j3ssie/metabigor ? reverse-engineered prompt

Build me a Go command line tool for OSINT and recon that helps map a target’s infrastructure without needing API keys.

I want it to take things like an ASN, IP, domain, or company name, then pull back useful info such as network ranges, certificate transparency subdomains, open ports and CVEs, related domains, CDN or WAF hints, IP clustering, public code search results, and archived URLs. It should be easy to pipe commands together, accept input from arguments, stdin, or a file, and support clean output for terminal use, flat piping, JSON, and CSV.

Make it feel practical for bug bounty and security work, with commands like net, cert, ip, github, cluster, related, and url. If a source needs extra setup, prefer free sources or offline data where possible, and keep results deduplicated and easy to combine. Please look up current docs online if you need to.
