s-r-e-e-r-a-j/WebExtractor ? reverse-engineered prompt

Build me a lightweight Python command line tool called WebExtractor that I can run on Linux and Termux.

I want it to take a website URL, scan the page, and pull out email addresses, phone numbers, and links from the site, including visible links, hidden links, and social media links. It should show the results in a clean, easy to read format, and give me the option to save everything to a folder for later review.

Make it simple to use from the terminal, with a straightforward prompt flow, and include an install script so it can set itself up on Linux or Termux. If it helps, add environment detection so the setup works smoothly in either place.

Please keep it fast and lightweight, and make sure it handles the output neatly. This is for authorized OSINT and ethical testing only, so I just want a practical tool that works well and is easy to run.
