WHY IT NEEDS A POLICY

Why create_workspace_folder needs a policy

This tool creates new data (a folder) within a workspace, which is a reversible write operation. It does not execute arbitrary code, delete data, move money, or retrieve existing data. The severity is medium because unauthorized folder creation could clutter workspaces or be used for social engineering/obfuscation, but the impact is limited to a single workspace object and can be undone by deleting the folder.

From the tool's definition Tool name 'create_workspace_folder' and description 'Creates a new folder in a workspace' indicate a create operation that modifies the workspace structure by adding a new folder.
