SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Systematic debugging with root cause investigation. The Iron Law: no fixes without a root cause, four phases guide you from identifying symptoms to implementing durable solutions.

Core Features & Use Cases

  • Four phases: investigate, analyze, hypothesize, implement.
  • Proactive guidance when users report errors or unexpected behavior.
  • Works across bugs, crashes, and performance anomalies, with structured evidence gathering.

Quick Start

Invoke investigate to start root-cause debugging and guide the user through four phases.

FAQPage Schema
What is root-cause debugging and how does it fix software bugs permanently?

Root-cause debugging enforces the Iron Law: no fixes without a root cause. It guides you through four phases—investigate, analyze, hypothesize, implement—to identify symptoms and apply durable solutions rather than patching surface errors.

How do I troubleshoot unexpected application crashes using a structured debugging process?

Troubleshoot unexpected crashes by invoking a four-phase debugging process: investigate symptoms, analyze collected evidence, hypothesize the failure, and implement a validated fix. It prompts for context and uses built-in tools to reproduce and isolate failures.

Can I use structured debugging for performance anomalies and unexpected software behavior?

Yes, structured debugging works across bugs, crashes, and performance anomalies. It proactively guides you when you report errors, collecting structured evidence to trace, test, and validate fixes for any unexpected software behavior.

How do I reproduce and isolate a failure before implementing a software fix?

Reproduce and isolate failures using built-in tools within the analysis phase. The process enforces structured evidence gathering and hypothesis testing to trace the exact failure point before you implement any code changes.

What is the best way to stop recurring bugs without finding the root cause?

You cannot stop recurring bugs without finding the root cause. This debugging approach enforces the Iron Law—no fixes without a root cause—ensuring you implement durable solutions instead of temporary patches that fail again.

Does systematic debugging require specific dependencies or environments to start?

Systematic debugging requires no external dependencies. You start by invoking the process to guide your root-cause investigation, providing context about the error so it can prompt for evidence and define a repeatable tracing workflow.
