If you are building an agent that can purchase goods, book paid services, issue refunds, allocate credits, or trigger any other financial commitment, the permission model is part of the product. It must define what the agent can do, what it can see, how much it can spend, when it must stop for approval, and how you can cut off access when something goes wrong.
A model can behave exactly as designed and still be dangerously over-authorized. Your goal is not merely to make the agent accurate. It is to make the agent’s authority explicit, limited, observable, and easy to withdraw.
