Your agent needs a boundary, not a bigger model

Most teams begin an agent project by asking what the model can do. We begin with a different question: what is the system allowed to decide?

Capability without authority design creates a dangerous grey zone. The agent can propose, but nobody knows when it may act. It can call tools, but nobody has defined the financial or reputational threshold that should trigger a review.

Design the boundary first

A useful autonomy map has three zones:

1. Act — reversible, low-risk work the agent may complete.
2. Ask — ambiguous work that requires human judgment.
3. Stop — prohibited actions and conditions.

That map becomes part of the product, the evaluation suite, and the operating agreement with the team.

Reliability is not simply the percentage of correct answers. It is the system’s ability to behave correctly when certainty is low.

A smaller model inside a precise operating boundary often creates more business value than a more capable model placed inside a vague workflow.
