The Root Cause Bug Fixer skill transforms how Claude handles errors by moving beyond surface-level symptom chasing to address underlying architectural flaws. It enforces a strict test-driven development (TDD) workflow where a failing regression test must be established before any code is modified, ensuring that bugs are not only fixed at their source but stay fixed. By requiring deep analysis and minimal, targeted code changes, this skill maintains codebase integrity and prevents the introduction of technical debt or unrelated regressions.
