SQL Agent 스킬

사용 시기

  • 사용자가 자연어로 데이터베이스를 질의할 때
  • SQL 쿼리 생성 및 실행을 자동화할 때
  • 데이터베이스 스키마를 탐색하고 분석할 때

워크플로: query-writing

  1. sql_db_list_tables — 사용 가능한 테이블 목록 확인
  2. sql_db_schema — 관련 테이블의 DDL(CREATE TABLE) 조회
  3. SQL 쿼리 작성 — 스키마를 기반으로 정확한 쿼리 생성
  4. sql_db_query_checker — 쿼리 문법 및 안전성 검증
  5. sql_db_query — 검증된 쿼리 실행

워크플로: schema-exploration

  1. sql_db_list_tables — 전체 테이블 목록
  2. sql_db_schema — 각 테이블 DDL 조회
  3. 관계 매핑 — FK 관계 파악 후 정리

안전 규칙 (READ-ONLY)

  • SELECT만 허용: INSERT, UPDATE, DELETE, DROP, ALTER 금지
  • LIMIT 필수: 항상 LIMIT 10 (또는 사용자 지정 값) 사용
  • 스키마 확인 필수: 쿼리 작성 전 반드시 테이블 스키마 확인
  • HITL 승인: sql_db_query 실행 전 사람의 승인 획득 (프로덕션)

HITL 패턴

python
# HumanInTheLoopMiddleware로 sql_db_query 실행 전 중단
middleware=[
    HumanInTheLoopMiddleware(interrupt_on={"sql_db_query": True}),
]
# Command(resume="approve")로 재개
