Claude Opus 5.5 users say reverse-engineering prompts now get cut off

Users say Claude Opus 5.5, the model behind the AI game-decompilation wave, now halts reverse-engineering requests mid-answer, but Anthropic hasn’t confirmed any change. Users of Claude Opus 5.5 say Anthropic’s flagship model now cuts itself off when asked to reverse-engineer software, the same skill many credit for the recent flood of AI-assisted game decompilations and recompilations. The complaints surfaced on r/Claude on 21 October, and Kotaku reports that Anthropic hasn’t announced or released a new version of Opus 5.5. Nothing has been confirmed, so for now this is a pattern of user reports rather than a documented change. Found us on Google?
