WHY IT NEEDS A POLICY

Why applyToActivities needs a policy

The tool updates zone settings on activities, which is a modification operation. This is categorized as Write rather than Execute because the effect is data mutation (reversible), not arbitrary code execution or deletion.

From the tool's definition Tool description states 'Apply sport settings to matching activities (updates zones)' — this modifies existing activity data via the 'updates' operation, which is reversible.
