Am I using DeepSeek correctly for vibecoding?

I installed the desktop harness, input my api key and pointed the workspace to a project. I've been vibe coding the same way I would have done with Claude or Codex, am I doing it right? I haven't got any specific use-cases or needs, I just want to be sure that I'm using it correctly because it has been spitting out the term "sandbox" left & right and it has be concerned that I'm not on the real thing 🤣
