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.\n\nThe 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.","keyPoints":["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"],"whyItMatters":"This work could reduce costly agent failures by grounding decisions in real-time system health data, lowering operational risks in automated workflows.","category":{"slug":"agents","name":"Agents & Tools","url":"https://digestai.news/category/agents"},"entities":{"companies":[],"models":["GPT-5.6 Sol","Claude Sonnet 5","Gemini 3.7 Flash"],"people":[]},"firstPublishedAt":"2026-11-05T05:00:00Z","updatedAt":"2026-11-05T05:00:00Z","sourceCount":1,"hasPrimarySource":true,"sources":[{"outlet":"arXiv cs.AI","title":"Agent Harness Awareness: Turning Verified Telemetry into Operational Control for Tool-Using Agents","url":"https://arxiv.org/abs/2611.05391","publishedAt":"2026-11-05T05:00:00Z","type":"primary","primary":true,"lead":true}],"sourceNotes":null,"discussions":[],"thread":{"title":"The Unreliable Promise of Artificial Intelligence","url":"https://digestai.news/thread/new-study-finds-ai-struggles-to-correct-false-claims-clearly-across-languages","storyCount":5},"cite":{"text":"Digest AI, \"Researchers propose Agent Harness Awareness to improve agent decision-making with real-time telemetry\", 5 November 2026, https://digestai.news/story/researchers-propose-agent-harness-awareness-to-improve-agent-decision","publisher":"Digest AI","title":"Researchers propose Agent Harness Awareness to improve agent decision-making with real-time telemetry","datePublished":"2026-11-05T05:00:00Z","url":"https://digestai.news/story/researchers-propose-agent-harness-awareness-to-improve-agent-decision"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
