Developers often treat LLM‑driven coding as a speed hack, spitting out rough patches and merging unchecked pull requests. The author argues the opposite: use the same models to produce higher‑quality code, even if it slows the cycle. Recent public models from Anthropic and OpenAI demonstrate enough reasoning power to surface subtle bugs rather than just generate boilerplate for review tasks.

Building on that insight, the author created a Claude sub‑agent that runs alongside Codex and Cursor Bugbot to audit a pull request. Each tool flags issues classified as critical, high, medium or low, then the developer validates false positives and drafts a final report. In practice the pipeline uncovers dozens of defects while keeping hallucinations near zero for future maintenance.

This slower, bug‑centric workflow rarely boosts raw throughput; instead it forces engineers to confront legacy flaws and write targeted unit tests. The author admits token costs rise and some PRs are abandoned when critical issues dominate, but the resulting codebase is healthier and easier for subsequent developers to understand. The method transforms LLMs from speed tools into quality assistants daily.
