NanoClaw is an AI assistant that runs agents inside separate Linux containers, isolating their files and execution environments. People use it to connect agents to messaging services and run assistants with memory and scheduled jobs. The catalogue contains skills and instructions for extending or operating NanoClaw.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 11 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.06180 |
| Opus 5 | $0.00016 | $0.03090 |
| Sonnet 5 | $0.00006 | $0.01236 |
| Haiku 4.5 | $0.00003 | $0.00618 |
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 13d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
rm -rf store/auth/ && pnpm exec tsx setup/index.ts --step whatsapp-auth -- --method qr How it starts
The opening of the file, as written. The whole thing — 525 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add WhatsApp Channel
Adds WhatsApp support via the native Baileys adapter — a direct WhatsApp Web
connection, no Chat SDK bridge. NanoClaw doesn't ship channels in trunk — this
skill copies the WhatsApp 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.
Number safety check (required)
Complete this check before running any install or authentication command. If the user already said they want to use their shared, personal, main, existing, or everyday WhatsApp number, treat it as a shared number and show the warning immediately. Do not ask the number-type question again.
Otherwise, ask which WhatsApp number NanoClaw will use:
Which WhatsApp number will NanoClaw use? `dedicated` (recommended) — a separate number used only for NanoClaw (spare SIM, eSIM, or old phone). `shared` — your existing everyday / personal WhatsApp number.
If the answer is shared, show this warning — tell the user:
⚠️ Risk to your WhatsApp account
Connecting your shared or personal number could cause WhatsApp to temporarily suspend or permanently ban that number. You could lose access to the WhatsApp account, chats, and groups you rely on.
We strongly recommend using a separate, dedicated number for NanoClaw.
On your personal number, the agent lives only in your "You" / self-chat. Messages other people send you are ignored entirely — never read, never answered, never flagged for approval. Nobody else can talk to the agent.
If you want the agent reachable as its own contact, consider:
• Telegram — a bot takes ~2 minutes to set up
• a dedicated WhatsApp number — spare SIM, eSIM, or old phone
• /add-whatsapp-cloud — the official Meta Business API
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 13d ago First seen · 525 lines · 32 tokens per session scan C 4cf4fe64fb25
add-whatsapp is a skill published in the GitHub repository nanocoai/nanoclaw (30,745 stars, last pushed today), licensed MIT. It adds 32 tokens to every session and 6,180 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
