Adaptive Auto-Harness: Sustained Self-Improvement for Agentic System Deployment on Open-Ended Task Streams
arXiv:2606.01770v1 Announce Type: new Abstract: Auto-harness systems such as A-Evolve, GEPA, and Meta-Harness improve LLM agents by optimizing prompts, skills, tools, memories, and supporting infrastructure from execution feedback, but they are typically evaluated on fixed offline benchmarks. Real deployments instead present open-ended task streams: histories grow without a fixed endpoint, heterogeneous tasks require different harnesses, and problem distributions shift over time. These challenges make a single repeatedly and densely updated harness brittle, causing performance degradation as a
The proliferation of LLMs and agentic systems in real-world applications is increasing, making the limitations of fixed-benchmark evaluations for continuous deployment highly apparent.
Adaptive auto-harness systems promise to enable AI agents to maintain and improve performance in dynamic, open-ended environments, a critical capability for widespread autonomous system adoption.
The focus for agentic system development shifts from optimizing for static benchmarks to designing for sustained self-improvement and adaptability in real-world, evolving task streams.

AI agents become more robust and reliable in live operational settings.
This increased reliability accelerates the adoption of AI agents across various industries, replacing more complex human workflows.
As agents self-improve and adapt to novel conditions, the scope of tasks that can be fully automated expands significantly, leading to a re-evaluation of human roles and organizational structures.
