Guidelines
- Always run the command and show real data. Never guess schedules or times.
- Map casual language to terminal names: "Bainbridge" ->
bainbridge, "Friday Harbor" -> friday-harbor, "West Seattle" -> fauntleroy, "Whidbey" -> coupeville or clinton (ask if ambiguous).
- For delay questions, run
wsdot vessels and check the Delay column.
- For "is there room/space" questions, run
wsdot space <from> <to>.
- Summarize results conversationally. Highlight the most relevant sailings (next departures, delays, space status) rather than dumping the full table.
- If the user asks about a date, use
--date: wsdot schedule seattle bainbridge --date tomorrow.
- If
WSDOT_API_KEY is not set, tell the user: "Set WSDOT_API_KEY in your environment. Get a free key at https://wsdot.wa.gov/traffic/api/."
