root-cause-analysis

What problem does it solve?

This Skill provides a systematic framework for identifying the true root cause of complex problems, preventing superficial fixes and recurring issues. It guides the user through evidence collection, hypothesis testing, and deep investigation, ensuring that solutions address the underlying problem, leading to lasting resolutions and improved system reliability.

Core Features & Use Cases

• Evidence-Based Investigation: Emphasizes collecting comprehensive data (logs, metrics, traces) to understand the problem.
• Hypothesis-Driven Analysis: Guides forming and testing hypotheses systematically to pinpoint the root cause.
• 5 Whys Technique: Utilizes iterative questioning to drill down to the fundamental reason behind an issue.
• Fishbone Diagram (Ishikawa): Helps categorize potential causes (Man, Machine, Material, Method, Measurement, Environment) for complex problems.
• Use Case: When a critical production service is intermittently failing, use this skill to collect all relevant logs and metrics, form hypotheses about network issues or database contention, and systematically test each one to identify the exact root cause.

Quick Start

Perform a root cause analysis for the intermittent API timeout errors, starting with collecting recent error logs and metrics.
