IAF Agent Bridge tools 3
delegateSend a prompt to Cursor Agent and wait until that Cursor turn is terminal, including tool work and any sub-agent follow-up Cursor performs before it stops. Returns Cursor's reply and the sessionId to reuse. A second call for a session that is still running is rejected. You decide CONTINUE, COMPLETE, or BLOCKED. Do not shell out to the agent binary.cancelCancel an in-flight Cursor turn by sessionId. Status is cancelled, killed, not-running (the turn ended and the session can still be resumed), or not-found.doctorReport Node, bridge version, Cursor CLI discovery, authentication state without secrets, and an optional ACP handshake.
