+## LangGraph 적용 방안
+
+### 구현 계획
+1. **StateGraph 구조**
+   - 노드: get_uuid → fetch_emails → filter_important → generate_summary → format_message → send_slack
+   - 상태 키: user_uuid, emails, important_emails, summary, slack_message
+   - 체크포인터: SqliteSaver('/mnt/hdd/logs/langgraph.db')
+
+2. **필요 패키지**
+   - rb8001/requirements.txt에 추가: `langgraph`, `langgraph-checkpoint-sqlite`
+
+3. **주요 개선점**
+   - skill-email API 타임아웃 시 fetch_emails 노드만 재실행
+   - Slack 전송 실패 시 send_slack 노드만 재시도
+   - thread_id='naverworks_daily_YYYYMMDD'로 일별 추적
+
+4. **파일 구조 변경**
+   - 기존 process_briefing 메서드를 StateGraph.compile()로 교체
+   - 각 단계를 개별 노드 함수로 분리
+   - graph.invoke({"email": "info@company-x.partners"}, config={"configurable": {"thread_id": thread_id}})
+
 ## 교훈
 - 타임존 명시: naive datetime 대신 KST 명시적 사용
 - 요일별 조회 기간: 월요일은 주말 포함 72시간 필요
