Months ago I wrote a script for myself to keep track of my training data. It helped me update my files as they got bigger by checking if I forgot to add or remove objects from intents, actions, slots etc. Feel free to use and make comments

Awesome @Krogsager! Thanks a lot for sharing! 
@Krogsager don’t you get warnings from rasa_core for that when training?
The only warning I get when running python -m rasa_nlu.train
2018-10-25 12:27:15 WARNING rasa_core.training.dsl - Found unknown intent ‘int_freetext’ on line 326. Please, make sure that all intents are listed in your domain yaml.
Which I think is insufficient.
I get nothing when running python -m rasa_core.train.
You mean the other way around right? 
but fair enough. There’s also warnings/errors for actions not existing
Oh yeah, something looks wrong in that post
