About Security & Auditing
The best agent skills for security and auditing in 2026 pair Claude Code's built-in `security-review` Skill with scanner-backed MCP servers — Snyk, GitHub Advanced Security, AWS — giving the agent live vulnerability data alongside static analysis that catches injection patterns, auth bypass, race conditions, and the OWASP Top 10. Security & auditing Skills equip agents to find the vulnerabilities a human reviewer would miss in a hurried scan — and just as importantly, to document and triage them clearly. The category covers static analysis, dependency vulnerability scanning, Kubernetes hardening, IaC misconfiguration audits, secret-scanning, threat modeling, pentest tooling, and the security-review Skill that runs a structured pre-merge sweep on the current diff.
Common workflows include screening a PR for injection patterns, scanning a new repo for hardcoded credentials, generating a STRIDE threat model from an architecture diagram, hardening a Helm chart, auditing IAM policies for excessive permissions, and producing a findings report with severity ratings. Several Skills here pair with MCP servers — Snyk for SAST, GitHub Advanced Security for secret-scanning, AWS for IAM audits — so the agent has live access to scanner results, not just static rule lists.
Security engineers, platform teams, and CTOs at fast-shipping startups use these. Composite scoring weights provenance (Trail of Bits, GitHub Security Lab, recognized security orgs) heavily, plus install count from production teams. We do not rank tools intended for offensive use outside authorized contexts.

FAQ
Frequently asked
What does the security-review Skill check for?
Injection (SQL, command, XSS), auth bypass, race conditions, missing input validation, hardcoded secrets, insecure deserialization, SSRF, and the OWASP Top 10. It runs on the current branch's diff.
Are these Skills safe for offensive security work?
We rank Skills for defensive security, authorized pentesting, CTF, and security research. Skills focused on destructive techniques, DoS, mass targeting or detection evasion are not listed.
Do I need an MCP server for security Skills?
Some pair with Snyk, GitHub Advanced Security, AWS, or PagerDuty MCP servers for live data. Pure rule-based scanners run standalone inside the agent.
How do these Skills handle false positives?
The best Skills require a justification before flagging — they explain why a pattern matched and what the exploit would look like. This keeps the noise floor low enough to act on findings.
Can a Skill replace a real security audit?
No. It is a first pass that catches mechanical issues — the same things a senior engineer would catch with hours of careful reading. Real audits cover architecture, key management, and business logic that no Skill can model.
