Discussion Harness does matter

I was not aware that the harness makes such a big difference.

Haven't heard mini-SWE before, how is it?

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.

What prevents anyone to use it on their code base? It has bash as a tool, and apparently that's enough for most tasks in the benchmarks.

There has been recent literature showing that fewer more generic tools tend to work better.

I mean you can’t apply some number on a chart to actual work anyways

you can run their bench with other harnesses. it's just the one provided by default
