How hard is it to build something like this on Farcaster? We already have AI agents, but is it difficult to integrate real-time data (casts)?

This is build into the first party UI, which isn't possible on Warpcast but would be possible with other clients. Seems pretty straight forward tbh. Not as cool but could easily be done as a bot on WC today.
