SYSTEM DOCUMENTATION & REQUIREMENTS

## What problem does it solve? Screenshot-obsessed QA work is error-prone when visual fidelity is assumed without evidence. This Skill codifies a skeptical, evidence-first approach to QA, requiring visual proof for every claim and guiding testers through a repeatable reality-check process.

## Core Features & Use Cases

Visual evidence capture using automated screenshots to verify UI against specifications.
Stepwise QA workflow: reality checks, visual analysis, and interactive testing to identify gaps.
Generates structured observations and test results suitable for stakeholder review.

### Quick Start Initiate the reality-check workflow by capturing UI screenshots and reviewing the resulting test data.

FAQPage Schema

How do I capture automated screenshots for UI testing using Playwright?▼

Automated screenshots for UI testing using Playwright are captured through a deterministic workflow that performs visual captures, checks component interactions, and logs issues to guide remediation.

What is an evidence-first approach to visual QA testing?▼

An evidence-first approach to visual QA testing requires visual proof for every claim through automated screenshots, codifying a skeptical verification process that checks UI implementations against specifications.

How do I verify UI implementations match specifications across different devices?▼

To verify UI implementations match specifications across different devices, you can run cross-version validation that captures automated visual evidence and logs discrepancies to guide remediation.

Can I use Playwright for component interaction checks and cross-version validation?▼

Yes, you can use Playwright for component interaction checks and cross-version validation across devices, as it supports a deterministic workflow for capturing visual evidence and generating structured observations.

What is the best way to generate structured test results for stakeholder review from UI QA?▼

The best way to generate structured test results for stakeholder review from UI QA is to execute a stepwise workflow that performs reality checks, visual analysis, and interactive testing to produce evidence-rich reports.

Why does visual fidelity testing fail without screenshot evidence?▼

Visual fidelity testing fails without screenshot evidence because assuming visual accuracy is error-prone, requiring automated visual captures to ensure implementations match specifications and identify gaps.
