Website Scraper Pro

Run a local script to scrape a single web page into clean markdown or deterministic JSON with Crawl4AI. Use when: user needs direct page retrieval from a URL...

Skill: Website Scraper Pro

When to use

• The user wants the content of a single web page from a specific URL.
• The user wants clean markdown extracted from an article, docs page, blog post, or landing page.
• The user wants a JS-aware scrape for a page that depends on client-side rendering.
• The user wants deterministic query-focused narrowing of one page without using an AI model inside the skill.
• The user wants structured JSON output with markdown, title, links, and metadata.

When NOT to use

• The user wants a broad web search across multiple sources.
• The user wants a site-wide crawl, recursive crawl, or multi-page extraction workflow.
• The user wants AI summarization, synthesis, or answer generation inside the scraper itself.
• The user wants authenticated browser automation or interactive form submission.

Commands

Scrape a page to markdown

uv run /root/.openclaw/workspace/skills/website-scraper-pro/src/main.py <URL>

Scrape a JS-heavy page

uv run /root/.openclaw/workspace/skills/website-scraper-pro/src/main.py <URL> --js

Scrape a page and narrow by query

uv run /root/.openclaw/workspace/skills/website-scraper-pro/src/main.py <URL> --query "<TEXT>"

Return deterministic JSON

uv run /root/.openclaw/workspace/skills/website-scraper-pro/src/main.py <URL> --format json

Examples

# Default markdown scrape
uv run /root/.openclaw/workspace/skills/website-scraper-pro/src/main.py https://example.com

# JS-aware scrape
uv run /root/.openclaw/workspace/skills/website-scraper-pro/src/main.py https://example.com --js

# Query-focused retrieval
uv run /root/.openclaw/workspace/skills/website-scraper-pro/src/main.py https://example.com --query "documentation examples"

# JSON output
uv run /root/.openclaw/workspace/skills/website-scraper-pro/src/main.py https://example.com --format json

Output

• Default output is clean markdown for a single page.
• --query keeps the output deterministic and non-LLM.
• --format json returns deterministic JSON with fields such as title, url, markdown, links, and metadata when available.

Notes

• This v1 does not use AI models internally. It is a deterministic retrieval tool only.
• The skill is single-page only. It does not do deep crawling, site maps, schema extraction, or RAG.
• uv run reads the inline # /// script dependency block in main.py and installs crawl4ai in an isolated environment.
• If browser setup is missing, run one-time setup commands such as:
  • uv run --with crawl4ai crawl4ai-setup
  • uv run --with crawl4ai python -m playwright install chromium
• Do NOT use web search for this workflow when a direct URL is available.
• Call uv run src/main.py directly as shown above.
