Read the Hacker News front page ranking and return each story with title, points, author, comment count, source domain, external URL and HN discussion permalink. Use it when the user asks what is on the HN front page, what the top or most upvoted stories are, for the links or authors of current stories, or for a later page of the ranking. One page holds 30 stories: page 2 returns ranks 31-60. Keyword and comment-count filtering are done by the caller over the returned list, not by this tool. It reads news.ycombinator.com's own /news page from an open news.ycombinator.com tab, so there is no API key, no token and no login. Job posts come back with points 0 and an empty author; text posts (Ask HN, or Show HN with no link) come back with url equal to hn_url.
