Beyond Skill Evolution: Self-Evolving Context Management Policies for Long-Horizon Agent Harnesses

ContextEvo, a framework that learns a context policy from long-horizon trajectories and reconstructs the model-visible context at key decision points, identifies context-related failures, and applies targeted policy updates, is introduced.

EvoRS: On-Policy Self-Evolution of Reward Systems for Open-Ended Reinforcement Learning

EvoRS is introduced, a self-evolving RL framework that evolves the reward system from on-policy experience, representing it as an executable Reward-DAG, and is updated from on-policy rollouts and reward traces to maintain train-time reliability.

Verify Smarter, Evolve Further: Efficient Harness Evolution through Behavior-Aware Verification

HarnessLens is introduced, a budget-aware framework for automated harness evolution that jointly explores the task space and user-configurable components, derives candidate modifications from execution trajectories, and selectively verifies each candidate on behavior-relevant tasks using an attributable-evidence gate.
