For feedback, you want "Show HN" rather than "Ask HN" so it will get listed under "show" in the HN top menu. The rules for doing a "Show HN" submission are here:

I don't use WordPress, so I won't be able to help much. One thing I did notice on your site was the use of the word "opinionated" to describe your plugin. (i.e. "Pluginator is an opinionated scaffolding tool"). I know what a scaffolding tool is, but I do not know what an "opinionated scaffolding tool" is. The term "opinionated" tends to have an aggressive and negative connotation/association that you might be better off avoiding.
