[counterintuitive] more context window usage improves accuracy

Keep retrieved context strictly minimal and highly relevant; use techniques like reranking and chunking to avoid Lost in the Middle effects.

Journey Context:
Developers stuff the context window thinking more information equals better answers. Research shows LLMs suffer from the 'Lost in the Middle' phenomenon, where they ignore information placed in the middle of long contexts. More context also increases latency, cost, and the chance of conflicting instructions degrading performance. Targeted, concise context consistently outperforms exhaustive context dumping.
