RISK

Why neuron_update_group_members is rated Medium

This tool modifies group membership and member roles (promote/demote), which are data changes that can be reversed by adding members back or changing roles again. While it affects group structure and member permissions, the changes are not permanent or destructive. The blast radius is limited to a single group's membership management, though misuse could disrupt group operations or grant unintended permissions.

From the tool's definition Tool description states 'Add, remove, promote, or demote members in a WhatsApp group' - these are reversible modifications to group membership and roles.
