rubikproxy/rubikrecon ? reverse-engineered prompt

Build me a simple command line security recon tool in Bash that I can run against a domain or IP and get a clean HTML report at the end.

I want it to automate the usual bug bounty recon steps for me, like finding subdomains, checking DNS details, pulling WHOIS and IP info, testing for open ports and services, looking at HTTP security headers, checking robots.txt, identifying the tech stack, and doing a basic firewall check. It should gather everything into one readable report with a summary and clear sections for each result.

Make it easy to use from one script, something like giving it a target and an output file name. If it needs common external tools, wire them together and handle missing dependencies gracefully. Keep the output organized and beginner friendly, since I want to be able to run it quickly during reconnaissance and share the report with others.
