openclaw-placet-channel

OpenClaw channel plugin for Placet — human-in-the-loop reviews and messaging.

Installation

openclaw plugins install openclaw-placet-channel
openclaw gateway restart

Configuration

Add to ~/.openclaw/openclaw.json:

{
  "channels": {
    "placet": {
      "instanceUrl": "https://app.placet.io",
      "apiKey": "hp_your-api-key",
      "enabled": true,
      "agentName": "OpenClaw Agent"
    }
  }
}

Config Options

Option	Required	Description
instanceUrl	Yes	Placet instance URL
apiKey	Yes	Placet API key (starts with hp_)
agentName	No	Name for the auto-created agent (default: OpenClaw Agent)
agentId	No	Use an existing Placet agent instead of auto-creating
enabled	No	Enable/disable the channel (default: true)

Environment Variables

You can override config values with environment variables:

• PLACET_URL — overrides instanceUrl
• PLACET_API_KEY — overrides apiKey

How It Works

1. Outbound: OpenClaw sends messages to Placet via the REST API (POST /api/v1/messages)
2. Inbound: A background Socket.IO connection listens for user messages and review responses from Placet
3. HITL: OpenClaw tool confirmations are mapped to Placet review types (approval, text-input, selection)

Message Flow

Placet User                              OpenClaw Agent
    |                                          |
    |--- types message ----------------------->|  (Socket.IO → message:created)
    |                                          |--- processes...
    |<--- agent responds ----------------------|  (REST → POST /api/v1/messages)
    |                                          |
    |<--- needs approval (HITL) ---------------|  (REST → message with review)
    |    (Placet review UI appears)            |
    |--- approves/rejects -------------------->|  (Socket.IO → review:responded)

Development

npm install
npm test
npm run typecheck

Troubleshooting

• "Channel not configured": Ensure instanceUrl and apiKey are set in config or env vars
• WebSocket disconnects: The plugin auto-reconnects with exponential backoff (1s → 30s max)
• Agent not found: If agentId is set but doesn't exist, the plugin creates a new agent by name
