WHAT IT DOES

What telegram_forward_message does on Agent Telegram

AI agents use telegram_forward_message to create or update resources in Agent Telegram — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Agent Telegram environment.

WHY IT NEEDS A POLICY

Why telegram_forward_message needs a policy

Forwarding a message creates new data (a message copy) in a destination chat, which is a reversible write operation. It does not execute arbitrary code, delete data irreversibly, or move money. The severity is medium because an agent could spam messages across chats or forward sensitive information to unintended recipients, but the action remains reversible (forwarded messages can be deleted).

From the tool's definition Tool is named 'telegram_forward_message' and described as 'Forward a message from one chat to another.' This creates a copy of a message in a new location, modifying the state of the destination chat by adding new content.
