- CMS platforms such as WordPress / Drupal
- Any other web application
Prerequisites
Required
Target website must be running
- Local development server (e.g.,
http://localhost:3000) - Staging environment
- Production environment (for read-only reviews)
- Local development server (e.g.,
Browser automation must be available
- Screenshot capture

Step 1: Information Gathering Phase
1.1 URL Confirmation
If the URL is not provided, ask the user:
Please provide the URL of the website to review (e.g.,
http://localhost:3000)
1.2 Understanding Project Structure
When making fixes, gather the following information:
| Item | Example Question |
|---|---|
| Framework | Are you using React / Vue / Next.js, etc.? |
| Styling Method | CSS / SCSS / Tailwind / CSS-in-JS, etc. |
| Source Location | Where are style files and components located? |
| Review Scope | Specific pages only or entire site? |
1.3 Automatic Project Detection
Attempt automatic detection from files in the workspace:
Detection targets:
├── package.json → Framework and dependencies
├── tsconfig.json → TypeScript usage
├── tailwind.config → Tailwind CSS
├── next.config → Next.js
├── vite.config → Vite
├── nuxt.config → Nuxt
└── src/ or app/ → Source directory
1.4 Identifying Styling Method
| Method | Detection | Edit Target |
|---|---|---|
| Pure CSS | *.css files |
Global CSS or component CSS |
| SCSS/Sass | *.scss, *.sass |
SCSS files |
| CSS Modules | *.module.css |
Module CSS files |
| Tailwind CSS | tailwind.config.* |
className in components |
| styled-components | styled. in code |
JS/TS files |
| Emotion | @emotion/ imports |
JS/TS files |
| CSS-in-JS (other) | Inline styles | JS/TS files |
Step 2: Visual Inspection Phase
2.1 Page Traversal
- Navigate to the specified URL
- Capture screenshots
- Retrieve DOM structure/snapshot (if possible)
- If additional pages exist, traverse through navigation
2.2 Inspection Items
Work through references/visual-checklist.md during inspection and again during post-fix verification.
Layout Issues
| Issue | Description | Severity |
|---|---|---|
| Element Overflow | Content overflows from parent element or viewport | High |
| Element Overlap | Unintended overlapping of elements | High |
| Alignment Issues | Grid or flex alignment problems | Medium |
| Inconsistent Spacing | Padding/margin inconsistencies | Medium |
| Text Clipping | Long text not handled properly | Medium |
Responsive Issues
| Issue | Description | Severity |
|---|---|---|
| Non-mobile Friendly | Layout breaks on small screens | High |
| Breakpoint Issues | Unnatural transitions when screen size changes | Medium |
| Touch Targets | Buttons too small on mobile | Medium |
Accessibility Issues
| Issue | Description | Severity |
|---|---|---|
| Insufficient Contrast | Low contrast ratio between text and background | High |
| No Focus State | Cannot determine state during keyboard navigation | High |
| Missing alt Text | No alternative text for images | Medium |
Visual Consistency
| Issue | Description | Severity |
|---|---|---|
| Font Inconsistency | Mixed font families | Medium |
| Color Inconsistency | Non-unified brand colors | Medium |
| Spacing Inconsistency | Non-uniform spacing between similar elements | Low |
2.3 Viewport Testing (Responsive)
Test at the following viewports:
| Name | Width | Representative Device |
|---|---|---|
| Mobile | 375px | iPhone SE/12 mini |
