[counterintuitive] More context is always better

Place the most critical information at the very beginning or end of the prompt context; aggressively prune irrelevant context rather than stuffing the prompt.

Journey Context:
With the rise of large context windows, developers stuff as much data as possible into prompts. However, models exhibit a U-shaped performance curve: they attend heavily to the beginning and end of the context window but ignore or forget information in the middle. Adding more context increases cost and latency while actively degrading accuracy if crucial facts are buried in the middle.
