WHY IT NEEDS A POLICY

Why updateIntervals needs a policy

This tool modifies activity intervals reversibly without deleting data or executing arbitrary code. It falls under Write operations that create or modify data. The severity is medium because incorrect updates could affect fitness tracking data, but the change is not irreversible and the scope is limited to interval modification within a single activity record.

From the tool's definition Tool name 'updateIntervals' and description 'Update intervals for an activity' indicate modification of existing data (intervals within an activity).
