WHY IT NEEDS A POLICY

Why create_strength_workout needs a policy

From the tool's definition Tool name 'create_strength_workout' indicates creation of a new workout record. Sibling tools include 'create_running_workout' and 'create_swimming_workout', which are clearly Write operations that create reversible data structures.
