OpenClaw Skills Are Powerful — But Deadly

Every skill your agent installs is untrusted code running with full access to your system. No sandbox. No review. No guardrails. Here's what's already happening in the wild.

CRITICAL

Remote Code Execution

SKILL.md

A single hidden comment in a SKILL.md file can wipe your entire filesystem and exfiltrate every secret — before your agent even finishes its first task.

HIGH

Silent Data Exfiltration

SKILL.md

Your API keys, database credentials, and cloud tokens — silently harvested and transmitted to attacker infrastructure. Zero logs. Zero alerts.

HIGH

Agent Hijacking

SKILL.md

Prompt injection turns your trusted agent into an attacker's puppet. It executes malicious payloads while reporting everything is fine.

1 in 12 community skills contain potentially malicious patterns. Your agents are installing them right now.

Two Layers of Protection

Static Analysis Catches What's Obvious. AI Catches What's Clever.

Static Scan

Lightning fast

Pattern-matching engine that instantly flags known threats — embedded shell commands, suspicious URLs, dangerous permissions, and hidden code blocks.

  • 100+ regex pattern rules
  • URL reputation checking
  • Permission analysis
  • Embedded code detection

AI Deep Scan

Your security agent

Goes beyond patterns — understands what a skill is actually trying to do. If something looks suspicious, it catches it, explains it, and keeps you safe.

  • Understands attacker intent, not just patterns
  • Detects multi-step obfuscated exploits
  • Catches social engineering & prompt injection
  • Explains every threat in plain language

Everything you need to know about ClawGuard.

ClawGuard is a security scanner built for the OpenClaw ecosystem. It analyzes AI agent skill files (SKILL.md) to detect hidden threats like prompt injection, secret exfiltration, and unauthorized code execution — before those skills ever run on your system.

ClawGuard uses two layers of analysis. The Static Scan performs fast, rule-based pattern matching to catch known attack signatures. The AI Deep Scan uses a language model to understand the intent behind instructions — detecting obfuscated, social-engineered, or novel threats that static rules miss. Together, they give you both speed and depth.

No. The Free plan gives you 1 static scan per day with no payment required at all. For paid plans, all payments are made in USDC on Solana — no credit card, no bank account, no KYC. Just connect your wallet and top up credits instantly.

We offer four plans: Free (1 static scan/day, no signup needed), Starter ($5/mo, 100 credits, static + AI deep scans), Pro ($15/mo, 300 credits, API access, webhooks, priority queue), and Business ($39/mo, 800 credits, team seats, bulk scanning, custom rules, dedicated support). Paid plans also support flexible top-ups — top-up credits never expire.

ClawGuard detects prompt injection, secret/key exfiltration, hidden code execution (e.g., curl piped to bash), malicious domain references, excessive permission requests, obfuscated payloads, data harvesting patterns, unauthorized network access, and social engineering tactics embedded in skill instructions.

Your Agents Trust Every Skill They Run. Shouldn't You Verify Them First?
