Consider these three scenarios:
Scenario 1: Same Session
9:00 AM
User: Book me a flight to Paris next Tuesday.
Agent: I found three options. Which airline do you prefer?
9:02 AM
User: The cheapest one.
Agent: Booking the United flight for \$425...The agent needs to remember the flight search results from two minutes ago. This is obvious.
Scenario 2: Same Day, Different Session
9:00 AM
User: Book me a flight to Paris next Tuesday.
Agent: Booking the United flight for \$425. Done!
3:00 PM
User: What time does my Paris flight leave?
Agent: Your flight departs at 10:00 AM next Tuesday.The agent needs to remember the booking from six hours ago, even though the user might have closed and reopened the app. This is less obvious but still expected.
Scenario 3: Different Days
Monday, 9:00 AM
User: Remember, I prefer morning flights.
Agent: Got it, I'll prioritize morning flights for you.
Friday, 2:00 PM
User: Book me a flight to London next week.
Agent: I found three morning flights for you...The agent needs to remember a preference from four days ago. This is long-term state that should persist indefinitely.
Each scenario requires different state management. The challenge is designing a system that handles all three naturally.
