i18n-maintenance is a skill for Claude Code from parisgroup-ai/imersao-ia-setup. It costs 67 tokens per session (3,690 once invoked), scanned A, original, MIT.

A maintenance tool for translation files and language support in multi-language software. It checks whether translation keys and locale files match the code and each other.

In plain words
What is it for?
Use it when adding translated text, checking language coverage, investigating missing-key errors, or reviewing translation files before deployment.
Why use it?
It helps find missing translations, unused entries, and differences between the code and translation files before they cause runtime or release problems.

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-maintenance 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 12d 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.

i18n Maintenance

Overview

Mantém consistência entre arquivos de tradução (i18n) em projetos multi-idioma. Valida estrutura, detecta chaves faltando, encontra traduções não utilizadas, valida sincronização código↔JSON e garante cobertura completa.

Princípio central: O locale en-US é a fonte de verdade para estrutura de chaves. Todos os outros locales devem ter a mesma estrutura.

Diferença desta Skill vs i18n-audit

Skill Foco O que detecta
i18n-maintenance (esta) Arquivos JSON + código Chaves faltando, órfãs, estrutura, código↔JSON mismatch
i18n-audit Código fonte (TSX/TS) Textos hardcoded que deveriam usar t()

Use esta skill quando: Validando arquivos de tradução ou erros de chave faltando Use i18n-audit quando: Procurando texto português hardcoded no código

When to Use

Use quando:

  • Adicionar novas strings de tradução
  • Verificar se todas as chaves estão traduzidas
  • Encontrar traduções órfãs (não utilizadas no código)
  • Erro MISSING_MESSAGE: Could not resolve 'key' (código↔JSON mismatch)
  • Antes de deploy para garantir cobertura completa
  • Após criar novas páginas/componentes com texto

Não use quando:

  • Apenas lendo conteúdo traduzido
  • Trabalhando em código sem strings i18n
  • Procurando texto hardcoded (use i18n-audit)

Checklist de Validação

Execute na ordem:

1. Verificar Estrutura de Chaves (JSON ↔ JSON)

1.1 Extrair todas as chaves do locale de referência:

# Extrair chaves do en-US (fonte de verdade)
jq -r 'paths(scalars) | join(".")' apps/web/src/i18n/messages/en-US.json | sort > /tmp/keys-en-US.txt

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.
