## Summary

A new paper on arXiv introduces **Agent Harness Awareness**, a design meant to bridge the gap between an agent’s decision-making and real-time operational data. The authors argue that while tool descriptions explain *what* an action can do, they often lack context on whether it’s safe or appropriate at the moment of use. Execution systems already track this via monitors and failure logs, but the model choosing actions doesn’t access it.

The paper tests the concept with **ToolRoute**, a benchmark that isolates task semantics while varying operational information. In a 216-decision ablation across **GPT-5.6 Sol**, **Claude Sonnet 5**, and **Gemini 3.7 Flash**, verified tool-health state cut mean policy regret by **96.9%**—from **4,252 ms** to **131 ms**—and boosted single-dispatch completion from **69.4%** to **95.8%**. A separate 27-decision live test with TCP/HTTP execution and fault injection showed verified state eliminated excess regret entirely (from **8,956 ms** to **0 ms**) and improved live-action success from **5/9** to **9/9** cases.

## Key points

- Agent Harness Awareness shares verified operational state with agents before action, improving decision-making
- ToolRoute benchmark tests show 96.9% reduction in policy regret for GPT-5.6 Sol, Claude Sonnet 5, and Gemini 3.7 Flash
- Live TCP/HTTP tests confirm zero excess operational cost and 100% success rate in fault-injected scenarios

## Why it matters

This work could reduce costly agent failures by grounding decisions in real-time system health data, lowering operational risks in automated workflows.
