[counterintuitive] Bigger context windows mean you should put everything in the prompt

Curate context aggressively; place the most important information at the beginning or end of the prompt, and use retrieval to fetch only highly relevant chunks rather than dumping entire documents.

Journey Context:
With 100k\+ context windows, developers often stuff the entire codebase or document set into the prompt. However, models suffer from the Lost in the Middle phenomenon: they attend poorly to information located in the middle of long contexts. Furthermore, irrelevant context degrades performance by increasing the signal-to-noise ratio, causing the model to latch onto distracting details. A targeted, well-ordered 5k context will outperform a noisy 100k context.
