[counterintuitive] more context window always improves accuracy

Place critical information at the very beginning or end of the prompt context; aggressively prune irrelevant context to avoid the 'lost in the middle' effect.

Journey Context:
With the rise of massive context windows, developers stuff prompts with all available data assuming more information yields better answers. Research demonstrates the 'lost in the middle' phenomenon: LLMs effectively ignore information located in the middle of long contexts. More context also increases latency, cost, and the chance of conflicting information causing confusion. High-signal, well-ordered context consistently outperforms exhaustive context.
