The tool-search gateway point matches what I've seen: the win isn't just fewer tokens, it's fewer wrong tool picks when two servers expose near-identical tools (e.g. three different 'search' tools). One thing I'd keep a dashboard for, though, is the stuff nobody thinks to ask about: an agent answers the question you asked, while a well-designed dashboard surfaces the anomaly you didn't know to ask about. A pattern that works nicely is having the agent run a small set of scheduled 'standing questions' and only alert on deltas, so you get the proactive part without staring at charts. Also +1 on evals for skills; a handful of golden queries per data source catches most regressions when the model changes.
