概要
This skill provides a structured framework for technical problem-solving, preventing 'guess-and-check' thrashing by mandating a four-phase process: root cause investigation, pattern analysis, hypothesis testing, and disciplined implementation. It is specifically designed to handle complex bug scenarios, test failures, and integration issues by requiring diagnostic instrumentation and data flow tracing. By following the 'Iron Law' of debugging—no fixes without root cause—this skill ensures that developers address the source of a problem rather than just masking its symptoms, leading to higher first-time fix rates and cleaner codebases.
