I just hopped into the show page - of 30 items perhaps half a dozen are mildly interesting to me. There's a lot of "Something zomething agentic zzzzz..." that may well hide something good. A bunch of things that are perhaps good but not of interest to me personally (your submission would be in this category). Those half dozen that might pique my interest have all been on the front page.

I'd posit that HN is only a good place to promote things that will interest the HN crowd. Ok, not a great insight, but I don't think dropping the submission in Show HN is the problem here.
