Cursor-agent always ends execution abruptly when queuing new message

Where does the bug appear (feature/product)?

Cursor CLI

Describe the Bug

Whenever I queue a message on the cursor-agent while still executing the previous prompt, if I send the next prompt while it’s doing it, it always ends the execution and crashes. Then, when I type any other message on that input area, it just ignores it and I have to kill the cursor-agent and restart it again.

Steps to Reproduce

Open Cursor-Agent. Type any prompt, and while it’s processing that prompt, if you queue a second prompt, the Cursor-Agent will always crash. I’m running this Cursor-Agent in Debian servers, Ubuntu servers, and Mac OS machines, and I always get the same issue.

Expected Behavior

Allowing to queue prompts and process them once the previous is completed.

Operating System

MacOS
Linux

Current Cursor Version (Menu → About Cursor → Copy)

cursor-agent -v
2025.11.25-d5b3271

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report.

Currently, cursor-agent in interactive mode processes requests sequentially - sending a new request while the previous one is still running isn’t supported. The CLI expects you to wait for the current request to finish before sending the next one.

That said, the crash and the subsequent unresponsive input is definitely a bug. Even without queuing, it should handle this gracefully instead of crashing.

I’ll pass this to the team to improve error handling. For now, please wait for each request to complete before sending the next one.

If you need parallel work, use non‑interactive mode -p with multiple processes.

thank you Dean, for the moment I will use the -p
