What I ask before adopting a new tool

I'm watching tools that make everyday development simpler, though I'm trying to be slower about assuming a promising demo will do that for an entire project. Setup is only the beginning.

My questions are fairly dull: can the team debug it, how does it fail, and what happens when we need to leave? I still enjoy trying new things. A small experiment gives that curiosity somewhere to go without signing the whole team up.
