What This Skill Does

A structured debugging workflow that enforces root cause analysis before any fix is applied. It runs four phases: investigate, analyze, hypothesize, implement. The core rule is simple: no code changes until the root cause is confirmed.

Instead of patching symptoms and creating whack-a-mole bugs, this enforces a confirmed root cause before touching any code, which means fixes actually stick.

When to use it

  • Tracing why a regression appeared after a recent commit
  • Debugging intermittent failures that only show up in staging
  • Finding the root cause of a null reference before patching it
  • Running a structured post-mortem on a bug that keeps coming back
  • Diagnosing configuration drift between local and production environments
