Reviewer notes

Reviewed review. These are observations, not a security certification.

4k stars, CC-BY-SA-4.0 license, maintained by Trail of Bits (premier security firm). 25 open issues — normal for an active org repo. Gold standard for security-focused Claude Code skills. Breadth is 3 because domain is specifically security/audit.

Trail of Bits is the most trusted maintainer profile in this batch. CC-BY-SA-4.0: permissive for use, requires attribution on redistribution. Skills are SKILL.md + Python scripts analyzing code files — no external network calls. Institutional-grade code quality.

2026-04-02: LIMITATION: Domain-specific to security/audit work — high confidence but limited applicability to non-security teams. CC-BY-SA-4.0 license requires attribution on redistribution.

Things to check

  • Requires familiarity with security concepts and the underlying tools (CodeQL, Semgrep, YARA); not a replacement for professional security audits. Effectiveness depends on Claude's code understanding and the quality of integrated rule definitions.
