WHAT IT DOES

What promote_admin does on Claudegram

WHY IT NEEDS A POLICY

Why promote_admin needs a policy

This tool grants admin privileges to a chat participant, which is a reversible write operation (admins can be demoted). However, it carries high severity because misuse could allow an AI agent to hand over control of a Telegram group/channel to arbitrary users, potentially enabling further abuse at scale.

From the tool's definition promote_admin — 'Назначить участника администратором с заданными правами' (Appoint a member as administrator with specified rights)
