About this skill
EARS Validation Skill
EARS (Easy Approach to Requirements Syntax) で要件を形式化・検証。
EARS Patterns
| パターン | 構文 | 用途 |
|---|---|---|
| Ubiquitous | THE [system] SHALL [requirement] | 常に満たす要件 |
| Event-driven | WHEN [event], THE [system] SHALL [response] | イベント発生時 |
| State-driven | WHILE [state], THE [system] SHALL [behavior] | 特定状態中 |
| Unwanted | THE [system] SHALL NOT [behavior] | 禁止事項 |
| Optional | IF [cond], THEN THE [system] SHALL [response] | 条件付き |
WHEN → DO
| WHEN | DO |
|---|---|
| 自然言語の要件 | EARS形式に変換 |
| 要件レビュー | 6項目チェックリスト実施 |
| 要件文書作成 | テンプレートに従って記述 |
Validation Checklist
- Pattern Compliance: 5パターンのいずれかに準拠
- System Name: システム名が明確
- SHALL Keyword: 必須要件に「SHALL」使用
- Measurable: テスト可能・測定可能
- Atomic: 単一の要件を記述
- No Ambiguity: 曖昧な表現がない
Conversion Examples
| 自然言語 | EARS形式 |
|---|---|
| ユーザーがログインできる | THE AuthModule SHALL authenticate users with valid credentials. |
| パスワードが間違っている時エラー表示 | WHEN invalid credentials are provided, THE AuthModule SHALL display an error. |
| SQLインジェクションを許可しない | THE InputValidator SHALL NOT accept SQL injection patterns. |
Priority Levels
| 優先度 | 説明 | 用途 |
|---|---|---|
| P0 | 必須 | リリースブロッカー |
| P1 | 重要 | 可能な限り実装 |
| P2 | 任意 | 時間があれば |

│ Issues: 0 │
└─────────────────────────────────────────┘
When not to use it
- →General writing
- →Non-requirement documents
Prerequisites
Limitations
- →Requires EARS pattern knowledge
- →Limited to requirement documents
How it compares
It provides a formal syntax approach to requirements, reducing ambiguity compared to natural language.
