Actually I am a developer and this is useful to my work so it is targeted exactly at someone like me. It would still help to have a description without going to github.
Sure, it would help, in that it would have saved you a single click.
If you had submitted the link to HN with a descriptive title, then there wouldn't have been any confusion here either. So you're complaining about the site not saying what it does (even though it says so right in the README) while at the same time submitting the link to HN with a title that doesn't say what the link is about.
As some /constructive/ feedback, do you appreciate the irony?
Just some /constructive/ feedback...
