OWASP Top 10 testing, injection vulnerability detection, API security

appsec-foundrySkill

security-score

appsec-foundry/appsec-advisor/skills/security-score/SKILL.md

Deterministic quick Security Score (0-100) for a repository, computed from the scanner layer alone — no agents, no LLM, no threat model, nothing written into the target repository. Reports the score together with how many rules applied, the finding tally, and the weakest control domains. Use for a fast indication or a per-commit trend; it is not a risk rating and does not replace /appsec-advisor:appsec-analyzer.

Hassaan146Skill

senior-security

Hassaan146/claude-skills/senior-security/SKILL.md

Use when the user asks for STRIDE threat modeling, DREAD risk scoring, data-flow-diagram threat analysis, or a quick secret scan — or when a security request needs routing to the right specialist skill (pen-testing, incident response, cloud posture, red team, AI security, threat hunting, secure code review). This skill owns threat modeling; everything else routes to a sibling.

JeffallanSkill

security-reviewer

Jeffallan/claude-skills/skills/security-reviewer/SKILL.md

Identifies security vulnerabilities, generates structured audit reports with severity ratings, and provides actionable remediation guidance. Use when conducting security audits, reviewing code for vulnerabilities, or analyzing infrastructure security. Invoke for SAST scans, penetration testing, DevSecOps practices, cloud security reviews, dependency audits, secrets scanning, or compliance checks. Produces vulnerability reports, prioritized recommendations, and compliance checklists.

leonvanzylReads credentialsSkill

security-scanner

leonvanzyl/agentic-coding-starter-kit/.agents/skills/security-scanner/SKILL.md

Performs comprehensive OWASP Top 10:2025 security vulnerability analysis on any codebase. Use this skill whenever the user asks to: review code for security, perform a security audit, scan for vulnerabilities, find security issues, improve application security, check for OWASP compliance, do a penetration test review, assess security posture, look for security flaws, scan for security risks, harden an application, or check code for exploits. Also trigger when the user mentions OWASP, CVEs, CWEs, security hardening, vulnerability assessment, or asks for a security report — even if they don't explicitly say "security scan." This skill works on any codebase in any language (JavaScript, TypeScript, Python, Java, Go, Ruby, C#, PHP, etc.).

derHakenReads credentialsSkill

security-review

derHaken/SuperAntigravity/skills/security-review/SKILL.md

Use when reviewing code for vulnerabilities, implementing authentication or authorization, handling user input, storing sensitive data, or before any feature that touches security boundaries goes to production

karlo-ksReads credentialsSkill

security-audit

karlo-ks/Infradeck/.claude/skills/security-audit/SKILL.md

Thorough security review (security audit) of the whole codebase or part of it, reporting every vulnerability found with severity, location, attack scenario and fix. Use when the user asks for a security review, security audit, vulnerability hunt, pentest-style code review, "check the security" / "provjeri sigurnost", "security review" / "sigurnosni pregled", "are there any vulnerabilities" / "ima li propusta", or wants a component (backend, collector, docker proxy, nginx, compose, CI, frontend, assistant) reviewed for security. For a quick check of only the pending diff, the built-in security-review skill is enough.

Review Intelligent Terminal pull requests for C++/WinRT, COM, WTA, ACP, session MCP, hooks, terminal mutation, path, diagnostic, packaging, and GitHub Actions security regressions. Use for evidence-based immutable-diff review and structured HIGH/medium/low findings.

Model Context ProtocolReads credentialsSkill

security-advisory

modelcontextprotocol/inspector/.claude/skills/security-advisory/SKILL.md

Take a privately reported vulnerability through this repo's security advisory flow — board it, verify who owns the code path, accept or reject, fix it in the private fork, ship to every affected release line, publish, then turn the card into public tracking. Use when a vulnerability is reported privately; when deciding whether an advisory is ours to fix; when looking up or creating its private fork; when answering a reporter; or when a GHSA-titled board card needs handling.

SentrySkill

getsentry/warden/packages/warden/src/builtin-skills/security-review/SKILL.md

Finds exploitable application security vulnerabilities in code changes. Use for Warden security scans, appsec review, OWASP-style checks, authentication or authorization bugs, injection, XSS, SSRF, path traversal, secrets, unsafe crypto, webhook verification, open redirects, or sensitive data exposure.
