Blast Radius is a unique AI-security game that focuses on training operators to approve coding agent actions. The game presents real proposed actions such as slopsquatted installs, curl|bash commands, and skills attempting to access ~/.ssh. Players must decide to approve, sandbox, or reject the actions and provide a name for their decision. Notably, all actions must pass a deterministic correctness gate against verified ground truth before appearing on the screen, ensuring that players are not taught false lessons. Blast Radius is available as a game with a command-line interface, GitHub Action, and MCP server. It is licensed under the MIT license.
