Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads security-auditor automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Security Auditor
Expert in identifying security vulnerabilities following OWASP Top 10 and security best practices.
When This Skill Activates
Activates when you:
- Request a security audit
- Mention "security" or "vulnerability"
- Need security review
- Ask about OWASP
OWASP Top 10:2025 Coverage
Use the current OWASP Top 10 as an awareness taxonomy, not as proof of complete security coverage. For verifiable application controls, map findings to the current OWASP ASVS or the project's required standard.
A01: Broken Access Control
- Verify authentication and object/function-level authorization on every sensitive path.
- Test tenant boundaries, IDOR/BOLA, role changes, and server-side URL fetch controls.
- SSRF is included in this 2025 category; validate destinations, schemes, redirects, and network egress.
A02: Security Misconfiguration
- Inspect debug flags, CORS, security headers, default accounts, cloud/IaC policy, and error exposure.
- Compare runtime configuration with hardened environment-specific defaults.
A03: Software Supply Chain Failures
- Review lockfiles, provenance, build workflows, mutable CI dependencies, update policy, and dependency risk.
- Distinguish a vulnerable package from compromised build or distribution infrastructure.
A04: Cryptographic Failures
- Check secret storage, transport encryption, key lifecycle, random generation, algorithms, and data-at-rest requirements.
- Flag hardcoded credentials, weak hashes, insecure modes, and missing certificate verification.
A05: Injection
- Trace untrusted data into SQL/NoSQL, shell, template, LDAP, expression, and browser execution sinks.
- Prefer parameterization and safe APIs; test encoding at the actual output context.
A06: Insecure Design
- Threat-model trust boundaries, abuse cases, rate limits, high-risk workflows, and failure recovery.
- Verify the design prevents unsafe states rather than relying only on downstream validation.
A07: Authentication Failures
- Review credential handling, MFA where risk warrants it, reset/recovery flows, session rotation, expiry, and brute-force defenses.
A08: Software or Data Integrity Failures
- Verify signatures, trusted update channels, deserialization boundaries, artifact integrity, and protection from unauthorized data changes.
A09: Security Logging and Alerting Failures
- Check that security-relevant events are logged without secrets, protected from tampering, monitored, and connected to actionable alerts.
A10: Mishandling of Exceptional Conditions
- Exercise malformed input, resource exhaustion, timeouts, partial failures, concurrency, and dependency outages.
- Look for fail-open behavior, swallowed errors, unsafe retries, inconsistent state, and missing rollback or reconciliation.

FAQ
What does the security-auditor skill do?
Security vulnerability expert covering OWASP Top 10 and common security issues. Use when conducting security audits or reviewing code for vulnerabilities.
How do I install security-auditor?
Run npx skills add https://github.com/zhaono1/agent-playbook --skill security-auditor in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/security-auditor/ (personal) or .claude/skills/security-auditor/ (project).
Which AI agents can use security-auditor?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is security-auditor safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains security-auditor?
It is published by zhaono1 in zhaono1/agent-playbook. It has 1,050 recorded installs.
More from zhaono1/agent-playbook
self-improving-agent
zhaono1/agent-playbook
Use after a failure, user correction, repeated workflow problem, or validated success reveals a reusable lesson. Captures bounded redacted candidates, runs executable behavior evals, and separates validation from application in durable guidance.
planning-with-files
zhaono1/agent-playbook
Uses persistent markdown files for general planning, progress tracking, and knowledge storage (Manus-style workflow). Use for multi-step tasks, research projects, or general organization WITHOUT mentioning PRD. For PRD-specific work, use prd-planner skill instead.
architecting-solutions
zhaono1/agent-playbook
Designs technical solutions and architecture. Use when user says "design solution", "architecture design", "technical design", or "方案设计" WITHOUT mentioning PRD. For PRD-specific work, use prd-planner skill instead.
skill-router
zhaono1/agent-playbook
Routes an agent request to the narrowest matching portable skill when the user asks which skill to use or needs help selecting one across supported hosts.
workflow-orchestrator
zhaono1/agent-playbook
Coordinates multi-skill workflows and records or runs follow-up actions when the host runtime supports them. Use when completing PRD creation, implementation, or any milestone that should be evaluated for additional skills.
prd-planner
zhaono1/agent-playbook
Creates PRDs using persistent file-based planning. Use when user explicitly says "PRD", "product requirements document", or "产品需求文档". Combines PRD methodology with planning-with-files to avoid context switching.

Also use when the user mentions 'alternative page,' 'vs page,' 'competitor comparison,' 'comparison page,' '[Product] vs [Product],' '[Product] alternative,' 'competitive landing pages,' 'how do we compare to X,' 'competitor teardown,' 'audit our competitor pages,' 'are our comparison pages out of date,' or 'competitive asset audit.' Use this for any content that positions your product against competitors. Covers four formats: singular alternative, plural alternatives, you vs competitor, and competitor vs competitor. For auditing existing claims (not researching competitors from scratch, which is competitor-profiling; not technical SEO on these pages, which is seo-audit), use the asset audit here. For internal battle cards and sales-specific competitor docs, see sales-enablement.
