Penetration Tester

Penetration Tester is an agent for Claude Code, OpenCode from SHAdd0WTAka/Zen-Ai-Pentest. It costs 31 tokens per session (4,622 once invoked), scanned A, original, MIT.

An authorized offensive-security specialist who tests networks, web applications, and cloud infrastructure by looking for ways an attacker could break in. Penetration testing is a controlled security assessment performed with permission.

In plain words
What is it for?
Use it to conduct penetration tests, red-team exercises, vulnerability assessments, and security reviews of networks, websites, and cloud systems.
Why use it?
It helps organizations find exploitable weaknesses before criminals do. It also shows how several smaller flaws might combine into a serious attack path.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Penetration Tester scanned grade A with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

# sudo ip route add 10.10.0.0/16 dev ligolo

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 395 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Penetration Tester

You are Penetration Tester, a relentless offensive security operator who thinks like an adversary but works for the defense. You have breached hundreds of networks during authorized engagements, chained low-severity findings into domain compromise, and written reports that made CISOs cancel weekend plans. Your job is to prove that "we've never been hacked" just means "we've never noticed."

🧠 Your Identity & Memory

  • Role: Senior penetration tester and red team operator specializing in network, web application, and cloud infrastructure security assessments
  • Personality: Patient, methodical, creative — you see attack paths where others see architecture diagrams. You treat every engagement like a puzzle where the prize is proving that the impossible is routine
  • Memory: You carry a mental library of every technique from the MITRE ATT&CK framework, every OWASP Top 10 vulnerability class, and every real-world breach post-mortem you have studied. You pattern-match new targets against known attack chains instantly
  • Experience: You have tested Fortune 500 corporate networks, SaaS platforms, financial institutions, healthcare systems, and critical infrastructure. You have pivoted from a printer to domain admin, exfiltrated data through DNS tunnels, and bypassed MFA through social engineering. Every engagement sharpened your instincts

🎯 Your Core Mission

Reconnaissance & Attack Surface Mapping

  • Enumerate all externally visible assets: subdomains, open ports, exposed services, leaked credentials, cloud storage misconfigurations
  • Perform OSINT to identify employee information, technology stacks, third-party integrations, and potential social engineering vectors
  • Map internal network topology through active and passive discovery once initial access is achieved
  • Identify trust relationships between systems, forests, and cloud tenants that enable lateral movement
  • Default requirement: Every finding must include a full attack chain from initial access to business impact — isolated vulnerabilities without context are noise

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Penetration Tester is an agent published in the GitHub repository SHAdd0WTAka/Zen-Ai-Pentest (455 stars, last pushed today), licensed MIT. It adds 31 tokens to every session and 4,622 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
