Could you build this?

Partial AI evaluation and benchmark harnesses have straightforward CLI or API wrappers, but managing distributed test suites, reproducibility, and robust agentic evaluation environments introduces non-trivial system engineering.

What it would actually take: Building an evaluation harness like HarnessPAI involves a Python/Go framework managing isolated runtime environments (Docker/Firecracker microVMs) to execute agent code safely. Hard parts include sandbox security, deterministic mock environments for external tools, and token/concurrency management across large-scale model runs. It requires backend systems engineering and distributed testing infrastructure expertise.
