Key point
NVIDIA has released SkillSpector, a security scanner that detects vulnerabilities and malicious patterns in AI agent skills.
Details
AI agent skills used in Claude Code, Gemini CLI, and others operate on a trust-based model and can be vulnerable to security issues. Research found that 26.1% of skills contain vulnerabilities, and 5.2% were found to have malicious intent.
SkillSpector verifies the security of skills before installation to prevent these risks. Its main features are as follows.
- Support for various input formats: Can scan Git repositories, URLs, zip files, directories, and single files
- Broad detection scope: Detects 64 vulnerability patterns across 16 categories, including prompt injection, data exfiltration, privilege escalation, and supply chain attacks
- Two-stage analysis approach: Combines fast Static Analysis with optional LLM-based Semantic Evaluation
- Real-time vulnerability lookup: Real-time CVE data lookup via OSV.dev with offline fallback support
- Various output formats: Supports Terminal, JSON, Markdown, and SARIF, and provides a risk score between 0 and 100
Users can configure various LLM endpoints such as OpenAI, Anthropic, and NVIDIA Inference API to perform more precise semantic analysis.
