WHY IT NEEDS A POLICY

Why organize_by_type needs a policy

This tool modifies the file system structure by creating subdirectories and reorganizing file placement. While the server emphasizes 'safe' operations, organizing files involves writes (directory creation, file movement) rather than reads. The operations are reversible—files can be moved back and directories can be recreated—which distinguishes it from Destructive actions.

From the tool's definition Tool description states it 'Organize[s] files into subdirectories' and 'Automatically cleans up empty source directory.' This involves creating new directory structures and moving/reorganizing files (reversible operations).
