Agent selection

One of the biggest challenges I had in playing around in next is not being able to see the data sources and understand the "art of the possible" with what agents can do today that I can put together in a swarm Some of the agents seem self-explanatory like email or telegram, but a lot of the more interesting data agents it's hard to know what data are available or what they can do, for example the new agent for the one I recommended, Financial Datasets, I can't really figure out what it offers. So for me to build swarms, I have some ideas but don't really know how to put them together
