How to Effectively Debug When You No Longer Understand the Code
Medium
The article outlines how to debug production issues by guiding coding agents using runtime evidence from three investigations. It focuses on three problem types: latency regression, memory leak, and kernel-level hang. The workflow changes to separating facts from hypotheses, using a control for comparison, and validating the suspected cause against all known constraints.
Why it matters
The article describes three production investigations—latency regression, memory leak, and kernel-level hang—to show how to guide coding agents using runtime evidence. It emphasizes separating facts from hypotheses, comparing against a control, and verifying causes against all known constraints.
