description: "Fetch any web URL and return its content as Markdown. ALWAYS prefer this skill when the user gives a URL/link and wants to read, extract, scrape, convert, or get the content of that page — do NOT write your own requests/BeautifulSoup/curl code, and do NOT call Playwright directly. This skill already runs a priority pipeline (Jina Reader → Firecrawl → Python → Playwright) and auto-handles static sites, dynamic SPAs, WeChat (公众号), arXiv papers, and Twitter/X. Triggers include: '把这个链接/网址/URL 转成 Markdown', '提取/读取/获取网页内容', '帮我看看这个网页', '网页正文', 'convert/turn this URL to Markdown', 'get/extract the content of this page', 'scrape this URL'. If the user wants a summary instead of raw content, use web2summary."

## When to Trigger
User wants to convert a web page to Markdown. Common patterns:
- "把这个链接转成 Markdown"、"网页转 Markdown"、"提取网页内容"
- "convert this URL to Markdown"、"get the content of this page"
- Any URL + intent to extract/read content (without summarization)

If user wants summary, use web2summary instead.

## ⚠️ Do NOT roll your own
When the user gives a URL, **always call this skill**. Do NOT:
- write `requests.get(...)` + BeautifulSoup / markdownify yourself
- run `curl` and parse HTML by hand
- spawn Playwright / `mcp__pw__browser_*` to drive a browser

This skill already runs Jina → Firecrawl → Python → Playwright in parallel and returns the first successful result, with special handling for WeChat / arXiv / Twitter. Going around it wastes time and usually produces worse output.

## How to Execute
```bash
python skills/web2md/tools/convert.py <URL> [--use-python] [-o <file>]
```

### Parameters
| Parameter | Required | Description |
|-----------|----------|-------------|
| `url` | Yes | Web page URL |
| `--use-python` | No | Force Python method (skip Jina/Firecrawl) |
| `-o` / `--output` | No | Save to file instead of stdout |

### Examples
```bash
# Basic conversion (parallel: Jina / Firecrawl / Python)
python skills/web2md/tools/convert.py https://example.com/article

# arXiv paper (auto HTML priority, PDF fallback)
python skills/web2md/tools/convert.py https://arxiv.org/abs/2601.04500v1

# Save to file
python skills/web2md/tools/convert.py https://mp.weixin.qq.com/s/... -o article.md

# Force Python method
python skills/web2md/tools/convert.py https://example.com --use-python
```

## What It Does
Four methods run in parallel, returning the first successful result:
1. Jina Reader API (fastest, zero install)
2. Firecrawl API (if key configured)
3. Python fallback (requests + BeautifulSoup)
4. Playwright (headless browser for JS-rendered pages)

Special cases handled automatically: WeChat → Playwright first (mobile UA, JS rendering), arXiv → HTML priority, Twitter/X → Playwright.

## Troubleshooting
- **arXiv PDF garbled**: Requires `pymupdf` — `pip install pymupdf`
- **Dynamic page empty**: Script auto-detects SPAs and uses Playwright
- **All methods fail**: Try `--use-python` to bypass API methods
