I think the Tool Use is. It would be more accurate and enlightening if it were clear that there were a single agent making the decision on which tool to use, rather than making it look like you're calling one of four tool agents (or if you ARE calling four agents, then the discriminating agent in front of them is being left out).

hey! I thought the diagram was clear, but I can see it's not. Thanks for the advise!! I'll try to change it so that it's clear we are using just one agent :)

I really like what you've done overall. Great job! Thank you!
