Question: I'm looking for a solution that allows me to create complex bots with multiple skills and inter-skills interactions.

If you want a way to build more sophisticated bots with multiple skills and interactions among them, Maxbot is a good choice. This open-source library and framework offers unified messaging across multiple platforms and can incorporate other libraries and NLU services.
