prakashru/nuclei ? reverse-engineered prompt

Build me a fast command line vulnerability scanner like Nuclei.

It should let me scan a single URL, a list of hosts, or network targets, then run checks from simple YAML templates so I can customize detections without coding everything from scratch. I want it to support common web and network checks, like HTTP, DNS, TCP, SSL, and similar protocols, and to be able to chain a few steps together so the scan is more accurate and avoids obvious false positives. Make it easy to plug in my own templates, run lots of targets quickly, and use it in CI for basic security checks and regression testing.

Please include a clean help command, sensible defaults, clear output, and a way to save results in a format that’s easy to use later. If you need current details for template syntax or scan options, look up the docs online first.
