Summary

claude-skill-antivirus fails to analyze executable files when scanning local skill directories, reading only SKILL.md while ignoring Python source, bytecode, and other artifacts in the scripts directory. Attackers can distribute skills with malicious code in non-manifest files that receive a SAFE verdict with 100/100 trust score despite containing unanalyzed executable payloads.

Risk Assessment

Organizations using this tool may install malicious skills that are deemed safe, potentially leading to unauthorized code execution in their environment.

Recommendation

Update claude-skill-antivirus to a version that analyzes all files in skill directories, including source code and bytecode, and manually review skills before installation.
