Hey, thanks for the report. This is a known issue with the Agent’s new terminal implementation on Windows, especially when PowerShell commands contain special characters like pipes.

Please try the following solution:

  • Open Cursor Settings with Ctrl+Shift+J
  • Go to the Agents tab → Inline Editing & Terminal
  • Enable “Legacy Terminal Tool”
  • Press Ctrl+Shift+P → select “Terminal: Kill All Terminals”
  • Fully restart Cursor
  • Test your Agent commands again

This has resolved similar PowerShell terminal issues for other users on Windows. The engineering team is aware that the new terminal implementation has ongoing issues on Windows.

Let me know if this resolves the problem!
