WHY IT NEEDS A POLICY

Why create_group needs a policy

This tool creates a new group chat, which is a reversible write operation. It modifies the user's Telegram account state by adding a new group resource. While it affects social connections, it is not destructive (groups can be deleted), not financial, not directly executing arbitrary code, and represents a persistent but reversible data modification.

From the tool's definition Tool name 'create_group' and description 'Создать обычную группу с указанными участниками' (Create a regular group with specified participants) indicates creation of a new chat group entity.
