Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

add-whatsapp scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Add WhatsApp Channel

This skill adds WhatsApp support to Breadbrich Engels. 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? (Digits only — country code followed by your 10-digit number, no + prefix, spaces, or dashes. Example: 14155551234 where 1 is the US country code and 4155551234 is the phone number.)

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:
