An Access Profile is a least privilege boundary for an agent, derived from a plain description of its job. Describe what the agent is for, and Xybern proposes the set of actions it should and should not be allowed to take.
You write what the agent is meant to do in plain English. Xybern derives an allowed and disallowed action set, plus guardrails, so the agent starts from least privilege rather than full access.
Run a profile in shadow to watch what the agent would have been blocked from doing, without affecting live work. When the boundary looks right, switch it to enforce and actions outside the box are blocked or escalated.
As an agent's job changes, its profile can be re-derived from the new description, so the boundary tracks the work instead of drifting toward over-permissioning.
