copy-tuner

copy-tuner is a skill for Claude Code, Codex from SonicGarden/copy-tuner-ruby-client. It costs 175 tokens per session (2,185 once invoked), scanned A, original, MIT.

A project-specific tool for finding and managing translation keys, the labels and messages shown in different languages. It determines whether each key belongs in the application’s locale files or in the CopyTuner translation service.

In plain words
What is it for?
Use it when adding, changing, removing, or locating translations, or when working with locales, translation helpers, or the project’s translation configuration.
Why use it?
It prevents developers from editing stale or incorrect translation files and helps keep changes in the system that actually owns each key.

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

copy-tuner 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.

copy_tuner スキル

このプロジェクトの i18n は原則 copy_tuner サーバで管理し、MCP ツールで操作する。 例外として local_first_key_regexp にマッチするキーだけは config/locales/*.yml で管理される。 どちらの管理かを最初に判別する。

キーの管理場所の判別

  1. config/initializers/copy_tuner.rblocal_first_key_regexp を確認する(未設定なら全キー copy_tuner)。
  2. 対象キーから locale を除いた形ja.views.fooviews.foo)がその正規表現にマッチするか見る。
判別 管理場所 操作
マッチする config/locales(copy_tuner と完全分離) config/locales/*.yml を Read / Edit
マッチしない・未設定 copy_tuner MCP ツール経由でのみ探す(下記)

copy_tuner 管理のキーは必ず MCP ツール経由で探すこと。 ローカルの .yml を grep して見つけたつもりになってはならない。

例外(gem 組み込み・設定不要で常に config/locales 管理): Rails 標準の number.format / number.currency.format / number.percentage.format / number.human.format(およびその配下)。 precision 等の非文字列値を含み copy_tuner では正しく扱えないため、gem が常にバイパスする。 これらは config/locales/*.yml を見る・編集すること(アプリ独自の number.gift_amount 等は対象外で通常どおり copy_tuner)。

config/locales 以外の export 済み yml は参照禁止: 環境によっては copy_tuner から export したキャッシュ用の .ymlconfig/locales 配下以外、例: アプリ直下や tmp/db/ などに置かれた export ファイル)が存在することがある。 これらは古いスナップショットであり権威ある情報源ではない。読んで判断材料にしてはならない。 copy_tuner 管理キーは常に MCP ツールで最新を確認する。

config/locales 管理キーの落とし穴:

  • copy_tuner には存在しないので、MCP ツールで探しても見つからない。config/locales を見ること。
  • copy_tuner に登録しても lookup でバイパスされ無効。必ず .yml 側に書く。
  • ja が無ければ未訳(nil)。copy_tuner にフォールバックしない(移行漏れを顕在化させる設計)。
  • prefix 単位の一括移行は別作業。必要なら skills/copy-tuner-to-locales-migrate-prefix/ を使う。

copy_tuner MCP ツール

やりたいこと ツール
キー名(一部)から翻訳を調べる search_key(引数は英語キーワード)
画面テキストからキーを逆引き search_translations
新しいキーを登録する create_i18n_key
既存キーのドラフト訳を更新する update_i18n_key
既存キーの翻訳を更新する(ブラウザ) get_edit_url
使用中ロケールを確認 get_locales

新規キー登録

  1. search_key で関連キーを検索し、既存の命名パターンに合わせる(例: search_key("move_out"))。
  2. ja は必須。他は get_locales で確認し、存在するロケール分を登録する。

既存キーの訳を更新する

update_i18n_key を使う。keytranslations(ロケール・値のペア配列)は両方必須。

制約: ドラフト状態または未発行のキーのみ更新可能。発行済み(published)かどうかを事前に知る手段はなく、API にリクエストしてエラーが返るかどうかで初めてわかる。

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.
