A role is a set of responsibilities
“Sales Outbound” is only a label until you define the deliverable. Research, prioritization, drafting, and sending are different responsibilities. Make the boundary visible.
Context makes the role specific
A good brief includes the audience, the inputs, and an example of the expected output. These details do more for consistency than a long list of personality traits.
Review is part of the workflow
Tell the bee how you will judge the work. Ask it to flag missing information and explain assumptions. The result should make your decision easier, not hide uncertainty.
