Every assistant expresses priorities. It decides when to be concise, when to escalate, what to omit, and which risk matters most. If your company has not specified those choices, a model or vendor default has.
Machine-usable guidance should begin with approved human principles. It should define what the system may do, what requires review, and what must never be inferred.
Start with one bounded workflow. Compare the agent's recommendations against real judgment calls, document failures, and keep a named human owner for every change.
