WHY IT NEEDS A POLICY

Why export_report_file needs a policy

This tool creates or modifies files on the local filesystem by writing report content in HTML or Markdown format. While the generated file is described as 'read-only,' the act of writing/creating the file itself is a Write operation. It's not Destructive because it doesn't irreversibly delete data, and the 'read-only' designation limits subsequent modification.

From the tool's definition The tool description explicitly states "Write a read-only HTML or Markdown report file to a local path." The verb 'Write' and action of creating a file to disk are the primary indicators.
