The file jekyll-theme-yat.gemspec is copied to the output folder. I noticed this on my project that's based on YAT theme. I also just tried it with a fresh clone of jekyll-theme-yat into a new directory. When served, you can view http://localhost:4000/jekyll-theme-yat.gemspec in the browser.
From an infosec perspective, it's not a big deal, but the file doesn't belong there.
