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" ->coupevilleorclinton(ask if ambiguous). - •For delay questions, run
wsdot vesselsand 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_KEYis not set, tell the user: "SetWSDOT_API_KEYin your environment. Get a free key at https://wsdot.wa.gov/traffic/api/."
