Your training of a team of agents is a product you developed while working for that company and would be owned by them. You could in theory train a new team of agents after leaving the company, but it could not be trained on anything that isn't in your brain. If you gave it anything, like the old company's live metrics, then you'd be stealing trade secrets. The key difference from you personally learning those skills is that an agent trained on company data turns personal knowledge into a portable, structured artifact, which crosses from "your skill" into something that looks a lot more like company property.

This is my personal conclusion as well. But think about where this leads. In the future, agents will do most of the coding and our job is to guide and train them. Most of our skills would be externalized somehow, living in the agents instead of in our heads. Which means once you leave a company, you may have effectively lost a lot of your hard earned skills and experiences.
