WA-Relay — WhatsApp Message Firewall

A relay skill that acts as a controlled gateway between the OpenClaw agent and third-party WhatsApp contacts. The main agent never interacts directly with third parties — all communication is mediated through this relay.

How It Works

Inbound Flow (Third Party → Owner)

1. A message arrives from a WhatsApp contact that is NOT the owner
2. The main agent responds with NO_REPLY (does not send anything to the third party)
3. The main agent notifies the owner via WhatsApp using the message tool:
   • Who sent the message (name + number)
   • What they said (full text)
   • Timestamp
   • If it's audio, transcribe first then relay the transcript
   • If it's media (image/video/document), describe it and forward if possible
