WhatsApp Local Router

Overview

Handle two WhatsApp input types and mirror backend responses back to the user:

• Text input → /process
• QR image input → /decode-qr

Always send the endpoint response body back to the user with no extra formatting unless the user asks for explanation.

Workflow

1. Confirm the message comes from WhatsApp context.
2. Choose route:
   • If inbound includes an image attachment path (QR image expected), call decode route.
   • Otherwise treat user text as arbitrary string and call process route.
3. Execute request with scripts/route_whatsapp.sh.
4. Return stdout from the script directly to the user.
5. If the endpoint returns an error or invalid JSON, return a short error summary and include raw response body.

Commands

Run from workspace root:

# Text -> /process
bash skills/whatsapp-local-router/scripts/route_whatsapp.sh process "<any text>"

# Image -> /decode-qr
bash skills/whatsapp-local-router/scripts/route_whatsapp.sh decode "/path/to/image.png"

Routing Rules

• Preserve text exactly; do not sanitize, trim, or reinterpret symbols.
• Use multipart field name image for QR decode uploads.
• Timeout requests after 20 seconds.
• If both text and image are present, prioritize image decode unless user explicitly asks to process text.
• Keep response concise: send backend JSON as-is.
