Cloud agent: “Start Multitasking” button does not appear when follow-ups are queued

Where does the bug appear (feature/product)?

Cloud Agent (GitHub, Slack, Web, Linear)

Describe the Bug

On a running Cloud Agent, “Start Multitasking” never appears.
I have 1 task Working and 2 follow-ups Queued. Locally, that state shows a Start Multitasking control so queued work can run in parallel. On this cloud agent the Working/Queued headers only show Stop All. There is no Start Multitasking button.
Related: staff said on /multitask doesn't work in cloud environments that multitask mode is currently local-only and disabled in Cloud Agents. This report is the UI side of that: the button is missing entirely, so there is no way to start multitasking from the cloud agent view (and no disabled/explanation state either).

Steps to Reproduce

  1. Open a Cloud Agent that is already running (example: NetanelH2/mentor, agent titled App explanation clarity”, branch cursor/simplify-settings-copy-a77f, PR #697)
  2. While it is working, send two follow-ups so they sit in Queued
  3. Look at the Working / Queued bar
  4. Observe: 1 Working, 2 Queued, Stop All is visible, Start Multitasking is not

Expected Behavior

Same as local agents: when there is queued work, show Start Multitasking (or a clear disabled state that says cloud agents do not support multitasking yet). Queued follow-ups should be startable in parallel if/when cloud supports it.

Version Information

  • Client: Cloud Agent on NetanelH2/mentor (web / Cursor cloud agent view, not the iOS app)
  • Agent title: App explanation clarity
  • Branch: cursor/simplify-settings-copy-a77f
  • PR: #697
  • State in screenshot: 1 Working (“Review Settings titles demo video”, cloud icon), 2 Queued, Send follow-up, priority High, footer shows Cloud
  • Cursor latest as of 2026-08-17

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hi @Netanel What you’re seeing is expected today. On a local agent, queued follow-ups can show Start Multitasking so that work can run in parallel. That control is not available on Cloud Agents yet, so the Working / Queued bar only shows the serial queue (and Stop All). Follow-ups still run, they just go one after another.

Two options that work now:

  1. Leave the follow-ups queued and let the Cloud Agent drain them in order.
  2. For work that should run in parallel, start separate Cloud Agents, or ask the agent to spawn subagents in the prompt. The queue-tray control itself is not wired up for cloud yet.

Team is aware of this gap!
