## What it does

The skill provides systematic methodologies for identifying and documenting security flaws before code ships. It includes a Python framework skeleton using a Finding dataclass to track target information, severity, CVSS scores, evidence, and concrete remediation steps.

Included reference guides focus on Burp Suite automation and security scripts such as SQL injection testing. Scope boundaries must stay firm. Running tests against production without written authorization violates the operational rules, which explicitly ban destructive payloads and sensitive data exfiltration.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill penetration-testing -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/penetration-testing/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/penetration-testing/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill penetration-testing -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/penetration-testing/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill penetration-testing -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/penetration-testing/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aj-geddes/useful-ai-prompts penetration-testing
```

2. **Manually: put the files in place**
- File: `.github/skills/penetration-testing/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill penetration-testing -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aj-geddes/useful-ai-prompts --path skills/penetration-testing
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/penetration-testing/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill penetration-testing -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/aj-geddes/useful-ai-prompts/tree/HEAD/skills/penetration-testing/SKILL.md

## When to use it
- Validate application security posture before shipping to production
- Meet compliance assessment requirements for PCI-DSS and ISO 27001
- Document security findings with CVSS scores and remediation steps
- Automate vulnerability checks using Python and Burp Suite scripts

## Example prompts
- Create an ethical penetration testing plan for our pre-production API.
- Set up a Python dataclass structure to log vulnerability findings with CVSS scores.
- Generate a remediation guide for SQL injection vulnerabilities discovered during testing.

## Overview

Systematic security testing to identify, exploit, and document vulnerabilities in applications, networks, and infrastructure through simulated attacks.

## When to Use

- Pre-production security validation
- Annual security assessments
- Compliance requirements (PCI-DSS, ISO 27001)
- Post-incident security review
- Third-party security audits
- Red team exercises

## Quick Start

Minimal working example:

```python
# pentest_framework.py
import requests
import socket
import subprocess
import json
from typing import List, Dict
from dataclasses import dataclass, asdict
from datetime import datetime

@dataclass
class Finding:
    severity: str
    category: str
    target: str
    vulnerability: str
    evidence: str
    remediation: str
    cvss_score: float

class PenetrationTester:
    def __init__(self, target: str):
        self.target = target
        self.findings: List[Finding] = []

    def test_sql_injection(self, url: str) -> None:
// ... (see reference guides for full implementation)
```

## Reference Guides

| [Burp Suite Automation Script](references/burp-suite-automation-script.md) | Burp Suite Automation Script |

## Best Practices

### ✅ DO

- Get written authorization
- Define clear scope
- Use controlled environments
- Document all findings
- Follow responsible disclosure
- Provide remediation guidance
- Verify fixes after patching
- Maintain chain of custody

### ❌ DON'T

- Test production without approval
- Cause service disruption
- Exfiltrate sensitive data
- Share findings publicly
- Exceed authorized scope
- Use destructive payloads
