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.

Refresh backend preferences after material tool fixes:

bun run src/cli.ts probe-backends google-flights --tool search_flights --param trip_type=multi_city --param itinerary='SFO,LAX,2026-09-01;LAX,JFK,2026-09-04'
bun run src/cli.ts probe-backends google-flights --tool get_flight_booking_options --param selected_flights='<complete selected_flights JSON>'

Manual Repair Rules

Keep fixes in generated artifacts tight and contract-driven:

• group connecting segments by origin/destination continuity and same/next-day dates;
• stop grouping when a later segment returns to the route group origin;
• mint booking state through staged shopping calls before GetBookingResults;
• use structured parsing for selected_flights; avoid string slicing;
• keep wording generic: producer-sourced values, selected route groups, booking state.

After manual edits, run focused live tests and a full audit:

bun test ~/.imprint/google-flights/search_flights/integration.test.ts
bun test ~/.imprint/google-flights/get_flight_booking_options/integration.test.ts
bun run src/cli.ts audit google-flights --provider codex-cli --timeout 45m --out ~/.imprint/google-flights/.audit-report.json

Report concrete counts from the audit: graded units, invocations, parameters, broken, no-op, infra, bad params, and untestable. Do not summarize "works" without these numbers.
