When to use this skill

• 피처 개발: 새 기능을 작은 태스크로 분할
• Sprint Planning: 스프린트에 포함할 작업 선정
• Backlog Grooming: 백로그 정리 및 우선순위 설정

Instructions

Step 1: User Story 작성 (INVEST)

INVEST 원칙:

• Independent: 독립적
• Negotiable: 협상 가능
• Valuable: 가치 있음
• Estimable: 추정 가능
• Small: 작음
• Testable: 테스트 가능

템플릿:

## User Story: [제목]
As a [사용자 유형]
I want [기능]
So that [가치/이유]
Acceptance Criteria
[ ] Given [상황] When [행동] Then [결과]
[ ] Given [상황] When [행동] Then [결과]
[ ] Given [상황] When [행동] Then [결과]

Constraints

필수 규칙 (MUST)

• 명확한 AC: Acceptance Criteria 필수
• 추정 완료: 모든 스토리에 포인트 할당
• 의존성 파악: 선행 작업 명시

금지 사항 (MUST NOT)

• 너무 큰 스토리: 13+ points는 분할
• 모호한 요구사항: "개선한다", "최적화한다" 금지

Best practices

• INVEST 원칙: 좋은 사용자 스토리 작성
• Definition of Ready: 스프린트 시작 전 준비 완료
• Definition of Done: 명확한 완료 기준
