What if the best AI agent is the one that knows when NOT to do something?

We usually talk about better AI agents in terms of what they can do: more tools, better reasoning, longer workflows, more autonomy. But maybe an equally important capability is knowing when not to act. Imagine an agent handling your daily work. It gets an email, finds some information, starts a workflow, and then realizes: “There isn't enough information here to make a good decision.” Instead of guessing, it stops and asks you. That sounds simple, but knowing when to act, when to ask, and when to leave something alone is arguably a huge part of making an agent actually useful. So what do you think matters more for the next generation of AI agents: More autonomy, or better judgment about when to use that autonomy? And what would you personally consider a sign that an AI agent is actually becoming “smart” rather than just more capable?
