Skyfall is a Ruby library for connecting to the "firehose" of the Bluesky social network, i.e. a websocket which streams all new posts and everything else happening on the Bluesky network in real time. The code connects to the websocket endpoint, decodes the messages which are encoded in some binary formats, and returns the data as Ruby objects, which you can filter and save to some kind of database (e.g. in order to create a custom feed).
