-1. **인프라 자율 사용**: 에이전트는 프로젝트에 설정된 Docker 기반 인프라(PostgreSQL, Redis 등)를 사용자의 추가 승인 없이 자유롭게 구동(`docker-compose up -d`) 및 활용할 수 있습니다.
+1. **인프라 자율 사용**: 에이전트는 프로젝트에 설정된 Docker 기반 인프라(PostgreSQL 등)를 사용자의 추가 승인 없이 자유롭게 구동(`docker-compose up -d`) 및 활용할 수 있습니다.
 2. **협력적 기획, 독립적 실행**: 기능 기획과 설계(Architecture, Schema 등)는 사용자와 함께 논리적인 완결성을 갖출 때까지 충분히 논의합니다. 기획이 "완료 및 승인"된 후에는 후속 구현, 에러 디버깅, 자체 테스트를 추가적인 중간 확인 없이 에이전트가 주도를 가지고 끝마친 뒤 최종 결과를 보고합니다.
