Claude Pentest Skills

Structured Web Application Penetration Testing with Claude Code

OWASP-based methodology, curated payload references, strict validation gates, and report generation — all orchestrated through slash commands.

  6 slash commands  ·  3 agent personas  ·  18 vuln classes
  6-gate validation  ·  OWASP WSTG mapped  ·  PDF report gen

The Problem

Pentesting with AI is powerful, but without structure it's chaotic:

• Claude sends payloads to out-of-scope targets
• Findings are false positives that waste report-writing time
• No consistent methodology — different approach every session
• Payload knowledge scattered across bookmarks and notes
• Reports are written from scratch every engagement

The Solution

Claude Pentest Skills is a structured skill pack for Claude Code. It enforces scope, follows OWASP methodology, validates findings through a 6-gate quality process, and generates professional reports — all through simple slash commands.

Quick Start

Step 1 — Clone

git clone https://github.com/frendysanusi/claude-pentest-skills.git
cd claude-pentest-skills

Step 2 — (Optional) Set up tools

# Burp Suite MCP
cp .mcp.json.example .mcp.json
# Edit with your local paths

# PDF report generation
python3 -m venv .venv
.venv/bin/pip install markdown weasyprint

Step 3 — Hunt

claude                          # Start Claude Code in the project dir

/scope target.com               # Define authorization (REQUIRED first step)
/recon target.com               # Map attack surface
/hunt injection                 # Test for SQLi, NoSQLi, CMDi, SSTI, XXE
/validate                       # 6-gate quality check
/report --full                  # Generate pentest report

Each command loads the right agent persona, methodology skill, and payload references. State is tracked per engagement in engagements/<target>/.

Commands

Hunt Targets

/hunt injection        # SQLi, NoSQLi, CMDi, SSTI, XXE
/hunt auth-access      # IDOR, JWT, OAuth, privilege escalation
/hunt server-side      # SSRF, path traversal, file upload, deserialization
/hunt client-side      # XSS, CSRF, open redirect
/hunt session          # Session fixation, token weakness, cookie security
/hunt business-logic   # Race conditions, workflow bypass, logic flaws
/hunt config           # Headers, CORS, TLS, info disclosure
/hunt ai-llm           # Prompt injection, LLM tool abuse, system prompt leakage

# Or target specific sub-classes:
/hunt sqli             /hunt xss              /hunt ssrf
/hunt idor             /hunt jwt              /hunt prompt-injection

Agent Personas

3 specialized personas, each activated by the relevant command:

When no command is active, Claude behaves as a general security consultant.

Validation Gate

Every finding must pass all 6 gates to reach the report. One failure = REJECTED or NEEDS-WORK.

Finding ──> Gate 1: Reproducible PoC?
            Gate 2: HTTP evidence captured?
            Gate 3: Impact verified (not theoretical)?
            Gate 4: Target in scope?
            Gate 5: Real vulnerability (not informational)?
            Gate 6: Client can reproduce it?
                         │
              ┌──────────┼──────────┐
              │          │          │
          VALIDATED   REJECTED  NEEDS-WORK
          (→ report)  (killed)  (fix & retry)

This process eliminates false positives, ensures evidence quality, and produces findings that clients can verify independently.

Tool Integration

SQLMap and Commix are used only after manual detection confirms the vulnerability. Never as first-pass scanners.

Local Payloads

The public payloads/ directory contains methodology and payload references. For curated payload lists with full exploit code, add them to local-payloads/ (gitignored):

mkdir local-payloads
# Add your curated .md files with full payloads here
# The hunt skills will reference both payloads/ and local-payloads/

Safety Rules

These are enforced in CLAUDE.md. Non-negotiable.
