We added two sentences to Claude Code\u2019s prompt on Opus 5.5 to steer it away from recreating someone else\u2019s specific game because using Claude to infringe IP is against our usage policy.<\/p>\n
Original games, genre games, and games built from your own designs and assets are meant to keep working.<\/p>\n
We\u2019ll continue to iterate to ensure we\u2019re striking the right balance. In the meantime, if Claude turns down something that\u2019s yours, send it my way.<\/p>\n
\u2014 Addy Osmani (@addyosmani) October 30, 2026<\/a><\/p>\n A massive wave<\/p>\n Anthropic\u2019s new prompt comes as AI coding tools are powering a deluge of game projects based on existing work in one way or another. That includes thrown-together copies of game demos that are making some developers afraid to show their early work publicly<\/a>, as well as thousands of AI-powered decompilation and porting projects<\/a> for retro games. Thanks to AI tools, what used to be<\/a> a time-consuming process<\/a> requiring painstaking human effort<\/a> is now orders of magnitude more efficient (though some veteran coders complain that these vibe-coded ports and decomp projects fail to clear the same quality bar<\/a> as human-centered efforts<\/a>).<\/p>\n The trend has gotten so bad that decomp.dev\u2014a years-old community devoted to the \u201cbrutally difficult, time-consuming task\u201d of game decompilation\u2014announced it was shutting down<\/a> last month. Community maintainer Luke Street<\/a> wrote that quickly improving AI tools had made it clear that \u201ccommunity aspect of decompilation has been broken\u201d as newcomers \u201crac[e] to port games, especially utilizing decompilations that they did not contribute to.\u201d<\/p>\n \u201cDecomp.dev was originally designed to gamify decompilation: watching the progress go up was a fun way to stay motivated when every fraction of a percent took real human effort,\u201d Street wrote. \u201cToday, that same idea has warped decompilation into a hollow numbers game, exacerbated by folks who just want to burn tokens to make number go up or \u2018port game to PC,\u2019 all else be damned.<\/p>\n Like trying to stop the tides<\/p>\n While Anthropic\u2019s new prompt can be seen as a noble effort to push back against the flood of AI-powered, vibe-coded copying, it seems unlikely to have much impact overall. That\u2019s primarily because eager game copiers can simply shift to any of the other frontier models that haven\u2019t introduced such restrictions. And even if the AI industry as a whole began to bar this kind of use case, coders could switch to cheaper open-weight models that aren\u2019t subject to these kinds of restrictions and are not all that far behind in capabilities<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"We added two sentences to Claude Code\u2019s prompt on Opus 5.5 to steer it away from recreating someone…\n","protected":false},"author":2,"featured_media":955957,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[20],"tags":[62,276,277,49,48,61],"class_list":["post-955956","post","type-post","status-publish","format-standard","has-post-thumbnail","category-artificial-intelligence","tag-ai","tag-artificial-intelligence","tag-artificialintelligence","tag-ca","tag-canada","tag-technology"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/955956","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=955956"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/955956\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/955957"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=955956"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=955956"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=955956"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
