Of course not. Getting all of this done requires overwhelming amounts of surprise. Trump signing a flood of executive orders is a part of this: it takes time to figure out what's going on with each one, and how to combat it. And in that time, the damage can already be done.

Musk and his coup team aren't really accountable to anyone but Trump, and have no direct legal authority. The way that they get things done is by threatening and steamrolling people, and gaining control of important functions (like the ability to put people on leave or fire them). All of this requires some amount of secrecy and chaos in order to pull off. If they were posting detailed plans on their website, it would make those plans harder to execute.
