NVIDIA SkillSpector: scan agent skills for 71 vuln patterns before install
NVIDIA’s Apache-2.0 SkillSpector checks Claude Code, Codex, and Gemini skills (plus MCP) for prompt injection, exfil, supply-chain, and tool-poisoning risks—71 patterns across 17 categories, with optional LLM analysis and an MCP scan_skill install gate. A 31k-skill study found 26.1% vulnerable; install via uv tool install 'skillspector[mcp] @ git+https://github.com/NVIDIA/skillspector.git'.
