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

Curate context aggressively; retrieve only the top-k most relevant chunks and prioritize signal-to-noise ratio over sheer volume to avoid 'lost in the middle' degradation.

Journey Context:
Developers dump massive top-k retrievals into prompts assuming more info prevents guessing. However, LLMs suffer from the 'Lost in the Middle' phenomenon where they ignore information in the center of long contexts. Irrelevant context increases attention complexity and distracts the model, degrading reasoning and increasing hallucination rates.
