Standardizes visual audits, responsive design, and behavioral testing for web apps. Use to verify a web UI fix or cross-browser behavior; defer backend API refactors, Playwright installation/tooling setup, and Appium/mobile automation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 🌐 Web Visual & Behavioral Testing ## **Priority: P1 (HIGH)** > [!IMPORTANT] > **Tier 2 (Methodology)**: Strategy web UI/UX audit. > **Tier 3 (Domain)**: Responsive, A11y (WCAG), Browser Engine quirk. ## 🧪 Testing Mindset (Comparative Audit) Visual test best as **Comparative Audit** loop: 1. **Baseline (Before)**: Capture `snapshot --aria` + `screenshot` prod/main. 2. **Implementation (After)**: Capture same local/feature. 3. **Audit**: Compare state for regression, CLS, Aria drift. Responses must label the two captures as **Before** and **After** (or Baseline and Fixed) and include the diff and neighboring-element side-effect check. ## 📋 Scenario Matrix | Change Type | Scenarios to Run | | :---------------- | :------------------------------------------------- | | **CSS/Layout** | Responsive Audit + Hover + CLS Check | | **Forms/Input** | Validation Msg + Focus State + Error Boundary | | **Navigation** | URL Sync + Sticky Header + Back-Button Persistence | | **Assets/Fonts** | Lazy Load + Icon Check + LCP Audit | …

How to install
mdr add hoangnguyen0403/agent-skills-standard/common-web-visual-testing@sha256:b1fcb6946f90838bThe line at the top of this page pins the label git:20261030.a5465a6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
