Multi-turn tool-use scenario.
Tools involved: TwitterAPI
VehicleControlAPI

User requests (one per turn):
user: Hey, I've just filled my car up with 13.2 gallons of fuel. How much is that in liters?
user: Once you've converted it to liters, please guide me in filling the tank to the max limit. After that's sorted, I need to ensure that all the doors are securely locked and the parking brake is firmly set.
user: With the car prepped, I need to gear up for a drive to Rivermist. I'll be checking the fuel level once the engine is on in 'START' mode. Then, help me post a tweet, 'Embarking on an exciting road trip from SF to Rivermist!' and please throw in hashtags #RoadTrip #Adventure #Exploring.
user: I'm leaving from San Francisco.
