Anthropic adds new rule to Claude Code for game clones: What the AI company has to say

Anthropic has added a rule to Claude Code and Opus 5.5 that stops the AI coding tool from recreating existing video games, even renamed ones. Original and genre games should still work, engineer Addy Osmani said. Some developers, however, report refusals on their own game projects and reverse engineering tasks, while rival models and open-weight tools remain easy workarounds for anyone set on cloning games.
