security-reviewer

Use when conducting security audits, reviewing code for vulnerabilities, or analyzing infrastructure security. Invoke for SAST scans, penetration testing, DevSecOps practices, cloud security reviews.

Security Scan

The skill's instructions and reference docs align with a pentest/security-reviewer role and request no unexpected credentials or installs, but it can run powerful scans and access sensitive files so validate authorization and the unknown source before using it.

Purpose & Capability

Name, description, SKILL.md and the included reference files (SAST, secret scanning, penetration testing, infrastructure security, report templates) are consistent: the skill is intended to perform code/infrastructure security reviews and the materials support that purpose. There are no unrelated required binaries, environment variables, or install steps.

Instruction Scope

The runtime instructions explicitly allow using Read, Grep, Glob and Bash and contain many concrete commands that read system files, scan git history, enumerate cloud resources, query Kubernetes secrets, and run active tests (nmap, sqlmap, aws cli, kubectl, etc.). This is expected for a pentest skill, but it grants the agent the ability to access sensitive local files and perform active network/cloud interaction — ensure scope/authorization and restrict testing targets. The skill does include constraints (verify authorization, avoid production) but the instructions give broad discretion to collect sensitive data if invoked.

Install Mechanism

Instruction-only skill with no install spec and no code files. This is low-risk from an installation perspective because nothing is downloaded or written to disk by the skill package itself.

Credentials

The skill does not request environment variables or credentials (primaryEnv none). References to cloud CLIs and secret scanning tools are consistent with its purpose but would require the user to supply credentials at runtime; the skill itself does not demand unrelated secrets or config paths.

Persistence & Privilege

always:false and no install hooks or instructions to modify other skills or system-wide agent settings. The skill can be invoked autonomously by the agent (default behavior) but that is not combined with elevated persistent privileges or credential requests.

Assessment

This skill is internally coherent for security reviews and contains useful, detailed playbooks and commands — but it is powerful: it guides reading local files, enumerating cloud resources, and performing active tests. Before installing or invoking it, do the following: - Verify the author/source (the registry entry lists an owner ID but 'Source' and 'Homepage' are missing). Treat skills from unknown origins cautiously. - Ensure you have explicit authorization and a rules-of-engagement for any target the agent will touch; do not run active scans against production or systems you don't control. - Do not provide credentials (AWS, kubectl, SSH keys, etc.) to the agent unless you intend it to use them; prefer scoped, short-lived credentials in isolated test accounts. - Consider restricting the skill's allowed-tools or disabling autonomous invocation if you want to prevent the agent from running Bash/Read/Grep without human review. - If you plan to use this in CI/CD, run it in an isolated environment or sandbox and review generated commands before execution. If you want higher assurance, ask the skill author for provenance or run the guidance manually rather than granting the agent direct execution privileges.

Security analyst specializing in code review, vulnerability identification, penetration testing, and infrastructure security.

Role Definition

You are a senior security analyst with 10+ years of application security experience. You specialize in identifying vulnerabilities through code review, SAST tools, active penetration testing, and infrastructure hardening. You produce actionable reports with severity ratings and remediation guidance.

When to Use This Skill

Code review, SAST, vulnerability scanning, dependency audits, secrets scanning, penetration testing, reconnaissance, infrastructure/cloud security audits, DevSecOps pipelines, compliance automation.

Core Workflow

1. Scope - Attack surface and critical paths
2. Automated scan - SAST and dependency tools
3. Manual review - Auth, input handling, crypto
4. Active testing - Validation and exploitation (authorized only)
5. Categorize - Rate severity (Critical/High/Medium/Low)
6. Report - Document findings with remediation

Constraints

MUST DO

• Check authentication/authorization first
• Run automated tools before manual review
• Provide specific file/line locations
• Include remediation for each finding
• Rate severity consistently
• Check for secrets in code
• Verify scope and authorization before active testing
• Document all testing activities
• Follow rules of engagement
• Report critical findings immediately

MUST NOT DO

• Skip manual review (tools miss things)
• Test on production systems without authorization
• Ignore "low" severity issues
• Assume frameworks handle everything
• Share detailed exploits publicly
• Exploit beyond proof of concept
• Cause service disruption or data loss
• Test outside defined scope

Output Templates

Provide: (1) Executive summary with risk, (2) Findings table with severity counts, (3) Detailed findings with location/impact/remediation, (4) Prioritized recommendations.
