WHY IT NEEDS A POLICY

Why doc2x_materialize_convert_zip needs a policy

The tool writes extracted/materialized zip file contents to a specified output directory. While not destructive in the strict sense (data is not deleted or overwritten), it creates new files on the file system, which is a Write operation. Severity is medium because uncontrolled file writes could fill disk space, overwrite sensitive files, or extract malicious content from a zip archive if the source is untrusted.

From the tool's definition Tool name and description indicate file system operations: 'Materialize convert_zip (base64) into output_dir' and 'writes the zip file'. These are irreversible writes to disk that create or modify files.
