Anthropic restricts Opus 5.5 in Claude Code from replicating existing games
Anthropic has restricted the Opus 5.5 model in its AI coding tool Claude Code from helping users replicate specific existing games. Developer @chasmmmmmmmmmmm said that around October 27, Claude Code added a rule that cannot be disabled: users may create original games, games of a certain genre, and games based on their own designs and assets, but may not replicate a specific existing game, even if renamed or claimed to be original. Anthropic technical staff member Addy Osmani responded that two lines of guidance have been added to the Claude Code prompt, and emphasized that using Claude to infringe intellectual property violates the platform's usage policy; currently, this restriction explicitly targets only Claude Code in the Opus 5.5 model.
