You're treating an agent like its something other than an LLM with limited context. I'm just trying to surface a incorrect assumption.

You're just talking about LLMs. Whether they're a child of a primary LLM is irrelevent to your conception.

It'd be interesting if you posited that LLMs doing functional style could handle more context without service degradation.
