English(EN) Context Engineering Inside the Harness: 4 Mechanisms That Beat Context Overflow and Goal Loss on Long-Horizon Tasks

Agent Harness使用4种机制克服LLM上下文限制

作者 PulseAugur 编辑部 · [1 个来源] · 2026-09-13 05:56

基于大型语言模型的Agent在长任务中常常因上下文溢出和目标丢失而挣扎，即使拥有更大的上下文窗口也难以幸免。本文详细介绍了Agent Harness中用于克服这些限制的四种机制：上下文预算和卸载、压缩、记忆策略以及待办事项状态管理。这些技术，由LangChain Deep Agents、Claude Code和Amazon Bedrock AgentCore等系统实现，通过智能管理输入模型的信息，确保Agent在长时间操作中能保持专注和状态。 AI

影响提高了LLM Agent在复杂、长周期任务中的可靠性和能力。

上下文工程在Harness内部：4种机制，在长周期任务中克服上下文溢出和目标丢失

<p>A shallow agent is an LLM calling tools in a loop, and on long tasks it fails in 2 ways: context overflow and goal loss. This article opens the harness layer that fixes both, with the actual thresholds shipped by LangChain Deep Agents, Claude Code, Manus, OpenAI Codex and Amaz…
