Claude Code 2.1.317 updates the rule: naming a game should yield an original game in that genre, and a request for a copy gets an offer to build something similar. This follows the earlier vendor-confirmed rule covered in the Nov. 1-2 editions.","sledRelevance":"Limited direct SLED relevance; relevant to university game-design and computing programs and to any institution relying on Claude Code. The broader point is that Anthropic changes model behavior through prompt and version updates within days, including over-blocking corrections, so institutions should version-pin and retest.
