[counterintuitive] Should I include as much context as possible in the prompt

Put the most important information at the very beginning or very end of the prompt context. Limit retrieved documents to the minimum necessary to answer the query.

Journey Context:
Developers stuff prompts with dozens of retrieved chunks thinking more info equals better reasoning. Research shows LLMs suffer from 'lost in the middle' degradation; they attend heavily to the start and end of the context window, ignoring or forgetting information in the middle. More context increases latency, cost, and the surface area for distraction, leading to worse performance than a leaner prompt.
