LLM that can call multiple tool APIs with one request

If I'm really leaning into multi-tool use for anything resembling a mutation, then I'd like to see an execution plan first. In my experience, asking an AI to code up a script that calls some functions with the same signature as tools and then executing that script actually ends up being more accurate than asking it to internalize its algorithm. Plus, I can audit it before I run it. This is effectively the same as asking it to "think step by step."

I like the idea of Command R+ but multitool feels like barking up the wrong tree. Maybe my use cases are too myopic.
