Anthropic adds two sentences to Claude Code's Opus 5.5 prompt to steer it away from recreating specific existing games; original and genre games still allowed
Around Oct 27, users noticed Claude Code receiving a new server-side rule (flag name tengu_heron_brook): build original games, games in a genre, and games from the user's own designs and assets, but do not build a recreation of a specific existing game, even if it is renamed or called original. The post that surfaced it drew about 8,700 likes and nearly 2 million views on Oct 30. The same day, Addy Osmani, who works on Claude Code at Anthropic, confirmed on X that the team added two sentences to Claude Code's prompt on Opus 5.5 because using Claude to infringe IP is against Anthropic's usage policy. He said original games, genre games, and games built from your own designs and assets should keep working, that the team will keep iterating, and that users can send him wrongly refused requests.

X discussion: Anthropic engineering manager Felix Rieseberg says he dropped coding interviews for his team, arguing "hunger beats tenure", and the post passes 1M views
Felix Rieseberg, whose X bio says he builds things at Anthropic, posted on Oct 27 that the coding interview is "dead, at least for my team at Anthropic" and that he removed it from his hiring loops this month, linking an essay titled "Hunger beats tenure" with advice for junior engineers. The post drew about 9,500 likes, over 1 million views and more than 10,000 bookmarks, sparking wide debate. This is his personal view and his teams practice, not an official Anthropic hiring policy.
