Thank you for the compliment. I have just implmented your settings.json recommendation and it seems to be working very well!
I had to move the instantiation of the Clarifai app object out of:
#self.clarifai_app = ClarifaiApp(api_key=self.settings["api_key"])
self.clarifai_app = ClarifaiApp(api_key=self.settings["api_key"])
As the skill does not has access to the local file system, until initialize is called.
I am working on making the spoken reponse to the image tags a bit more interesting and will update with these changes on github and hackster.io when completed.
I am looking forward to your writeup of the pianobar-skill, looks like there are a lot of intersting things going on in there to learn from!
Thanks again for the compliment, tip and project respect on hackster.io!
