​
Unilateral Communication

When communicating with A2A-only agents (agents not registered with Spellguard), AMP uses unilateral mode.

​
Unilateral Send Request

interface UnilateralSendRequest {
  /** Sender agent ID (must be Spellguard-attested) */
  sender: string;
  /** URL of the A2A-only agent */
  a2aAgentUrl: string;
  /** Payload to send */
  payload: unknown;
  /** A2A method to use */
  method?: 'tasks/send' | 'tasks/get';
}

​
Unilateral Send Result

interface UnilateralSendResult {
  /** Whether the send was successful */
  success: boolean;
  /** Correlation ID linking request and response */
  correlationId: string;
  /** Response from the A2A agent (if successful) */
  response?: A2AResponse;
  /** Error message (if unsuccessful) */
  error?: string;
  /** Commitment IDs for audit trail */
  commitments: {
    outbound: { commitmentId?: string; archiveId?: string };
    inbound?: { commitmentId?: string; archiveId?: string };
  };
  /** Warnings about partial failures */
  warnings?: string[];
}
In unilateral mode, only the sender is Spellguard-attested. The recipient is a standard A2A agent with no Spellguard verification.
