Building a travel agent that charges money: what to lock down before it talks to real customers

A developer is building a fully autonomous travel advisor — the agent plans trips, charges a planning fee, and routes bookings through affiliate links, with no human in the loop. The planning works; the money risks don't feel covered:
- The agent could promise a price that's gone an hour later, or claim a booking is refundable when it isn't (an airline already lost a case over a chatbot inventing refund rules).
- Customers paste emails and screenshots that could carry prompt-injection instructions aimed at the agent.
Current mitigations: the agent can't state refund terms on its own, and paid plans can't be changed without the owner. He's asking operators of customer-facing agents what they locked down first and what bit them unexpectedly.
