|--------|---------|
| `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**: 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

```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
```

## 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) |

## 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`

## 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.
