SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Diagnosing root causes in complex Cortex deployments is hard and error-prone; this skill provides a structured, read-only 5 Whys analysis workflow to identify root causes without touching code.

Core Features & Use Cases

  • Structured 5 Whys analysis tailored to the Cortex stack (Express + JS + PostgreSQL + React/Vite).
  • Flow-trace-oriented reasoning that cites exact files and lines for each Why step.
  • Comprehensive documentation of root cause, blast radius, edge cases, and verification steps.
  • Use case: a bug in the Cortex monorepo where a symptom persists across services; you generate a root-cause analysis to guide fixes without editing code.

Quick Start

Provide a structured, read-only root-cause analysis for a Cortex bug using 5 Whys, with evidence-linked steps and no code changes.

FAQPage Schema
How do I perform a 5 Whys root-cause analysis for bugs in an Express and PostgreSQL monorepo?

A 5 Whys root-cause analysis for an Express and PostgreSQL monorepo identifies structural issues by tracing symptoms through logs and tests, citing specific files and queries for each step without modifying code. It stops when a structural root cause is reached.

What is the best way to diagnose persistent bugs across services in a React Vite and Express stack?

Diagnosing persistent bugs across services in a React Vite and Express stack requires a structured 5 Whys analysis to trace symptoms back to a structural root cause, documenting the blast radius and verification steps without touching code.

Can I investigate PostgreSQL query failures in a monorepo without modifying code?

You can investigate PostgreSQL query failures in a monorepo without modifying code by applying a read-only 5 Whys analysis workflow that cites exact data observations, queries, and line numbers to substantiate the diagnostic steps.

Does 5 Whys analysis work for tracing test failures and log symptoms to a structural root cause?

5 Whys analysis works for tracing test failures and log symptoms to a structural root cause by flow-tracing evidence through exact files and line numbers, ensuring each diagnostic step is substantiated by specific data observations from the Cortex stack.

What are the limitations of using a read-only diagnostic workflow for Cortex bug analysis?

The limitation of a read-only diagnostic workflow for Cortex bug analysis is that it strictly identifies the structural root cause and documents edge cases without modifying code, meaning developers must implement the actual fixes separately based on the generated analysis.
