WHY IT NEEDS A POLICY

Why rename_file needs a policy

Renaming files is a write operation that modifies metadata reversibly. It does not execute code, delete data irreversibly, or transfer funds. While it can cause confusion if misused (e.g., renaming critical files), the blast radius is limited to the affected file's metadata and remains recoverable. Medium severity reflects potential for user disruption without permanent data loss.

From the tool's definition Tool name 'rename_file' and description indicating file/folder renaming on Baidu Pan (百度网盘中的文件或文件夹). Renaming is a metadata modification operation that creates a new state but is reversible—the original name can be renamed back.
