Updated https://practical.li/spacemacs/debug-clojure/sayid-debug/ page to clarify alias definitions require the sayid middleware in :main-opts to run correctly. So the preferred workflow is to use cider-connect Added a note that using jack-in is a little problematic (although technically achievable - I can document how to configure jack-in to run sayid using a .dir-locals.el config if it is of value - let me know)
