‡ Core contribution (marked † in the source paper)
Recursive Self-Rewrite turns successful trajectories discovered under diverse harnesses into reusable capabilities under a general harness. It expands 2,001 trajectories to 11,094 and improves Qwen-3.8-27B pass@3 from 57.0% to 74.2% on Terminal-Bench 2.
