About Me
I am JH Kang, a Generative AI Engineer who enjoys working happily.
After obtaining a Master’s degree from the Graduate School of Artificial Intelligence, I have been conducting research and development in AI models. Since the release of ChatGPT, I have focused on becoming a Generative AI specialist, concentrating on developing services utilizing LLMs. I enjoy growing together with colleagues and strive to apply the latest research trends to practical products.
구현과 설계 기록
직접 확인한 동작과 설계 과정에서 달라진 판단을 글로 남깁니다.
- FastMCP 사용자라고 모두 MCP Python SDK v2로 옮겨야 하는 건 아니었다
패키지 의존성과 연결 방식을 격리된 Python 환경에서 확인했습니다. 실행 코드와 결과를 함께 공개합니다.
- 사용자 승인을 회수했지만 A2A Task는 계속 실행됐다
승인 회수, 작업 취소, 쓰기 직전 권한 확인을 비교한 실험입니다. 실행 중인 작업과 애플리케이션 권한의 경계를 다룹니다.
- Agent를 위한 온톨로지는 전사 데이터 모델에서 시작하지 않는다
Agent가 답해야 할 질문에서 출발해 필요한 관계와 근거를 정하는 설계 관점을 정리했습니다.
