What's "at-username" called? at-handle?

Question

I'm establishing standards for my code projects.

Among those, is that I want contributors attribute their notes to their GitHub username, in forms similar to: "@username".

I'll need to document this, but I'm not sure what it's called, maybe "at-handle" or something?

Answer 1

The GitHub documentation calls it "@username format" (since your unique textual identifier on the site is a "username"):

The pattern is followed by one or more GitHub usernames or team names using the standard @username or @org/team-name format.

When used to create a notification for another user, it's called an "@mention" but it doesn't sound like that applies to your situation.

Note of course that other sites may have their own terms for this type of thing.
