Shortest code to link to CSS and JS file Is there a helper tag to output a complete stylesheet link.

I used helper tag for lack of knowledge. Helper tag is used in Statamic.

In Statamic {{ theme:css src="style" tag="true" }} outputs

&lt;link rel="stylesheet" href="/site/themes/redwood/css/style.css" /&gt;

I've seen &lt;link rel="stylesheet" type="text/css" href="{{ siteUrl }}assets/css/happylager.css"&gt; in Happy Lager's template but I'm looking for something shorter.
In Craft there's {% includeJsFile %} and {% includeCssFile %} which get injected on the getHeadHtml() and getFootHtml() functions on your templates.
