# Screenshot Analyzer Implementation

## Overview
I've implemented a comprehensive screenshot analysis tool using Playwright and integrated it into the MetaBuilder platform.

## What Was Created

### 1. Playwright Screenshot Script (`scripts/capture-screenshot.ts`)
A standalone TypeScript script that:
- Launches a headless Chromium browser
- Navigates to the running application (localhost:5000)
- Waits for the page to fully load and stabilize
- Captures a full-page screenshot
- Saves the HTML source for analysis
- Extracts page metadata (title, URL, content preview)

**Usage:**
```bash
npm run screenshot
```

This command will:
1. Install Chromium browser (if not already installed)
2. Run the capture script
3. Generate two files:
   - `screenshot.png` - Full page screenshot
   - `page-source.html` - Complete HTML source

### 2. Screenshot Analyzer Component (`src/components/ScreenshotAnalyzer.tsx`)
An interactive React component integrated into Level 5 (Super God) that provides:

**Features:**
- **Live Screenshot Capture**: Captures the current page state in the browser
- **AI-Powered Analysis**: Uses the Spark LLM API to analyze the page and provide:
  - Summary of page functionality
  - Identification of key UI elements
  - Potential issues and improvements
  - Overall design and functionality assessment
- **Download Capability**: Save screenshots locally
- **Re-analysis**: Re-run AI analysis on captured screenshots
- **Page Information Display**: Shows metadata including:
  - Page title
  - Current URL
  - Viewport dimensions
  - User agent

**How to Access:**
1. Log in as a Super God user (username: `supergod`, default password: `temp123`)
2. Navigate to Level 5
3. Click the "Screenshot" tab in the main navigation

## Integration Points

### Added to Level 5 Navigation
The Screenshot Analyzer is now available as a new tab in the Level 5 interface:
- **Tenants** - Manage multi-tenant instances
- **God Users** - View god-level users
- **Power Transfer** - Transfer super god privileges
- **Preview Levels** - Preview different application levels
- **Screenshot** ← NEW - Capture and analyze the application

## Technical Details

### Dependencies Used
- `playwright` - Browser automation for screenshot capture
- `@phosphor-icons/react` - Icons (Camera, Eye, Download, ArrowsClockwise)
- Spark LLM API (`spark.llm`) - AI analysis of captured pages
- shadcn/ui components - Cards, Buttons, Badges for UI

### AI Analysis Prompt
The analyzer sends the following information to the LLM:
- Page title
- Current URL
- Viewport dimensions
- First 3000 characters of body text
- First 2000 characters of HTML structure

The LLM provides:
1. Page functionality summary
2. Key UI elements identified
3. Potential issues or improvements
4. Overall design/functionality assessment

## Use Cases

1. **Development & Debugging**
   - Capture current application state
   - Get AI feedback on UI/UX
   - Identify potential issues

2. **Documentation**
   - Generate screenshots for documentation
   - Automated visual testing reference

3. **Quality Assurance**
   - Visual regression testing
   - Cross-environment comparison
   - Accessibility analysis via AI

4. **Design Review**
   - Get AI-powered design critiques
   - Identify UX improvements
   - Analyze layout and composition

## Future Enhancements

Potential improvements that could be added:
- **Scheduled Screenshots**: Automatic captures at intervals
- **Comparison Tool**: Compare screenshots across time/versions
- **Element Highlighting**: Click elements for focused analysis
- **Multi-page Capture**: Screenshot entire user flows
- **Export to PDF**: Generate PDF reports with screenshots and analysis
- **Integration with CI/CD**: Automated screenshot testing in GitHub Actions

## Files Modified

1. `/workspaces/spark-template/scripts/capture-screenshot.ts` - NEW
2. `/workspaces/spark-template/src/components/ScreenshotAnalyzer.tsx` - NEW
3. `/workspaces/spark-template/src/components/Level5.tsx` - Modified (added tab)
4. `/workspaces/spark-template/package.json` - Modified (added npm script)

## Notes

- The standalone Playwright script runs externally and requires the dev server to be running
- The integrated Screenshot Analyzer component works within the browser context
- Both approaches complement each other for different use cases
- Playwright must be installed with Chromium browser support (`@playwright/test` package)
