red-team-tools

red-team-tools is a skill for Claude Code, Codex from zebbern/claude-code-guide. It costs 58 tokens per session (2,016 once invoked), scanned A, original, MIT.

A security research workflow for authorized reconnaissance and vulnerability discovery, including subdomain enumeration, live-host detection, technology identification, and finding documentation.

In plain words
What is it for?
Use it to structure reconnaissance projects, discover subdomains and live hosts, identify technologies, investigate vulnerabilities, and prepare reports within a defined scope.
Why use it?
It organizes common bug-bounty and red-team tasks so researchers can cover an approved target's attack surface and record results.

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

red-team-tools 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 yesterday.

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.

Red Team Tools and Methodology

Purpose

Implement proven methodologies and tool workflows from top security researchers for effective reconnaissance, vulnerability discovery, and bug bounty hunting. Automate common tasks while maintaining thorough coverage of attack surfaces.

Inputs/Prerequisites

  • Target scope definition (domains, IP ranges, applications)
  • Linux-based attack machine (Kali, Ubuntu)
  • Bug bounty program rules and scope
  • Tool dependencies installed (Go, Python, Ruby)
  • API keys for various services (Shodan, Censys, etc.)

Outputs/Deliverables

  • Comprehensive subdomain enumeration
  • Live host discovery and technology fingerprinting
  • Identified vulnerabilities and attack vectors
  • Automated recon pipeline outputs
  • Documented findings for reporting

Core Workflow

1. Project Tracking and Acquisitions

Set up reconnaissance tracking:

# Create project structure
mkdir -p target/{recon,vulns,reports}
cd target

# Find acquisitions using Crunchbase
# Search manually for subsidiary companies

# Get ASN for targets
amass intel -org "Target Company" -src

# Alternative ASN lookup
curl -s "https://bgp.he.net/search?search=targetcompany&commit=Search"

2. Subdomain Enumeration

Comprehensive subdomain discovery:

# Create wildcards file
echo "target.com" > wildcards

# Run Amass passively
amass enum -passive -d target.com -src -o amass_passive.txt

# Run Amass actively
amass enum -active -d target.com -src -o amass_active.txt

# Use Subfinder
subfinder -d target.com -silent -o subfinder.txt

# Asset discovery
cat wildcards | assetfinder --subs-only | anew domains.txt

# Alternative subdomain tools
findomain -t target.com -o

# Generate permutations with dnsgen
cat domains.txt | dnsgen - | httprobe > permuted.txt

# Combine all sources
cat amass_*.txt subfinder.txt | sort -u > all_subs.txt

3. Live Host Discovery

Identify responding hosts:

# Check which hosts are live with httprobe
cat domains.txt | httprobe -c 80 --prefer-https | anew hosts.txt

# Use httpx for more details
cat domains.txt | httpx -title -tech-detect -status-code -o live_hosts.txt

# Alternative with massdns
massdns -r resolvers.txt -t A -o S domains.txt > resolved.txt

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.

red-team-tools is a skill published in the GitHub repository zebbern/claude-code-guide (4,600 stars, last pushed yesterday), licensed MIT. It adds 58 tokens to every session and 2,016 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
