In this example, a GenAI agent (as a permissioned entityOS user) searches for conversation (set by UUID/GUID in the event.json) that it is a participant in, for posts that have a subject containing @genai or @heyocto. It then passes the message to the GenAI service (in this example OpenAI) and then saves the response as a comment to the original post.
Example uses OpenAI, but you can change to any service you wish.
You can also change to a Python app - using github.com/ibcom-lab/entityos-learn-python as your starting point.
