RRSI Regularizes Agent Harness Self-Improvement to Prevent Overfitting
September 20, 2026
Regularized Recursive Self-Improvement (RRSI) constrains the evolution of agent harnesses—including prompts, tools, and memory—to prevent in-distribution memorization. This method maintains performance gains on out-of-distribution benchmarks during iterative harness optimization.
