Anthropic restricts Claude Code from generating game clones

Anthropic has updated the system instructions for its Claude Code tool to explicitly prevent users from generating direct clones of existing video games. The change was identified following user reports revealing new constraints added to the model's backend, which mandate that the tool be used only for original works or designs owned by the user.

The updated prompt distinguishes between permissible use, such as building games within a specific genre or from personal assets, and prohibited activities, such as recreating existing intellectual property. While the tool remains functional for general programming tasks, this policy shift directly addresses the rise of AI-assisted decompilation and porting in the retro gaming sector.

The industry has seen increasing scrutiny regarding the role of AI in copyright infringement. By embedding these restrictions directly into the system prompt, Anthropic aims to distance its technology from tools that facilitate the unauthorized replication of software.

This update follows broader industry pressure to ensure generative AI tools align with intellectual property laws. Anthropic continues to allow the development of original gaming concepts while restricting features that could compromise the rights of third-party software creators.
