What it does
Ddd Context Mapping is an agent skill from revfactory/harness-100. DDD(Domain-Driven Design)의 바운디드 컨텍스트 식별, 컨텍스트 맵 작성, 이벤트 스토밍 수행을 위한 상세 방법론. '바운디드 컨텍스트', 'DDD', '도메인 모델링', '이벤트 스토밍', '컨텍스트 맵', '애그리거트 설계', '유비쿼터스 언어' 등 도메인 분석 시 이 스킬을 사용한다. domain-analyst와 service-architect의 도메인 분석 역량을 강화한다. 단, 인프라 배포나 코드 구현은 이 스킬의 범위가 아니다.
Its SKILL.md is about 780 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 Development, covering Domain-driven design. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Domain-driven design
Example prompts
- “/ddd-context-mapping”
Workflow steps
4 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 8e8d35c. 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 markdown).
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
Ddd Context Mapping loads about 777 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 225 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.

DDD Context Mapping — 도메인 주도 설계 컨텍스트 매핑 가이드
바운디드 컨텍스트 식별부터 컨텍스트 맵 작성까지의 체계적 방법론.
이벤트 스토밍 수행 절차
Phase 1: 도메인 이벤트 수집
규칙: 과거형 동사로 표현한다
예: "주문이 생성되었다", "결제가 승인되었다", "배송이 시작되었다"
수집 순서:
1. 핵심 비즈니스 흐름의 이벤트를 시간순으로 나열
2. 예외/실패 이벤트 추가
3. 외부 시스템 이벤트 추가Phase 2: 커맨드 → 이벤트 매핑
[사용자/시스템] → {커맨드} → [애그리거트] → <<도메인 이벤트>>
[고객] → {주문 생성} → [Order] → <<주문이 생성되었다>>
[결제 시스템] → {결제 승인} → [Payment] → <<결제가 승인되었다>>Phase 3: 애그리거트 식별
애그리거트 경계 판단 기준:
1. 트랜잭션 일관성 경계 — 함께 변경되어야 하는 객체 그룹
2. 불변식(Invariant) 보호 — 비즈니스 규칙을 보장하는 단위
3. 동시성 경계 — 동시 접근 시 충돌을 관리하는 단위Phase 4: 바운디드 컨텍스트 도출
| 신호 | 의미 |
|---|---|
| 같은 단어가 다른 의미 | 컨텍스트 분리 필요 (예: "계정" = 사용자계정 vs 금융계정) |
| 다른 팀이 소유 | 조직 경계 = 컨텍스트 경계 |
| 다른 변경 주기 | 독립 배포 필요 → 분리 |
| 다른 데이터 저장소 | 기술적 경계 = 컨텍스트 경계 |
컨텍스트 맵 관계 유형
| 관계 | 기호 | 설명 | 예시 |
|---|---|---|---|
| Shared Kernel | SK | 공유 도메인 모델 | 두 팀이 같은 Entity 사용 |
| Customer-Supplier | C/S | 상류/하류 관계 | 주문(상류) → 배송(하류) |
| Conformist | CF | 하류가 상류 모델을 그대로 수용 | 외부 API 모델 수용 |
| Anti-Corruption Layer | ACL | 모델 변환 계층 삽입 | 레거시 시스템 연동 |
| Open Host Service | OHS | 공개 프로토콜 제공 | REST API 공개 |
| Published Language | PL | 공유 언어(스키마) | Protobuf/Avro 스키마 |
| Separate Ways | SW | 독립 운영 | 통합 불필요 |
| Partnership | P | 대등한 협력 | 두 팀 공동 개발 |
컨텍스트 맵 예시:
┌─────────────┐ OHS/PL ┌───────────────┐
│ 주문 관리 │ ──────────────→ │ 결제 처리 │
│ (Order BC) │ │ (Payment BC) │
└──────┬──────┘ └───────┬───────┘
│ C/S │ C/S
▼ ▼
┌─────────────┐ ACL ┌───────────────┐
│ 배송 관리 │ ←───────────── │ 외부 PG 연동 │
│ (Shipping BC)│ │ (3rd Party) │
└─────────────┘ └───────────────┘애그리거트 설계 원칙
크기 결정 기준
작은 애그리거트 선호:
├── 트랜잭션 범위 최소화 → 동시성 충돌 감소
├── 메모리 사용량 감소
└── 변경 영향 범위 축소
예외 (큰 애그리거트 허용):
├── 불변식이 여러 엔티티에 걸침
├── 원자적 일관성이 반드시 필요
└── 최종 일관성으로 대체 불가애그리거트 간 참조 규칙
✅ ID 참조: Order.customerId (Customer 애그리거트의 ID만 보관)
❌ 직접 참조: Order.customer (Customer 객체를 직접 보관)
이유:
1. 애그리거트 경계 존중
2. 트랜잭션 격리
3. 독립적 저장소 사용 가능유비쿼터스 언어 사전 템플릿
| 용어 | 컨텍스트 | 정의 | 동의어 | 반의어/혼동 |
|------|---------|------|--------|-----------|
| 주문(Order) | 주문관리 | 고객의 상품 구매 요청 | 오더 | 장바구니(Cart)와 구분 |
| 계정(Account) | 사용자관리 | 로그인 가능한 사용자 단위 | 유저 | 금융계좌와 구분 |
| 계정(Account) | 정산관리 | 정산 대상 금융 계좌 | 계좌 | 사용자계정과 구분 |서비스 분해 안티패턴
| 안티패턴 | 증상 | 해결 |
|---|---|---|
| 나노서비스 | 서비스가 너무 작아 1-2개 API만 보유 | 관련 서비스 병합 |
| 분산 모놀리스 | 모든 서비스가 동기 호출 체인 | 이벤트 기반 비동기 전환 |
| CRUD 서비스 | 도메인 로직 없이 DB 프록시 역할 | 도메인 로직 내재화 |
| God 서비스 | 하나의 서비스에 과도한 책임 | 바운디드 컨텍스트 기준 재분해 |
| 공유 DB | 여러 서비스가 같은 테이블 사용 | 데이터 소유권 분리 |
