arcasilesgroupSkillai-security
arcasilesgroup/ai-engineering/skills/ai-security/SKILL.md
Six-phase security audit of a codebase — web apps, APIs, services, CLI tools, libraries, and daemons — with adversarial validation: the agent that verifies a finding is never the one that found it. Recon, parallel hunting across 8 attack classes, validation, reporting, schema-validated findings.json, and independent verification. Only exploitable issues with real impact are reported — never theoretical concerns or industry-standard behavior. Use when a milestone declares a security audit, when findings must be validated adversarially, or for trigger phrases "security review", "audit for vulnerabilities", "find security bugs", and "pen-test the code". Not for diagnosing a runtime failure — use /ai-debug. Not for judging a diff for correctness — use /ai-verify.

raroqueSkillvibe-security
raroque/vibe-security-skill/vibe-security/SKILL.md
Audits codebases for common security vulnerabilities that AI coding assistants introduce in "vibe-coded" applications. Checks for exposed API keys, broken access control (Supabase RLS, Firebase rules), missing auth validation, client-side trust issues, insecure payment flows, and more. Use this skill whenever the user asks about security, wants a code review, mentions "vibe coding", or when you're writing or reviewing code that handles authentication, payments, database access, API keys, secrets, or user data — even if they don't explicitly mention security. Also trigger when the user says things like "is this safe?", "check my code", "audit this", "review for vulnerabilities", or "can someone hack this?".

GitHubSkillsecurity-review
github/awesome-copilot/skills/security-review/SKILL.md
AI-powered codebase security scanner that reasons about code like a security researcher — tracing data flows, understanding component interactions, and catching vulnerabilities that pattern-matching tools miss. Use this skill when asked to scan code for security vulnerabilities, find bugs, check for SQL injection, XSS, command injection, exposed API keys, hardcoded secrets, insecure dependencies, access control issues, or any request like "is my code secure?", "review for security issues", "audit this codebase", or "check for vulnerabilities". Covers injection flaws, authentication and access control bugs, secrets exposure, weak cryptography, insecure dependencies, and business logic issues across JavaScript, TypeScript, Python, Java, PHP, Go, Ruby, and Rust.
AnthropicSkillclaude-security
anthropics/claude-plugins-official/plugins/claude-security/skills/claude-security/SKILL.md
Claude Security: scan the codebase (the whole repository or a scoped part of it), scan changes (this branch's or a pull request's diff, or one commit), or suggest patches (findings turned into targeted patch files, each verified by a panel of agents, that you apply when you choose). Use when the user asks to scan, audit or check code with Claude Security, to scan their changes with Claude Security, or to fix or patch Claude Security findings.

RTFM-IT-Services-LLCSkillmsp-security
RTFM-IT-Services-LLC/msp-claude-skills/skills/msp-security/SKILL.md
Use this skill for security standards at your managed IT services (MSP) business, in both directions: the baseline every managed client must meet (MFA, endpoint protection, email security, backups, admin access, offboarding) and how the MSP secures itself (RMM hardening, the credential vault, admin separation, partner-delegated admin access into client tenants, our own devices). Trigger on "security baseline", "security standard", "harden this tenant", "is this client secure enough", "security assessment", "cyber insurance questionnaire", "can we say we're compliant", HIPAA, FTC Safeguards, WISP, CMMC, PCI, CIS Controls, "lock down our RMM", or any question about what controls a client or our MSP should have. msp-helpdesk owns incident response; msp-maintenance owns patch and backup cadence; this skill owns the standard they deliver against. Apply alongside msp-onboarding, msp-qbr, msp-legal, msp-pricing, msp-client-comms, and msp-sales.

About skills
What is a Claude skill?
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.
