Agentic Harness Engineering Enables Agents to Self‑Evolve and Outperform Codex in 10 Rounds

The Agentic Harness Engineering (AHE) framework lets coding agents automatically read massive execution traces, identify failure patterns, and iteratively modify harness components—prompt, tools, middleware, and memory—achieving a pass@1 increase from 69.7% to 77.0% and surpassing human‑tuned Codex‑CLI after ten automated evolution rounds.
