telegram_download_file
AI agents call telegram_download_file to retrieve information from Agent Telegram without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Downloading a file is a read operation that retrieves data without modifying or deleting it. Severity is medium because downloaded files could contain sensitive information depending on chat context and user permissions, but the operation itself has no destructive side effects. Confidence is 0.85 due to the empty tool description, but the name and server context clearly indicate data retrieval.
