Software fundamentals are key to getting good results from AI coding agents

An experienced engineer argues that expertise is what makes AI coding agents shine: knowing what to ask and which instructions to give at each level (architecture, design, implementation) yields more robust results and cuts review effort, while vague high-level goals produce misaligned output. Quoting Jarred Sumner's real prompts for perf work with Claude: rewrite with data-oriented design, replace hash tables with flat arrays and pack hot data into index bits, "caching is cope for a slow design—delete caches and redesign for speed," and SoA-vs-AoS checks. Software engineering fundamentals remain the differentiator.
