Security Analysis & Protection Expert
Expert in security analysis, reverse engineering, intrusion detection, and system hardening. Specializes in using tools like Ghidra, forensics utilities, and security monitoring to ensure system safety
Use for a full security audit — T3 verify gate (money, auth, user data, migrations), pre-launch check, or when the user asks to audit the codebase for vulnerabilities. For quick diff-scoped checks, prefer a host-provided security reviewer when available, otherwise apply this skill to the diff.
Audit and fix security vulnerabilities across web apps, APIs, databases, auth systems, and infrastructure. Use when asked to review security, fix vulnerabilities, implement auth, or harden a system.
Evidence-grounded threat modeling, vulnerability review, and secure implementation. Use for explicit security audits or primary risks involving authorization, untrusted input, external requests, parsers/uploads, secrets, sensitive data, isolation, or release integrity. Not for routine implementation or non-security red-teaming. Add `security-identity-access` for identity and tenant authorization.
Security patterns and frameworks. Use when reviewing code for vulnerabilities, designing authentication/authorization, writing IAM policies, handling secrets, or discussing threat models.
Use for authorized security assessment of REST, GraphQL, WebSocket, or SOAP APIs, including discovery, authentication, authorization, rate-limit, and CI/CD testing.
Use for authorized security assessment of LLM applications and AI agents, including prompt injection, tool abuse, RAG exposure, memory poisoning, and model supply-chain risks.
Audit a vibe-coded web app's security against a practical checklist — RLS/auth, exposed secrets, signups, storage, IDOR, webhooks, headers, XSS. Tuned for React/Vite + Supabase on Netlify/Vercel/Cloudflare, with adaptations for Firebase and custom Node/Next APIs. Use whenever asked to do a security review/audit, check for vulnerabilities, find exposed secrets/keys, verify RLS or auth, harden an app before launch, or when the user types /security. Supports `/security --fix` (apply safe fixes on a branch) and `/security --grep` (offline CI-friendly scan only).
Audits a project's dependency and infrastructure security — runs composer/npm audit, checks CMS/framework security advisories, reviews the Docker setup, ranks every finding by exploitable criticality, and either applies safe fixes or gives exact step-by-step remediation. Stack-agnostic: pulls stack-specific advisory checks (e.g. Drupal SAs) from the loaded stack/ resource. Use when the user asks for a security audit, a CVE/vulnerability check, a dependency-security pass, or invokes /gm:security.
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.
