The most impressive agent demo is often the one that keeps going. It researches, plans, calls tools, revises, and returns with a finished artifact. But in a real product, the agent that always keeps going is rarely the one people trust.

Useful autonomy is bounded autonomy. A good agent has a crisp understanding of what it can decide, what it must surface, and when the cost of another action exceeds the likely value.

Boundaries are product decisions

A boundary is not merely a safety constraint added after the experience is designed. It is part of the experience. It tells a person where their judgment enters the loop and makes the system’s behavior easier to predict.

Start by mapping actions across three zones: reversible and low-impact, reversible but consequential, and hard to reverse. Let the agent move freely in the first zone. Add lightweight confirmation in the second. Keep a person firmly in charge of the third.

Design the handoff, not just the task

Stopping well is a skill. An agent should be able to say what it accomplished, what remains uncertain, and what decision it needs from a person. That handoff should feel like a capable colleague bringing you into the work at exactly the right moment.

The goal is not maximum autonomy. The goal is maximum useful progress with an appropriate level of human attention.
