AI agents misinterpret Google Flights round-trip data

A developer has identified a potential issue with how AI agents interpret flight search results from Google Flights. The core problem is that Google Flights presents round-trip fares as a single price, but doesn't explicitly state the return flight details unless specifically requested. This can lead agents to believe they have found a complete itinerary when, in fact, the return leg is still undecided. The developer proposes a solution involving an adapter that enforces specific input constraints and maintains the relationship between outbound and return flights to prevent agents from making incomplete promises.
