Skill not working, probably the intent?

So first of all: This is my first try in skill development.
I am unsure what’s wrong… the only thing I try is to let the skill tell me a random number. But it isn’t even finding my skill? Could someone look into this and tell me why:
I’m not sure if the intent and dialog are correct.

Check the logs (/var/log/mycroft/skills.log) and see why it’s not loading?

I’m not sure if it’s the issue but you didn’t register you entity file.

Its still not working… I updated and now the entitys are registerd… I think.
Do you have other ideas why its not working?
