Can I use this for software debugging as well as hardware?

Absolutely. While it includes engineering standards, the methodology is universal and effective for investigating software regressions, system outages, and process failures.

What is the quality scoring rubric?

The skill evaluates every analysis on six dimensions, including causal logic, evidence basis, and actionability, scoring each from 1 to 5 to ensure a rigorous investigation.

What is the Five Whys analysis skill?

It is a specialized diagnostic capability for Claude that helps users identify the underlying causes of problems through structured, iterative questioning and logical validation.

How does the reporting feature work?

Once the analysis is complete, the skill uses a local Python script to generate standardized HTML and JSON reports, providing a professional audit trail of the investigation.

Does this skill support industry standards like ISO 26262?

Yes, the skill includes integration for validating proposed root causes against documented failure patterns from standards such as ISO 26262 and the AIAG-VDA FMEA Handbook.
