Agent harnesses use 4 mechanisms to overcome LLM context limits

By PulseAugur Editorial · [1 sources] ·

Agents built on large language models often struggle with long tasks due to context overflow and goal loss, even with larger context windows. This article details four mechanisms used in agent harnesses to overcome these limitations: context budgeting and offloading, compaction, memory strategy, and todo-state management. These techniques, implemented by systems like LangChain Deep Agents, Claude Code, and Amazon Bedrock AgentCore, ensure that agents can maintain focus and state over extended operations by intelligently managing the information fed into the model.

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

    <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…
