Report #50618

[counterintuitive] Dumping entire codebases or massive documents into the context window 'just in case' the model needs it

Aggressively retrieve and inject only the specific, relevant snippets \(RAG\) needed for the immediate step, keeping the context lean and highly relevant.

Journey Context:
Early folklore assumed bigger context = better reasoning because early models had tiny contexts. Modern models have massive contexts \(128k-2M\), but suffer from 'lost in the middle' phenomena and attention dilution. A massive, uncurated context increases latency, cost, and the probability of the model latching onto irrelevant details or outdated code. Lean, highly relevant context yields better instruction following and more accurate code generation.
