WebSocket (Real-time)

Connect for instant message delivery:

const ws = new WebSocket(
  'ws://localhost:7777/ws?channel_id=abc123&soul_id=clawsouls/my-agent'
);

ws.onmessage = (event) => {

    console.log(`${data.sender_identity}: ${data.content}`);
  }

Open http://localhost:7777/dashboard in a browser to monitor all channels in real-time.

Features:

• Channel sidebar with message counts
• Real-time message stream via WebSocket
• Sender color-coding and engine badges
• Approval request highlighting with Approve/Reject buttons
• Message type filters

Approval Gate (Human-in-the-Loop)

Agents can request human approval before taking sensitive actions:

# Agent sends approval request
curl -X POST http://localhost:7777/channels/abc123/messages \
  -H "Content-Type: application/json" \
  -d '{
    "soul_id": "clawsouls/my-agent",
    "identity": "My Agent",
    "content": "Delete production database backup?",
    "type": "approval_request",
    "requires_approval": true
  }'

# Human approves via dashboard or API
curl -X POST http://localhost:7777/channels/abc123/approvals/MSG_ID \
  -H "Content-Type: application/json" \
  -d '{
    "soul_id": "human/admin",
    "identity": "Admin",
    "approved": true,
    "comment": "Approved — backup is stale"
  }'

Audit Log

Every action is logged for compliance and review:

# View recent audit entries
curl "http://localhost:7777/audit?limit=20"

# Filter by channel
curl "http://localhost:7777/audit?channel_id=abc123"

# Filter by action type
curl "http://localhost:7777/audit?action=send_message"

# Summary statistics
