Summary
Brings pwntools 4.15.0 directly into Claude for binary exploitation work. You get the full toolkit: pack and unpack integers in different endianness, assemble and disassemble instructions, generate shellcode with shellcraft templates, manipulate ELF binaries, build ROP chains, and craft format string payloads. It handles process and remote socket connections, exposes cyclic pattern generation for finding offsets, and provides hexdump utilities. If you're doing CTF challenges or exploit development and want to bounce ideas off Claude while it can actually run asm(), disasm(), or generate a setreuid shellcode for you, this connects the dots. Context management and logging tools included.
Keeps your Mac awake while Claude Code, Codex or Cursor works. Lets it sleep when they are done.
