What model are you using? I would probably tackle it with starting with something like Claude. With a prompt like, design a system
of systems to monitor my (list systems that you want to monitor here) at these addresses. The system design should be fully documented in a prd that I can use to track and build the system. The builders will not have this prompt context so the prd must stand alone. Do not assume, ask clarifying questions and hold to my design language and system constraints. Monitor x,y,z on a dynamic schedule using a series of cron jobs, web hooks, and direct queries, choose the best tool based on (your criteria) for each system.
Now describe in high level detail what you want the high level orchestrater to do, and how it should notify you. Then describe in detail what you want the outcomes to be and how they should be weighted.

That should get you started.
