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.
