- Works in 3 steps: Triggering Test（発火テスト） → Functional Test（機能テスト） → Performance Test（性能テスト）
- : スキルの実行・呼び出し（それは各スキル自体が行う）

What it does
Skill Creator is an agent skill from yohey-w/multi-agent-shogun. Claude Codeスキル（SKILL.md）の設計・作成・バリデーション・レビュー。 Anthropic公式ガイド(2026-03)準拠。新規スキル作成、既存スキルの改善、 description品質チェック、トリガーテスト設計に使用。 「スキル作って」「スキル設計」「SKILL.md作成」「スキルレビュー」で起動。 Do NOT use for: スキルの実行・呼び出し（それは各スキル自体が行う）。
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Skill authoring. The repository describes itself as: Samurai-inspired multi-agent system for Claude Code. Orchestrate parallel AI tasks via tmux with shogun → karo → ashigaru hierarchy. The licence is MIT.
When your agent uses it
- : スキルの実行・呼び出し（それは各スキル自体が行う）
- Tasks that involve Skill authoring
Example prompts
- “/skill-creator”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit aff8dc8. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml, markdown and bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Skill Creator loads about 1.8k tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 382 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Description設計（最重要 — 発火品質を決める）
descriptionはClaude Codeが「このスキルを使うか否か」を判断する唯一の材料。 本文は発火判定に使われない。1024文字以内。
構造: [What] + [When] + [Negative trigger]
# Good — 具体的、トリガーあり、ネガティブトリガーあり
description: |
Figmaデザインファイルを分析し、開発者向けハンドオフドキュメントを生成。
.figファイルアップロード時、「デザインスペック」「コンポーネント文書」
「デザインからコードへ」と言われた時に起動。
Do NOT use for: 一般的な画像処理やUI設計（interface-designスキルを使え）。
# Bad — 曖昧、トリガーなし
description: ドキュメント処理7項目チェックリスト
| # | チェック | 悪い例 | 良い例 |
|---|---|---|---|
| 1 | What: 何をするか明記 | "ドキュメント処理" | "PDFからテーブルを抽出しCSVに変換" |
| 2 | When: いつ使うか明記 | (なし) | "データ分析ワークフローで使用" |
| 3 | トリガーワード含有 | (なし) | "「記事QC」「バリデーション」で起動" |
| 4 | 具体的なアクション動詞 | "管理する" | "抽出・変換・検証する" |

| 6 | 既存スキルと差別化 | 他スキルと被る | 独自の守備範囲を明示 |
| 7 | ネガティブトリガー | なし（誤発火リスク） | "Do NOT use for: ..." |
Descriptionデバッグ手法
発火しない場合、Claudeに聞け：
「When would you use the [skill-name] skill?」
Claudeがdescriptionを引用して答える。足りない要素が見える。
3つのユースケースカテゴリー
スキル設計前に、どのカテゴリーか特定する：
| カテゴリ | 用途 | 例 |
|---|---|---|
| 1. Document & Asset Creation | 成果物生成（PDF, コード, 記事等） | shogun-seo-writer |
| 2. Workflow Automation | ステップバイステップの自動化 | shogun-git-release |
| 3. MCP Enhancement | MCPツール+ワークフロー知識 | shogun-github-reviewer |
5つの設計パターン
Pattern 1: Sequential Workflow（順序付き処理）
ステップ間に依存関係あり。各ステップにバリデーション + 失敗時ロールバック。
Pattern 2: Multi-Service Coordination（複数サービス連携）
フェーズ分離 + データ受け渡し + フェーズ間バリデーション。
Pattern 3: Iterative Refinement（品質ループ）
生成 → 検証スクリプト → 改善 → 再検証。品質閾値で停止。
Pattern 4: Context-aware Selection（条件分岐）
コンテキストに応じてツール/手法を動的選択。判断理由をユーザーに説明。
Pattern 5: Domain Intelligence（専門知識埋め込み）
ドメイン固有ルールをロジックに組み込む。コンプライアンス・監査証跡。
Dynamic Features（動的機能）
引数置換
/my-skill 結婚 kekkon$ARGUMENTS→結婚 kekkon（全引数）$0→結婚（第1引数）$1→kekkon（第2引数）
$ARGUMENTS を本文で使わない場合、末尾に自動追加される。
動的コンテキスト !command``
スキル読み込み前にシェルコマンドを実行し、結果を埋め込む：
## 現在のブランチ
!`git branch --show-current`
## 最近のコミット
!`git log --oneline -5`Execution Patterns（実行パターン）
Pattern A: インライン実行（デフォルト）
メイン会話内で直接実行。ガイドライン型・短いタスク向け。
Pattern B: Fork実行（隔離）
context: fork でサブエージェント実行。重い処理・大量出力向け。
注意: ガイドラインだけのスキルにforkを使うな。サブエージェントには明確なタスクが必要。
Pattern C: 手動専用（副作用あり）
disable-model-invocation: true でClaude自動発火を禁止。/name でのみ起動。
File Structure（ファイル構成）
~/.claude/skills/skill-name/
├── SKILL.md # 必須。5,000語（約500行）以内。case-sensitive
├── scripts/ # 任意。バリデーション等の実行スクリプト
├── references/ # 任意。詳細なAPI仕様・ルール集
├── assets/ # 任意。テンプレート、フォント、アイコン
└── examples/ # 任意。入出力サンプル命名規則
- フォルダ名: kebab-case（
notion-project-setup✅ /Notion_Setup❌） SKILL.mdは大文字小文字厳密（skill.md❌ /SKILL.MD❌）- README.md禁止（スキルフォルダ内）。ドキュメントはSKILL.md or references/に
Progressive Disclosure（3層構造）
| 層 | 内容 | 読み込みタイミング |
|---|---|---|
| L1 | YAML frontmatter | 常時（システムプロンプト内） |
| L2 | SKILL.md本文 | スキル関連と判断された時 |
| L3 | references/, scripts/ | 必要に応じてClaudeが参照 |
SKILL.md本体は5,000語以内。詳細はreferences/に分離。
テスト戦略（3領域）
1. Triggering Test（発火テスト）
Should trigger:
- "新しいスキルを作りたい"
- "SKILL.mdのレビュー"
- "スキル設計して"
Should NOT trigger:
- "スキルを実行して"
- "天気教えて"
- "コード書いて"Show full SKILL.md (153 more words)Show less
2. Functional Test（機能テスト）
- 正しい出力が生成されるか
- エラーハンドリングが動作するか
- エッジケースが処理されるか
3. Performance Test（性能テスト）
スキルあり/なしの比較：
- ツール呼び出し回数
- トークン消費量
- ユーザーの手戻り回数
Pro Tip: まず1つの難しいタスクで反復。成功したアプローチをスキル化。 その後テストケースを広げる。
Creation Workflow（作成フロー）
スキル作成時、以下を順に実行：
- ユースケース特定: 2-3個の具体的シナリオを定義
- カテゴリ判定: Document / Workflow / MCP Enhancement
- description設計: 7項目チェック + ネガティブトリガー + 1024文字以内
- 既存スキルとの重複チェック:
ls ~/.claude/skills/で確認 - 実行パターン選択: インライン / fork / 手動専用
- allowed-tools設計: 必要最小限に制限
- 引数設計:
$0,$1→argument-hint記載 - 動的コンテキスト:
!command`` で事前取得すべきデータ検討 - SKILL.md執筆: 5,000語以内。重要指示はファイル上部に配置
- バリデーションスクリプト化: クリティカルなチェックはscripts/に（コードは決定的、言語は非決定的）
- テスト: Triggering / Functional / Performance の3領域
- 設置:
~/.claude/skills/skill-name/に配置
バリデーションスクリプト推奨
公式ガイドの最重要Tips: クリティカルなバリデーションはスクリプトで行え。 コードは決定的、言語の解釈は非決定的。
# scripts/validate.sh の例
#!/bin/bash
# 出力ファイルの品質チェック
if [ $(wc -w < "$1") -lt 100 ]; then
echo "ERROR: Output too short (min 100 words)"
exit 1
fi将軍システム固有ルール
- 保存先:
~/.claude/skills/shogun-{skill-name}/ - スキル候補は足軽が発見 → 家老経由で将軍に報告 → 将軍が設計 → 殿が承認 → 家老が作成
- 将軍システム連携（inbox_write, task YAML等）が必要なスキルは allowed-tools に Bash を含めよ
- north_star はフロントマターでなく本文に記載（フロントマターのカスタムフィールドはClaude Codeに無視される）
Anti-Patterns（やってはいけないこと）
| NG | 理由 | 代わりに |
|---|---|---|
| SKILL.md 5,000語超 | 読み込みコスト爆増、応答品質低下 | references/ に分離 |
| description が曖昧 | 発火しない or 誤発火 | What + When + ネガティブトリガー |
| description 1024文字超 | フロントマター制限超過 | 簡潔に3文以内 |
description に < > | セキュリティ違反 | 角括弧不使用 |
| ネガティブトリガーなし | 類似スキル間で誤発火 | "Do NOT use for: ..." 追加 |
context: fork + ガイドラインのみ | サブエージェントが迷走 | インライン実行 |
disable-model-invocation + user-invocable: false | 誰も起動できない | どちらか片方 |
| allowed-tools 未指定で重い処理 | 意図しないツール使用 | 必要なツールのみ列挙 |
| フロントマターに独自フィールド | Claude Codeに無視される | 本文のMarkdownに記載 |
| スキルフォルダにREADME.md | 仕様違反 | SKILL.md or references/ |
| 同時有効スキル50個超 | コンテキスト圧迫 | 選択的有効化 |
