 # NaverWorks 브리핑 주말 이메일 누락 문제
@@ -46,29 +46,6 @@ tags: [naverworks, briefing, timezone, langgraph]
 - DB 연결: PostgreSQL (DATABASE_URL 환경변수)
 - API 인증: skill-email은 X-API-Key 불필요, skill-slack은 X-API-Key 필수
 
-## LangGraph 적용 방안
-**현재 상태**: LangGraph 미도입 (requirements.txt, 코드에 없음)
-
-### 구현 계획 (향후 적용 시)
-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 및 호환성**
-   - rb8001/requirements.txt에 추가: `langgraph`, `langgraph-checkpoint-sqlite`
-   - 주의: SQLAlchemy 2.0.35 사용 중, SQLAlchemyJobStore 호환성 검증 필요
-   - Python 3.11 내장 zoneinfo 사용 가능
-
-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
