BenchGuard

Audit scientific or agent benchmarks using BenchGuard's cross-artifact verification methodology. Use when the user asks Codex to inspect benchmark tasks for instruction, ground-truth, evaluator, environment, or scoring defects; to produce BenchGuard-style JSON/Markdown audit reports; or to review a standard-format benchmark without installing the Python package.

Audit ProgramBench-style cleanroom benchmark tasks for verified fairness blockers: hidden/non-discoverable CLI flags, subcommands, env/config behavior, and active tests that require undefined, accidental, platform-specific, TTY, timing, or implementation-artifact behavior. Use when the user asks to review ProgramBench tasks, cleanroom reproducibility, from-scratch reimplementation fairness, active tests, hidden interfaces, or benchmark issues.
