There are two kind of icons that can be specified by a language extensions:

• extension icon
• file icons

Extension icon (implemented at 8a561d0)

This 128 png icon is defined at package.json file, on icon property.

"icon": "icons/star_128.png",

Since it is used at VSCode Marketplace, it should be available for the ones who not have the extension installed yet, i.e., don't have the icon locally. So, VSCode requeries that the icon is in the extension repository, and, of course, that the repository is specified at package.json file.

File icons (not supported by VSCode)

This icons are the ones that appear next to files (fig 1), at "Language Mode" selector (fig 2) and that can appear at file explorer (fig 3).

But, add a new icon using an extension is not currently supported by VSCode (link).

There's an open feature request here:
