Anthropic updated the Claude Opus 5.5 model and Claude Code with new rules aimed at preventing the AI from helping clone or recreate existing games, even if renamed or presented as original.
The change comes amid indie developer complaints about AI-generated copies on Steam and concerns over reverse-engineering facilitated by AI tools. According to reports and a confirmation from an Anthropic staff member, a rule was added to the prompt: "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."
Collateral impact
While the goal is to curb intellectual property violations, users and developers report that the filter is blocking legitimate tasks such as debugging their own projects, replicating mechanics in original games, generic reverse-engineering, and even basic troubleshooting. GitHub issues on Claude Code and discussions on Reddit and X show developers with proven track records encountering refusals mid-work.
Anthropic confirmed the intent to "steer it away" from infringing IP but indicated it will continue iterating to balance the measure. Affected users are advised to report cases of undue blocking.
Broader context
This occurs as Steam faces problems with "AI slop" and Valve works on solutions. Anthropic had already implemented cybersecurity safeguards that route certain tasks to previous models. The situation highlights the challenge of filtering malicious uses without harming legitimate creators who use AI as a productivity tool.
