Comms Hub Bridge

Agent-to-agent messaging via a shared Comms Hub server. Supports send, receive, acknowledge, file sharing, and presence.

Setup

1. Copy config.json.example to config.json in this skill folder
2. Edit config.json with your hub connection details and agent name
3. All commands use node scripts/bridge-client.js <command>

Config Fields

*At least one of hubIp or hubHost is required.

Environment variables override config.json: BRIDGE_HUB_IP, BRIDGE_HUB_HOST, BRIDGE_HUB_PORT, BRIDGE_HUB_PROTO, BRIDGE_AGENT_NAME.

Commands

node scripts/bridge-client.js health

Send a message

node scripts/bridge-client.js send <recipient> "<subject>" "<body>" [priority]

Priority: normal (default), high, low.

Heartbeat Integration

Check inbox on every heartbeat or periodic interval:

1. Run: node scripts/bridge-client.js inbox
2. If messages exist → read, process, ack each
3. If high priority → respond immediately or alert human
4. Log activity to daily memory file

Programmatic Use (Node.js)

const bridge = require('./scripts/bridge-client');
const msgs = await bridge.inbox();
await bridge.send('aristotle', 'Status Update', 'Sprint complete.');
await bridge.ack(msgs[0].id);
await bridge.uploadFile('/path/to/file.md');

Message Flow

Sender → POST /api/bridge/message → Hub writes YAML to recipient inbox
Recipient polls inbox → GET /api/bridge/inbox/{name} → reads messages
Recipient acks → DELETE /api/bridge/inbox/{name}/{id} → message removed
