WHAT IT DOES

What create_folder does on Google Connections

AI agents use create_folder to create or update resources in Google Connections — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Connections environment.

WHY IT NEEDS A POLICY

Why create_folder needs a policy

This tool creates a new folder, which is a reversible write operation. It modifies the file system state by adding a new container but does not execute arbitrary code, delete data, or move money. The medium severity reflects that while folder creation itself is benign, an agent could create numerous folders to consume storage quota or create confusing organizational structures.

From the tool's definition Tool name 'create_folder' and description 'Create a new folder in Google Drive' indicate creation of new data structure in cloud storage.
