SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

Runtime-guard eliminates the time-consuming process of manually hunting frontend runtime problems by performing systematic checks and producing prioritized remediation steps, so developers recover working local or deployed builds faster.

Core Features & Use Cases

  • Comprehensive Diagnostics: Verifies dev server status, port conflicts, dependency integrity, build artifacts, and configuration files across common stacks (React, Docusaurus, Vite, Webpack).
  • Runtime Error & Asset Validation: Scans for console errors, missing index.html/root mounting issues, broken imports, asset 404s, MIME and font issues, and SPA routing problems.
  • Network, Environment & Build Checks: Inspects API connectivity and CORS, validates environment variables, and checks base path/output settings with safe automatic fix suggestions and clear manual remediation steps.
  • Use Case: When a Docusaurus site shows a blank page after pulling new code, runtime-guard locates broken imports, missing env values, or port conflicts and recommends safe fixes and verification steps.

Quick Start

Use the runtime-guard skill to analyze the project, produce a structured diagnostic report, and suggest safe automatic fixes.

Frequently Asked Questions about runtime-guard

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

FAQPage Schema
How do I diagnose a blank page in Docusaurus after pulling new code?▼

Diagnose frontend runtime failures by checking dev server status, dependency integrity, and index.html mounting. The skill produces a structured report detailing port conflicts, asset 404s, and routing problems with remediation steps.

How do I fix Webpack or Vite dev server port conflicts and unresponsive endpoints?▼

Fix Webpack or Vite dev server issues by verifying port availability and server responses. The skill inspects network connectivity and configuration files, then suggests safe automated corrections to restore server functionality.

Does this diagnostic tool work with React and Docusaurus build environments?▼

Yes, this diagnostic tool works with React, Docusaurus, Vite, and Webpack projects. It validates dependency integrity, package-lock files, and build artifacts across these specific development and build environments to resolve runtime errors.

Why does my Vite build show asset 404 errors and broken imports?▼

Vite build asset 404 errors and broken imports occur due to incorrect base path or output settings. The skill scans for missing asset imports, validates MIME and font issues, and checks build configurations to recommend fixes.

What is the best way to resolve SPA routing configuration problems?▼

The best way to resolve SPA routing problems is through systematic configuration checks. The skill inspects routing setups, validates environment variables, and identifies network or CORS issues to propose safe manual remediation steps.
