Constant freezing when agent tries to run commands

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

On agent mode, when it tries to run commands it frequently gets stuck or frozen. I saw other topics about this but they were either solved or not exactly what I’m seeing.
Even just echo is stuck, as you can see in the screenshot. I waited for over 5 minutes.

Steps to Reproduce

Put the AI in agent mode, on Auto, and ask for it to run a command. Frequently, it will get stuck. Sometimes stopping it and asking for it to retry works, but it’s infrequent.

Expected Behavior

Should be able to run allowed commands.

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the report. This looks like a known shell integration issue in 2.3.x - the agent can’t run commands properly in the terminal.

Try Legacy Terminal as a workaround:

  • Settings > Cursor Settings > Agents > Legacy Terminal - turn it on
  • Restart Cursor
  • Try running the command through the agent again

If that doesn’t work, I’ll need a bit more info:

  • Request ID from the frozen chat (chat menu > Copy Request ID)
  • Console logs: Cmd + Shift + P > Developer: Toggle Developer Tools > Console tab (screenshot or error text)
  • What shell you’re using (echo $SHELL in terminal)

Similar cases got fixed with this workaround - let me know how it goes: Cursor commands hang indefinitely (no terminal attached) on Fish shell

Great, I made the change and reloaded the window and it seems to have worked! Thank you
