# 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**:
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 |
| `scripts/download-images.ts` | Image download and path rewriting |

## Preferences (EXTEND.md)

Use Bash to check EXTEND.md existence (priority order):

```bash
# 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

```bash
# 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**:
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
└── 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 `![](images/...)` 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
