If you're stuck on Windows and miss grep, awk, or sed, this gets you a BusyBox binary that runs those Unix tools natively. It's not WSL, just a single executable you download from frippery.org with builds for 32-bit, 64-bit, and ARM processors. You prefix commands with busybox.exe, like busybox.exe grep or busybox.exe ls. The skill walks you through detecting your system architecture and grabbing the right build. Honestly, it's a lighter alternative when spinning up WSL feels like overkill for a quick text processing task or when you need Unix tools in an environment where WSL isn't available.
