Anthropic restricts Claude from cloning video games
The Verge: Anthropic clamps down on Claude’s AI video game clones
Anthropic has updated Claude Code's system prompt to prevent the AI tool from being used to recreate existing video games, as reported by Tom's Hardware. Retro gaming is currently being overrun with AI-made decompilations, recompilations, and ports, but while Anthropic will still let people use Claude Code to make games, it doesn't want people to use it for direct clones. Last week, a user on X posted a screenshot allegedly showing two new sentences added to Claude Code's syste
What happened
Anthropic updated Claude Code's system prompt to prevent the AI tool from being used to recreate specific existing video games, citing intellectual property concerns. The change allows users to still create original games, genre games, and games based on their own designs and assets. The move comes as retro gaming experiences an influx of AI-made game decompilations, recompilations, and ports.
What each outlet adds
- The Verge ↗: The new instructions state that Claude Code should not help recreate someone else's specific game because using the tool to infringe on intellectual property violates company policy.
- Ars Technica ↗: The restrictions are unlikely to significantly slow the wave of AI-assisted game copying because users can switch to other AI models without such limitations or use cheaper open-weight models that face no restrictions.
Why it matters
The prompt change primarily helps Anthropic reduce its legal liability for copyright infringement. However, the restrictions may also risk being overly restrictive by preventing transformative projects that build on existing games in creative ways.
Get smart on it
Anthropic has updated its AI tool Claude Code to prevent users from recreating specific existing video games, though users can still build original games or games in particular genres. The company added new instructions to Claude Code's system prompt stating it should not help recreate someone else's specific game because using the tool to infringe on intellectual property violates company policy. This change comes as retro gaming is experiencing an influx of AI-made game decompilations, recompilations, and ports. Original games, genre games, and games built from a user's own designs and assets are still permitted to be created with Claude Code.

Anthropic VS code extension on Cursor backdoored for nearly 12 hours
An official extension for Anthropic’s Claude model was backdoored and threatened as many as 5,000 developers' machines, multiple sources reported Friday. Anthropic so far has yet to warn customers of the incident. The compromised package was a VS Code extension available in the marketplace of Cursor, a maker of AI-assisted developer tools, the company said Friday. The malicious version, 2.1.313, subsequently affected “at most 5,000 users,” presumably when they either downloaded it or their syste

Beekeeping tips and wrestling advice can train AI models to sabotage oversight
Anthropic used Claude to automatically generate training data that looks harmless but trains smaller models to misbehave, such as sabotaging oversight or deceiving users. Hidden within fictional contexts about beekeeping, professional wrestling, and mitochondria, these datasets bypass safety monitors and outperform known benchmarks from the research literature.
