수도권 버스 도착 알림 (Clawdbot cron)

Scheduled bus arrival alerts powered by 국토교통부 TAGO OpenAPI.

This skill is designed for users running Clawdbot Gateway + Clawdbot cron. Users register rules like:

• "평일 오전 7시, 인천 한빛초등학교, 535"
• "평일 오후 5시30분, 고양 향동초등학교, 730, 503"

Then the system sends arrival summaries to the registering user (DM) on schedule.

Note (MVP): stop resolution is done via stop name search (cityCode + keyword). GPS-based nearby lookup exists but may return 0 results depending on key/region.

Prerequisites

• A running Clawdbot Gateway (Telegram/Slack/etc. already configured)
• Clawdbot cron enabled/usable
• A data.go.kr API key for TAGO

One-time setup: TAGO API key

You must set a TAGO service key in your environment (never commit or paste it into markdown).

Recommended env var:

• TAGO_SERVICE_KEY

Option A (fastest): one-off test in your current shell

Good for quick manual tests; cron jobs will NOT inherit this unless the Gateway service has it.

export TAGO_SERVICE_KEY='...'

Option B (recommended): one-command setup (auto-detect systemd unit)

This is the most “set it once and forget it” flow.

Run:

python3 korea-metropolitan-bus-alerts/scripts/setup.py

If your network blocks the endpoint or TAGO returns 403 during the smoke test, you can still complete setup:

python3 korea-metropolitan-bus-alerts/scripts/setup.py --skip-smoke

It will:

• Auto-detect your Gateway systemd user service (supports custom unit names)
• Prompt for TAGO_SERVICE_KEY (hidden input)
• Save it to ~/.clawdbot/secrets/tago.env (chmod 600)
• Write a systemd override to load that env file
• Restart the Gateway
• Run a small TAGO smoke test

(Advanced/manual) If you prefer shell scripts, korea-metropolitan-bus-alerts/scripts/set_tago_key.sh is still available, but setup.py is the recommended UX.

Safety notes

• Never commit .env / tago.env.
• Avoid sharing outputs of docker compose config or similar commands that may print env values.

Quick start

A) Test TAGO connectivity (manual)

export TAGO_SERVICE_KEY='...'
python3 korea-metropolitan-bus-alerts/scripts/tago_bus_alert.py nearby-stops --lat 37.5665 --long 126.9780

B) Register an alert rule (interactive)

Tell the agent something like:

• "평일 07:00, 인천 한빛초등학교, 535 알림 등록해줘"

If the stop name is ambiguous (e.g., opposite side of road), the agent MUST ask a follow-up question to pick the correct direction/stop candidate before creating the rule.

C) List rules

• "버스 알림 목록 보여줘"

D) Delete a rule

• "버스 알림 3번 삭제해줘" (confirm before delete)

E) Test a rule (run now)

• "방금 등록한 규칙 테스트해줘" (one-time message)

Supported schedule expressions (MVP)

• 매일 HH:MM
• 평일 HH:MM
• 주말 HH:MM

(Phase 2: arbitrary cron expressions)

Cron implementation notes

• Use isolated cron jobs (sessionTarget: isolated) + deliver: true.
• Delivery is DM-only to the registering user.
• See references/cron_recipe.md and scripts/cron_builder.py.

Interactive registration helper (server-side)

For integration testing (and for power users), use:

• scripts/rule_wizard.py register

It will:

1. Ask for schedule/time/routes
2. Resolve stop candidates via GPS nearby lookup (direction disambiguation)
3. Generate the job JSON
4. Optionally call clawdbot cron add to register it

Data source

Single provider only (MVP):

• 정류장 조회: BusSttnInfoInqireService (15098534)
• 도착 조회: ArvlInfoInqireService (15098530)

Safety / Security

• Never write API keys/tokens/passwords into markdown files.
• For browser automation on logged-in pages: require explicit user confirmation.
• For destructive operations (cron delete): confirm before acting.
• DM-only delivery (MVP): do not broadcast to groups/channels.

Implementation notes

• Prefer scripts under scripts/ for deterministic behavior.
• Put detailed API field mappings in references/api_reference.md.

Deterministic helper script

Use scripts/tago_bus_alert.py for deterministic TAGO lookups:

• nearby-stops (GPS → stop candidates)
• arrivals (cityCode+nodeId → arrivals; optional route filtering)
