[counterintuitive] Should I put all relevant documents into the LLM context window

Curate context aggressively; place critical information at the very beginning or end of the prompt, and use map-reduce or chunking strategies rather than dumping massive text blocks.

Journey Context:
Developers maximize context window usage, assuming the model attends equally to all tokens. Research \('Lost in the Middle'\) proves LLMs exhibit U-shaped attention: they recall information at the start and end of the context much better than the middle. Overloading context dilutes the attention mechanism, increases latency/cost, and actively degrades performance on the target task.
