SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Systematic debugging with root cause investigation. Four phases: investigate, analyze, hypothesize, implement. Iron Law: no fixes without root cause. Use when asked to 'debug this', 'fix this bug', 'why is this broken', 'investigate this error', or is troubleshooting why something stopped working. Provide proactive guidance to gather data, reproduce issues, and validate fixes.

Core Features & Use Cases

  • Structured data collection prompts to reproduce bugs and gather evidence
  • Guided hypothesis generation and validation to identify root causes
  • Stepwise plan to implement fixes with measurable outcomes

Quick Start

Describe the failing behavior and any error messages to begin the guided root-cause investigation.

FAQPage Schema
How do I find the root cause of a software bug systematically?

To find the root cause of a software bug systematically, use a structured debugging workflow that enforces data collection, issue reproduction, and iterative hypothesis validation across four phases: investigate, analyze, hypothesize, implement.

What is the best way to debug runtime errors and unexpected software behavior?

The best way to debug runtime errors is to follow a disciplined root-cause analysis process that prompts structured questions and gathers evidence to reproduce the issue before generating and validating iterative hypotheses.

Why should I investigate a bug before implementing a software fix?

You should investigate a bug before implementing a software fix because a systematic debugging workflow enforces the Iron Law: no fixes without root cause identification, ensuring your solutions are reproducible, documented, and actionable.

How do I start a systematic investigation when troubleshooting why something stopped working?

To start a systematic investigation when troubleshooting why something stopped working, describe the failing behavior and any error messages to trigger guided data collection prompts for reproducing the issue.

Can I use systematic debugging for any software issue or runtime error?

Yes, you can use systematic debugging for software issues, runtime errors, or unexpected behavior, as the guided workflow applies structured questions and iterative hypotheses to diagnose problems across various software engineering contexts.

What are the limitations of fixing bugs without root cause analysis?

Fixing bugs without root cause analysis often leads to unresolved underlying issues, as systematic debugging requires identifying the actual source through data collection and hypothesis validation before implementing a stepwise plan with measurable outcomes.
