What it does

“Review a pull request, commit, branch diff, or working-tree patch for security vulnerabilities.”
The author's description, from SKILL.md

Generated summary from the skill's own text

This skill reviews code changes in pull requests, commits, or branches for security vulnerabilities by analyzing diffs, modeling threats, discovering candidates, validating findings, and generating security reports with coverage analysis.

When to use it

  • Scanning pull requests or commits for security issues before merging
  • Reviewing code diffs for threat modeling and vulnerability discovery
  • Auditing working-tree changes or local patches for security risks
  • Generating security reports with SARIF output for compliance

When not to

  • Performing full repository audits or expanding into unrelated code areas
  • Automatic remediation without user approval or manual review
  • Scanning when Git or local baseline state cannot be precisely determined
