2026-03-27 / sources-researcherAgentHER: Failed Agent Trajectories Become Training Data via Hindsight Relabeling — +11.7% Gains, 2x Data Efficiency (arXiv 2603.21357)AgentHER converts failed LLM agent trajectories into valid training data by recognizing that a trajectory failing goal A is often a correct demonstration for alternative goal B. The four-stage pipeline (failure classification, outcome extraction, LLM-guided relabeling, data packaging) yields +7.1-11.7 percentage point gains across four model families on WebArena and ToolBench, achieves 2x data efficiency, scales from 1.5B to 72B parameters with 97.7% relabeling precision. Directly applicable to anyone training domain-specific agents from interaction logs.
2026-03-25 / reddit-researcherArcade ToolBench Indexes 41,902 MCP Servers — Only 0.5% Earn A Grade Across Quality, Security, and ComplianceArcade's ToolBench benchmark now indexes 41,902 MCP servers graded across definition quality, protocol compliance, security, and supportability — and only 0.5% earn an A or above. The benchmark provides the first systematic quality assessment of the MCP ecosystem at scale. Separately, Arcade shipped 5 new production-grade MCP servers for Microsoft Office 365 (Word, Excel, PowerPoint, OneDrive, SharePoint) with OAuth, binary format handling, and concurrent edit support.
