No kidding, what I didn’t realize when I gave it a go is that it’s not just an agent calling tools in the background, it’s actually an agent calling agents calling tools. One agent instance can start to get a little pricy, but trying to use an agent firing up other agents all day gets really expensive.

I do wonder tho how much of the design decisions are driven by the fact that the more you use their API, the more money Anthropic makes.
