Skill: Setup

Sets up a Mac or Windows PC for ButterCut. On a Mac, two installation paths are available based on user preference.

Step 0: Which platform is this?

uname -s

• Darwin → macOS. Continue with Step 1 below.
• MINGW… / MSYS… / CYGWIN… → Windows (Git Bash). Read and follow skills/setup/windows-setup.md — it has its own check-current-state flow — then come back for Step 5 (the error-reporting question).
• uname not found at all → almost certainly PowerShell on Windows without Git for Windows; that's the first thing windows-setup.md installs.

Step 1: Check Current State

(macOS path — Windows machines went through windows-setup.md in Step 0.) Run each check below. Each command exits 0 when the dependency is present. Note which ones fail — that's what setup needs to install.
