SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill systematically diagnoses bugs and errors by tracing code, forming hypotheses, and identifying root causes, saving developers significant debugging time.

Core Features & Use Cases

  • Hypothesis-Driven Debugging: Employs a structured approach to pinpoint the origin of issues.
  • Codebase Analysis: Searches code, traces data flow, and analyzes recent changes to find bugs.
  • Root Cause Identification: Clearly articulates the underlying problem and provides evidence.
  • Use Case: When encountering an unexpected error message or a feature not working as intended, use this Skill to get a detailed diagnosis and recommended fix.

Quick Start

Use the debug-issue skill to diagnose the error 'TypeError: Cannot read property "name" of undefined' in the user authentication module.

FAQPage Schema
How do I diagnose a complex bug using hypothesis-driven debugging?

Hypothesis-driven debugging systematically diagnoses complex bugs by analyzing symptoms, tracing data flow, formulating hypotheses, and testing them against code changes to pinpoint the root cause. It provides a clear diagnosis with recommended fixes.

What is the best way to find the root cause of an unexpected error in my codebase?

The best way to find a root cause is analyzing error symptoms and tracing relevant code sections via search and version control history. This approach examines recent code changes to articulate the underlying problem and provide evidence.

Can I trace data flow to troubleshoot a TypeError in an authentication module?

Yes, you can trace data flow to troubleshoot a TypeError by analyzing how data moves through the authentication module. The method locates relevant code sections, forms hypotheses about undefined properties, and tests them to resolve the error.

Does this debugging approach work for analyzing recent code changes in version control?

Yes, this debugging approach works for analyzing recent code changes by examining version control history. It searches code, traces data flow, and analyzes recent modifications to identify what introduced the bug and formulate a clear diagnosis.

When should I use systematic root cause analysis instead of manual bug fixing?

You should use systematic root cause analysis instead of manual bug fixing when encountering unexpected errors or features not working as intended. It saves significant debugging time by providing a structured, hypothesis-driven methodology for complex software issues.
