Anthropic 通过服务端开关限制 Claude Code 复刻现有游戏
Anthropic is cracking down on video game clones.
Anthropic 通过名为 tengu_heron_brook 的服务端开关向 Claude Code 下发规则，禁止复刻特定现有游戏，即使改名或声称原创也不行，且没有关闭选项。规则仍允许原创游戏、同类型游戏以及基于用户自有设计和素材的项目。作者认为执行层面可复用其武器越狱分类器栈，难点在于版权只保护游戏外观与感觉而非机制，检测器需区分同类型与同一款游戏。

查看原帖ANTHROPIC 正在打击电子游戏复刻行为 🚨 Claude Code 在 10 月 27 日前后收到了一条新规则，由 Anthropic 的服务器通过一个名为 "tengu_heron_brook" 的开关下发。没有任何设置可以关闭它。 完整规则如下：“要构建原创游戏、某一类型下的游戏，以及基于用户自己的设计和素材的游戏。不要构建对某一特定现有游戏的复刻，即使它被改名或被称为原创。” 这是游戏复刻、模组制作以及介于两者之间的一切的终结吗？

ANTHROPIC IS CRACKING DOWN ON VIDEO GAME REWRITES 🚨 Claude Code picked up a new rule around Oct 27, sent from Anthropic’s servers under a flag called "tengu_heron_brook". There’s no setting to turn it off. The full rule: “Do build original games, games in a genre, and games from the user’s own designs and assets. Don’t build a recreation of a specific existing game, even if it is renamed or called original.” Is this the end of game rewrites, modding and everything in between?

Anthropic is cracking down on video game clones.
Looks like the rule arrived through a server-side flag, “tengu_heron_brook”, so it reaches every session without an update and has no off switch.
The instruction still permits original games, games in a genre and projects built from a user’s own designs and assets.
Exact rule text: “Do build original games, games in a genre, and games from the user’s own designs and assets. Don’t build a recreation of a specific existing game, even if it is renamed or called original.”
To enforce the above rule it at scale, Anthropic can reuse the classifier stack it built for weapons jailbreaks: small models trained on a written rule list that read each request with its output, plus cheap probes on Claude’s internal activations that flag intent to copy a specific title.
Research tools go further, comparing code even after renaming, matching runtime behaviour and sprites, and measuring “distance” between game designs. i.e. measuring distance between them with concept vectors.
The hard part is legal: copyright protects a game’s look and feel, not its mechanics, so every detector has to separate “same genre” from “same game,” and that is where false refusals will come from.
