WHY IT NEEDS A POLICY

Why update_many_documents needs a policy

This tool creates or modifies data reversibly by updating multiple documents in a collection, which fits the Write category. Severity is high because batch updates to multiple documents in a production Google services integration (Drive, Sheets) can have broad impact if an agent misuses the selection or modification logic, potentially affecting many user records simultaneously.

From the tool's definition Tool name 'update_many_documents' explicitly performs 'Update multiple documents' as stated in description. The 'many' quantifier indicates batch modification capability.
