Anthropic restricts Claude Code from cloning video games
Anthropic added two sentences to Claude Code's instructions so that it does not copy existing video games. Indie developers say the restriction also blocks legitimate projects, and reports say Opus 5.5 also refuses reverse engineering tasks.
Who is affected and how
- senior developer
- If you give the agent game or reverse engineering work, expect a refusal, and keep an alternative tool or a manual approach at hand.
- tech lead
- Check whether the new restriction affects your team's game, compatibility or reverse engineering tasks before you build a process on them.
- startup founder
- If your product idea relies on recreating existing games or software, a provider rule change is a business risk.
