What addValueToGroup does on Whistle

Why addValueToGroup is rated Medium

This tool creates or modifies data reversibly by adding values to groups—a Write operation. Severity is medium because while it modifies proxy configuration data, the effects are reversible (values can be removed) and the blast radius is limited to local proxy rules rather than system-wide or financial impacts. Confidence is 0.85 (description is in Chinese but clear intent is to add data to a collection).

From the tool's definition Tool name 'addValueToGroup' and description '将值添加到分组' (Add value to group) indicates creation/modification of data by adding values to an existing group within the Whistle proxy management system.
