[counterintuitive] Should I include as much context as possible in the LLM prompt

Optimize for signal-to-noise ratio in context. Include only directly relevant information, placing critical instructions at the beginning or end of the context window.

Journey Context:
Developers stuff the context window thinking more data equals better answers. Research shows LLMs suffer from 'needle in a haystack' degradation and the 'lost in the middle' phenomenon. Irrelevant context increases latency, cost, and distracts the model, significantly reducing accuracy on the core task.
