An assistant becomes useful when it knows what it is responsible for, which sources it may use and which actions it may take. We define those boundaries around the person or function it supports. Broad access and an open-ended instruction are not substitutes for a working role.
We connect the appropriate knowledge and task workflows, then design how someone asks for work, reviews the response and corrects the context. The assistant should make its limits understandable. Where information is missing or an action requires authority, it asks or escalates.
