What is clawsec-nanoclaw?

A security-checking skill for NanoClaw skills and dependencies. Security advisories are notices about known vulnerabilities that may affect software.

Use it before installing a skill, during security audits, after security notifications, or when investigating suspicious behavior in the bot.

It helps identify vulnerable skills before installation and alerts users when installed skills match known security issues.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code, Codex.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00035	$0.02172
Opus 5	$0.00017	$0.01086
Sonnet 5	$0.00007	$0.00434
Haiku 4.5	$0.00003	$0.00217

Measured 9d ago against content hash c735d0249dd9, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade B, and why

clawsec-nanoclaw scanned grade B with 2 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 9d ago.

The scan reads SKILL.md. This mod also ships 14 executable files (guardian/integrity-monitor.ts, host-services/advisory-cache.ts, host-services/integrity-handler.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

trap 'rm -rf "$TMP_DIR"' EXIT

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

ClawSec for NanoClaw

Security advisory monitoring that protects your WhatsApp bot from known vulnerabilities in skills and dependencies.

Overview

ClawSec provides MCP tools that check installed skills against a curated feed of security advisories. It prevents installation of vulnerable skills, includes exploitability context for triage, and alerts you to issues in existing ones.

Core principle: Check before you install. Monitor what's running.

When to Use

Use ClawSec tools when:

Installing a new skill (check safety first)
User asks "are my skills secure?"
Investigating suspicious behavior
Regular security audits
After receiving security notifications

Do NOT use for:

Code review (use other tools)
Performance issues (different concern)
General debugging

MCP Tools Available

Pre-Installation Check

// Before installing any skill
const safety = await tools.clawsec_check_skill_safety({
  skillName: 'new-skill',
  skillVersion: '1.0.0'  // optional
});

if (!safety.safe) {
  // Show user the risks before proceeding
  console.warn(`Security issues: ${safety.advisories.map(a => a.id)}`);
}

Security Audit

// Check all installed skills (defaults to ~/.Codex/skills in the container)
const result = await tools.clawsec_check_advisories({
  installRoot: '/home/node/.Codex/skills'  // optional
});

if (result.matches.some((m) =>
  m.advisory.severity === 'critical' || m.advisory.exploitability_score === 'high'
)) {
  // Alert user immediately
  console.error('Urgent advisories found!');
}

Browse Advisories

// List advisories with filters
const advisories = await tools.clawsec_list_advisories({
  severity: 'high',               // optional
  exploitabilityScore: 'high'     // optional
});

What ships with it

22 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.

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.

clawsec-nanoclaw is a skill published in the GitHub repository opencue/cuecards (5 stars, last pushed yesterday), licensed MIT. It adds 35 tokens to every session and 2,172 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
