Claude Code, Anthropic’s AI coding tool, is reportedly refusing a growing range of requests tied to video game cloning and reverse engineering. According to a Tom’s Hardware report published on 31 October, developers say Claude Code and/or the Opus 5.5 model have blocked attempts to recreate existing games, along with some reverse-engineering and troubleshooting tasks that users describe as harmless. Anthropic has not made an official statement on the matter.
What Claude Code users are reporting
The reports fall into two groups. The first involves games. Claude Code’s GitHub repository has seen an influx of issues from users complaining that the tool refused standard game work, including requests made halfway through development, attempts to replicate a game mechanic and patching a tabletop-style game. Tom’s Hardware notes that some of those reports may come from users with bad intentions, but at least one comes from a developer with a real track record.
The second group involves reverse engineering. Users on Reddit and other platforms have reported Claude refusing tasks such as analyzing a simple Windows crash dump, removing unwanted software from a Samsung TV and using the popular Reverse Engineer Anything (REA) tool at all. Some game developers also say Claude blocked anti-cheat development and security reviews of their own games, citing its safeguards.
The game rule behind the Claude Code refusals
The game-related refusals may be linked to a text rule now in force. According to X user Chasm, the rule reads: “Do build original games, games in a genre, and games from the user’s own designs and assets. Don’t build a recreation of a specific existing game, even if it is renamed or called original.”
There is no official confirmation that this is the actual rule text. Tom’s Hardware calls it plausible given the clear refusals developers have encountered over the past week.
The publication links the rule to a wider problem. Game developers have reportedly faced a flood of AI-cloned titles, and some say they have been targeted by extortion scams threatening to clone their game demos into full games before the originals are finished. The recent Steam Next Fest also drew criticism for AI-made entries copied from existing titles.
Cyber restrictions may also play a role
The reverse-engineering refusals may have a separate cause. On 6 October, Anthropic introduced its Cyber Verification Program, which limits access to its frontier models’ advanced cybersecurity capabilities to entities covered by Project Glasswing, effective immediately.
Tom’s Hardware suggests the same ruleset could be behind the cybersecurity-related refusals. However, it notes that 24 days passed between that change and the start of the recent complaints, which only began about a week ago.
The report also points to a likely motive: AI companies may be protecting themselves from lawsuits by software makers, including game studios, over tools that help reverse-engineer their products. Anthropic is not alone, either. OpenAI recently deactivated the account of a person who was trying to clean up their TV’s software, according to the report.
What it means for developers using Claude Code
For now, developers have little official guidance. Online reaction has included suggestions to switch to Chinese, open-weight or local models for reverse-engineering work. Without a statement from Anthropic, it is unclear which refusals are intended and which are side effects of broader safeguards.
From my perspective, the hardest part here is the line between cloning someone else’s game and legitimate work on your own project. Clearer public rules would help both sides.

FAQ
Is Claude Code blocking game development?
Users report that Claude Code refuses to recreate specific existing games, and some say it blocked work on their own games. Original games and genre games appear to be allowed under the reported rule.
Has Anthropic confirmed the new rules?
No. According to Tom’s Hardware, Anthropic has made no official statement, and the reported rule text has not been confirmed.
Why might Claude refuse reverse-engineering tasks?
The refusals may relate to Anthropic’s Cyber Verification Program, introduced on 6 October, or to legal caution, but the cause has not been confirmed.
