When faced with more than a dozen intents that might overlap in purpose, depending in interpretation, it is difficult to test.

I create a chat with a problem and a bot answers: by which intent?

I could be trouble shooting a new intent but under the covers, an overlapping pre-existing intent could be the one triggered.

"Overlapping" you say...

Yes. Some intents are subsets, supersets or over lapping.

E.G.

1) I have an outlook web question

2) how do I use outlook on my iphone

3) I need to install outlook
