before paying for real translations to catch hardcoded

strings, overflow, and encoding bugs: i18n-pseudo en.json --preset layout -o pseudo/

1. Translate using the matching localize-XX skill — it enforces

native-writer rules (formality, particles, plurals, script conventions).

1. Validate the result before shipping:

i18n-validate ./locales --strict

Each is a standalone skill (localize-ja, localize-de, …) distilled from production translation prompts — invoke the one matching your target language.
