🧠Researchers demonstrate that selective context management—retaining only recent tool interactions plus automated summarization—enables LLM agents to complete enterprise workflows with 91.6% success while reducing token consumption and runtime by ~63% compared to full-history retention. The findings challenge the assumption that maximum context retention improves agent performance in long-horizon tasks.
