Ouroboros 시리즈 03 — 방법론 01편: 엔지니어가 디자인씽킹을 강연하게 됐을 때 · 02편: 컨텍스트가 부족했다 02편에서 MCP 안에 오케스트레이션을 넣은 이야기를 했다. 메인 세션이 MCP 콜 하나를 던지면, 안에서 AC 트리를 파싱하고 병렬 세션을 띄우고 결과를 모아서 돌려준다고. 이번 글은 그 안에서 실제로 뭐가 일어나는지에 대한 얘기다

Ouroboros 시리즈 02 — 구조 01편: 엔지니어가 디자인띵킹을 강연하게 됐을 때을 먼저 읽으면 좋습니다. Ouroboros가 하는 일을 단순하게 말하면 이렇다. 인터뷰를 하고, Seed를 만들고, Acceptance Criteria를 분해하고, 각 AC를 실행하고, 평가한다. 이걸 하나의 세션에서 하면 문제가 생긴다. 컨텍스트가 바닥난다. AC가
