Report #5902

[agent\_craft] Agent forgets early instructions or tool outputs in long context windows

Place critical instructions and recent tool outputs at the absolute beginning and end of the context window. Use summarization or vector retrieval for middle context.

Journey Context:
LLMs exhibit a U-shaped attention curve, paying less attention to the middle of long contexts. Simply expanding the context window does not guarantee recall. By structuring context to put the system prompt and immediate task at the poles, and compressing historical data in the middle, you align with the model's attention mechanics and mitigate context rot.

environment: Long-horizon coding tasks, multi-file refactoring · tags: context-rot attention lost-in-the-middle summarization · source: swarm · provenance: https://arxiv.org/abs/2307.03172
