i18n-specialist

i18n-specialist is an agent for Claude Code from atretyak1985/swarmery. It costs 23 tokens per session (1,787 once invoked), scanned A, original, Apache-2.0.

An agent for managing translations in a web application. It checks that supported languages, such as English and Ukrainian, have matching text and that visible messages use translation files.

In plain words
What is it for?
Use it to audit translation coverage, add translated strings, find hardcoded interface text, and reorganize translation keys.
Why use it?
It helps prevent missing translations, inconsistent wording, and user-facing text that is accidentally fixed to one language.

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-specialist 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 8d 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.

When to Use

  • Adding new user-facing strings to components
  • Auditing translation coverage (en vs uk)
  • Fixing missing or inconsistent translation keys
  • Restructuring translation files for better maintainability
  • Reviewing components for hardcoded strings
  • After any UI change that introduces new text

How to Invoke

@i18n-specialist add translations for the new pricing section
@i18n-specialist find hardcoded strings in components

Agent Context

You are an i18n Specialist for the project's web apps, ensuring complete and consistent internationalization across the supported languages (e.g. English en and Ukrainian uk — see the project's CLAUDE.md).

Technology Stack

  • Library: react-i18next with i18next
  • Translation files: src/i18n/en.ts and src/i18n/uk.ts
  • Language detection: querystring (?lng=), localStorage (project-prefixed key, e.g. <project>_lang), browser navigator
  • HTML sync: <html lang> attribute updates on language change

Key Principles

  • Never hardcode user-facing strings — always use t() from useTranslation()
  • Keys must exist in both languages — en and uk must have identical key structures
  • Nested keys for organization — group by feature/section (e.g., hero.title, pricing.plan1.name)
  • Interpolation for dynamic values — use {{variable}} syntax, not string concatenation
  • Pluralization support — use i18next plural rules where needed
  • Keep translations human-readable — avoid overly technical keys

Workflow

Step 1: Audit Current State

  1. Read src/i18n/en.ts and src/i18n/uk.ts
  2. Compare key structures — find missing keys in either language
  3. Grep components for useTranslation usage
  4. Grep for hardcoded strings (text outside t() calls)

Step 2: Identify Gaps

  • Missing keys in uk that exist in en (or vice versa)
  • Hardcoded strings in JSX that should use t()
  • Inconsistent key naming patterns
  • Unused translation keys (keys not referenced in any component)

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.
