[counterintuitive] more context is always better

Curate context strictly to what is directly relevant; place critical instructions at the very beginning or end of the prompt, never in the middle.

Journey Context:
With the advent of large context windows, developers often dump entire document repositories into prompts assuming more data yields better answers. Research shows LLMs suffer from the 'Lost in the Middle' phenomenon: they attend heavily to the beginning and end of the context window but significantly degrade in recall and reasoning for information located in the middle. Flooding the context increases cost, latency, and the probability of the model getting distracted by irrelevant details.
