SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps developers and practitioners systematically diagnose and resolve bugs, unexpected behavior, and regressions in code that has already been implemented by forcing an evidence-first, root-cause approach before any fixes are written.

Core Features & Use Cases

  • Evidence-first diagnosis: Trace code paths, cite file:line, inspect logs, and avoid guessing; use 5 Whys and causal diagrams to reach a verifiable root cause.
  • UI diagnostic tooling: Produce copy-paste browser DevTools scripts for visibility, stacking context, overflow, and interaction tracing when the bug is UI-related.
  • Developer-as-sensor workflow: Minimize runtime assumptions by asking targeted, minimal actions of the developer to collect the exact runtime evidence needed.
  • Verified fixes and verification: Provide a clear fix plan, apply changes at the root cause, and produce verification steps or scripts to confirm the problem is resolved.

Quick Start

Describe the failing behavior, include reproduction steps, affected file paths, and any logs or screenshots so the diagnostic trace can begin.

Frequently Asked Questions about spx-vibe

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

FAQPage Schema
How do I find the root cause of a bug in implemented code?▼

To find the root cause of a bug, apply an evidence-first approach using code tracing, file and line citations, and 5-Whys causal analysis. This ensures you reach a verifiable root cause before writing any fixes.

What is the best way to debug UI failures and interaction issues?▼

The best way to debug UI failures is to generate copy-paste browser DevTools scripts that trace visibility, stacking context, overflow, and interactions to collect exact runtime evidence.

How do I fix flaky production issues without guessing?▼

Fix flaky production issues by using a developer-as-sensor workflow that minimizes runtime assumptions and collects targeted evidence like logs and code paths to confirm the root cause.

Can I use 5 Whys analysis for software bug diagnosis?▼

Yes, you can use 5 Whys analysis for software bug diagnosis to perform systematic causal analysis, trace code paths, and identify the exact root cause of reported regressions or logic failures.

How do I verify a bug fix after applying changes to the root cause?▼

Verify a bug fix by following the provided verification steps and scripts that confirm the applied changes have successfully resolved the unexpected behavior at the root cause.
