Three steps

  1. Create a free 0n3 account and connect WhatsApp Business. Paste a key or sign in; it lands in your vault, encrypted.
  2. Install 0n3 into Claude Code. The terminal agent. One command, then every connection you hold is a tool in your shell. The skill file teaches it how 0n3 works.
  3. Ask Claude Code: whoami. Then: "Send a text message in WhatsApp Business".
Install (user scope — every project)
