What cbs_save_dataset does on Nl Opendata

WHY IT NEEDS A POLICY

Why cbs_save_dataset needs a policy

The tool name strongly suggests writing/saving downloaded or processed datasets to local or persistent storage. This is a reversible Write operation (data can be deleted or overwritten later). Without a description, confidence is not higher, but the naming pattern alongside sibling tools (cbs_analyze_*, cbs_query_*) that retrieve and manipulate data suggests this completes a download-and-persist workflow.

From the tool's definition Tool name 'cbs_save_dataset' indicates persisting data to storage; description is empty, limiting certainty about exact behavior and scope.
