New framework automates agent harness optimization
A developer has built a framework designed to automate the optimization of AI agent harnesses—the control scaffolding that manages planning, tool calls, work verification, and error recovery around large language models. The framework's optimization capabilities were demonstrated on Terminal-Bench, a highly demanding benchmark for terminal-based agentic tasks.
Automated harness optimization represents a significant shift from manual prompt engineering to algorithmic tuning of agentic systems. By systematically adjusting execution scaffolding rather than modifying underlying model weights, developers can yield massive performance gains on complex benchmarks.
- –Automated optimization shifts focus from manual prompt tweaks to algorithmic optimization of agent execution flows.
- –Harnesses are critical bottleneck areas where minor adjustments in verification and recovery logic translate to huge score improvements.
- –Terminal-Bench provides a highly robust testbed due to its script-verified outcomes.
