SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill guides the agent to work through a bug methodically — distinguishing the root cause from the symptoms, tracing the execution path that led to the failure, and producing a clear diagnosis with a recommended fix. It applies the 5-Why technique, reads stack traces carefully, and avoids patching the symptom without understanding the cause.

Core Features & Use Cases

  • Systematic root-cause diagnosis using 5-Why analysis and structured execution-path tracing.
  • Stack-trace oriented evaluation to identify the last application-code frame where the bug originates.
  • Clear, actionable diagnosis with symptom, root cause, category, execution path, and recommended fix.
  • Useful for runtime errors, flaky tests, and complex debugging scenarios to reduce guesswork.

Quick Start

Ask the Bug Root Cause Analyzer to diagnose a bug by providing the exact error message and full stack trace.

FAQPage Schema
How do I diagnose a software bug by tracing a stack trace to the root cause?

To diagnose a software bug by tracing a stack trace, you provide the full stack trace, error message, and relevant code context to generate a structured root-cause report. This applies 5-Why analysis to identify the actual origin frame instead of just patching symptoms.

What is the best way to find the root cause of flaky tests and runtime errors?

The best way to find the root cause of flaky tests and runtime errors is systematic execution-path tracing. By evaluating the full stack trace to locate the last application-code frame, you can distinguish the true root cause from observed symptoms and apply a targeted fix.

How do I perform a 5-Why analysis for debugging complex codebases?

To perform a 5-Why analysis for debugging complex codebases, input the exact error message, expected versus observed behavior, and relevant code context. The analysis methodically traces the execution path backwards to pinpoint the underlying cause and recommend an actionable fix.

What information do I need to diagnose runtime errors and identify the root cause?

To diagnose runtime errors and identify the root cause, you need the exact error message, full stack traces, relevant code context, and a description of expected versus observed behavior. These inputs allow the system to trace the execution path and generate a structured diagnosis.

Why does patching a symptom fail to resolve the underlying software bug?

Patching a symptom fails to resolve the underlying software bug because it ignores the execution path that led to the failure. Systematic root-cause diagnosis using 5-Why analysis and stack-trace evaluation is required to identify and fix the actual origin of the issue.
