[counterintuitive] Should I put all available context into the LLM prompt

Aggressively prune context to strictly relevant information. Place crucial instructions at the very beginning or end of the prompt window.

Journey Context:
With the expansion of context windows, developers stuff prompts with all available data assuming more context yields better reasoning. However, LLMs exhibit a U-shaped performance curve over context length. Irrelevant context acts as noise, degrading accuracy and increasing latency/costs. The model's attention mechanism is diluted across the entire sequence, meaning critical details get lost in the middle. Precision of retrieval matters vastly more than volume of context.
