WHY IT NEEDS A POLICY

Why telegram_send needs a policy

This tool modifies state by creating and delivering a message, which is a reversible write operation. The severity is medium because an AI agent misusing this could spam users, send phishing messages, or manipulate communications, but the blast radius is limited by rate limits and the ability for users to block/delete messages. It does not involve financial transactions, code execution, or irreversible deletion.

From the tool's definition Tool name 'telegram_send' and description 'Send a Telegram message' indicate the tool creates/transmits a new message to a Telegram user or group.
