[counterintuitive] more context is always better

Curate context aggressively; place the most critical instructions and retrieved data at the very beginning or end of the prompt, and filter out low-relevance information.

Journey Context:
With the advent of 100k\+ token context windows, developers stuff the prompt with everything available, assuming the model will find the needle in the haystack. Research shows LLMs exhibit severe U-shaped performance curves: they recall information at the start and end of the context very well, but suffer significant degradation for information in the middle. Overloading context with irrelevant data actively harms recall and increases latency and cost.
