SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Systematic debugging helps teams avoid patchy fixes by requiring root-cause investigation before proposing changes. It provides a rigorous four-phase workflow to diagnose bugs, test failures, unexpected behavior, or build failures, and it automatically activates when verification faults occur three times in a row.

Core Features & Use Cases

  • Four-phase discipline: Root Cause Investigation → Pattern Analysis → Hypothesis & Testing → Implementation.
  • Auto-trigger: loads when /coder VERIFY fails 3x consecutively.
  • Broad applicability: for any bug, test failure, unexpected behavior, or build failure across languages and stacks.
  • Guidance and templates: concrete steps for data collection, tracing, and safe, verifiable fixes.

Quick Start

Start by enabling the four-phase debugging workflow and begin with Phase 1 to identify the root cause before proposing fixes.

FAQPage Schema
How do I find the root cause of a bug instead of applying patchy fixes?

To find the root cause of a bug, follow a structured four-phase debugging workflow: Root Cause Investigation, Pattern Analysis, Hypothesis & Testing, and Implementation. This enforces evidence-based data collection and reproducibility before proposing changes.

What is the best way to debug recurring test failures across different codebases?

The best way to debug recurring test failures is using a phased workflow that traces data flow and builds minimal reproductions. This broad approach applies across languages and stacks, ensuring staged validation to verify fixes before deployment.

How do I troubleshoot build failures when verification checks repeatedly fail?

To troubleshoot build failures after verification checks repeatedly fail, an auto-trigger mechanism activates a structured debugging workflow. It requires identifying the root cause through pattern analysis and hypothesis testing before implementing any fixes.

Can I use a systematic debugging workflow for unexpected behavior in any programming language?

Yes, you can use this systematic debugging workflow for unexpected behavior across diverse codebases and any programming language. It provides concrete steps for tracing data flow and validating fixes regardless of your specific tech stack.

Why does my debugging process fail to prevent bugs from reappearing after deployment?

Debugging fails to prevent recurring bugs when patchy fixes bypass root cause investigation. Enforcing evidence-based data collection, minimal reproductions, and staged validation before deployment ensures the original issue is permanently resolved.

When should I not use a phase-based debugging approach for troubleshooting?

You should not avoid a phase-based debugging approach even for simple issues, as it prevents patchy fixes. However, if verification faults occur three times consecutively, the structured workflow automatically triggers to ensure proper resolution.
