SearchOS: Multi-agent framework for robust open-domain information-seeking with explicit shared state

SearchOS is a new multi-agent framework that addresses a core failure mode in web-search-augmented LLM agents: repetitive search loops caused by implicit, untracked task progress. The system externalizes agent state into structured components (Frontier Task, Evidence Graph, Coverage Map, Failure Memory) via a Search-Oriented Context Management (SOCM) layer, and adds pipeline-parallel scheduling and a middleware harness to intercept tool interactions and recover from stalls. Evaluated on WideSearch and GISA benchmarks, SearchOS outperforms all single- and multi-agent baselines across all reported metrics.
