[counterintuitive] more context is always better

Include only strictly necessary context; prune irrelevant documents and historical turns before sending to the model.

Journey Context:
With 100k\+ context windows, developers stuff the prompt assuming more information reduces hallucination. However, LLMs suffer from attention dilution. Performance degrades significantly when relevant information is buried in a sea of irrelevant text. The model pays less attention to the middle of the context. Less is more: a shorter, highly curated prompt yields better instruction following and factuality than a massive dump of loosely related documents.
