SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Systematic debugging with root-cause investigation to prevent fixing symptoms and to deliver durable fixes.

Core Features & Use Cases

It guides users through four phases (investigate, analyze, hypothesize, implement) to gather symptoms, read code, form testable hypotheses, lock scope, and implement verifiable remedies, with proactive guidance when errors appear.

Quick Start

Explain the issue to the AI and start the four-phase root-cause investigation to identify the root cause before applying a fix.

FAQPage Schema
What is the best way to find the root cause of a software bug?

A structured root-cause investigation prevents fixing symptoms by guiding you through four phases: investigate, analyze, hypothesize, and implement. It enforces evidence collection and hypothesis testing to deliver durable, regression-ready fixes for software issues.

How do I debug a code issue without just patching the symptoms?

To debug without patching symptoms, follow a structured investigation that gathers evidence, reads code, forms testable hypotheses, and locks scope. This method ensures you verify the root cause before applying a regression-ready fix with proper testing and documentation.

How does a structured root-cause investigation work for software services?

Structured root-cause investigation works across code, services, and scripts by progressing through four phases: investigate symptoms, analyze code, hypothesize testable root causes, and implement verifiable remedies. This enforces evidence collection and regression-ready changes.

Can I use systematic debugging for scripts and production services?

Yes, systematic debugging can be applied to debugging tasks across code, services, and scripts. It scales from simple script errors to complex service issues by enforcing evidence collection, hypothesis testing, and verifiable fixes regardless of the environment.

What should I do if my software debugging keeps hitting dead ends?

If your software debugging hits dead ends, enforce a structured investigation to gather symptoms and form testable hypotheses. The process provides proactive guidance when errors appear, ensuring you lock scope and identify the root cause before implementing a fix.
