Great points, always believed and followed these. If I may add few, I will add the following.
I will be honest at all times. Even if you may not like what I say or do, I will still do whatever it takes to improve my coachee / team.
I will not show off my knowledge. I may at times be silent even if I know the solution, if that is required for my team to improve.
There are more, but these two are important in my view.
