WordPress SEO by Yoast is the ultimate SEO plugin, and it can do pretty much everything. And we usually get people asking how to change the description tag for our themes which use a front-page.php template.
It's really easy to do it. Just navigate to SEO > Titles & Metas > Homepage, and there you can manage title and meta description template. And if you also want to add meta tags, then you will have to enable it first from the SEO > Titles & Metas > Other tab.
