Google Flights Live Audit

Use this for generated tools under ~/.imprint/google-flights, especially when search and booking need to prove one-way, round-trip, and multi-city behavior end to end.

Core Checks

Start from the actual generated tool files, not assumptions:

find ~/.imprint/google-flights -maxdepth 2 -type f | sort
bun test ~/.imprint/google-flights/search_flights/integration.test.ts
bun test ~/.imprint/google-flights/get_flight_booking_options/integration.test.ts

Check these contracts explicitly:

• search_flights emits selection_token and selected_flights.
• staged search_flights accepts both selection_token and prior selected_flights.
• get_flight_booking_options receives the complete ordered selected_flights array.
• one-way uses a single selected route group.
• round-trip and multi-city group connecting segments into logical route legs.
• open-jaw stays trip_type=multi_city; do not rewrite it as round trip.
• airline filters and bag filters alter the rendered Google request, not only result parsing.

Live Flow

For multi-city/open-jaw, verify the real staged flow:

1. Call search_flights with trip_type=multi_city and an ordered itinerary like BOM,SFO,2026-09-07;BOS,BOM,2026-10-12.
2. Pick a first-leg result and call search_flights again with that result's selection_token and selected_flights.
3. Pass the staged result's complete selected_flights array to get_flight_booking_options.
4. Confirm booking options include all selected route legs, not just the first leg.

Use exact user-requested dates, airports, and carriers. If the user asks about an Emirates/Qatar/etc. option, test that carrier with airlines=<code> instead of relying on the default sorted subset.

Backend Timing

Google Flights usually needs cdp-replay for stateful booking/search flows. Treat cold CDP startup separately from warm calls:

• first same-site CDP call can cost tens of seconds;
• subsequent pooled calls should be cheap, often a few seconds or less;
• audit budgets should not under-test parameters just because the first call was expensive.
