How is this determining a comment is "Highly Upvoted" on HN where that is explicitly kept out of the ui/ux and new comments are a/b tested across users etc... it's not a thing you can know. I have had comments with a big number of descendents but very low upvotes so thats not a reliable indicator either. Genuinely curious.
Here is the prompt I used!
* contrarian_view: * Look for the most upvoted comment that DISAGREES with the article's premise or the majority sentiment * This is the "steelman" of the opposing view - the most compelling counter-argument * If no significant contrarian view exists, set has_contrarian to false * Focus on constructive disagreement, not flame wars
