## Why Update_Group is rated Medium

This tool modifies group configuration or metadata within Files.com. As an update operation, it creates reversible changes to existing resources. The severity is medium because unauthorized group modifications could affect access controls and user permissions, but the changes are not destructive (can be reverted) and do not directly move money or execute arbitrary code.

From the tool's own definition: "Tool name is 'Update_Group' and description states 'Update Group'. Update operations modify existing data reversibly."

## Use case

AI agents use Update_Group to create or update resources in Files Com, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Files Com environment.
