Why workspace_doc_update needs a policy

The tool name implies a write operation (update) on workspace documents. The server context is a terminal access system with file management capabilities, making this likely a write operation that modifies documentation files. However, the empty description means we cannot confirm whether this could also be destructive (overwriting). Confidence is low due to the empty description.
