When request uncertainty crosses a threshold, the agent asks for clarification rather than plowing ahead. To test it, the team created two new benchmarks — WebShop-Clarification and ALFWorld-Clarification — where half the tasks are deliberately underspecified. Across five large language models, the method improved clarification F1 on ALFWorld-Clarification by 73% over one baseline and 36% over another.\n\nMost deployed agents fail silently on vague tasks, completing the wrong thing with full confidence. A system that knows what it does not know — and says so — is considerably more useful in practice, especially in consumer or enterprise settings where users routinely give underspecified commands. The fact that the method uses only prompt engineering matters: it works with black-box APIs, requires no labeled training data, and adds no meaningful latency.\n\nThe gains held across all five model backbones tested, which suggests this is not a trick tuned to one architecture — though the benchmarks are new and self-authored, so independent replication would be a reassuring next step.","[\"ai\",\"llm-agents\",\"uncertainty\",\"benchmarks\"]","2026-06-19T04:00:00.000Z","2026-06-19T09:24:35.353Z","2026-06-19T14:21:36.340Z","published",null,[],"ai",[24,26,27,28],"llm-agents","uncertainty","benchmarks",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2606.19559",0,{"sections":35},[36,39,43,48,53,58,63,67,71,76,81,86,91,96],{"name":37,"slug":24,"count":38,"latest_published_at":18},"AI",490,{"name":40,"slug":41,"count":42,"latest_published_at":18},"Security","security",132,{"name":44,"slug":45,"count":46,"latest_published_at":47},"Policy","policy",88,"2026-06-16T09:26:09.000Z",{"name":49,"slug":50,"count":51,"latest_published_at":52},"Consumer Tech","consumer-tech",78,"2026-06-16T17:58:24.000Z",{"name":54,"slug":55,"count":56,"latest_published_at":57},"Hardware","hardware",62,"2026-06-18T15:24:16.000Z",{"name":59,"slug":60,"count":61,"latest_published_at":62},"Deals","deals",58,"2026-06-19T14:43:50.000Z",{"name":64,"slug":65,"count":61,"latest_published_at":66},"Software","software","2026-06-16T20:00:00.000Z",{"name":68,"slug":69,"count":70,"latest_published_at":18},"Dev Tools","dev-tools",50,{"name":72,"slug":73,"count":74,"latest_published_at":75},"Science","science",38,"2026-06-18T04:00:00.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Gaming","gaming",31,"2026-06-16T15:25:13.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"General","general",26,"2026-06-13T18:35:15.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"Startups","startups",23,"2026-06-16T15:00:00.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Reviews","reviews",19,"2026-06-14T08:00:00.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
