maxStep (roundtrips) don't work for Claude or Gemini

[janzheng]

I'm able to get OpenAI and Groq to output roundtrips w/ maxStep, but somehow any of the Claude models always outputs 1 step and stops. I'm not sure if I'm doing something wrong here, but I can't find anyone else running into this

Edit: basically the model just "does" everything in a single message, and doesn't seem to alternate tool calls...
Edit 2: Google models will also "lazy out" and not keep running multiple steps

Here is a working example:

You can ask something like "What is the weather in SF?" and it'll call the tools.

thanks! I'll play with it to figure out what I'm doing wrong / differently — the weird thing is switching out the model for OAI or Groq just works (for multi step)
