Anthropic steers Claude Code away from recreating specific video games (Opus 5.5)
Anthropic updated Claude Code’s system prompt on Opus 5.5 to steer the model away from recreating someone else’s specific game, saying use of Claude to infringe IP is against its usage policy. Anthropic engineer Addy Osmani said two sentences were added to the prompt to discourage direct recreations, while original games and games built from users’ own designs or assets should still work; the company did not confirm the exact wording reported by Tom's Hardware.
