Doorfarer

Finds the best round trips from where someone lives, not just from one airport: it adds the train or bus to every airport they can reach and ranks all options door to door, by price, by total travel time, or balanced. Use it when someone wants flights from their home town, could fly from several airports, or asks for the cheapest or fastest way to get somewhere, e.g. "I live in New Haven: should I fly to Lisbon from JFK, Newark, Boston or Hartford?" Not for a search from one airport already chosen. For a one-way trip set one_way (the trip length is then ignored). Multi-city: search each leg as one_way only when the user gave dates for it; otherwise ask for the dates. Set mode only when the user says how they get to the airport (car, train, bus, any): by default a home in the US compares driving, a taxi to a near airport and public transport, and a home elsewhere uses the train or bus. A named departure airport is an ordinary search: pass it as from_airports, with the home town the user gave. A month or holiday without a year means the next one coming; don't ask which year, and don't ask for the trip length or to confirm a town: search, and the answer says what it assumed. Any town or village works. The first search from a town we haven't seen takes about 20 seconds while we look up its train and bus connections; tell the user you're checking the connections from their town to each airport. Later searches from that town take a second or two. Give the home town and where to: airport, city or country codes, a list of them, or a region such as "Iberia" or "Southeast Asia". For "anywhere", a continent ("Asia") or "somewhere warm" it finds the cheapest places itself: pass "anywhere", "abroad" (another country) or the continent, or for warm, sunny or a beach the countries that fit the season with anywhere true; it searches the best 6 cities door to door. Dates are optional, but `dates` says where they came from: use "assumed" when the user gave none and you picked them (or

Shows the cheapest month to travel from someone's home town to a place, for each airport within reach: the cheapest fare found for each month (or, where none is found, what that route usually costs) plus the train or bus to the airport and the transfer into the city. Takes a few seconds. Airports further than 8.5 hours from home are left out and named. Use it when the user's dates are flexible or they ask when it's cheapest to go; then call find_trips for the month they choose to get bookable trips. Needs the home town; months as "2027-03", at most 12. Prices per person, in the home currency unless `currency` is given.

Shows one trip from a find_trips answer step by step, door to door: leaving home, the train or bus to the airport, the airport wait, the flight, the transfer into the city and arrival, then the way back, with local times. Also gives the booking link and a calendar file (.ics) the user can add. Pass a trip id from the find_trips answer ("Trip ids, row by row", or a row's `id`). Use it when the user picks a trip or asks how the journey works. Ids are kept for 72 hours.

Tell Doorfarer's maker where Doorfarer fell short, so it can be fixed. Use it when a find_trips answer was wrong, confusing, or missing something you needed to help, or when the user asks you to pass something on. Write as the assistant that used the tool: what you asked for, what came back, what you expected instead. The report is about Doorfarer only, never about the user: leave out names, contact details, travel plans, reasons for travelling and anything the user said about themselves. Be specific and honest, including when the problem may have been your own call. Pass the search_id from the answer's last line. One report per search. If the user asked you to report something, tell them it's sent.
