Your agent confirms a booking with a reference number, the details, and a status. The data is made up. A single agent cannot check its own work: an invented answer sounds exactly as sure as a real one. Split the job instead. One agent does the work, a second checks independently that the data exists, and a third makes the call. You watch the same booking run through the agent that invents a hotel and through the team that catches it, and you leave with the pattern and when it pays for itself.
