## Cross-Skill Integration

| Trigger | Partner Skill | How |
|---------|---------------|-----|
| "관련 법률도", 임대차/전세 분쟁 | `law-search` (~~law) | 주택임대차보호법, 부동산거래신고법 검색 |
| "주변 환경도", 입지 분석 | `kma-weather` (~~weather) | 해당 지역 기후/환경 데이터 보강 |
| "투자 관점에서" | `finance-sector-analysis` | 부동산 섹터(XLRE) 분석 연동 |

### Cross-Skill: Real Estate + Legal Context
1. `real_estate.sh` → transaction data
2. `law-search` → 관련 법률 (주택임대차보호법, 부동산거래신고법 등) (via ~~law)
3. Append legal references to report

### Cross-Skill: Real Estate + Location Environment
1. `real_estate.sh` → transaction data
2. `kma-weather` → 지역 기후/미세먼지 데이터 (via ~~weather)
3. Add environmental context to area comparison

## Notes
1. District code: 5 digits (시군구 level)
2. Contract month: YYYYMM format
3. dealAmount contains commas → parse as string
4. Data delay: 1-2 months after actual transaction
5. Pagination: increase pageNo for large datasets
