Repello AI SkillCheck is a tool for scanning and cataloging AI agent skills (also referred to as plugins or tools used by AI systems). It maintains a browsable skill library where users can explore skills that have been scanned by SkillCheck. Users can upload skills for scanning, and results are organized by severity. The library supports sorting by newest entries, number of downloads, and name, allowing users to navigate and review scanned skills in a structured manner. The tool is oriented toward assessing the security posture of AI agent skills, enabling users to identify potential risks associated with specific skills before or during deployment.
