SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill acts as your first-line technical support, automatically diagnosing errors (build failures, test crashes, runtime issues) and guiding you or attempting fixes, so you don't need to be an expert debugger.

Core Features & Use Cases

  • Automatic Error Diagnosis: Analyzes error messages, console logs, and git status to pinpoint the root cause of failures.
  • Guided Fixes & Escalation: Provides step-by-step solutions for common issues and intelligently escalates complex problems to avoid wasted time.
  • Use Case: When your app shows a blank screen or tests fail mysteriously, just say "it's broken" or "help me fix this error". This Skill will investigate, explain the issue in plain language, and either apply a fix or create a clear report for further help.

Quick Start

Say "my build is failing, what's wrong?" to automatically analyze the error logs and propose a solution.

Frequently Asked Questions about troubleshoot

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

FAQPage Schema
How do I diagnose why my build is failing?

Build failures are diagnosed by analyzing error logs, environment checks (node, npm versions), and dependency verification. This Skill automatically examines console output and git status to pinpoint root causes—missing modules, type errors, or configuration issues—then proposes fixes or escalates complex problems.

What should I do when my web app shows a blank screen or white screen?

A blank or white screen typically signals runtime errors, missing dependencies, or UI rendering failures. This Skill investigates runtime logs, checks for module resolution problems, and guides you through step-by-step fixes or provides a diagnostic report for further troubleshooting.

Can this help with Node.js project errors and test failures?

Yes. This Skill handles Node.js runtime issues, build failures, test crashes, and form submission problems. It performs environment checks, analyzes error messages and console logs, then either applies automated fixes or creates clear escalation workflows for complex issues.

Do I need debugging expertise to fix errors with this tool?

No. This Skill acts as first-line technical support, automatically diagnosing errors and providing plain-language explanations. It handles common issues across build, runtime, and UI layers without requiring expert debugger knowledge or manual log analysis.

What types of errors can this Skill identify and resolve?

This Skill diagnoses build failures, runtime errors, test crashes, type errors, missing modules, non-responsive UI, form submission failures, and white screen issues. It performs dependency verification and automated remediation, then escalates problems that need deeper investigation.

How does error diagnosis work across web and Node.js projects?

Diagnosis spans build, runtime, and user-interface layers by analyzing error messages, console logs, environment configuration (node, npm, git status), and dependencies. The Skill identifies root causes of failures, proposes targeted fixes, and guides remediation for web and Node.js applications.
