The likelihood of an angel stealing your idea is pretty low. If an angel really gets enamored with your idea, s/he most likely will try to persuade you to work with him. The possibility is very slim that an angel already has or can build a technical/business team quickly with expertise in same domain to execute on your idea. The red flag for such situations is typically when someone tries to string you along for a while and keep trying to get more and more details from you. Before you engage with any angel, make sure you know what you want from him/her, final outcome for such conversations, and how long do you want to engage with him before moving on.
