어떤 스킬인가요?
PR을 올리기 전에 이번 변경이 오류를 만들었는지 집중적으로 확인하고 싶을 때 사용합니다. 전체 diff를 확보하고 바뀐 코드가 어떤 입력과 호출을 받는지 살펴보는 흐름입니다.
기존에 있던 문제와 이번 변경이 만든 문제를 나눠 달라고 요청하세요. 의심만 되는 부분보다 실패하는 조건과 코드 근거를 함께 받는 편이 유용합니다. 기준 브랜치를 정확히 지정하고 제공된 정보로 확인하지 못한 항목도 표시하게 할 수 있습니다.

현재 브랜치의 전체 변경과 주변 코드를 살펴 새로 유입된 버그를 찾습니다.
PR을 올리기 전에 이번 변경이 오류를 만들었는지 집중적으로 확인하고 싶을 때 사용합니다. 전체 diff를 확보하고 바뀐 코드가 어떤 입력과 호출을 받는지 살펴보는 흐름입니다.
기존에 있던 문제와 이번 변경이 만든 문제를 나눠 달라고 요청하세요. 의심만 되는 부분보다 실패하는 조건과 코드 근거를 함께 받는 편이 유용합니다. 기준 브랜치를 정확히 지정하고 제공된 정보로 확인하지 못한 항목도 표시하게 할 수 있습니다.
find-bugs로 현재 브랜치와 main의 변경을 검토해줘. 이번 변경에서 생긴 문제만 우선하고 실패 조건·파일 위치·관련 테스트를 알려줘.
받을 수 있는 결과문제 위치·영향·확인 근거
2026-10-05 작은 프로필 함수의 입력과 결과를 검토했습니다. 오류 재현과 수정 결과는 Node로 확인했습니다. 실제 서비스 전체를 검사한 기록은 아닙니다.
화면에 이름을 표시하는 함수라도 프로필이 없는 계정을 만날 수 있습니다. 이번 예제는 프로필이 없으면 ‘게스트’를 반환해야 한다는 조건을 먼저 적었습니다. 정상 이름을 넣은 경우와 빈 객체를 넣은 경우를 함께 보는 이유입니다.
// 수정 전
return user.profile.name.trim();
// 입력 {} → TypeError없는 속성에 접근하는 경로를 optional chaining으로 처리하고, 이름이 없거나 빈 문자열이면 기본 이름을 사용했습니다. 입력 조건과 결과가 연결되어 있어 다른 사람이 같은 문제를 재현하기 쉽습니다.
return user?.profile?.name?.trim() || "게스트";
{} → 게스트
{profile:{name:" 꼬마봇 "}} → 꼬마봇버그가 있다는 결론만 받으면 수정할 범위가 모호합니다. 어떤 입력에서 어떤 줄이 실패하는지, 기대하는 결과가 무엇인지 함께 요청하세요. 이 예제는 문자열 이름을 전제로 하므로 숫자나 다른 자료형까지 허용할지는 별도로 정해야 합니다.
스킬 지원 에이전트, Git과 저장소가 필요합니다. 기본 브랜치 조회 흐름에 GitHub CLI를 사용할 수 있습니다.
현재 사용 중인 스킬 지원 에이전트에 아래 요청을 붙여넣으세요. SKILL.md만 복사하면 보조 파일이 빠질 수 있어요.
https://github.com/getsentry/skills 에서 skills/find-bugs 스킬을 현재 에이전트의 스킬 폴더에 설치해줘. SKILL.md와 이 스킬이 참조하는 scripts·references·assets와 공통 파일을 함께 유지하고, 필요한 실행 환경과 추가 연결을 확인한 뒤 알려줘. 설치가 끝나면 find-bugs 스킬을 인식하는지 확인해줘.
“find-bugs 스킬을 사용해줘. 입력 자료: 기준 브랜치·전체 diff·관련 파일”처럼 요청하세요. 위의 예시를 내 자료에 맞게 바꿔도 좋아요.
예상 결과는 ‘문제 위치·영향·확인 근거’입니다. 필요한 내용이 포함됐는지 확인하세요. 입력 자료의 사실·숫자와 결과를 대조하고, 부족한 부분을 이어서 요청하세요.

List every file you reviewed and confirm you read it completely 2. List every checklist item and note whether you found issues or confirmed it's clean 3. List any areas you could NOT fully verify and why 4. Only then provide your final findings ## Output Format **Prioritize**: security vulnerabilities > bugs > code quality **Skip**: stylistic/formatting issues For each issue: * **File:Line** - Brief description * **Severity**: Critical/High/Medium/Low * **Problem**: What's wrong * **Evidence**: Why this is real (not already fixed, no existing test, etc.) * **Fix**: Concrete suggestion * **References**: OWASP, RFCs, or other standards if applicable If you find nothing significant, say so - don't invent issues. Do not make changes - just report findings. I'll decide what to address.
