SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents guess-and-check debugging by enforcing a systematic process for identifying root causes before implementing fixes, reducing wasted effort and regressions.

Core Features & Use Cases

  • Root Cause Investigation: Guides analysis of errors, reproduction steps, recent changes, data flow, and multi-component failures before proposing solutions.
  • Hypothesis-Driven Debugging: Applies evidence-based testing, minimal changes, and verification to isolate the actual cause of unexpected behavior.
  • Use Case: When a production API fails with a deep stack trace, use this Skill to trace the bad input backward through system layers and identify the originating issue instead of patching symptoms.

Quick Start

Use the debug skill to investigate this failing test and identify the root cause before suggesting any fixes.

FAQPage Schema
How do I find the root cause of a test failure before applying a fix?

To find the root cause of a test failure, systematically gather evidence, analyze reproduction steps, and test hypotheses to isolate the originating issue instead of patching symptoms.

What is hypothesis-driven debugging for production issues?

Hypothesis-driven debugging is a process that applies evidence-based testing and minimal changes to verify the actual cause of unexpected behavior in production issues.

What is the best way to debug multi-component integration failures?

The best way to debug multi-component integration failures involves tracing bad inputs backward through system layers, analyzing data flow, and verifying hypotheses to prevent regressions.

How do I investigate build problems using systematic troubleshooting?

Investigate build problems using systematic troubleshooting by gathering evidence, testing hypotheses about recent changes, and verifying the root cause before implementing any fixes.

Why does patching symptoms cause regressions during bug analysis?

Patch symptoms cause regressions during bug analysis because guess-and-check fixes bypass root cause identification, failing to resolve the actual originating issue across system layers.

When do I need root cause investigation for performance issues?

You need root cause investigation for performance issues when unexpected behavior occurs, requiring systematic evidence gathering and hypothesis testing to identify the true bottleneck.
