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

Optimize for signal-to-noise ratio. Use chunking, relevance scoring, and context window trimming. Strip boilerplate and irrelevant data before passing to the LLM to avoid the 'lost in the middle' degradation.

Journey Context:
Developers dump entire documents or massive histories into prompts thinking more data equals better answers. Empirical evidence shows 'lost in the middle' phenomena: LLMs fail to retrieve information located in the middle of long contexts. Excessive context increases latency, cost, and degrades accuracy due to attention dilution, making the model worse at finding the specific needle it needs.
