Why we included this project

Agent skills run with implicit trust and barely any vetting, yet most people pull them straight from a repo or URL. SkillSpector answers the practical question of whether a skill is safe to install by scanning Git repos, zip files, directories, or a single file before you load it into Claude Code, Codex, or an MCP server. Its two-stage pipeline does a fast static pass that matches 68 vulnerability patterns across 17 categories, from prompt injection and data exfiltration to privilege escalation and supply chain risks, then optionally layers on an LLM semantic check for trickier cases. Live lookups against OSV.dev pull current CVE data, and a risk score from 0 to 100 with baseline suppression means re-scans surface only new issues rather than known ones. For teams putting agent workflows into production, it is a practical pre-install gate that also feeds into the NVIDIA Verified Skills pipeline.
