Or tell you how to use the tools you already have, but sure whatever. The point is, "LLMs that actually do stuff" end up partly looking like expensive logic to decide what to do (like an interpreter) and actually doing it, in terms of some preexisting set of primitives. The expensive logic does get you a high degree of flexibility for less programming cost, but you pay a lot for interpretive overhead. I really do think something that looks like a tracing hit (and a standard set of tools or primitives) could find "straight line" paths a reasonable fraction of calls. But if the interpreter is a service that you pay for by the token, and which is already losing money, why should it be written to do so?
