AI agents call check_is_whatsapp to retrieve information from Automagik Tools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The verb 'check' combined with the interrogative structure indicates a query or status verification rather than modification, execution of external commands, or destructive operations.
