GoKawiilAnthropic adds prompt restrictions to Claude Code against cloning specific games
Anthropic revised the system prompt for Claude Code on its Opus 5.5 model, inserting instructions directing the AI to avoid recreating specific existing video games. The company says the change enforces its usage policy against using Claude to infringe intellectual property, while original games, genre-style games, and projects built from a user's own designs and assets should still function normally.
GoKawiil's interpretation of the reporting above, not reported fact.
The move signals Anthropic is trying to preempt copyright and IP disputes tied to AI coding tools that can replicate recognizable commercial games, a concern that has dogged generative AI products broadly. Anthropic's acknowledgment that it will keep adjusting the balance suggests the current filters may produce false positives, blocking legitimate original work, which the company is inviting users to report.
- Claude Code's Opus 5.5 prompt now includes explicit guardrails against cloning specific existing games.
- Anthropic frames the change as enforcement of its IP infringement usage policy.
- The company says original and genre-based games should remain unaffected and is soliciting feedback on misfires.
