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](https://forum.cursor.com/t/cursor-commands-hang-indefinitely-no-terminal-attached-on-fish-shell/149176)
