Thanks for this! I've made a few modifications.

1. If the context is minikube, ensure the minikube vm is up.
2. use the unicode helm symbol (⎈) instead of "K:"
3. used a more neutral blue color instead of magenta

    if [[ $kubectl_context == "minikube" ]]; then
      local minikube_status=$(minikube status --format={{.MinikubeStatus}})
      if [[ $minikube_status != "Running" ]] then
        return
      fi

    prompt_segment 111 black "\u2388  $kubectl_context"
  fi
}

@ultimateboy where does this go in the zsh theme to apply it?
