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.
