[counterintuitive] more context window better performance

Optimize context for relevance and density. Place critical information at the very beginning or end of the prompt context window. Filter out low-signal context aggressively.

Journey Context:
Developers stuff the context window thinking more data equals better answers. Research shows LLMs have a U-shaped attention curve \(primacy and recency bias\). Irrelevant context degrades performance and increases latency and cost. A smaller, highly relevant context window outperforms a massive, noisy one.
