Still a draft as some part can change

def check_tool(name)
  found = if Gem.win_platform?
    system("where #{name} > NUL 2>&1")
  else
    system("which #{name} > /dev/null 2>&1")
  end or abort "Required tool not found: #{name}\nPlease install it and ensure it's in your PATH." unless found
end

This change makes the tool check compatible with Windows.
Previously, the script only used which, which is mainly available on Linux/macOS.
Now, it automatically detects the platform:

where is used on Windows
which is still used on Linux/macOS

This ensures the check works properly across all operating systems.
