Use when writing or reviewing PHP that prints data into HTML (render callbacks, server-rendered markup), accepts input, or exposes data through a REST route or other API.
Use for authorized security assessment of REST, GraphQL, WebSocket, or SOAP APIs, including discovery, authentication, authorization, rate-limit, and CI/CD testing.
Use for authorized security assessment of LLM applications and AI agents, including prompt injection, tool abuse, RAG exposure, memory poisoning, and model supply-chain risks.
Find vulnerabilities in the current source of a whole repository or selected paths. This is the default single-pass audit. Use the diff skill for PR, commit, branch, or working-tree changes and the deep skill for an explicitly requested deep scan.
Security audit of Odoo addon code: access control (ir.access, field groups, sudo), injection (SQL, domain, eval, XSS via Markup/markup()), untrusted public methods/RPC, controller auth/CSRF, file access, deserialization, returning complex objects, getattr/setattr, timing attacks. Use when auditing an addon, or judging whether a specific construct (a sudo, raw SQL, a route, ...) is safe.

Comprehensive security scanning and vulnerability detection. Includes input validation, path traversal prevention, CVE detection, and secure coding pattern enforcement. Use when: authentication implementation, authorization logic, payment processing, user data handling, API endpoint creation, file upload handling, database queries, external API integration. Skip when: read-only operations on public data, internal development tooling, static documentation, styling changes.
Use for authorized email security review including phishing analysis, header authentication (SPF/DKIM/DMARC), BEC patterns, and mailbox token abuse research.

Threat-model-driven security audit of a change. Build a threat model from the diff, PR, commits, and product purpose, then assess the implementation against each threat. Use when the user asks to "audit", "security-audit", "threat model", "assess for vulns", "find vulnerabilities", "security issues in this PR", or "check for IDOR/SSRF/XSS/injection" on 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 severity- and confidence-ranked findings with data flow, exploit request, and fix — no theoretical or defense-in-depth nits. Handles the GitHub review follow-up for a PR target and a reproducer test plus fix for a local branch.
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.
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.
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.
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.

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.
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.
Triage a reported security finding into a disposition: a private CVE (coordinated disclosure + advisory), a public hardening PR (fix in the open, no CVE), or not-a-security-issue (reply to reporter). 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".

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.
