URL to Markdown
Fetches any URL via Chrome CDP and converts HTML to clean markdown, with automatic image downloading.
Script Directory
Important: All scripts are located in the scripts/ subdirectory of this skill.
Agent Execution Instructions:
- Determine this SKILL.md file's directory path as
SKILL_DIR
- Script path =
${SKILL_DIR}/scripts/<script-name>.ts
- Replace all
${SKILL_DIR} in this document with the actual path
Script Reference:
| Script | Purpose |
|---|
scripts/main.ts | CLI entry point for URL fetching |
scripts/download-images.ts | Image download and path rewriting |
Preferences (EXTEND.md)
Use Bash to check EXTEND.md existence (priority order):
# Check project-level first
test -f .daftai-skills/daftAI-url-to-markdown/EXTEND.md && echo "project"
# Then user-level
test -f "$HOME/.daftai-skills/daftAI-url-to-markdown/EXTEND.md" && echo "user"
| Path | Location |
|---|
.daftai-skills/daftAI-url-to-markdown/EXTEND.md | Project directory |
$HOME/.daftai-skills/daftAI-url-to-markdown/EXTEND.md | User home |
| Result | Action |
|---|
| Found | Read, parse, apply settings |
| Not found | Use defaults |
EXTEND.md Supports: Default output directory | Default capture mode | Timeout settings | Image download toggle
Features
- Chrome CDP for full JavaScript rendering
- Two capture modes: auto or wait-for-user
- Automatic image downloading with local path rewriting
<picture> / <source> tag support for complete image extraction
- Clean markdown output with metadata
- Handles login-required pages via wait mode
Usage
# Auto mode (default) - capture and download images
bun ${SKILL_DIR}/scripts/main.ts <url>
# Wait mode - wait for user signal before capture
bun ${SKILL_DIR}/scripts/main.ts <url> --wait
# Skip image downloading
bun ${SKILL_DIR}/scripts/main.ts <url> --no-images
# Save to specific file
bun ${SKILL_DIR}/scripts/main.ts <url> -o output.md
Options
| Option | Description |
|---|
<url> | URL to fetch |
-o <path> | Output file path (default: auto-generated) |
--wait | Wait for user signal before capturing |
--no-images | Skip downloading images (keep remote URLs) |
--timeout <ms> | Page load timeout (default: 30000) |
Capture Modes
| Mode | Behavior | Use When |
|---|
| Auto (default) | Capture on network idle | Public pages, static content |
Wait (--wait) | User signals when ready | Login-required, lazy loading, paywalls |
Wait mode workflow:
- Run with
--wait → script outputs "Press Enter when ready"
- Ask user to confirm page is ready
- Send newline to stdin to trigger capture
Output Format
YAML front matter with url, title, description, author, published, captured_at fields, followed by converted markdown content.
Output Directory
url-to-markdown/<domain>/
├── <slug>.md
└── images/
├── image1.png
├── image2.svg
└── ...
<slug>: From page title or URL path (kebab-case, 2-6 words)
- Images are saved to
images/ subdirectory next to the markdown file
- Image references in markdown use relative paths:
images/<filename>
- Conflict resolution: Append timestamp
<slug>-YYYYMMDD-HHMMSS.md
Environment Variables
| Variable | Description |
|---|
URL_CHROME_PATH | Custom Chrome executable path |
URL_DATA_DIR | Custom data directory |
URL_CHROME_PROFILE_DIR | Custom Chrome profile directory |
Troubleshooting: Chrome not found → set URL_CHROME_PATH. Timeout → increase --timeout. Complex pages → try --wait mode.
Post-Capture Validation
After the script finishes, the agent MUST perform the following validation steps before reporting completion:
1. Completeness Check
- Use
read_web_page to fetch the original URL
- Compare the generated Markdown against the original page content
- Ensure no paragraphs, sections, or headings are missing
2. Video & Embedded Media Detection
- Search the original page source (
curl) for <video>, <iframe>, <source>, or links to Vimeo, YouTube, Wistia, Lottie, etc.
- For each embedded video found, insert a link at the correct position in the Markdown:
[视频:<caption or description>](<video_url>)
- Videos are often hidden in JS-rendered
mediaGallery blocks — check the page's raw HTML/JSON for vimeo.com, youtube.com, .mp4, .webm
3. Image Placement Verification
- Confirm that images appear after the correct paragraphs, matching their positions on the original page
- Check that all
 references point to files that actually exist in the images/ directory
4. Irrelevant Content Cleanup
- Remove navigation menus, tag/category lists, newsletter signup forms, "Related articles" sections, footer boilerplate, and social media icons
- Remove duplicate titles (e.g., page title repeated as H1)
- Keep only the article body content and author attribution
5. Formatting & Style Verification
- Check that bold/italic emphasis is preserved (not stripped during conversion)
- Verify heading hierarchy (H2/H3 levels match the original page structure)
- Confirm ordered/unordered lists retain their structure
- Ensure blockquotes are properly converted with
>
- Verify code blocks use ``` fencing with correct language tags
- Check that
<hr> elements are converted to ---
- Note: colors, fonts, spacing and other CSS-only styles are out of scope for Markdown
6. Link Verification
- Fix broken links caused by inline cards or embedded previews spanning multiple lines
- Convert relative links (e.g.,
/blog/some-post/) to absolute URLs (e.g., https://domain.com/blog/some-post/)
- Ensure all
[text](url) links are properly formatted
