Unable to delete Agents from Agents Panel. Agents reappear

[onerobot (Beep Boop)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

After 3.0 update I am no longer able to completely delete agents that are no longer used from the Agents Panel.
After deleting an Agent, it will reappear after I send a prompt to another agent and that agent starts working.
Subsequent deletion does not solve the issue.
Issue persists after complete Cursor Reinstall (full nuke of Cursor folders on macOS)

Steps to Reproduce

Delete Agent - Agent disappears.
Prompt another agent, wait for it to start working, deleted agent reappears

Expected Behavior

Delete Agent - Agent disappears - does not reappear again.

Operating System

MacOS

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the detailed report. This is a known issue, a few users reported the same thing today on 3.0.9. That version includes a fix for zombie draft chats, but it doesn’t cover every case.

One quick question. Were the agents that came back unfinished drafts where the prompt was never sent, or fully completed agents with history? This will help us understand the scope of the bug.

The team is aware of the issue. Your report helps with prioritization, especially since a full reinstall didn’t help.
