[counterintuitive] Providing AI with more context always improves output quality for coding tasks

Curate context ruthlessly. Include only directly relevant code and specifications. Put critical information at the beginning and end of the prompt. For large codebases, use retrieval-augmented selection to pick relevant snippets rather than dumping entire files. If the relevant context is buried in 4000 lines of surrounding code, extract just the 50 lines that matter.

Journey Context:
The intuition 'more information = better decisions' works for humans who can skim and filter. It fails for LLMs. Research demonstrates a U-shaped attention curve: models attend well to information at the beginning and end of their context window but degrade significantly on information in the middle. Stuffing context with everything 'just in case' actively hurts performance because the model distributes attention across all tokens and cannot filter noise as effectively as a human scanning code. The practical impact is counterintuitive: an AI with 50 lines of carefully selected context often outperforms the same AI with 5000 lines that include those same 50 lines buried in the middle. The tradeoff is between completeness and signal-to-noise ratio—and for LLMs, the ratio matters more than the raw amount.
