Message Format

IM Capabilities

Each adapter declares its capabilities via IMCapabilities:

interface IMCapabilities {
  text: boolean;
  codeBlock: boolean;
  cardMessage: boolean;
  fileSend: boolean;
  imageSend: boolean;
  audioSend: boolean;
  buttonAction: boolean;
}

The Agent adapts its output format based on getCapabilities().
