Unfortunately there is not a way to force Lex to ignore intent utterances, but Lex is smart enough to attempt to recognize at the slot level before checking the intent level.
I also have some similar situations where a slot elicit is also an intent utterance, but I've found that if the slotType values include those possible intent utterances, then Lex does a good job of checking and filling the slot before checking for a match in intents.
So with that in mind, here are a few options I would consider:
A.
Auto-fill the beginning of the description based on the previous IntentName or the phrase that triggered the intent. Then ask if they want to add to it in the elicit of description. That way, they would not need to repeat the phrases that trigger the intent. I would write the elicit prompt something like this:
In the description of this ticket I have already written "Resetting password." What else would you like to add to the description?
Even asking them to finish the sentence might work well:
Please complete this sentence to be added as the description of this ticket, "I am resetting my password because..."
B.
Add all of the intent utterances as one of the description's slotType values. This way, Lex will recognize the words used in the description as filling the slot before checking if they match an intent utterance.
C.
I would consider limiting the description, or even building the description from multiple slots. For example, maybe each description should include (1) reason, (2) priority/importance level, etc. And so build a slot for "reason" and "priority" and elicit those specifically with:
What is your reason for resetting your password?
What level of priority do you give this ticket?
Then in Lambda put those (and any others) together into a description.
