SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Systematic debugging with a structured root-cause investigation workflow that prevents guessing and accelerates fixes by following a disciplined, phased approach.

Core Features & Use Cases

  • Four-phase workflow: investigate, analyze, hypothesize, implement to ensure thorough root-cause analysis.
  • Guardrails and hooks: integrated checks and prompts to keep debugging disciplined and auditable.
  • Real-world scenarios: effective for errors, 500s, stack traces, and elusive bugs where the root cause is unclear.

Quick Start

Run the investigate skill on a failing workflow to begin root-cause analysis.

FAQPage Schema
How do I find the root cause of a 500 error or stack trace?

To find the root cause of a 500 error or stack trace, you can use a structured investigation workflow that applies a four-phase process to trace origins in failing software. This prevents guessing by applying disciplined, phased analysis.

What is the best way to debug elusive bugs across a codebase?

The best way to debug elusive bugs across a codebase is following a systematic root-cause investigation workflow. This approach replaces guessing with a disciplined, phased process to ensure thorough analysis and accelerate fixes.

How does a phased debugging workflow operate?

A phased debugging workflow operates through four distinct phases: investigate, analyze, hypothesize, and implement. It uses pre-defined hooks and tool integrations to keep troubleshooting disciplined and auditable across the codebase.

Can I use structured troubleshooting for performance anomalies?

Yes, you can use structured troubleshooting for performance anomalies. The systematic investigation workflow applies to errors, stack traces, and performance issues to identify and trace root causes effectively.

Do I need specific tools to start a root-cause investigation?

You do not need specific external dependencies to start a root-cause investigation. The workflow operates independently with integrated checks and prompts to maintain debugging discipline without requiring additional tool installations.

Why should I use a structured investigation instead of ad-hoc debugging?

You should use a structured investigation instead of ad-hoc debugging to prevent guessing and accelerate fixes. The phased approach provides guardrails and integrated checks that keep the debugging process disciplined and auditable.
