No back button when I open a subagent's window

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

If I open a subagent’s conversation, I cannot go back to my original conversation.

Steps to Reproduce

Repro:

  1. I create a conversation/session.
  2. My conversation creates a subagent, and then the subagent creates a report,
  3. I open the subagent’s report → this now replaces my main conversation’s tab.
  4. I no longer have any buttons to navigate back to the main conversation.

Expected Behavior

There should be a back button to go back to the original conversation

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hi @sk_monkeytyper, Thanks for the post! We actually just merged a fix for this that will be live in 3.13. Please update your Cursor app later this week to 3.13 and let us know if you still see this issue once you’re on 3.13.

Still reproducing on 3.15.19 (after the 3.13 Back-button merge).

@kevinn you asked us to update if this was still broken after 3.13. It is.

Where does the bug appear (feature/product)?

Cursor IDE — Multitask Mode / nested subagent view

Describe the Bug

In Multitask Mode, clicking a nested subagent (example: a coding-PR subagent) replaces the main Agent/Chat panel with the subagent transcript. There is no Back button, breadcrumb, or similar in-pane control. The parent Multitask session input box disappears. File tabs at the top are editor tabs, not a way back to the parent chat. Sidebar click and ⌘[ do not return to the parent.

Staff previously said a Back button was merged for 3.13. I am on 3.15.19 and still get replace-with-no-back. Related: “Back” button within a sub-chat and Agent reply box disappears after response — stuck in read-only subagent view? panel — on that later thread, staff said a top-bar back arrow should work on 3.13.10. I do not have a usable Back control in this Multitask subagent pane.

Steps to Reproduce

  1. Start a Multitask Mode parent Agent session (/multitask or equivalent).
  2. Let the parent spawn a nested subagent for a coding PR.
  3. Click the nested subagent entry / report in the parent pane.
  4. The Agent/Chat panel is replaced by the subagent transcript. Parent input is gone.
  5. Try to return: no Back button or breadcrumb in the pane; editor tabs at the top are not the parent chat; sidebar click does not restore the parent; � no Back button or breadcrumb in the pane; editor tabs at the top are not the parent chat; sidebar click does not restore the parent; ⌘[ does not restore the parent.

Expected Behavior

A Back control (or equivalent) returns to the parent Multitask chat without New Chat + History workarounds.

Actual Behavior

Stuck in the subagent-only pane with no in-pane escape. Parent input is gone. The only reliable workaround is Show Chat History and reopen the parent thread. That works, but the replacement UI has no in-pane escape.

Screenshots

Attached: subagent-only pane with no Back control. Top tabs are editor/file tabs, not chat navigation.

Does this stop you from using Cursor

No — Cursor works, but this is annoying. History reopen is the only way back.
