Agentic AI question

Hello community,

I am trying to build an agentic Ai prototype.

But I am at a loss on how to convert a workflow into a Tool. For instance, I don’t see where I can input the Description.

Currently I don’t have access to any KNIME hub instance. Is it at all possible without such instance?

Can you help me out or point me to some resources, specifically on how to create Tools?

thanks very much beforehand!
