What must change before an agent can act
Software that recommends an action leaves the final decision elsewhere. Software that takes the action has been given authority by the organisation that connected it to data, tools and production services.
That authority can grow in useful stages. An agent may observe and explain, recommend a change, prepare work in a reversible environment, or act against a production system within explicit limits. At each stage, the practical question is what the agent can now make happen.
Some actions finish before a person can inspect or stop them. Prohibited actions therefore need to be blocked by the system in advance.
Human oversight still matters, but a named owner and an approval process cannot prevent an action that has already completed.
For actions the organisation permits, the owner needs evidence of what happened, authority to stop or revoke the workflow where intervention is still possible, and a workable recovery route if something goes wrong. The more serious the possible consequence, the stronger those controls need to be before the permission is granted.
