pentest-checklist

pentest-checklist is a skill for Claude Code, Codex from zebbern/claude-code-guide. It costs 57 tokens per session (2,241 once invoked), scanned A, original, MIT.

A structured guide for planning, running, and following up on penetration tests, which are authorized attempts to find security weaknesses in software or networks.

In plain words
What is it for?
Use it to set test scope, prepare the environment, collect monitoring data, document vulnerabilities, and plan and verify fixes.
Why use it?
It helps teams define objectives, targets, permissions, timelines, and expected results before testing begins.

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-checklist scanned grade A with 1 finding 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 4d 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 systemctl restart rsyslog

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

Pentest Checklist

Purpose

Provide a comprehensive checklist for planning, executing, and following up on penetration tests. Ensure thorough preparation, proper scoping, and effective remediation of discovered vulnerabilities.

Inputs/Prerequisites

  • Clear business objectives for testing
  • Target environment information
  • Budget and timeline constraints
  • Stakeholder contacts and authorization
  • Legal agreements and scope documents

Outputs/Deliverables

  • Defined pentest scope and objectives
  • Prepared testing environment
  • Security monitoring data
  • Vulnerability findings report
  • Remediation plan and verification

Core Workflow

Phase 1: Scope Definition

Define Objectives
  • Clarify testing purpose - Determine goals (find vulnerabilities, compliance, customer assurance)
  • Validate pentest necessity - Ensure penetration test is the right solution
  • Align outcomes with objectives - Define success criteria

Reference Questions:

  • Why are you doing this pentest?
  • What specific outcomes do you expect?
  • What will you do with the findings?
Know Your Test Types
Type Purpose Scope
External Pentest Assess external attack surface Public-facing systems
Internal Pentest Assess insider threat risk Internal network
Web Application Find application vulnerabilities Specific applications
Social Engineering Test human security Employees, processes
Red Team Full adversary simulation Entire organization
Enumerate Likely Threats
  • Identify high-risk areas - Where could damage occur?
  • Assess data sensitivity - What data could be compromised?
  • Review legacy systems - Old systems often have vulnerabilities
  • Map critical assets - Prioritize testing targets
Define Scope
  • List in-scope systems - IPs, domains, applications
  • Define out-of-scope items - Systems to avoid
  • Set testing boundaries - What techniques are allowed?
  • Document exclusions - Third-party systems, production data

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.

pentest-checklist is a skill published in the GitHub repository zebbern/claude-code-guide (4,599 stars, last pushed today), licensed MIT. It adds 57 tokens to every session and 2,241 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
