Instead of stuffing every prior tool result into each new prompt or arbitrarily trimming old ones, it builds a persistent graph tracking which earlier results actually get reused later, via a technique called Tool-Flow Analysis. A renderer then combines that reuse signal with recency and relevance to pick what fits in a fixed history budget, holding the rest in reserve. Tested on AppWorld and an 8-objective QA benchmark across three models, it matched or beat full-history performance using a 6K-token budget, cutting inference cost 10.2% to 32.2%.\n\nThis matters because context is the actual bottleneck in agent economics right now, not model capability. Every extra token an agent carries forward costs money and latency, and most current context-trimming approaches guess at relevance without checking whether information gets used downstream. Tracking actual reuse instead of just recency or semantic similarity is a more grounded signal, and a 10-32% cost cut at equal or better task performance is a real number for anyone running agents at scale, not a marketing one.\n\nIt is also a tell about where the field's attention is shifting. A year ago the race was about context window size; this paper is a reminder that a bigger window doesn't solve the problem if the agent still can't tell what in it matters.","[\"ai agents\",\"llm\",\"context management\",\"arxiv\"]","2026-09-30T04:00:00.000Z","2026-09-30T09:19:34.193Z","2026-09-30T09:19:39.980Z","published",null,[],"ai",[26,27,28,29],"ai agents","llm","context management","arxiv",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.37743",0,{"sections":36},[37,40,44,48,53,58,63,68,73,78,83,88,93,98],{"name":38,"slug":24,"count":39,"latest_published_at":18},"AI",5028,{"name":41,"slug":42,"count":43,"latest_published_at":18},"Security","security",780,{"name":45,"slug":46,"count":47,"latest_published_at":18},"Policy","policy",417,{"name":49,"slug":50,"count":51,"latest_published_at":52},"Deals","deals",284,"2026-09-29T21:00:00.000Z",{"name":54,"slug":55,"count":56,"latest_published_at":57},"Hardware","hardware",194,"2026-09-29T13:16:04.000Z",{"name":59,"slug":60,"count":61,"latest_published_at":62},"Science","science",154,"2026-09-28T13:19:18.000Z",{"name":64,"slug":65,"count":66,"latest_published_at":67},"Consumer Tech","consumer-tech",142,"2026-09-29T18:38:03.000Z",{"name":69,"slug":70,"count":71,"latest_published_at":72},"Software","software",91,"2026-09-25T20:55:00.000Z",{"name":74,"slug":75,"count":76,"latest_published_at":77},"Dev Tools","dev-tools",89,"2026-09-29T17:15:00.000Z",{"name":79,"slug":80,"count":81,"latest_published_at":82},"Startups","startups",83,"2026-09-29T21:51:36.000Z",{"name":84,"slug":85,"count":86,"latest_published_at":87},"General","general",49,"2026-09-28T16:44:57.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"Gaming","gaming",48,"2026-09-25T18:35:21.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",31,"2026-09-28T14:31:34.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
