Secure
Full-stack security posture assessment with 0-100 risk scoring. Scans dependency vulnerabilities (npm audit, pip-audit, cargo audit, govulncheck), dangerous code patterns (SQL injection, eval, command injection, ReDoS, innerHTML, XSS vectors), authentication gaps (missing auth middleware, CSRF, hardcoded JWT secrets, insecure session flags), insecure crypto (MD5/SHA1 password hashing, Math.random for tokens, hardcoded encryption keys), configuration issues (exposed .env files, debug mode, permissive CORS, missing security headers CSP/HSTS, Docker root containers, default credentials), and data handling problems (PII in logs, missing input validation, file upload exploits, missing rate limiting). Produces a prioritized risk report and routes to specialized skills (pentest, owasp, gdpr, encryption, soc2). Use as a first-pass security triage before deeper audits or before shipping to production.

What does the Secure skill do?
Full-stack security posture assessment with 0-100 risk scoring. Scans dependency vulnerabilities (npm audit, pip-audit, cargo audit, govulncheck), dangerous code patterns (SQL injection, eval, command injection, ReDoS, innerHTML, XSS vectors), authentication gaps (missing auth middleware, CSRF, hardcoded JWT secrets, insecure session flags), insecure crypto (MD5/SHA1 password hashing, Math.random for tokens, hardcoded encryption keys), configuration issues (exposed .env files, debug mode, permissive CORS, missing security headers CSP/HSTS, Docker root containers, default credentials), and data handling problems (PII in logs, missing input validation, file upload exploits, missing rate limiting).

Use as a first-pass security triage before deeper audits or before shipping to production.
Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Secure skill?
Use Secure when your Claude Code task falls under the Security category — specifically in the web security area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Secure" or describe the task and let Claude pick). Browse related skills at
/category/security/.
What is a Claude Code skill and how does the Secure skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Secure is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category. Learn more at
/learn/what-is-a-claude-skill/.
