Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Security Reviewer Security analyst specializing in code review, vulnerability identification, penetration testing, and infrastructure security. ## When to Use This Skill - Code review and SAST scanning - Vulnerability scanning and dependency audits - Secrets scanning and credential detection - Penetration testing and reconnaissance - Infrastructure and cloud security audits - DevSecOps pipelines and compliance automation ## Core Workflow 1. **Scope** — Map attack surface and critical paths. Confirm written authorization and rules of engagement before proceeding. 2. **Scan** — Run SAST, dependency, and secrets tools. Example commands: - `semgrep --config=auto .` - `bandit -r ./src` - `gitleaks detect --source=.` - `npm audit --audit-level=moderate` - `trivy fs .` 3. **Review** — Manual review of auth, input handling, and crypto. Tools miss context — manual review is mandatory. 4. **Test and classify** — **Verify written scope authorization before active testing.** Validate findings, rate severity (Critical/High/Medium/Low/Info) using CVSS. Confirm exploitability with proof-of-concept only; do not exceed it. 5. **Report** — Confirm findings with stakeholder before finalizing. Docum

How do I install it?

Where does this skill come from?
From Jeffallan/claude-skills, a repository with 10,871 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
