What's Wrong?

Summary

Scheduled tasks (cron-based) created via Cowork do not execute at their scheduled times if the Claude Desktop app is not running. Instead, all pending tasks queue up and fire simultaneously the moment the app is next launched.

Steps to Reproduce

1. Create recurring scheduled tasks in Cowork (e.g., daily cron at 5:30 AM)
2. Close the Claude Desktop app (or let it auto-quit after the 5-minute idle timeout)
3. Wait past the scheduled execution time
4. Open the Claude Desktop app

Expected Behavior

Scheduled tasks should run at their configured cron times regardless of whether the desktop app is open. These are server-side scheduled tasks — they should not depend on the client app being active.

Actual Behavior

Tasks do not run while the app is closed. Upon opening the app, ALL pending tasks fire simultaneously. Evidence from my task list:

• ai-dev-daily-brief (scheduled ~5:38 AM) — lastRunAt: 2026-04-06T06:26:23.505Z
• ai-war-brief (scheduled ~5:07 AM) — lastRunAt: 2026-04-06T06:26:23.524Z

Both tasks ran within 19ms of each other, clearly triggered by app launch rather than at their scheduled times.

Why This Matters

Combined with the 5-minute idle auto-quit (see #23092), this makes scheduled tasks essentially unusable for their intended purpose. There is no reliable way to keep the desktop app open long enough for scheduled tasks to fire, and the tasks won't run without it. This defeats the entire value proposition of scheduled/recurring tasks.

Environment

• Claude Desktop (latest version)
• Cowork mode (research preview)
• macOS

What Should Happen?

Scheduled tasks should run at their configured cron times regardless of whether the Claude Desktop app is open. These are scheduled tasks — they should execute server-side and not depend on the client app being active.

Both ran within 19ms of each other, clearly triggered by app launch rather than at their scheduled times.
