Hey, thanks for the report.
This is a known issue and other users have reported the same thing:
- Task Tool Missing for Custom Agents in .cursor/agents/ + Documentation Pages Return Errors
- `Task` tool not found
The team is aware and is looking into it. The issue is that even when subagent_delegation_context is injected into the prompt, the Task tool itself isn’t bound to the agent. There’s no timeline yet, but your report helps raise the priority.
About Max Mode, no, it’s not related. Subagents should work on the usage-based plan without Max Mode.
Can you share the Request ID with Privacy Mode turned off? That’ll help the team dig deeper:
- Cursor Settings (
Ctrl+Shift+J/Cmd+Shift+J) - Find “Privacy Mode” and turn it off temporarily
- Try to reproduce the issue in a new chat
- In the chat, click the three dots (top right) > Copy Request ID
- Send it here
After that, you can turn Privacy Mode back on right away.
