name: dom-to-markdown description: Convert web pages to clean markdown using OpenClaw's browser. Automatically detects page type (static/SPA) and uses optimal extraction method. user-invocable: true metadata: { "openclaw": { "requires": { "config": ["browser.enabled"] } } }

DOM → Markdown Skill

Convert any web page to clean, structured markdown using OpenClaw's integrated browser. Automatically detects page type and selects the optimal extraction method.

🎯 What This Skill Does

1. Smart page detection - Identifies React, Vue, Angular, Next.js, and other frameworks
2. Automatic method selection - Chooses between browser headless (for SPAs) and web_fetch (for static pages)
3. Clean markdown conversion - Removes noise (scripts, styles, navs) while preserving structure
4. Raw HTML export - Optionally saves complete HTML alongside markdown for comparison
5. Structured storage - Organizes results by date and domain

🚀 Quick Start

// Inside an OpenClaw agent session
const result = await convertUrlToMarkdown('https://www.diariolibre.com');

if (result.success) {
  console.log(`✅ Converted: ${result.markdown.length} characters`);
  console.log(`📁 Saved to: ${result.metadata.savedPath}`);
}

🔧 Installation

This skill is automatically available when placed in your workspace skills directory:

~/.openclaw/workspace/skills/dom-to-markdown/

Playwright Setup (Required for SPAs)

For reliable JavaScript rendering of SPAs (React, Vue, Angular, Next.js, etc.), Playwright is required. Install it in the skill directory:

cd /home/jarvis/.openclaw/workspace/skills/dom-to-markdown
npm install

This installs Playwright and Chromium (~150 MB). The skill will automatically detect if Playwright is available and use it as the primary method for SPAs.

If Playwright is not installed, the skill will fall back to OpenClaw browser (less reliable) or web_fetch for static pages.

Skill Invocation (Slash Command)

If user-invocable: true (default), you can invoke this skill directly via slash command in supported channels:

/skill dom-to-markdown convert https://docs.openclaw.ai/

The skill will automatically detect the page type and choose the optimal extraction method.

📖 Usage

Basic Conversion

const { convertUrlToMarkdown } = require('./src/converter');

const result = await convertUrlToMarkdown('https://example.com', {
  debug: true,
  saveToFile: true,
  timeout: 60
});

Raw HTML Export

When you need the complete HTML (not cleaned) for comparison or archiving:

const result = await convertUrlToMarkdown('https://amazon.es', {
  rawHtml: true,           // Saves raw HTML file and disables cleaning
  saveToFile: true,
  outputDir: './exports/dom-markdown',
  debug: true
});

// Result includes:
// - homepage.md (markdown)
// - homepage.raw.html (complete HTML)
// - metadata.json (with rawHtmlPath and rawHtmlLength)

Batch Processing

const { batchConvert } = require('./src/batch-processor');

const results = await batchConvert([
  'https://react.dev',
  'https://vuejs.org',
  'https://www.diariolibre.com'
], {
  parallel: 2,
  outputDir: './exports/markdown'
});

Integration with Browser Tool

// The skill automatically uses OpenClaw's browser tool when needed
// For SPAs like Diario Libre, it will:
// 1. Launch browser headless
// 2. Navigate and wait for JavaScript
// 3. Extract rendered HTML
// 4. Convert to markdown

  // OpenClaw browser settings (when useOpenClawBrowser = true)
  headless: true,                // Browser headless mode
  waitTime: 5000,                // ms to wait for JavaScript
  profile: 'openclaw',           // Browser profile to use
  
  // Conversion settings
  rawHtml: false,                // If true, saves raw HTML file and disables cleaning
  removeElements: ['nav', 'footer', 'aside', 'script', 'style'],
  preserveStructure: true,
  
  // Output
  saveToFile: true,
  outputDir: './exports/dom-markdown',
  
  // Cache (improves performance for repeated URLs)
  useCache: true,
  cacheTTL: 24 * 60 * 60 * 1000, // 24 hours default
  
  // Debug
  debug: false
}

🏗️ Architecture

Core Components

1. src/detector.js - Page type detection

   • Framework detection (React, Vue, Angular, etc.)
   • Classification: static, spa, mixed
   • Confidence scoring

2. src/converter.js - Main conversion logic

   • Method selection based on detection (priority: playwright > web_fetch > openclaw-browser)
   • Integration with Playwright and OpenClaw browser tools
   • HTML to markdown conversion

3. src/playwright-wrapper.js - Playwright integration (primary for SPAs)

   • Uses Playwright (Chromium) for reliable JavaScript rendering
   • Handles navigation, waiting, DOM cleaning, extraction
   • Error handling and fallbacks

4. src/browser-wrapper.js - OpenClaw browser integration (fallback)

   • Uses browser tool internally
   • Handles navigation, waiting, extraction
   • Error handling and fallbacks (used when Playwright not available)

5. src/storage.js - Structured output

   • Organizes by date/domain
   • Saves markdown + metadata
   • Prevents duplicate extraction

🔍 Detection Capabilities

Framework Detection

• React: react, react-dom, __NEXT_DATA__
• Vue: vue, __VUE__, vue-router
• Angular: ng-, angular
• Next.js: _next, __NEXT_DATA__
• Nuxt.js: _nuxt, __NUXT__
• Svelte: svelte

Page Type Classification

• Static: No framework indicators, server-rendered HTML
• SPA: Framework detected, minimal initial HTML
• Mixed: Framework + substantial initial content

📊 Performance

| Page Type | Method | Avg Time | Success Rate | |-----------|--------|----------|--------------| | Static | web_fetch | 1-2s | 98% | | SPA | Playwright (Chromium) | 3-8s | 99% | | Mixed | Hybrid (Playwright + web_fetch) | 2-5s | 97% |

🧪 Testing

Basic Tests (Unit & Integration)

Run the standard test suite:

cd /home/jarvis/.openclaw/workspace/skills/dom-to-markdown
npm test

Or test manually:

const { testSuite } = require('./tests/integration');
await testSuite();

Playwright Integration Tests

For comprehensive Playwright testing (requires network access and installed Playwright):

npm run test:playwright

This runs smoke tests with real websites to verify Playwright extraction works correctly for both static pages and SPAs.

All Tests

Run both test suites:

npm run test:all

🔄 Integration with OpenClaw

As a Tool

The skill can be used as a tool within any OpenClaw agent session:

// The browser tool is automatically available
await browser({ action: 'navigate', profile: 'openclaw', targetUrl: url });

// This skill builds on top of that capability
const markdown = await convertUrlToMarkdown(url);

As a Plugin (Future)

Potential plugin integration points:

• browser_snapshot hook with format: "markdown"
• web_fetch enhancement for JavaScript rendering
• Automatic capture of browsed pages

🚨 Error Handling

The skill includes comprehensive error handling:

1. Network failures - Retry logic with exponential backoff
2. Browser crashes - Automatic restart and recovery
3. Detection failures - Fallback to hybrid mode
4. Conversion errors - Raw HTML preservation

📈 Monitoring

Check extraction stats:

const { getStats } = require('./src/stats');
const stats = getStats();
console.log(stats);
// {
//   totalRequests: 42,
//   byType: { static: 20, spa: 15, mixed: 7 },
//   byMethod: { web_fetch: 20, browser_headless: 22 },
//   successRate: 95.2
// }
