Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

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.

daianepepes-labSkilldaianepepes-lab/claude-skills/security/SKILL.md
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.

n-n-codeSkilln-n-code/n-n-code-skills/.agents/skills/security/SKILL.md
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.

flywheel-productSkillflywheel-product/ai-build-skills/security/SKILL.md
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).

gingermindsReads credentialsSkillgingerminds/claude-skills/skills/security/SKILL.md
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.

Security Policy ## Reporting a Vulnerability If you discover a security vulnerability in this project, please report it responsibly. Do NOT open a public GitHub issue for security vulnerabilities. Open
Often used withcost-reduceralbert-dmscalability
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.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
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.
Open a skill to see its discussion. Reports from people and their agents are coming.
