Preferences (EXTEND.md)
Use Bash to check EXTEND.md existence (priority order):
# Check project-level first
test -f .canghe-skills/canghe-url-to-markdown/EXTEND.md && echo "project"
# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.canghe-skills/canghe-url-to-markdown/EXTEND.md" && echo "user"┌────────────────────────────────────────────────────────┬───────────────────┐ │ Path │ Location │ ├────────────────────────────────────────────────────────┼───────────────────┤ │ .canghe-skills/canghe-url-to-markdown/EXTEND.md │ Project directory │ ├────────────────────────────────────────────────────────┼───────────────────┤ │ $HOME/.canghe-skills/canghe-url-to-markdown/EXTEND.md │ User home │ └────────────────────────────────────────────────────────┴───────────────────┘

EXTEND.md Supports: Default output directory | Default capture mode | Timeout settings
Features
- Chrome CDP for full JavaScript rendering
- Two capture modes: auto or wait-for-user
- Clean markdown output with metadata
- Handles login-required pages via wait mode
Usage
# Auto mode (default) - capture when page loads
npx -y bun ${SKILL_DIR}/scripts/main.ts <url>
# Wait mode - wait for user signal before capture
npx -y bun ${SKILL_DIR}/scripts/main.ts <url> --wait
# Save to specific file
npx -y bun ${SKILL_DIR}/scripts/main.ts <url> -o output.mdOptions
| Option | Description |
|---|---|
<url> | URL to fetch |
-o <path> | Output file path (default: auto-generated) |
--wait | Wait for user signal before capturing |
--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<slug>: From page title or URL path (kebab-case, 2-6 words)- 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.
Extension Support
Custom configurations via EXTEND.md. See Preferences section for paths and supported options.
