name: i18nstack description: | Complete i18n/localization toolkit for Claude Code. Use when doing ANY internationalization work: converting localization files between 32 formats (i18n-convert), pseudo-translating files to QA an i18n implementation (i18n-pseudo), validating translation files for missing keys / placeholder drift / plural errors (i18n-validate), or translating UI strings, marketing copy, and docs into 46 languages with native-quality rules (localize-*). allowed-tools:
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 command |
| Audit existing i18n wrapping for quality issues | /i18n-review command |
| Validate AND fix all findings until green | /i18n-validate command |
| Safe format conversion with data-loss checks | /i18n-convert command |
| Pseudo-locale QA sweep with fix-up | /i18n-pseudo command |
for t in i18n-convert i18n-pseudo i18n-validate; do command -v $t >/dev/null || echo "MISSING: $t"; done
If anything is missing, run the stack's setup: ~/.claude/skills/i18nstack/setup
(or npm install -g @i18n-agent/<tool>).

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

i18nstack turns Claude Code into a full localization team: format engineer, QA tester, release gate, and 46 native-quality translators.
Three battle-tested CLI tools, five workflow slash commands, and 46 language-specific translation skills for Claude Code, installed with one command.
git clone --depth 1 https://github.com/i18n-agent/i18nstack.git ~/.claude/skills/i18nstack && ~/.claude/skills/i18nstack/setup
That's it. The setup script installs the CLI tools (npm, with Homebrew fallback) and registers every skill with Claude Code.
| Tool | Role | What it does |
|---|---|---|
i18n-convert |
Format engineer | Convert localization files between 32 formats: JSON, i18next, Flutter ARB, Android XML, iOS .strings/String Catalog, XLIFF, PO, YAML, RESX, CSV, Excel, and more. Warns before lossy conversions. |
i18n-pseudo |
QA tester | Pseudo-translate locale files to expose hardcoded strings, text overflow, encoding bugs, and RTL breakage before you pay for real translations. 7 strategies, 5 presets. |
i18n-validate |
Release gate | Validate translation files for missing keys, placeholder drift, malformed plurals, and untranslated values. CI-ready with JUnit/JSON output and meaningful exit codes. |
| Command | What it does |
|---|---|
/i18n-wrap [path] [--framework=...] |
Scan code for hardcoded user-facing strings and wrap them with the right i18n function (next-intl, react-i18next, vue-i18n, angular, svelte, python, ruby, flutter, ios, android). Updates locale files and validates. |
/i18n-review [path] [--framework=...] |
Read-only audit of existing i18n wrapping: over/under-wrapping, split sentences, hardcoded values, quality issues. |
/i18n-validate [path] |
Run validation and FIX every finding — placeholder drift, plural forms, missing keys (translated properly, never English filler) — looping until it passes. |
/i18n-convert <file> --to <format> |
Safe conversion workflow: resolve the format slug, dry-run for data-loss warnings, convert, verify key counts round-trip. |
/i18n-pseudo <files> [--preset=...] |
Generate pseudo locales, wire them into the app as a test locale, and hunt down the hardcoded strings and layout bugs they expose. |
Each localize-XX skill is distilled from production translation prompts and enforces native-writer rules: formality registers, particle selection, plural systems, script conventions, and false-friend avoidance.
