Hey, right now there isn’t a separate toggle in Settings to fully disable the built-in subagents. But there’s a working workaround. Add a User Rule:
Cursor Settings > General > Rules for AI - add:
Never use subagents. Do not launch any sub-agents for any task.
This is what @jes and @99power suggested above, and it works. More about rules: https://cursor.com/docs/rules
I wouldn’t recommend rolling back to an older version. Old versions don’t get updates and may stop working correctly with the API.
Also, for cost control, the built-in subagents (Explore, Browser, Bash) use a fast, cheap model, so the cost is minimal. If you want subagents to use the same model as the main agent, you can enable Max Mode in chat settings.
Let me know if subagents still launch after you add the rule.
