Sub-agents in Cursor haven’t been functioning properly for me since their release, even when I explicitly specified their use in my prompts.
Today, I tried Opus 4.6, and I was pleasantly surprised to see that it delegated tasks to parallel sub-agents.
Finally! Sub-agents are working as intended in Cursor!
Just tried it, Cursor still says it can’t see the “Task” tool (version 2.4.28)
What if you explicitly list the available sub-agents in your AGENTS.md file and tell Cursor to use them in AGENTS.ts? I created my sub-agents in the .cursor/agents folder myself based on the official docs and they work now with Opus 4.6.
I’ve never seen them work previously with any other model.
