What constraints do you suggest? If it's just changing "make as many paperclips as possible" to "make at least x number of paperclips" (putting a cap on the reward it gets), here's a good explanation of why that doesn't really work: https://www.youtube.com/watch?v=Ao4jwLwT36M
If you're suggesting limiting the types of actions it can take, then to do that to the point that a superintelligence can't find a way around it (maybe letting it choose between one of two options and then shutting it down and never using it again) would make it not very useful, so you'd be better off just not making it at all

No, that's not what I'm saying. Any goal is compatible with any level of intelligence, there is no reason why it wouldn't be possible to follow a simple goal in a complex way. Again here's a video about that: https://www.youtube.com/watch?v=hEUO6pjwFOo
