This skill is a web-scraping framework that runs `AsyncWebCrawler` to fetch and parse pages and includes CLI scripts such as `python scrape_single_page.py`. It documents making network requests to arbitrary URLs (e.g., `https://example.com/page-{page}.json`) and running commands that read/write local files (e.g., `file://{input_file}`, `page_{page_num}.json`).
