Anthropic restricts Claude Code from cloning video games, blocks reverse engineering

This change aims to avoid intellectual property infringement, as confirmed by Anthropic's technical staff. While the update allows for the creation of original games or games based on user-provided assets, some users report that the Opus 5.5 model is also now blocking reverse engineering tasks, leading to community criticism. AI

IMPACT This policy change may impact AI-assisted game development and reverse engineering, potentially shifting user focus to other models or tools.

RANK_REASON The update to Claude Code is a product change and policy enforcement, not a frontier model release or significant industry event.
