Multi-turn tool-use scenario.
Tools involved: MessageAPI
TradingBot

User requests (one per turn):
user: Hi there! I've noticed a stock have been slipping more than I'd like. Would you be able to pull up their stock information for a quick review and also make sure it's no longer on my watchlist?
user: The stock name is Zeta Corp.
user: Could you compile a list of all the stocks currently on my watchlist? I'm aiming to get a better grip on my portfolio management.
user: I think it would be wise to let my friend know about the changes I'm making, specifically regarding Zeta Corp. Please send a note to my friend's user ID USR003 stating, 'I've decided to drop those dipping stocks from my line-up.' My user id is 'USR002'.
user: Would you mind showing me any recent messages I've sent?
user: My friend mentioned something quite irrelevant and outdated in one of the messages. Can you help me by delete message id: 67410?
