What's Wrong?

A Cloud Routine created via http_api (not through the in-app "New routine" flow) cannot have its cron schedule changed through either supported path:

1. Programmatically: calling update_trigger with a new cron_expression on such a routine is refused with: "this routine was created via 'http_api', not by an agent. Agents can only update routines they created (via create_trigger)."

1. Via the claude.ai/code/routines UI: opening the routine's detail page shows the schedule as plain, non-interactive text ("Runs every Sunday at 11:00 AM") — no click target, pencil icon, or edit control was found after trying: the card's "⋮ → Edit" menu (which just opens the same read-only detail page), clicking directly on the day/time text, clicking the History filter icon, and zooming the page to check for a hidden hover-only icon.

As a workaround, we tried creating a new routine via create_trigger (same prompt, correct schedule) intending to delete the old one afterward. The new routine was created with sources: [], outcomes: [], allowed_tools: [], and no MCP connectors — i.e. no repository access and no basic tool permissions, so it would not have functioned. We deleted it immediately, before any run.

Routines affected (same account):

• trig_018m7xjheBf7Zw9x6F4Ln9sH ("سلطان - توصيات النمو الأسبوعية")
• trig_012eqsHPrBFUf7LRxZhN5b4h ("سلطان - تقرير التحليلات الأسبوعي")
• trig_01N5NoF6FGwZpTDWFZRXnSg4 ("سلطان")

What Should Happen?

Either the routines UI should expose an editable schedule control for http_api-created routines, or update_trigger/create_trigger should support changing an existing routine's schedule while preserving its repository sources, tool permissions, and MCP connectors.

Error Messages/Logs

update_trigger error: "this routine was created via 'http_api', not by an agent. Agents can only update routines they created (via create_trigger)."

Steps to Reproduce

1. Create a Cloud Routine via the http_api (e.g. through this project's Telegram relay flow), not through the in-app "New routine" button.
2. Go to claude.ai/code/routines, open that routine's detail page.
3. Try to change its schedule ("Repeats" section) — the day/time text is not clickable, and no edit control is found via the card's "⋮ → Edit" menu either.
4. As an alternative, from an interactive session call update_trigger on that routine's ID with a new cron_expression — it is rejected with an ownership error.
5. As another alternative, call create_trigger to create a brand-new routine with the same prompt and the desired schedule — the new routine is created but with empty sources, outcomes, and allowed_tools, so it has no repository access or basic tool permissions.
