Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
Anthropic has updated the system prompt for Claude Code on Opus 5.5 to stop the coding tool from replicating existing games, The Verge reported on November 3. The company added two sentences to the prompt after determining that using Claude to infringe intellectual property violates its usage policy, according to Anthropic's Addy Osmani. Original games, games within the same genre, and games built from users' own designs and assets will still be supported. Osmani said Anthropic will continue tweaking the prompt to strike the right balance. The change signals growing attention to IP liability around AI coding tools, and developers will be watching how strictly the restriction is enforced and whether similar guardrails extend to other copyrighted content categories.
