RISK

Why list_file_versions is rated Low

This tool queries and returns version history information about a file—a read-only operation with no side effects. It retrieves data that already exists without creating, modifying, deleting, or executing any operations. The low severity reflects that access to version history alone poses minimal risk unless the versions contain highly sensitive data, but the operation itself is non-destructive and reversible.

From the tool's definition Tool name 'list_file_versions' and description 'List previous versions of a file' indicate retrieval of historical metadata without modification or deletion of data.
