SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Visual bugs can slip through until manual QA or post-release. This skill performs mid-build visual verification by taking screenshots of UI components during construction, not just after, to catch regressions early.

Core Features & Use Cases

  • Capture screenshots of modified UI components to verify layouts and data rendering.
  • Support for common frontend frameworks and routes to map changes to visual artifacts.
  • Use Case: during a design sprint, automatically verify that updated components render correctly across viewport sizes.

Quick Start

Start the dev server and run the live-preview workflow to capture and verify screenshots for the modified UI components.

Frequently Asked Questions about live-preview

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

FAQPage Schema
How do I catch visual regressions in frontend components during the build process?▼

Capture screenshots of modified frontend components during mid-build verification to detect silent UI regressions. This workflow generates verifiable visual artifacts for changed routes and components, catching layout bugs before manual QA.

Does visual regression testing work with React, Vue, and Svelte frontend stacks?▼

Visual regression testing works with React, Vue, Svelte, and other frontend stacks. The workflow maps modified components and routes across these frameworks to capture verifiable visual artifacts during the build process.

What is the best way to verify UI layouts across different viewport sizes during a design sprint?▼

The best way to verify UI layouts across viewport sizes is running a mid-build visual verification workflow. It automatically captures screenshots of updated frontend components to confirm visual fidelity across various screen dimensions during active development.

Do I need Playwright to capture screenshots of modified UI components?▼

A screenshot tool is required to capture UI components, with Playwright recommended. The workflow integrates mid-build to automatically screenshot modified frontend elements and produce verifiable artifacts.

When should I run mid-build visual verification instead of post-build screenshot testing?▼

Run mid-build visual verification when you need to prevent silent UI regressions before they reach manual QA or post-release. Capturing screenshots during construction catches layout and data rendering issues early for modified frontend components.
