Swarup-Ingale/sigma ? reverse-engineered prompt

I want a GitHub repository for Sigma detection rules, like a shared library of security searches that people can use across different SIEM tools.

Please set it up so the repo has clear sections for general detections, threat hunting, emerging threats, compliance, placeholder rules, and any older or unsupported rules that shouldn’t be mixed in with the main content. It should feel organized and easy for someone in security to browse, add new rules, and keep quality high.

Make sure the rules can be checked automatically so bad or broken rules are caught early, and add a simple testing setup for regression checks. Include the usual contributor guidance, release info, and a clean README that explains what Sigma is, why it’s useful, and how to get started writing or using rules.

Keep it practical and community friendly, with a structure that would work for a large open source detection project. If you need to look up the current Sigma rule format or best practices online, go ahead and do that.
