this should work: https://github.com/borkdude/clj-kondo/blob/master/doc/editor-integration.md#spacemacs (except for the edn linter, which will be added in the next version). thanks @rahul080327

I've created an issue to consider adding Joker and clj-kondo to the Spacemacs Clojure layer, along with Eastwood which is already there. Then make the linters optional to the Clojure layer, so people have choice in which ones they use (and because there is an external install for Jocker and clj-kondo) https://github.com/syl20bnr/spacemacs/issues/12453
