Key features	Sandboxed execution with non-privileged user isolation Process termination before grading Suspicious file detection and rejection Out-of-memory and fork-bomb prevention Hardened through one million evaluation runs Red-team tested for reward hacking vulnerabilities Scalable environment execution Robust benchmark building support	Real-time tokens per second display in status bar Request wait time tracking Cache hit rate and context size metrics Codex rate limit usage tracking Live terminal session table Works with any model the agents run Offline operation, no network requests Integration with Claude Code status line
What makes it different	Provides secure defaults and primitives specifically designed to prevent reward hacking in RL training Hardened through real-world testing at scale with over one million evaluation runs Designed for training environments where defenses must withstand continuous optimization attempts Addresses AI alignment at the highest leverage point through better environment construction Built and tested internally by frontier AI research team	Works offline with no API key required, reading only session logs on your computer Integrates into VS Code status bar, Claude Code status line, and terminal Shows actual achieved speed including wait time, not theoretical maximums
