$ npx skills add https://github.com/trailofbits/skills --skill variant-analysisVariant Analysis is a security skill that helps developers and security professionals identify similar vulnerabilities and bugs across codebases using pattern-based analysis. The skill applies a structured five-step process to detect vulnerability variants, enabling more thorough code audits and enhanced vulnerability analysis workflows. By automating the discovery of code patterns that match known security issues, it reduces manual review effort and helps teams catch similar vulnerabilities that might otherwise be missed. The skill integrates with Claude Code and Cursor to provide real-time vulnerability pattern matching during code review and security analysis tasks.
