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

Curate context strictly to what is relevant. Use retrieval metrics to evaluate context quality, not just quantity, and place critical information at the beginning or end of the prompt.

Journey Context:
Developers stuff the prompt with entire documents or long histories, assuming the model will find the needle. Research shows LLMs suffer from the 'Lost in the Middle' phenomenon where they ignore information in the middle of long contexts. Irrelevant context actively degrades reasoning and increases latency/cost without improving accuracy.
