- Command argument constraints allow you to apply additional filters per-argument with the same type
- You can specify your own constraint rules for your own argument types, but existing ones have been put in place for int, float, long, and double to specify min and max values
- Example is int<1,100>:num to limit from 1 to 100, or <,100> for up to 100, or <100,> for 100 or above
