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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00057 | $0.00570 |
| Opus 5 | $0.00028 | $0.00285 |
| Sonnet 5 | $0.00011 | $0.00114 |
| Haiku 4.5 | $0.00006 | $0.00057 |
Grade A, and why
l10n-guideline 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 4d 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
L10N Guideline
When to use
- 逐語訳を避け自然な日本語に意訳するとき
- UI 要素（ボタン、メニュー、ツールチップ等）の訳語を決めるとき
- です・ます調・英数記号の全角半角を確認するとき
l10n.sourceCommit等の front-matter を確認するとき
Quick checklist
- 英語直訳特有の言い回しを避け、余分な主語を削除
- です・ます調で統一
- 「Web」→「ウェブ」
- UI コンテクスト別表現（体言止め、動詞末尾等）を適用
-
(前は半角空白、)後は半角空白 - front-matter の
l10n.sourceCommitが英語版コミットハッシュ - 用語集
titleはEnglish (日本語) -
{{GlossarySidebar}}を残さない - 原文の語句を省略せず、辞書的意味がずれる訳を避ける
- 英日併記は初出のみ。括弧内の英語展開も訳す
- 原文のイタリック等の強調を維持する
- Wikipedia リンクは概念が一致する言語版を選ぶ
Workflow
- 原文の意図を把握し、逐語訳でない訳案を作成
- UI 要素の種類を特定し、コンテクスト別ルールを適用
- references/l10n-guideline.md で詳細を確認
- レビュー慣行は harvest-review-findings の conventions と併用
- 表記・用語は editorial-guideline / mozilla-l10n-glossary と併用

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.
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.
