Pass messages between 2 Cursor Instances/ Repos (frontend and backend

My app frontend and backend are 2 separate codebases, and I use cursor with each at the same time. When working on features that involve both I often type something like:

“give me a brief summary of this so i can copy paste and ask our backend AI coder”

Would be cool if I could type something like “update the ai in our backend about this” and have it send a summary directly to it. Basically a simple hotline between different cursor instances. Then I could even give each one a name in system instructions and be like “ok go update todd on this” etc.

Also to cursor team: you guys have done an incredible job and I’m loving it!

Hello @mlapeter

I think you can do this by adding both repos to the same workspace. Follow these steps and let me know if it worked for you!

  • Open your frontend in cursor
  • Go to File → Add Folder to Workspace and add your backend

You should be able to reference files and do agentic edits in both repos

Thanks, I’ll check that out! My current workflow is asking question in backend, then while agent is working on it, i ask question in frontend, and switch back and forth so i’m never really waiting for the agent to finish. I’ll give your idea a try and see how it works!
