Beyond Binary Verifiable Rewards: Behavioral Self-Rewarding for SWE Agents

Reinforcement learning with verifiable rewards (RLVR) provides reliable supervision for software engineering agents through executable tests, but binary rewards fail to distinguish trajectories with substantially different debugging quality. We investigate whether the current policy can judge its own trajectories and u...

Critic Experience Bank: Self-Evolving Step-Level Confidence Estimation for LLM Agents

This work introduces the \method (\methodshort), a self-evolving critic framework in which an LLM critic accumulates evidence from its own past judgments and their observed consequences, reducing ECE by up to $54\% relative to the strongest training-free baseline.
