Hey, thanks for the report. This is a known issue. We’ve seen it from several users.
The most common cause is the agent silently using a working directory that no longer exists, for example if the project folder was moved or renamed. When that happens, it can fail with empty output, 0 ms, exit 0, and no error message. Two other users with the exact same symptoms traced it to this:
- Agent cannot run any CLI commands
- Agent terminal: no stdout in tool result and read_file can't see files that terminal created
A few things to check:
-
Did you recently move, rename, or delete the project folder? If yes, fully close Cursor, then reopen it from the current folder location (File > Open Folder).
-
Open Developer Tools (Help > Toggle Developer Tools) and run
echo testvia the agent. Check the Console tab for errors, especially anything about a path beingundefinedor a directory not found. -
Open a completely new folder, even a temp one, in a fresh Cursor window and test if the agent terminal works there.
If a stale directory isn’t the cause, please share the DevTools Console output after running a command through the agent. That’ll help narrow it down.
