Pentest
Static-analysis penetration test that hunts for exploitable vulnerabilities with proof-of-concept payloads and fix code. Covers SQL and NoSQL injection (string concatenation, raw queries, operator injection), XSS (reflected, stored, DOM-based, template injection, dangerouslySetInnerHTML), authentication bypass (missing auth middleware, JWT algorithm confusion, predictable tokens, OAuth state CSRF), authorization flaws (IDOR, mass assignment, horizontal/vertical privilege escalation), path traversal and file inclusion (unsanitized file paths, upload validation, LFI), command injection (exec, system, subprocess with user input), CSRF and SSRF (missing SameSite, user-supplied URLs, open redirects), hardcoded secrets (AWS keys, private keys, JWT secrets, connection strings, .env in git), and insecure deserialization (pickle, yaml.load, XXE, ObjectInputStream). Maps full attack surface with route inventory. Use for pre-release security validation, finding exploitable bugs, or generating penetration test evidence.

What this skill does
Pentest is a community-contributed Claude Code skill in the red-team sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/pentest/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The Pentest Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 174,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

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 Pentest skill?
Use Pentest when your Claude Code task falls under the Security category — specifically in the red team 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 Pentest" or describe the task and let Claude pick). Browse related skills at
/category/security/.
What is a Claude Code skill and how does the Pentest 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. Pentest is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category. Learn more at
