[counterintuitive] more context always improves LLM accuracy

Curate context ruthlessly. Put critical information at the beginning or end of the prompt window, and use retrieval metrics to ensure only highly relevant chunks are injected.

Journey Context:
Developers stuff context windows thinking more information gives the model more to work with. However, LLMs suffer from the 'Lost in the Middle' effect. When context windows are filled with irrelevant or marginally relevant information, performance on retrieving/synthesizing facts from the middle of the context drops significantly compared to shorter, highly targeted contexts. Noise degrades attention.
