It would work with most other Tool enabled LLMs. RubyLLM abstracts away the format. Some will work better than the others, depending on the provider, but almost all have tool support.

Claude is just an example. I pulled the actual payloads by looking at what is actually being sent to Claude and what it is responding. It might vary slightly for other providers. I used Clause because I already had a key ready from trying it out before.
