With over 13,700 skills on ClawHub and a documented history of malicious entries — 824 flagged by Koi Security’s expanded audit, 373 removed from curated lists, and the ClawHavoc campaign that planted crypto-stealing malware across hundreds of trading-themed skills — trusting your agent’s skill stack without verification is a gamble most teams can no longer afford. The good news: a new generation of security audit skills has arrived on ClawHub itself, letting your agent inspect its own tooling before anything touches production data.
Here are five security-focused skills worth installing today.
1. ClawSec Suite: The All-in-One Security Dashboard
Built by Prompt Security, ClawSec is not a single skill but a modular suite that bundles four capabilities into one install. The headline feature is soul-guardian, which watches your agent’s critical configuration files — SOUL.md, IDENTITY.md, and any custom instruction files — for unauthorized changes. It computes SHA-256 checksums on a schedule and auto-restores tampered files from a signed baseline. Drift detection for agent identity files is the kind of defense that sounds paranoid until you remember that prompt injection via modified config is one of the most common attack vectors in the wild.
The suite also includes clawsec-feed, which polls NIST’s National Vulnerability Database for CVEs affecting OpenClaw and NanoClaw, filtering by exploitability rather than just raw CVSS score. The optional openclaw-audit-watchdog runs daily automated audits with email reporting, and clawtributor lets you opt into community-reported threat intelligence.

2. Aegis-Audit: Deep Behavioral Analysis for Skills and MCP Tools
Aegis-audit takes a different approach from ClawSec’s runtime monitoring: it performs deep static analysis of skill source code before you install anything. Under the hood it combines AST parsing with Semgrep and 15 specialized scanners to produce CWE-mapped, OWASP-tagged reports with a 0–100 risk score. If a skill is reading environment variables it shouldn’t touch, making network calls to unexpected endpoints, or using dynamic code execution patterns common in supply chain attacks, aegis-audit will flag it.
What makes it especially useful is its cryptographic lockfile feature: after a clean audit, it generates an Ed25519-signed lockfile that acts as a tamper-detection seal. If the skill code changes after your audit — say, a maintainer pushes a compromised update — the signature check fails on next verification. This is the kind of supply chain hardening that enterprises have long demanded from package managers, now applied to the agent skill ecosystem.

3. Aegis-Shield: Real-Time Prompt Injection Defense
From the same Aegis family, aegis-shield operates at runtime rather than audit time. It screens untrusted text flowing into your agent for prompt injection attempts and data exfiltration patterns. Think of it as a firewall layer that sits between your agent’s input channel and its reasoning engine.
If your agent processes user-submitted content, emails, support tickets, or any text from sources you don’t fully control, aegis-shield adds a meaningful layer of defense against the injection attacks that remain one of the hardest problems in agent security. It’s lightweight enough to run on every inbound message without noticeable latency.

While aegis-audit focuses on individual skills, arc-security-audit takes a holistic view and audits your entire skill stack as an interconnected system. This matters because many security issues only emerge at the interaction layer — skill A is safe in isolation, skill B is safe in isolation, but together they create an unintended data path that leaks credentials.
Arc maps the permissions, data flows, and network access patterns across all installed skills and produces a composite risk assessment. For teams running agents with ten or more skills — which is increasingly common in production deployments — this system-level view is essential. It catches the inter-skill vulnerabilities that per-skill audits miss.

Azhua sits at the decision point: should I install this skill or not? It combines reputation signals from ClawHub (download counts, maintainer history, update frequency) with automated code analysis to produce a trust verdict. Think of it as the skill equivalent of checking an npm package’s health score before adding it to your project.
Azhua is particularly handy for teams that want a lightweight gate in their workflow without running a full static analysis pipeline. Point it at a skill name, get a quick trust-or-don’t recommendation with the reasoning spelled out. It won’t replace a deep audit for high-stakes deployments, but it’s an excellent first filter that catches the obvious red flags — newly created accounts publishing finance-themed skills, code that shells out to curl on install, or skills that request permissions wildly disproportionate to their stated purpose.

There’s an obvious bootstrapping problem: how do you trust the security tools? A few things to look for. ClawSec is built by Prompt Security, a funded company with a public track record in AI security. Aegis-audit generates verifiable signed artifacts. All five skills listed here are included in the VoltAgent curated list, which filters out malicious and low-quality entries. And ClawHub’s own VirusTotal integration now scans every published skill automatically.
None of this makes the supply chain problem disappear. But running agents in production without any security vetting layer is increasingly untenable, and these five skills represent the best the community has built so far to close that gap.
