WHY IT NEEDS A POLICY

Why agenda_add_goal needs a policy

This tool creates a new goal record with optional metadata (type, areas, due date, target metric). It modifies state by inserting data into an agenda system, which is a Write operation. The action is reversible (goals can be deleted or modified later), so it does not qualify as Destructive.

From the tool's definition Tool name 'agenda_add_goal' and description 'Add a single goal to the agenda' indicate creation of new data (goal insertion). The phrase 'Add...to the agenda' explicitly describes a write operation that creates a new record reversibly.
