WHY IT NEEDS A POLICY

Why update_folder needs a policy

The tool modifies folder metadata or organization reversibly without deleting data or triggering external operations. While it could affect document organization in a legal context (medium severity due to potential case management disruption), it is not destructive, not an execution of arbitrary operations, and not financial. 'Update' operations are categorized as Write.

From the tool's definition Tool name 'update_folder' and description 'Update a document folder' indicate modification of existing data structure. Context shows this is part of a legal case management system (Filevine) handling documents, projects, and case materials.
