Performs comprehensive OWASP Top 10:2025 security vulnerability analysis on any codebase. Use this skill whenever the user asks to: review code for security, perform a security audit, scan for vulnerabilities, find security issues, improve application security, check for OWASP compliance, do a penetration test review, assess security posture, look for security flaws, scan for security risks, harden an application, or check code for exploits. Also trigger when the user mentions OWASP, CVEs, CWEs, security hardening, vulnerability assessment, or asks for a security report — even if they don't explicitly say "security scan." This skill works on any codebase in any language (JavaScript, TypeScript, Python, Java, Go, Ruby, C#, PHP, etc.).

Use when reviewing code for vulnerabilities, implementing authentication or authorization, handling user input, storing sensitive data, or before any feature that touches security boundaries goes to production
Use when the user asks for a deep, exhaustive, multi-pass, or variance-reducing repository-wide or scoped-path Codex Security scan. Run repeated independent Standard scans with the Codex Security deep-scan tool. Do not use for PRs, commits, branch diffs, or working-tree diffs.

Take a privately reported vulnerability through this repo's security advisory flow — board it, verify who owns the code path, accept or reject, fix it in the private fork, ship to every affected release line, publish, then turn the card into public tracking. Use when a vulnerability is reported privately; when deciding whether an advisory is ours to fix; when looking up or creating its private fork; when answering a reporter; or when a GHSA-titled board card needs handling.

Deep-dive security audit of a technical architecture diagram. Focused exclusively on authentication, authorization, credential protection, network boundaries, and data classification. Does NOT score overall quality — produces a prioritized security finding list. Use after arch-validate when you want a security specialist's deep cut.

Review application source code for broken authorization — IDOR / Broken Object Level Authorization (OWASP API1), Broken Function Level Authorization (API5), mass assignment (API3), multi-tenant isolation gaps, and privilege escalation. Reads routes, controllers, resolvers, and data models offline and reports the missing ownership/role check at file:line with a framework-correct fix. No running app, no credentials, no tools. Trigger when reviewing endpoints/handlers, auditing a PR diff that adds or changes routes, hardening a multi-tenant SaaS, or when the user asks "is this endpoint authorized?", "can a user access another user's data?", "IDOR", "BOLA", or "broken access control".

Audit Infrastructure-as-Code for security misconfigurations before it ships — Terraform (.tf/.tfvars/.hcl), CloudFormation/SAM (YAML/JSON), Kubernetes & Helm manifests, and Docker / Docker Compose. Reads the IaC offline and reports each misconfiguration at file:line with a severity (P0–P3) and a corrected snippet. A dependency-free scanner does the high-recall first pass; the model adds blast-radius and cross-resource judgment. No cloud credentials, no terraform apply, no pip install. Trigger when reviewing a Terraform plan before apply, auditing K8s/Helm manifests or a Dockerfile before deploy, checking CloudFormation for public S3 buckets or open security groups, doing a pre-deployment or compliance (SOC-2 / PCI-DSS / ISO-27001) security review, or when the user asks "audit this Terraform", "is this S3 bucket public?", "is this security group open to the internet?", "is this container running as root?", "what's the blast radius if this infra is wrong?", or "run an IaC security scan".

Guide authorized external penetration testing from recon through validation and scoped exploitation using free and open-source tools. Use for domain/IP attack surface mapping, subdomain discovery, nmap/httpx/nuclei/ffuf workflows, web app testing, SIP/NAS checks, Burp/ZAP validation, PoC documentation, and pentest reporting without commercial APIs.

Use when hardening APIs: HTTPS, HMAC 签名, timestamp+nonce 防重放, CORS, 脱敏, JWT none 算法, 密钥不进 URL. For SQL injection and resource 越权 WHERE, use backend-safe-check.
Security scan workflow — dependency audit, OWASP checklist, secrets scan, vulnerability report. Applies software-engineer role with security focus. Use standalone or as part of code review.
Scan the codebase for security vulnerabilities based on the OWASP Top 10. Use when the user asks to audit security, find vulnerabilities, check for security issues, or says "security scan", "audit this", "find security bugs".
A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
How do I use one I find here?
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
What do the warnings mean?
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Which skills worked for people?
Open a skill to see its discussion. Reports from people and their agents are coming.
