description	Query and summarize Seoul subway congestion statistics via SK Open API (TMAP 대중교통). Use when the user asks for station/line-based train congestion or car-by-car congestion, time-slot checks (dow/hh), comparisons, or commute alerts.

Seoul Subway Crowd (SK Open API)

Inputs to collect

• Station name (required)
• Line name/number (optional but recommended)
• Direction (optional): up/down or inbound/outbound
• Time mode (optional): now/forecast

Workflow

1. Ensure SK_OPENAPI_KEY exists in environment.
2. Read endpoint and parameter mapping from references/api-map.md.
3. Run scripts/fetch_crowd.py with station/line/time arguments.
4. Return a short Korean summary:
   • 혼잡도 등급
   • 핵심 수치(있으면)
   • 한 줄 코멘트(이동 추천/회피 시간)
5. If API fails, return clear fallback with reason and next action.

CLI usage

python3 scripts/fetch_crowd.py --station "강남역" --line "2호선" --mode train
python3 scripts/fetch_crowd.py --station "홍대입구역" --line "2호선" --mode car --dow MON --hh 08

Output style

• Keep it short and practical.
• Prefer bullet list over tables on Discord.
• Include raw response path when debugging (--save-json).

Notes

• Do not hardcode API key.
• Normalize common line variants ("2", "2호선", "Line 2").
• If API schema changes, update references/api-map.md first.
