They found that high-quality, condensed documentation (Claude.md) combined with tools for accessing detailed information produced the best results. Simply providing raw documentation access didn't improve performance as much as expected and filled up the context window faster. The study used a comprehensive evaluation framework testing functionality, task requirements, and code quality across three different coding tasks. ## Full article daily.dev links to this article rather than hosting it.
