[counterintuitive] Should I include all available context in the LLM prompt

Curate context strictly to what is relevant. Use techniques like reordering relevant information to the beginning or end of the prompt context, because performance degrades significantly as irrelevant context length increases.

Journey Context:
Developers dump entire documents or massive histories into prompts thinking more information always equals better answers. LLMs suffer from 'attention dilution' or the 'lost in the middle' phenomenon where they ignore information placed in the middle of long contexts. A shorter, highly relevant prompt often outperforms a massive context window filled with noise.
