We have a few backend services written in Clojure. We expose nrepl ports in our testing SDE k8s clusters. Our UI is all in Typescript, but I use nbb with Playwright - that gives me another REPL. LLM can poke through things in the UI REPL, while simultaneously running subagents that monitor situation in the cluster and then can dynamically change backend behavior. This all happens dynamically, without recompiling anything, without restarting, re-deploying, even saving the code (until it works), without losing the state.
