Hi, when I write a detailed PRD that I then feed into to Cursor Plan agent to write the actual plan, I get it to create to do items and phases that can run in the context window I have available (after taking into account the MCP services I am using). The problem is I cannot find a way to tell the planning agent that I want each of the todo items that are create to open in a new agent chat window so that it has a reference to the master plan but each task gets the full available context window etc. I can do this manually but creating the plan and then clicking on each todo item in the plan and selecting to run it in a new chat window but no matter what I try I cannot find a way to to get Cursor to do this automatically so I can simply press the Build button on the plan agent and leave it running over night and the to do items get created sequentially or in parallel (depending on the information in the todo item and plan document) automatically.
Has anyone managed to achieve this or is this not possible yet. If not possible, is there any plans to add this as this would be amazing if you could do this as you could define your complex plan and to do items and then leave it run while you sleep knowing that you are not going to run into context window issues and summarising stuff.
I completely understand what you’re trying to achieve. Current situation (February 2026): What you describe (pressing “Build” and having all the tasks in the plan automatically run in separate agent windows without supervision) is not yet implemented in Cursor.
The closest you can get right now: Cursor 2.2 (since December 2025) added the “Send Tasks to New Agents” feature, which allows you to: Create your plan using Plan Mode (Shift + Tab) Manually select the tasks you want to run Send them to new agent windows individually But this requires manual intervention; it’s not the automated workflow you need to leave running overnight. In the meantime, consider these alternatives: Consider using the Cursor CLI with scripts that open multiple instances. Vote or comment on similar feature requests in the forum so the team can see the demand. This functionality is being actively requested by the community, so it will likely appear in future releases. I hope this clarifies things!
