[counterintuitive] more context window improves accuracy

Aggressively filter and rank retrieved context before injection; provide only highly pertinent documents and place the most critical information at the beginning or end of the prompt.

Journey Context:
With the expansion of context windows \(e.g., 128k\+ tokens\), developers often stuff as much retrieved text as possible into the prompt. However, research demonstrates the 'Lost in the Middle' phenomenon: LLMs effectively ignore information located in the middle of long contexts. Overloading the context window with low-signal data degrades accuracy, increases latency, and inflates cost, making targeted retrieval strictly superior to brute-force context stuffing.
