The point about the URL you paste is underrated. If the link goes to a signup wall, the title barely matters because the first comments will be about not being able to try it. On naming the tool you integrate with, I'd name it when it's the reason someone would click, like "for Postgres" or "for Figma files," and leave it out when it's just part of your stack. The first comment is where I'd put the honest version of how it works and what it doesn't do yet, since that's usually what HN readers ask about first.
