WHY IT NEEDS A POLICY

Why make_document_editable needs a policy

The tool name implies a write-like operation that changes the editability state of a document. However, the description is empty, which significantly lowers confidence. Based on the name alone, this appears to be a Write operation (modifying document state/permissions), not destructive since it doesn't delete anything, and not Execute since it doesn't run code.

From the tool's definition Tool name 'make_document_editable' suggests modifying the state or permissions of a document to allow editing.
