In the Claude Desktop Routines Calendar view, remote triggers that use multi-value cron hour fields (e.g., 0 9,12,16 * * 1-5) do not appear on the calendar, even though they are enabled and scheduled.

Root Cause

In the Claude Desktop Routines Calendar view, remote triggers that use multi-value cron hour fields (e.g., 0 9,12,16 * * 1-5) do not appear on the calendar, even though they are enabled and scheduled.

Description

In the Claude Desktop Routines Calendar view, remote triggers that use multi-value cron hour fields (e.g., 0 9,12,16 * * 1-5) do not appear on the calendar, even though they are enabled and scheduled.

Steps to Reproduce

  1. Create a remote trigger with a cron expression containing a comma-separated hour field, e.g. 0 9,12,16 * * 1-5 (runs at 9:00, 12:00, and 16:00 on weekdays)
  2. Open Claude Desktop → Routines → Calendar tab
  3. Look at today's scheduled routines

Expected Behaviour

The trigger should appear 3 times on the calendar for today (once per scheduled hour).

Actual Behaviour

The trigger does not appear at all in the Calendar view. Other triggers with simple cron expressions (e.g., 16 8 * * 1-5) show correctly.

The trigger does appear when clicking the "All" tab, and the API confirms it is enabled with a valid next_run_at timestamp.

Environment

  • Claude Desktop on Windows 11
  • Trigger confirmed active via API (RemoteTrigger list action)

extent analysis

TL;DR

The issue is likely due to the calendar view not properly handling multi-value cron hour fields, and a potential workaround is to modify the cron expression to use separate triggers for each hour.

Guidance

  • Verify that the issue is specific to the calendar view by checking if the trigger appears correctly in other views, such as the "All" tab, and confirm its status via the API.
  • Attempt to create separate triggers for each scheduled hour (e.g., 0 9 * * 1-5, 0 12 * * 1-5, and 0 16 * * 1-5) to see if they appear correctly on the calendar.
  • Check if there are any existing issues or limitations in the Claude Desktop documentation or community forums related to handling multi-value cron expressions.
  • Consider reaching out to the Claude Desktop support team for further assistance, as the issue may be specific to the application's implementation of cron expressions.

Example

No code snippet is provided, as the issue is related to the application's handling of cron expressions rather than a specific code implementation.

Notes

The issue may be specific to the Claude Desktop application on Windows 11, and it is unclear if this issue affects other platforms or versions. Further investigation is needed to determine the root cause and a permanent fix.

Recommendation

Apply workaround: Create separate triggers for each scheduled hour, as this is a more straightforward and reliable approach until the issue with multi-value cron hour fields is resolved.
