WHY IT NEEDS A POLICY

Why tp_create_workout needs a policy

This tool creates a new workout entry, which is a reversible data modification. It does not execute arbitrary code, delete data, or involve financial transactions. The blast radius is medium because an AI agent could create unwanted or malformed workouts in a user's training plan, but the action is reversible through deletion or editing.

From the tool's definition Tool name 'tp_create_workout' and description 'Create a planned workout' explicitly indicate creation of new data. The phrase 'Create' is a quintessential Write operation that modifies the user's training plan by adding a new workout record.
