Show HN: Trawl – LLM-powered web scraper that calls the AI once - runs pure Go

Every scraper I've written has the same failure mode: it works for three months, a site redesigns, and my CSS selectors silently return empty strings. The data is still right there on the page - a human can find it instantly - but the scraper is blind. Trawl fixes this by splitting the problem. You describe what you want: trawl " --fields "title, price, rating, in_stock" The LLM (Claude) looks at one sample item and derives a full extraction strategy - CSS selectors, attribute mappings, type coercion, fallback selectors. That strategy gets cached.
