you don't need your own repo, the reapack index thing is a bit complicated.
The main thing with scripts or JSFX is getting the header right, description, links to documentation, version numbers, etc.
Just look at a few that are published for the format.
I have a github page, I fork the ReaTeam JSFX folder, add my own files, then send a pull request. They fix my mistakes and put it through.
