i18n-check

i18n-check is a skill for Claude Code from berkcangumusisik/claude-code-practices. It costs 19 tokens per session (344 once invoked), scanned A, original, MIT.

A code review helper that finds user-facing text written directly in source code and turns it into translation keys. Translation keys let an app show the same message in different languages.

In plain words
What is it for?
Use it to scan frontend files, identify text that users can see, create matching keys in a locale file, replace the original text with translation calls, and report what was changed or skipped.
Why use it?
It removes the manual search for text that was missed during internationalization. It also helps avoid inconsistent translation files and source code replacements.

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

i18n-check 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 9d 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.

What it actually says

Internationalization Check

Target: $1 (or src/ if not specified)

  1. Detect i18n library:
cat package.json | grep -E '"i18next"|"react-intl"|"vue-i18n"|"@angular/localize"|"next-intl"'
ls src/locales/ src/i18n/ public/locales/ 2>/dev/null | head -10
  1. Find hardcoded user-visible strings (not variable names, not URLs):
grep -rn '"[A-Z][a-z ]\+"\|'"'"'[A-Z][a-z ]\+'"'" ${1:-src/} --include="*.tsx" --include="*.jsx" --include="*.vue" | grep -v "className\|import\|export\|test\|spec" | head -30
  1. For each hardcoded string:

    • Is it user-visible? (skip internal error codes, class names)
    • Generate a translation key: page.section.description
    • Show the replacement code using the project's i18n function
  2. Update the locale file (en.json or equivalent) with new keys.

  3. Replace hardcoded strings in source with i18n function calls.

  4. Report: N strings found, N replaced, N skipped (non-user-visible).

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.
