Anthropic 部署服务端规则拦截游戏克隆生成
Anthropic 通过不可关闭的服务端标志强制 Claude 拒绝生成特定现有游戏的克隆，但允许原创及基于用户资产的开发。该策略复用武器越狱检测栈，结合内部激活探针与概念向量距离算法，在代码重命名后仍能识别运行时行为与视觉资产的相似性以规避版权风险。

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.

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?
