WHY IT NEEDS A POLICY

Why convert_file_encoding needs a policy

The tool modifies file encoding, which changes file content. While the operation is reversible (via automatic backups), it alters data state. This is a Write operation - it updates existing files rather than reading, executing arbitrary operations, or permanently destroying data.

From the tool's definition Tool "converts" files "to specified encoding" with "automatic backup support", modifying file content reversibly. The description indicates it modifies existing files rather than creating new ones, placing it in the Write category rather than Create.
