WHY IT NEEDS A POLICY

Why rename_inventory_item needs a policy

This tool modifies research data (an inventory item's name) reversibly without permanently deleting or destroying data. It falls squarely into the Write category. Severity is medium because renaming inventory items could cause operational confusion or impact downstream processes that depend on item naming conventions, but the change is reversible (can be renamed again).

From the tool's definition Tool description states 'Changes the name of any inventory item' — a modification operation that updates an existing resource's property.
