It would be wise to provide a command execution automation tool ‘Python, PowerShell’ so that the agent can execute the projects, do unit tests or even launch its own scripts so that all this can be done in a single request from the developer!
Not sure, but i think thats how it works now 
isnt it? For me it does.
Yes indeed there are options, but you have to be present to validate the orders one by one, except what you need is for it to be able to continue completely independently as soon as you have to leave!
