SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Systematic root-cause debugging for software failures by collecting symptoms, reading code, and validating hypotheses to fix the real issue.

Core Features & Use Cases

  • Phase-based root cause investigation guiding users from symptom collection to verification.
  • Pattern analysis to map bugs to known categories and potential fixes.
  • Structured hypothesis testing and safe, minimal implementations with regression tests.
  • Telemetry and learnings capture to improve future debugging sessions.

Quick Start

Describe the bug scenario and reproduce steps to begin root cause investigation.

Frequently Asked Questions about investigate

High-intent search queries and answers about installing and using this skill.

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

To find the root cause of a software bug, collect symptoms, read repository code, and validate hypotheses against known failure patterns using a structured phase-based investigation workflow.

What is the best way to debug an intermittent crash in my codebase?

Debugging an intermittent crash requires reproducing the failure steps, analyzing code patterns to map the bug to known categories, and testing structured hypotheses to isolate the underlying fault.

How do I systematically debug a 500 error?

Systematically debug a 500 error by collecting symptoms, tracing repository history, and applying pattern analysis to validate hypotheses and implement a safe minimal fix with regression tests.

Do I need reproducible steps to start root-cause debugging?

Yes, root-cause debugging requires reproducible steps along with repository access to collect symptoms, validate hypotheses, and accurately trace the code path triggering the software failure.

Can I use pattern analysis for debugging errors across different projects?

Yes, pattern analysis maps bugs to known categories across different projects, enabling structured hypothesis testing to identify root causes from intermittent crashes to 500 errors.

What should I do if my root cause investigation is not working?

If your root cause investigation is not working, ensure you have repository history access and accurate reproduce steps, then use pattern analysis to re-evaluate known failure categories and test new hypotheses.
