security-audit

PostHog/posthog/.agents/skills/security-audit/SKILL.md

Focused security audit of code, calibrated to surface real exploitable bugs and suppress theoretical findings. Use when the user asks to "audit", "security-audit", "find vulnerabilities", "check for IDOR/SSRF/XSS/injection", or wants a security review of a file, directory, branch diff, or PR. Covers access control, injection, auth/secrets, sensitive data, business logic, web boundary, and AI agent/LLM trifecta risks. Produces calibrated findings with data flow, exploit request, fix, and confidence — no theoretical or defense-in-depth nits.

arcasilesgroupSkill

ai-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.

Use for security questions, focused reviews, vulnerability research, security audits, or pen tests.

security-audit

rommapp/romm/.claude/skills/security-audit/SKILL.md

Audit a diff (a release tag range or a PR branch) for anything malicious or a serious security regression before shipping/merging. Use when asked to "check this release", "make sure nothing malicious slipped in", "security review this PR", or vet upstream/contributor changes. Covers supply chain, egress/exfiltration, auth/injection/traversal, CI/infra, and commit provenance, with a fast direct pass plus fanned-out deep review. Trigger on any "is this change safe?" request over a diff.

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?".

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).
