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

Curate context strictly to what is necessary; use retrieval over long dumps, and place critical instructions at the beginning or end of the prompt.

Journey Context:
Developers dump entire documents or long histories into prompts thinking more info equals better answers. However, models suffer from 'Lost in the Middle' \(attention dilution\), where they ignore information in the middle of long contexts. More context also increases latency, cost, and the probability of conflicting information causing the model to hedge or hallucinate. The model's effective context window for accurate recall is much smaller than its maximum context window.
