Antenna — Inter-Host OpenClaw Messaging (v1.3.4)

Send messages between OpenClaw instances over reachable HTTPS via the built-in /hooks/agent webhook.

Prerequisites

Each participating host needs:

1. OpenClaw gateway running with hooks enabled (hooks.enabled: true)
2. A reachable HTTPS endpoint for /hooks/agent
3. Antenna agent registered in gateway config (agents section)
4. hooks.allowedAgentIds includes "antenna"
5. hooks.allowedSessionKeyPrefixes includes "hook:antenna"
6. Host-specific Antenna config in:
   • antenna-config.json
   • antenna-peers.json

Normal path:

• Run antenna setup to generate the live runtime files.
• Use antenna-config.example.json and antenna-peers.example.json as tracked reference templates only.
