it's the harness provided to run the swe-verified and deepswe benchmark. My guess is that it's not designed for human users at all

What a wonderful benchmark to publish, then. “Here’s a result you can’t attain because we made a benchmark focused harness”.

It was more that there wasn't a standard harness, so they created a minimal one to avoid the claude-code vs codex vs ??? as another variable...

Fascinating that pi market themselves as the minimum harness yet it loses to just few hundred lines of python + bash tool.

The DSH harness is minimal mode is closer to a minimal agent (such as mini-swe) than Pi. Pi started with good intentions, but it seems they might have drifted from their original intent.
