# Unlike every other episode's demo script, this one does NOT build a
# disposable `muse init` repo -- it requires the local MuseHub dev stack
# (docker compose, `musehub` + `musehub_worker` containers) already running,
# per ~/ecosystem/musehub/.museagent.md. Re-run any block independently;
# nothing here is destructive except the throwaway `mcp-episode16-demo` repo
# it creates on the LOCAL hub.
