Unconfirmed
The Decoder reports Anthropic is blocking Claude Code from recreating existing video games after a wave of AI-built knockoffs. Addy Osmani said Opus 5.5’s Claude Code system prompt now includes two sentences that refuse cloning even when renamed, citing usage-policy IP rules; original games and custom-asset projects remain allowed, though some users report false positives. Primary Anthropic changelog beyond the Decoder piece was not re-opened.
