[counterintuitive] Bigger context windows eliminate the need for RAG or search

Use the context window for the working state \(scratchpad, current file\), but rely on search/RAG for knowledge retrieval. Keep the active context lean and highly relevant.

Journey Context:
With 100k\+ token windows, developers often dump entire codebases or documents into the prompt. This causes attention dilution: the model spends compute attending to irrelevant code, degrading instruction following and increasing latency and cost. RAG remains superior for precision because it restricts the attention mechanism to only the most relevant chunks, reducing noise and cognitive load on the model. A full context window is a liability, not a feature, unless every token is strictly necessary for the immediate task.
