security-audit

kubeshark/kubeshark/skills/security-audit/SKILL.md

Kubernetes network security audit skill powered by Kubeshark MCP. Use this skill whenever the user wants to audit a cluster for security threats, detect compromised workloads, find malicious traffic patterns, hunt for indicators of compromise (IOCs), check for data exfiltration, identify C2 (command and control) communication, detect cryptomining, find lateral movement, discover credential theft attempts, assess network security posture, or perform threat hunting in Kubernetes. Also trigger when the user mentions security audit, threat detection, compromise assessment, vulnerability scan, "is my cluster compromised", "find malicious traffic", "check for threats", DNS exfiltration, DNS tunneling, port scanning, IMDS access, reverse shell, crypto miner, MITRE ATT&CK, IOC detection, anomaly detection, suspicious traffic, rogue workloads, unauthorized access, or any request to evaluate cluster security through network traffic analysis.

heliomarpmSkill

sk-security

heliomarpm/skills/skills/sk-security/SKILL.md

Audita e projeta a segurança de aplicações: autenticação e sessão (OAuth com PKCE, OIDC, JWT), autorização por recurso (RBAC/ABAC, BOLA/IDOR), entrada e injeções, criptografia e segredos, dependências, cabeçalhos web, logs e privacidade, com checklist baseado no OWASP, achados com severidade e plano de remediação. Use sempre que o usuário pedir 'audite a segurança', 'isto é seguro?', 'revise a autenticação', 'proteja este endpoint', 'vazou um segredo', 'vulnerabilidades', 'OWASP', 'hash de senha', 'CSP' ou 'permissões', mesmo sem a palavra 'segurança'. NÃO use para desenhar contratos de API (isso é sk-api-design), infraestrutura e pipelines (isso é sk-devops) nem para revisar um diff em geral (isso é sk-code-review).

AnthropicSkill

claude-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.

security-setup

luongnv89/skills/skills/security-setup/SKILL.md

Install local-first security hardening: pre-commit secret detection, offline dependency scans, static analysis, reports, and gated free CI. Use when hardening repos or adding security hooks. Don't use for incident response or cloud security reviews.

raroqueReads credentialsSkill

vibe-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?".

Google CloudSkill

security-scan

GoogleCloudPlatform/cloud-solutions/projects/build-with-gemini-demo/build-with-antigravity/.agents/skills/security-scan/SKILL.md

Performs a security audit of the project source code and dependencies to identify vulnerabilities and recommend remediations. Use when scanning the codebase for security issues. Don't use for functional unit testing or style-only code formatting.

GitHubReads credentialsSkill

security-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.

RTFM-IT-Services-LLCSkill

msp-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.

langfuseSkill

security-review

langfuse/langfuse/.agents/skills/security-review/SKILL.md

Review Langfuse changes for SSRF, tenant isolation, secret handling, unsafe redirects or uploads, RBAC drift, and client telemetry privacy. Use when a design or change accepts URLs or host fields, handles secrets or cross-tenant data, makes outbound requests, adds an integration, follows redirects, widens permissions, or can send customer-controlled UI data through analytics, monitoring, or session replay.

Assigns severity and affected maintained branches, and routes to the next step. Use when the user says "does this need a CVE", "CVE or hardening", "triage this report", "is this a security issue", "classify this finding", or "how should we disclose this".
