Anthropic has updated its AI assistant Claude to prevent it from being used to reverse-engineer or clone existing video games.

What it means

Anthropic has updated its AI assistant Claude (specifically Claude Code and the Opus 5.5 model) to refuse requests that involve reverse-engineering or cloning existing video games. This is a policy change likely aimed at reducing copyright infringement risks and responding to pressure from game publishers, but it has drawn criticism from developers who used Claude for legitimate reverse-engineering tasks.

Accuracy & sourcesGrounded

The claim is based on multiple tech news reports (Mashable, Engadget, Tom's Hardware) that cite user reports and Anthropic's apparent policy update. No official statement from Anthropic is directly quoted, and the provenance tier is aggregated/secondary with no primary cited, so the accuracy is moderate but consistent across sources.

How new

Genuinely new: the reporting window is October 31 to November 2, 2026, and no recirculation year is given.
