Delete a role from a Discord server
AI agents call delete_role to permanently remove resources in Discord — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a role is a destructive action that cannot be undone without manual restoration. It removes permissions and organization structures from the server, potentially affecting all members assigned to that role. While not as severe as financial impact, this causes significant operational disruption and warrants high severity.
From the tool's definition Tool name is 'delete_role' and description states 'Delete a role from a Discord server' — the verb 'Delete' and action of removing a role permanently indicate an irreversible operation.
