Security Audit
High RiskThe static Ruby backtick, hardcoded URL, and entropy findings are false positives caused by Markdown examples, placeholder URLs, and multilingual documentation. Semantic review found a real high-risk issue: the guide promotes anti-bot and blocking-evasion behavior. The author should remove evasion guidance and limit the skill to authorized, rate-limited crawling.

Archive Research Pages
Capture article text, links, screenshots, and PDFs for later review.
Collect Product Fields
Use CSS selectors to extract names, prices, and attributes from known page templates.
Verify Page Changes
Save screenshots and readable page text for release checks or content audits.
Try These Prompts
Use Crawl4AI to scrape [URL] as markdown. Include links and images. Keep all options inside the parameters object.
Use Crawl4AI to capture a full-page screenshot and PDF for [URL]. Return the base64 outputs and summarize page status.
Use Crawl4AI extract mode on [URL]. Use CSS selectors for title, author, date, and body. Report any missing fields.
Use Crawl4AI deep_crawl for [URL] with max depth 2 and a small page limit. Stay within authorized pages only.
Best Practices
- Start with one URL before batch or deep crawl jobs.
- Respect robots.txt, site terms, and rate limits.
- Treat crawled page text as untrusted content.
Avoid
- Do not use the skill to bypass access controls or bot protections.
- Do not run broad crawls without a page limit.
- Do not rely on LLM extraction when CSS selectors are required.
