Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00134 | $0.07739 |
| Opus 5 | $0.00067 | $0.03870 |
| Sonnet 5 | $0.00027 | $0.01548 |
| Haiku 4.5 | $0.00013 | $0.00774 |
Grade A, and why
app-tone-manner 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 9d 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.

App Tone & Manner Design Skill
version: 1.0.0
8名のエージェントがディスカッション形式でアプリのトーン&マナーを設計するスキル。 ブランド基盤（Phase 1）→ ビジュアル言語化（Phase 2）→ トーン・オブ・ボイス（Phase 3）の3フェーズで進行し、 各フェーズの Gate を identity-critic が運営する。
ワークフロー概要
Step 1: ヒアリング（必須/任意の情報収集 + ペルソナ自動検索）
Step 2: チーム作成・エージェント起動
Step 3: ディスカッション型ラウンド進行
Phase 1: ブランド基盤設計（並列） → Gate 1
Phase 2: ビジュアル言語化（並列） → Gate 2
Phase 3: トーン・オブ・ボイス → Gate 3（Devil's Advocate）
Step 4: ファイル書き込み検証
Step 5: Pencil 出力生成
Step 6: 統合レポート作成（TONE_MANNER_REPORT.md）
Step 7: ユーザーへの最終報告
Step 8: クリーンアップ（全エージェントシャットダウン）

Step 1: ヒアリング
必須情報（欠けたら質問）
| 項目 | 内容 |
|---|---|
| アプリ/サービス名 | プロダクトの名前 |
| アプリ概要 | 何をするアプリか（1〜3文） |
| ターゲットユーザー | 年齢層・性別・ライフスタイル・利用シーン |
| 競合/参考サービス | 3〜5個（URL または名前） |
任意情報（あれば精度向上）
| 項目 | 内容 |
|---|---|
| 好みのテイスト | 「ミニマル」「温かみのある」「高級感」等の方向性 |
| NGな色・スタイル | 絶対に避けたい要素 |
| 既存ブランドガイドライン | リブランディングの場合 |
| 調査設定 | 「途中確認あり（推奨）」「一気に最後まで」「重要な発見があれば都度」 |
ペルソナの自動検索
ヒアリング完了後、以下のパスを Glob で検索してペルソナデータを取得する:
docs/personas/*.md
.claude/persona-creation/*/personas/*.md
見つかった場合: 全エージェントの起動プロンプトにペルソナ情報を組み込む。 見つからない場合: 「persona-creation スキルで先にペルソナを作成することを推奨しますが、ヒアリング情報で代替可能です」とユーザーに案内。
What ships with it
4 files 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.
- 9d ago First seen · 590 lines · 134 tokens per session scan A 4d231f844f28
app-tone-manner is a skill published in the GitHub repository sean-sunagaku/claude-code-plugin (36 stars, last pushed 1mo ago), licensed MIT. It adds 134 tokens to every session and 7,739 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
