[counterintuitive] more context window usage improves accuracy

Place the most critical instructions and retrieved documents at the very beginning or end of the prompt context window; aggressively prune irrelevant context.

Journey Context:
Developers often stuff the context window with as much information as possible, assuming more data leads to better reasoning. Research shows LLMs suffer from Lost in the Middle degradation. Model performance follows a U-shaped curve: they recall information at the very beginning and end of the context well, but accuracy drops significantly for information buried in the middle. Excessive context also increases attention complexity and latency without proportional accuracy gains.
