description: Fetch any URL and convert to markdown using Chrome CDP. Supports two modes - auto-capture on page load, or wait for user signal (for pages requiring login). Use when user wants to save a webpage as markdown.
---
# URL to Markdown
Fetches any URL via Chrome CDP and converts HTML to clean markdown.
## Script Directory
**Important**: All scripts are located in the `scripts/` subdirectory of this skill.
**Agent Execution Instructions**:
1. Determine this SKILL.md file's directory path as `SKILL_DIR`
2. Script path = `${SKILL_DIR}/scripts/<script-name>.ts`
3. Replace all `${SKILL_DIR}` in this document with the actual path
**Script Reference**:
| Script | Purpose |
|--------|---------|
| `scripts/main.ts` | CLI entry point for URL fetching |
## Preferences (EXTEND.md)
Use Bash to check EXTEND.md existence (priority order):
```bash
# Check project-level first
test -f .baoyu-skills/baoyu-url-to-markdown/EXTEND.md && echo "project"
# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.baoyu-skills/baoyu-url-to-markdown/EXTEND.md" && echo "user"
```

**EXTEND.md Supports**: Download media by default | Default output directory | Default capture mode | Timeout settings
### First-Time Setup (BLOCKING)
**CRITICAL**: When EXTEND.md is not found, you **MUST use `AskUserQuestion`** to ask the user for their preferences before creating EXTEND.md. **NEVER** create EXTEND.md with defaults without asking. This is a **BLOCKING** operation — do NOT proceed with any conversion until setup is complete.
Use `AskUserQuestion` with ALL questions in ONE call:
**Question 1** — header: "Media", question: "How to handle images and videos in pages?"
- "Ask each time (Recommended)" — After saving markdown, ask whether to download media
- "Always download" — Always download media to local imgs/ and videos/ directories
- "Never download" — Keep original remote URLs in markdown
**Question 2** — header: "Output", question: "Default output directory?"
- "url-to-markdown (Recommended)" — Save to ./url-to-markdown/{domain}/{slug}.md
- (User may choose "Other" to type a custom path)
**Question 3** — header: "Save", question: "Where to save preferences?"
- "User (Recommended)" — ~/.baoyu-skills/ (all projects)
- "Project" — .baoyu-skills/ (this project only)
After user answers, create EXTEND.md at the chosen location, confirm "Preferences saved to [path]", then continue.

### Supported Keys
| Key | Default | Values | Description |
|-----|---------|--------|-------------|
| `download_media` | `ask` | `ask` / `1` / `0` | `ask` = prompt each time, `1` = always download, `0` = never |
| `default_output_dir` | empty | path or empty | Default output directory (empty = `./url-to-markdown/`) |
**Value priority**:
1. CLI arguments (`--download-media`, `-o`)
2. EXTEND.md
3. Skill defaults
## 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
- Download images and videos to local directories
## Usage
```bash
# 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.md
# Download images and videos to local directories
npx -y bun ${SKILL_DIR}/scripts/main.ts <url> --download-media
```
## Options
| 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) |
| `--download-media` | Download image/video assets to local `imgs/` and `videos/`, and rewrite markdown links to local relative paths |
## 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**:
1. Run with `--wait` → script outputs "Press Enter when ready"
2. Ask user to confirm page is ready
3. 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`
When `--download-media` is enabled:
- Images are saved to `imgs/` next to the markdown file
- Videos are saved to `videos/` next to the markdown file
- Markdown media links are rewritten to local relative paths
## Media Download Workflow
Based on `download_media` setting in EXTEND.md:
| Setting | Behavior |
|---------|----------|
| `1` (always) | Run script with `--download-media` flag |
| `0` (never) | Run script without `--download-media` flag |
| `ask` (default) | Follow the ask-each-time flow below |
### Ask-Each-Time Flow
1. Run script **without** `--download-media` → markdown saved
2. Check saved markdown for remote media URLs (`https://` in image/video links)
3. **If no remote media found** → done, no prompt needed
4. **If remote media found** → use `AskUserQuestion`:
- header: "Media", question: "Download N images/videos to local files?"
- "Yes" — Download to local directories
- "No" — Keep remote URLs
5. If user confirms → run script **again** with `--download-media` (overwrites markdown with localized links)
## 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.
