Code Review

Kitchen DevTool에 AI Copilot 기능을 도입하기 위한 RFC 문서를 추가해주셨네요. 전반적으로 기능 정의, 아키텍처, 로드맵 등이 체계적으로 잘 정리되어 있습니다. 제안된 기능이 개발 생산성과 코드 품질 향상에 크게 기여할 것으로 기대됩니다. 몇 가지 내용상 불일치하는 부분과 추가로 고려하면 좋을 만한 점에 대해 리뷰 코멘트를 남겼으니 확인 부탁드립니다.

[gemini-code-assist]

AI 기반 기능의 중요한 보안 위협 중 하나인 **프롬프트 인젝션(Prompt Injection)**에 대한 리스크와 대응 방안을 추가하는 것을 제안합니다.

사용자가 입력하는 채팅 내용이나 코드 주석 등이 LLM 프롬프트의 일부로 사용될 경우, 악의적인 입력으로 인해 의도치 않은 동작을 유발할 수 있습니다. 예를 들어, 시스템 명령을 무시하거나 민감한 정보를 노출하도록 유도할 수 있습니다.

대응 방안 예시:

• 사용자 입력을 프롬프트에 삽입하기 전 이스케이프 처리 또는 정제
• 시스템 프롬프트와 사용자 입력을 명확히 구분 (예: 구분자 사용)
• LLM의 응답을 파싱하여 위험한 코드가 포함되어 있는지 검사하는 response guard 강화

[gemini-code-assist]

MVP 기능 범위에 대한 내용이 섹션 5와 섹션 8에서 서로 다르게 기술되어 있어 명확화가 필요해 보입니다.

• 섹션 5 (핵심 기능 MVP) 에서는 Patch Proposal이 MVP 기능으로 포함되어 있습니다.
• 섹션 8 (단계별 로드맵) 에서는 Patch Proposal에 해당하는 패치 제안이 Phase 2 기능으로 명시되어 있고, Phase 1(MVP)에서는 제외되어 있습니다.

MVP 범위를 명확히 하기 위해 두 섹션의 내용을 일치시키는 것이 좋겠습니다.
