ModularRSI improves agent harnesses using held-out tasks, paired success/failure traces, and separately evolved functional modules.

These methods can make your harness improvements more generalizable, attributable, and less benchmark-overfit.

A labeling workflow uses clustering, an LLM, a Jev classifier with an “Other” class, then a second LLM pass that can create brittle labels.

The example shows why an “Other” bucket and human checks matter when LLM-generated labels miss niche distinctions.
