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 A, and why

add-whatsapp-cloud scanned grade A with 0 findings 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 12d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Add WhatsApp Cloud API Channel

Connect NanoClaw to WhatsApp via the official Meta WhatsApp Business Cloud API. NanoClaw doesn't ship channels in trunk — this skill copies the WhatsApp Cloud adapter in from the channels branch.

The mechanical steps under Apply carry nc: directive fences: an agent reads the prose and applies them, and a parser can apply them deterministically from the same document. Every directive is idempotent, so the whole skill is safe to re-run; anything a parser can't apply falls back to the prose beside it.

Apply

1. Copy the adapter

Fetch the channels branch and copy the WhatsApp Cloud adapter into src/channels/ (overwrite — the branch is canonical):

src/channels/whatsapp-cloud.ts
src/channels/whatsapp-cloud-registration.test.ts

2. Register the adapter

Append the self-registration import to the channel barrel (skipped if the line is already present). This one line is the skill's only reach-in into core:

import './whatsapp-cloud.js';

3. Install the adapter package

Pinned to an exact version — the supply-chain policy rejects ranges and latest:

@chat-adapter/[email protected]

4. Build and validate

Build guards the typed createChatSdkBridge(...) core call and proves the dependency is installed — the import throws at evaluation if @chat-adapter/whatsapp is missing or the barrel drifts:

pnpm run build
pnpm exec vitest run src/channels/whatsapp-cloud-registration.test.ts

whatsapp-cloud-registration.test.ts imports the real channel barrel and asserts the registry contains whatsapp-cloud — it goes red if the import line is deleted or drifts, if the barrel fails to evaluate, or if @chat-adapter/whatsapp isn't installed (the import throws), so it also covers the dependency from step 3.

End-to-end message delivery against a real WhatsApp Business number is verified manually once the service is running — see Next Steps and the webhook setup below.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
