Abstract
This empirical study analyzes security vulnerabilities in AI-agent skills at scale. It collects skills from major marketplaces, applies SkillScan to detect vulnerable and malicious patterns, and builds a taxonomy spanning prompt injection, data exfiltration, privilege escalation, and supply-chain risks.
