Anyone figured out a robust mechanism for predicting some thing will be a long running task (that would require push notification)?

I am trying to figure out an approach for push notifications.

How can we predict when what is an arbitrary, natural language request will trigger a long-running task rather than a quick response?

Example Scenarios:

A simple request like "What is the population of New York City?" could be answered quickly through a lookup. This can occur on the same open connection , standard request / response.

A more complex request like "What is the historical trend of global carbon emissions in New York over the past 100 years, broken down by Bronx, Brooklyn, Manhattan, Queens, and Staten Island, while factoring in economic growth rates and average weather conditions?" - well this would require a much longer process to compute, pulling data from multiple sources and potentially performing advanced analysis. Likely more then one agent.
