nano---Openclaw: Skill for Claude Code

Add WhatsApp Channel

This skill adds WhatsApp support to NanoClaw. It installs the WhatsApp channel code, dependencies, and guides through authentication, registration, and configuration.

Phase 1: Pre-flight

Check current state

Check if WhatsApp is already configured. If store/auth/ exists with credential files, skip to Phase 4 (Registration) or Phase 5 (Verify).

ls store/auth/creds.json 2>/dev/null && echo "WhatsApp auth exists" || echo "No WhatsApp auth"

Detect environment

Check whether the environment is headless (no display server):

[[ -z "$DISPLAY" && -z "$WAYLAND_DISPLAY" && "$OSTYPE" != darwin* ]] && echo "IS_HEADLESS=true" || echo "IS_HEADLESS=false"

Ask the user

Use AskUserQuestion to collect configuration. Adapt auth options based on environment:

If IS_HEADLESS=true AND not WSL → AskUserQuestion: How do you want to authenticate WhatsApp?

• Pairing code (Recommended) - Enter a numeric code on your phone (no camera needed, requires phone number)
• QR code in terminal - Displays QR code in the terminal (can be too small on some displays)

Otherwise (macOS, desktop Linux, or WSL) → AskUserQuestion: How do you want to authenticate WhatsApp?

• QR code in browser (Recommended) - Opens a browser window with a large, scannable QR code
• Pairing code - Enter a numeric code on your phone (no camera needed, requires phone number)
• QR code in terminal - Displays QR code in the terminal (can be too small on some displays)

If they chose pairing code:

AskUserQuestion: What is your phone number? (Include country code without +, e.g., 1234567890)

Phase 2: Apply Code Changes

Check if src/channels/whatsapp.ts already exists. If it does, skip to Phase 3 (Authentication).

Ensure channel remote

git remote -v

If whatsapp is missing, add it:

git remote add whatsapp https://github.com/qwibitai/nanoclaw-whatsapp.git

Merge the skill branch

git fetch whatsapp main
git merge whatsapp/main || {
  git checkout --theirs package-lock.json
  git add package-lock.json
  git merge --continue
}
