WHY IT NEEDS A POLICY

Why qf_export_csv needs a policy

This tool exports data to a persistent CSV file, which is a form of data creation and persistence. While file export itself is less severe than modifying application data, it creates artifacts and could be misused to exfiltrate or stage data. It's reversible (files can be deleted), distinguishing it from Destructive operations.

From the tool's definition Tool creates a new CSV file by exporting query results, which is a reversible write operation. Description states 'Export...to a CSV file and return file path', indicating file creation/writing.
