WHY IT NEEDS A POLICY

Why batch_rename needs a policy

Batch rename is a write operation that modifies file system metadata (names) but is reversible—files can be renamed again. It's not destructive (files aren't deleted), not execute (doesn't run arbitrary code), and not financial.

From the tool's definition Tool name 'batch_rename' and description 'パターンマッチによる一括リネームを行います' (performs batch renaming via pattern matching) indicates the tool modifies file names/metadata in bulk. This is a write operation that changes data.
