dwisiswant0/go-dork — reverse-engineered prompt

Build me a really fast Go command line tool for security research that can run dork searches against Google, Shodan, Bing, DuckDuckGo, Yahoo, and Ask. I want to be able to pass a query directly, or pipe in multiple queries from stdin, and have Google be the default engine if I do not choose one. It should support paging through multiple result pages, optional custom headers for cases like Shodan cookies or user agent changes, an optional proxy, and a silent mode that prints only the found URLs so I can pipe the results into other tools.

Please make the CLI feel simple and polished, with clear help output and sensible examples. It should stop paging when there are no more results instead of wasting time. If some engines are a little brittle because of parsing differences, that is fine, just keep the behavior practical and document any caveats. Look up current search result formats or docs online if you need to.
