ESET AI Skills Checker is a free online tool that analyzes AI agent skill URLs in real time to detect signs of malicious activity before installation. AI agents rely on skills (plugins or extensions) to perform tasks. These skills are sourced from marketplaces and registries and can be updated frequently, potentially introducing hidden risks. This tool allows users to submit a skill URL and receive a rapid safety verdict. How it works: - The tool cross-references skill metadata, publisher reputation, dependency hints, and known threat indicators against continuously updated security intelligence. - It delivers one of four verdicts: Safe, Not Safe (link), Not Safe (skill), or Suspicious. Verdict definitions: - Safe: No signs of malicious behavior, phishing, suspicious install instructions, or high-risk trust signals detected. - Not Safe (link): The URL is flagged as unsafe, with potential exposure to malware, identity theft, or financial fraud. - Not Safe (skill): The skill is flagged as potentially containing risky instructions, malicious code, phishing tactics, or signs of tampering. - Suspicious: No obvious threats detected, but risk indicators are present; caution is advised. The tool is positioned as a pre-installation check for AI agent skills and is offered as a standalone free utility. It is separate from ESET's paid Home Security product line, though results pages promote ESET HOME Security for ongoing real-time protection.
