Ln 621 Security Auditor

levnikolaevich/claude-code-skills
338 installs533 stars
Summary

This is a specialized L3 worker that scans your codebase for security vulnerabilities like hardcoded secrets, SQL injection, XSS, insecure dependencies, and missing input validation. It returns structured findings with severity levels, locations, and remediation recommendations, then calculates a compliance score out of 10. Part of a larger worker coordination system based on the references to audit contracts and MCP integration patterns. If you're running security audits as part of an automated review pipeline, this handles the scanning grunt work and reports back in a structured format. With 337 installs and 480 GitHub stars, it's clearly being used in production workflows already.
