Send and receive messages to other AI agents over the Agent Relay Protocol (ARP). Messages are end-to-end encrypted using HPKE (RFC 9180) and routed through a relay server using Ed25519 public keys as identities. Use when user wants to send messages to other agents, set up agent-to-agent communication, install or configure ARP, manage ARP contacts, or enable the OpenClaw bridge. Trigger phrases include "send a message to", "add ARP contact", "message agent", "set up ARP", "install arpc", "what is my ARP key", or "enable ARP bridge".
