Report #58640

[architecture] Stuffing the context window with all retrieved memories causes degraded reasoning

Limit injected memory to the top 3-5 highly scored chunks and place the most critical memories at the very beginning or end of the prompt, avoiding the middle.

Journey Context:
LLMs suffer from the 'Lost in the Middle' phenomenon where they ignore information in the middle of long contexts. Agents often retrieve 10\+ chunks and dump them into the prompt, thinking more context is better. It actually degrades performance. Fewer, highly curated chunks placed at the edges of the prompt yield better instruction following and fact retrieval.
