Crazy that a tool like this doesn't already exist. Interested to see how this tool matures and also if it will change the way they write tests and generate test artifacts.
Great question. The magic is in the dynamic nature of the breakpoint triggering. If you want to SSH into a CI machine you need to know ahead of time that you want to investigate that machine and pause execution while it's going.
With the debugger, you set conditional rules like - 'if this fails - then trigger debugger and hold machine' - instead of trying to catch lightning in a bottle - it waits for you.
