SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the critical security gap in the ClawHub ecosystem, where 36.8% of skills contain security flaws and malicious payloads can steal credentials or execute arbitrary code. It eliminates the risk of installing compromised skills by scanning for prompt injection, malicious code, suspicious downloads, and known threat indicators before they reach your workspace.

Core Features & Use Cases

  • Threat Detection: Scans for 8 categories of threats aligned with the Snyk ToxicSkills taxonomy, including prompt injection, malicious code execution, credential theft, and obfuscation techniques.
  • Context-Aware Analysis: Reduces false positives by approximately 80% by matching code patterns only in executable files such as js, py, and sh, while ignoring documentation.
  • Use Case: A developer installing third-party skills from ClawHub can run this scanner to verify each skill is safe, catching threats like the ClawHavoc campaign's fake prerequisites and Atomic Stealer malware before execution.

Quick Start

Use the guava-guard skill to scan the directory ~/.openclaw/workspace/skills/ for security threats and report any malicious patterns found.

Frequently Asked Questions about guava-guard

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I scan AgentSkills for malware before installing them?

You can scan AgentSkills for malware by running a static-analysis scanner on the skill directory to detect malicious code patterns, credential theft, and prompt injection. This prevents compromised skills from executing in your AI agent workspace.

What security threats should I look for when auditing third-party AI agent skills?

When auditing third-party AI agent skills, look for prompt injection, malicious code execution, credential theft, and obfuscation techniques. Detecting these threat categories prevents malicious payloads from compromising your workspace security.

Does the AgentSkill security scanner flag documentation files as malicious code?

No, an AgentSkill security scanner with context-aware analysis does not flag documentation as malicious. It restricts pattern matching to executable files like js, py, and sh, reducing false positives by about 80%.

Do I need external dependencies to run a prompt injection and malware detection scan on agent skills?

No, you do not need external dependencies to run a prompt injection and malware detection scan on agent skills. The scanner operates with zero external dependencies, using context-aware pattern matching to identify threats locally.

Can I scan a ClawHub registry to prevent fake prerequisites and credential theft?

Yes, you can scan a ClawHub registry to prevent fake prerequisites and credential theft. Auditing skill directories verifies each third-party skill is safe, catching threats like fake prerequisites and credential-stealing malware before execution.
