WHY IT NEEDS A POLICY

Why send_video_note needs a policy

Sending a message is a Write operation: it creates new data (a message) in the target chat, but the action is reversible (the message can be deleted). The severity is medium because an AI agent could spam contacts, send inappropriate content to unintended recipients, or harass users, but the impact is limited to message creation without financial loss, data destruction, or code execution.

From the tool's definition Tool sends a video note to a Telegram chat. The description states 'Отправить video-кружок' (send video circle/note), which creates a new message object in the Telegram account. This is a reversible write operation—messages can be deleted afterward.
