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.
Use for authorized email security review including phishing analysis, header authentication (SPF/DKIM/DMARC), BEC patterns, and mailbox token abuse research.

Use this skill when adding authentication, handling user input, working with secrets, creating API endpoints, or implementing payment/sensitive features. Provides comprehensive security checklist and patterns.
Audits code for exploitable vulnerabilities with independent validation and schema-checked findings. Trigger: milestone security audits, "security review", "find security bugs", or "pen-test". Reports real impact, not theory. Not for runtime diagnosis (/ai-debug) or diff correctness (/ai-verify).

Run a Snyk security scan of the repo (frontend npm deps, backend pip deps, Dockerfile/base image, and Snyk Code SAST), triage findings, and remediate the real ones with verified fixes. Use for "scan with Snyk", "resolve the security issues", dependency-CVE cleanup, or a pre-release security pass.
SECURE BY DEFAULT. When building login, API routes, file uploads, database queries, payments, user content, admin panels, webhooks, forms, password reset, OAuth, or any web feature — auto-detect what the user is building and inject the correct security patterns BEFORE it ships. Prevents env leaks, XSS, SQLi, IDOR, CSRF, SSRF, path traversal, mass assignment. Frameworks: Next.js, React, Express, Remix, SvelteKit.

Security guidance and vulnerability review for codebases, APIs, services, CLI tools, libraries, and daemons. Use for security questions, focused reviews, vulnerability research, security audits, or pen tests. Run the complete workflow only for explicit codebase audit or pen-test requests, full/comprehensive/end-to-end reviews, or requested report artifacts.
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.
Scan your Claude Code configuration (.claude/ directory) for security vulnerabilities, misconfigurations, and injection risks using AgentShield. Checks CLAUDE.md, settings.json, MCP servers, hooks, and agent definitions.
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.
