“Use this agent to send rich RCS, MMS, or SMS business messages through nativeMsg and track recipient interactions. Invoke when the user wants to: send a message (plain text, media, buttons, or quick replies) to a phone number via a nativeMsg channel; list or retrieve available messaging channels (RCS, SMS/MMS, Facebook, etc.); or list, search, or retrieve registered contacts (Humans) in nativeMsg. This agent handles outbound message delivery and routes inbound responses (button taps, text replies) from recipients back to this conversation. Do not use for scheduling, analytics, or non-messaging tasks.
