pentest

pentest is a skill for Claude Code from angad-kandhari/deliberate. It costs 126 tokens per session (2,450 once invoked), scanned A, original, Apache-2.0.

A disciplined workflow for authorized penetration testing, which checks owned or approved systems for security weaknesses.

In plain words
What is it for?
It helps audit code or systems, test approved red-team, capture-the-flag, or bug-bounty targets, confirm vulnerabilities, and verify that fixes close them.
Why use it?
It keeps security testing within an agreed scope and emphasizes findings that can be reproduced and safely fixed.

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

pentest scanned grade A with 0 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 9d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Pentest

Penetration-testing skill for LLM coding agents doing authorized security assessment.

The common case: point it at your own project's codebase to find vulnerabilities, then fix each one with secure and confirm the hole is closed with verify. The same discipline scales to scoped engagements — red-team exercises, CTFs, bug-bounty targets, or a running system you have written permission to test.

Where secure keeps the code you write safe, this skill hunts for the holes that got in anyway — proves they're real, and hands each one to secure to fix. Think of them as a loop: pentest finds, secure fixes, verify confirms. Counters the failure modes of undisciplined testing — probing without authorization, thrashing without a model, "findings" that don't reproduce, and testing that damages the system it was meant to protect.


0. Authorization Is the Precondition, Not a Formality

Authorized targets only. The gate scales with the target — but it's always a gate.

  • Your own code or system: authorization is satisfied by ownership. Audit freely — this is the everyday case, and the rest of this skill is written for it.
  • Anything you don't own — a third-party service, a shared or production environment with real users' data, a client's system, a bug-bounty target: you need explicit, current, written authorization that names this target, plus the rules of engagement (in-scope hosts/accounts, allowed techniques, testing window, contact). Get it before the first probe. "Probably fine" is not authorization.
  • When in doubt about whether a target is yours to test, treat it as out of scope until you've confirmed otherwise.

Test: Do I own this target, or can I point to the authorization that covers it?


1. Map the Surface Before You Probe It

Understand the terrain first — whether that terrain is a codebase or a live host.

When auditing your own code (the common case), the source is the recon:
