Cybersecurity Skills for AI Agents
A collection of cybersecurity skills for AI coding agents. The AI does the heavy lifting; you bring the context about your stack and your priorities.
Built to be useful at every experience level:
- Security engineers and pentesters running formal audits — concrete grep patterns, OWASP / NIST / ATT&CK alignment, report templates that pass auditor review
- Developers shipping safer code without a dedicated security team to lean on — security work that fits into a normal sprint, plain-English explanations of why each finding matters
- Founders, ops folks, and small-team operators securing a stack they can't afford a CISO for — guided, opinionated playbooks for the most common security work, with the audit skill explaining what it found and why
- Red / blue / purple teams running real engagements — offensive recon, web pentest, threat hunting, detection engineering, SOC operations
You do not need to be a security expert to use these skills. The skills are written so the AI agent can run them end-to-end and explain the findings in language any technical reader can follow. If you can describe what you have and what you want to know about it, the agent can do the work.
Skills are authored as Claude Code SKILL.md files (the canonical format) and built into adapters for Cursor and Codex. Installable via npx skills or the Claude Code plugin marketplace.
Built by Bri Russell. I run real audits with these skills, then bring the gaps I find back into the skill itself — so each version is a little less opinion and a little more evidence.
Contributions welcome! Field feedback is the most valuable contribution — whether you're a security engineer who hit a gap during an audit, a developer whose AI agent missed something obvious, or a founder who used a skill and got an answer that wasn't quite right. Open a PR or open an issue — every level of expertise produces useful signal.
Where to start
Not every skill is for every user on day one. A good starting point by context:
- Not sure? Ask for
security-start (or just say "where do I start with security?"). It asks two or three questions and picks the skill.
- Reviewing your own code or product: start with
owasp-audit for the source-code sweep, then api-audit if you have API endpoints, then dependency-audit for the CVE pass
- A CVE wave just dropped and you run many apps:
patch-sweep to work out which apps are affected and ship fixes across the fleet, with dependency-audit for each project
- Want deterministic scanners in CI instead of asking an agent to "hack" your app:
scanner-pipeline picks the tools per layer, wires them into CI, and routes findings to finding-triage
- Securing cloud / infrastructure: start with
cloud-audit (AWS / GCP / Azure misconfig), then iam-audit if you manage identities, then container-audit if you run Docker / Kubernetes
- Responding to "something happened":
incident-triage for the immediate response, disk-forensics if you need to analyze a system afterward, malware-triage for a suspicious file someone found, security-comms to draft the stakeholder / customer communications
- No SIEM, no security staff, but you have logs:
log-watch sets up a scheduled agent that reads the logs you already have (Vercel, Heroku, Sentry, Supabase, Stripe, CloudTrail, GitHub) and pages someone when it matters
- You are the security team (founder / solo operator):
personal-opsec audits your own accounts, devices and AI-agent setup first — the person holding the keys is usually the softest target
- Building a security program from scratch:
csf-mapping for the governance frame, threat-modeling before new features, breach-patterns to learn from public incidents
- Working under a specific regulation:
privacy-engineering for GDPR / CCPA / similar privacy laws, hipaa-audit for ePHI, pci-audit for payment cards, control-audit for SOC 2, ISO 27001 or FedRAMP audit readiness, ai-risk-management for AI features
- Running AI coding agents with skills, plugins, or MCP servers:
agent-supply-chain-audit before you install or trust them — including this catalog
The offensive skills (recon, osint-recon, web-pentest, red-team-engagement) require explicit authorization for the target and assume more security context. They open with an authorization check and will refuse anything ambiguous. red-team-engagement in particular carries the strongest refusal posture in the catalog and will refuse to plan anything against systems the user cannot demonstrate authorization for.
What are Skills?
Skills are markdown files that give AI agents specialized knowledge and workflows for specific tasks. Drop them into your project and your agent recognizes when you're working on a security task and applies the right methodology — OWASP categories, NIST IR steps, MITRE ATT&CK references, the actual grep patterns that surface the bug.
