6. 백엔드 개발자가 배울 점

  • README에서 quickstart와 실제 설정 파일이 연결되는지 확인해야 한다.
  • CI, Dockerfile, package/build 설정은 재현 가능한 개발환경의 핵심이다.
  • 대형 repo일수록 public API와 internal 구현 경계를 문서화해야 유지보수가 가능하다.

7. 내 프로젝트에 훔쳐올 패턴

  • 루트 README를 제품 랜딩처럼 구성한다.
  • examples/docs/tests를 같은 흐름으로 연결한다.
  • release, contributing, security 문서를 운영 표면으로 둔다.

8. 주의할 점 / 안티패턴

  • star 수만으로 코드 품질을 단정하면 안 된다.
  • README와 실제 코드 구조가 다를 수 있으므로 build/test 실행 검증이 필요하다.
  • 대형 repo의 패턴을 작은 프로젝트에 그대로 복사하면 과설계가 될 수 있다.

9. vibe-grid / vibe-hr / jarvis / ehr-harness에 적용할 아이디어

  • vibe-grid: public API, examples, QA matrix를 repo root에서 쉽게 찾게 만든다.
  • vibe-hr: HR 업무 cycle별 demo와 검증 시나리오를 README/docs에 연결한다.
  • jarvis: raw 자료보다 compiled wiki page를 제품 표면으로 만든다.
  • ehr-harness: 설치, 실행, 안전장치, release log를 명확히 분리한다.
