WHY IT NEEDS A POLICY

Why set_vehicle_main_image needs a policy

This is a Write operation because it modifies metadata (the designation of which image is primary) for an existing vehicle record. The severity is medium because misuse could affect vehicle listings' visual presentation and potentially mislead buyers, but the action is fully reversible and does not permanently delete data, execute code, or commit financial transactions.

From the tool's definition Tool description states 'Set a specific image as the main/primary image for a vehicle' and 'Change which image shows first in listings' — this modifies vehicle listing data by reordering/selecting which image displays prominently.
