Anthropic Adds 2 Sentences to Claude Code to Stop AI Video Game Clones

Anthropic has added two sentences to Claude Code's system prompt to prevent the AI coding tool from cloning video games, a move that has drawn criticism from developers who say the filter also blocks legitimate work on their own projects. The change, first reported by BeInCrypto, highlights growing tension between AI companies' efforts to curb copyright infringement and developers' reliance on coding assistants for original work. While Anthropic did not disclose specific enforcement metrics, the restriction applies to Claude Code, the company's terminal-based coding agent used widely across software development workflows. Developers report false positives that stall projects unrelated to game cloning, raising concerns about over-broad content filtering in developer tools. The episode underscores rising legal and reputational stakes for AI providers as copyright disputes intensify across the industry. Watch for whether Anthropic refines the filter, faces developer backlash affecting Claude Code adoption, or draws further scrutiny as copyright litigation involving AI-generated code continues to evolve.
