Claude Code steers away from recreating existing games
Policy changeAnthropic27 Oct 2026
Anthropic added two sentences to Claude Code's system prompt for Opus 5.5: build original games, games in a genre and games from the user's own designs and assets, but not a recreation of a specific existing game, even if it is renamed or called original. The rule is served from Anthropic's side and can't be switched off. It was first reported on 27 October; Anthropic confirmed the rule, though not the date, on 30 October.
Anthropic said the change is meant to keep Claude from being used to infringe IP, that original and genre games should keep working, and that it plans to refine the rule. Developers reported that modding, debugging and similar work was caught by it too.
