WHY IT NEEDS A POLICY

Why batch_update_resource_visibility needs a policy

This tool modifies resource visibility settings in bulk, which is a Write operation (reversible state change). Without a detailed description, confidence is moderate. The batch nature and education platform context (affecting access to course materials) warrant medium severity—misuse could restrict or expose educational resources to unintended audiences, but the effect is reversible through subsequent updates.

From the tool's definition Tool name 'batch_update_resource_visibility' explicitly indicates a batch update operation affecting resource visibility settings. The 'batch_' prefix and 'update' verb confirm Write semantics.
