Hi to the community !
When cutting the steerer the last tiny bit cracked a bit, causing a splinter missing in the very outer layer of the carbon.
I just wanted to be sure that this shouldn't cause any trouble? I attached photos with my thumb next to it for scale.
Its also possible for me to cut another 5 mm, If this should be considered safer. Are there any tips to prevent this kind of cracking? Using (what kind of?) tape or something?

Thanks a lot for your help!
