A benchmark study compared two AI coding agent patterns for fixing multi-module bugs. The "Solo Executor Loop" pattern involved iterative editing and retrying, while the "Advisor Blueprint Routing" pattern used an initial architectural blueprint to guide a single-pass implementation. The Advisor Blueprint Routing pattern significantly outperformed the Solo Executor Loop, reducing LLM calls by half, cutting input tokens by over 84%, and speeding up execution by 1.78x, all while maintaining a perfect score on the grading suite.
