Coding Mastery

This is your go-to when Claude needs to write actual code for offensive tools. It covers the full stack: Python with pwntools for exploits, C for shellcode and syscalls, Go for cross-platform implants, even assembly when you need architecture-specific tricks. The source shows real patterns like async scanners, C2 beacons with jitter, protocol parsers, and a coverage-guided fuzzer skeleton. Honestly, the breadth is the strength here. Whether you're implementing AES-GCM, building a custom network protocol, or writing position-independent shellcode, it gives Claude the context to produce working code instead of pseudocode. Maps to the weaponization phase and feeds directly into exploit development workflows.

Python (Primary — Offensive Tooling)

# Exploit development with pwntools
from pwn import *
context(arch='amd64', os='linux')

# Network programming
import socket, ssl, struct
import asyncio, aiohttp  # async operations

# Web exploitation
import requests, urllib3

C/C++ (Systems & Exploit Dev)

// Shellcode development
// Position-independent code, null-free
// Syscall-based (avoid libc dependency)

// Kernel module development
#include <linux/module.h>
#include <linux/kernel.h>
