i18n

i18n is a skill for Claude Code from helderberto/agent-skills. It costs 87 tokens per session (496 once invoked), scanned A, original, MIT.

A check of an application's translation coverage and user-facing text. Internationalization, often called i18n, prepares software to support multiple languages and regions.

In plain words
What is it for?
Use it in frontend projects with a translation library to locate hardcoded interface text, compare locale files, and report missing translations.
Why use it?
It finds visible text that was left untranslated and translation keys missing from some language files.

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 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 3d 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

i18n Audit

Detection

Read package.json for i18n library:

  • react-i18next / i18next
  • next-intl
  • vue-i18n
  • react-intl (FormatJS)

Read locale files to understand key structure (e.g. src/locales/en.json).

Workflow

  1. Detect i18n library and locale file locations
  2. Search JSX/TSX/Vue files for hardcoded user-facing strings (see patterns.md):
    • String literals in JSX: <p>Hello world</p>
    • String props: placeholder="Search...", label="Submit"
    • aria-label="Close menu"
  3. Compare locale files — find missing keys between locales
  4. Report findings

Output format

Hardcoded strings (file:line):

src/components/Header.tsx:12  "Welcome back"  → suggest key: header.welcomeBack
src/components/Form.tsx:34    placeholder="Search..."  → suggest key: form.searchPlaceholder

Missing translations (key present in base locale but absent in others):

Key: dashboard.emptyState  missing in: pt-BR, es
Key: errors.networkTimeout  missing in: pt-BR

Rules

  • Only flag user-visible strings (skip internal IDs, CSS classes, URLs, enum values)
  • Suggest translation key names in camelCase matching project convention
  • Never auto-modify locale files — report only

Error Handling

  • If no i18n library detected → report project may not use i18n; still list any hardcoded strings found
  • If no locale files found → skip missing-key comparison; only report hardcoded strings
  • If locale files are not JSON (e.g. .po, .yaml) → read them anyway and adapt key comparison logic
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
