How do I trigger a root cause analysis?

You can use the /why command followed by a description of the issue or symptom you want to investigate.

What is the purpose of the Kaizen Why skill?

It automates the Five Whys technique to help developers find the fundamental root cause of problems instead of just fixing surface-level symptoms.

Does it always require exactly five steps?

No, five is a rule of thumb. The skill helps you continue the investigation until you reach a systemic or process-level issue that can be addressed effectively.

Why is this better than standard debugging?

Standard debugging often results in a 'patch' for a specific bug, whereas the Why skill focuses on 'systemic' fixes that prevent entire classes of bugs from recurring.

Can it handle complex issues with multiple causes?

Yes, the skill supports multi-branch analysis, allowing you to explore different contributing factors separately to find multiple root causes.

Productivity & Workflow

Conducts iterative Five Whys root cause analysis to uncover systemic issues and propose fundamental solutions.

The Kaizen Why skill implements the structured Five Whys methodology within Claude Code to help developers move beyond surface-level symptoms and identify the foundational causes of technical or process-related failures. By iteratively questioning why an event occurred, it facilitates the discovery of systemic flaws—such as missing validations, outdated documentation, or suboptimal CI/CD configurations—and provides actionable solutions that prevent issue recurrence rather than just applying temporary patches. It is an essential tool for post-mortems, debugging complex race conditions, and improving engineering workflows.
