Anthropic implements a new Claude Code rule to block the recreation of existing video games and protect IP rights.
Artificial intelligence firm Anthropic has updated its Claude Code tool to prevent developers from using the AI to recreate specific existing video games. The policy shift arrives amid mounting anxiety across the gaming industry regarding unauthorized game cloning.
The restriction was first spotted on October 27 by X user Chasm before the company issued an official statement. Addy Osmani, a member of the technical staff at Anthropic, later confirmed the update on social media to clarify the reasoning behind the prompt change, according to information published by dexerto.
According to the company, utilizing the Claude AI assistant to infringe upon intellectual property directly violates existing usage policies. The adjustment aims to curb unauthorized copying while maintaining standard development workflows for original titles and genre projects.
Claude Code prompt update details
Anthropic quietly introduced the modification to safeguard copyrighted material from automated duplication. Technical staff member Addy Osmani explained the exact nature of the update in a public statement shared online.
The company added two sentences to the Claude Code prompt on Opus 5.5 to steer users away from cloning specific titles. The new directive explicitly instructs the model not to build recreations of existing games, even if they receive new names.
Growing developer fears over AI cloning
The policy update addresses widespread apprehension among game developers regarding rapid asset replication. Many studios fear their upcoming projects will face imitation before official launches occur.
For instance, Alliance Arts recently cancelled the public demo for its upcoming Steam game Drunken Goddess Reflux. The studio warned that its content could be exploited to quickly imitate presentation and gameplay via AI.
Impact on Steam and intellectual property
Independent creators have increasingly pressured digital storefronts like Steam to implement stricter measures against AI clones. Platform holders face mounting questions regarding how they plan to police flooded marketplaces.
Despite the new restrictions, questions remain regarding enforcement efficacy. Claude cannot verify whether a user legally owns the intellectual property they attempt to develop, and local models lack these specific guardrails.
Future iterations and platform balance
Anthropic intends to monitor the effectiveness of the new restriction closely. The company acknowledged that balancing user freedom and intellectual property protection requires ongoing adjustments.
Addy Osmani stated that the organization will continue to iterate to ensure proper balance. Furthermore, developers who experience false positives where legitimate projects face rejection are encouraged to contact him directly.
