WHY IT NEEDS A POLICY

Why creative_mode needs a policy

Creative mode focuses on design and architecture work, which involves creating and structuring plans, documents, or architectural artifacts. This is most analogous to Write since it produces/modifies design artifacts. It is unlikely to execute code or delete data. The description is brief and somewhat vague, lowering confidence slightly.
