WHY IT NEEDS A POLICY

Why copy_files needs a policy

The tool creates new file copies in a different location, which is a reversible write operation. It does not delete originals (distinguishing it from Destructive), does not execute arbitrary code (Execute), and does not involve financial transactions. The severity is medium because unauthorized copying could lead to unauthorized data duplication and quota exhaustion, but the operation is reversible via deletion.

From the tool's definition Tool name 'copy_files' and description '复制百度网盘中的文件到新目录' (copy files in Baidu Pan to new directory) indicate file duplication/creation operations within cloud storage.
