End To End Web Scraping · kayforkind bundle
Runs an end-to-end pipeline for legal, ethical web data collection: legality gate, recon, extractor design, polite fetching, parsing, validation, deduplication, and persistence with full provenance. Use when the user wants to scrape, crawl, extract, or harvest a site; parse a site into structured data; get structured data from the web; run a sitemap crawl; do RSS collect work; perform HTML extract or table scrape tasks.

Never bypasses CAPTCHAs, logins, paywalls, or anti-bot systems; honors robots.txt, rate limits, and site ToS. Triggers: scrape, crawl, extract, harvest, parse site, structured data from web, sitemap crawl, RSS collect, HTML extract, table scrape.
