What's Wrong?

Description

Scheduled routines (CCR) get stuck indefinitely on the "Setting up a cloud container" phase, specifically at the "Clone repository" step. No cancel/stop button is available in the UI.

Steps to reproduce

1. Create a scheduled routine via /schedule with a private GitHub repository as source
2. Trigger a manual "Run now"
3. UI shows: Setting up a cloud container → Clone repository → hangs indefinitely

Actual behavior

Hangs on "Clone repository" for 30+ minutes. Starting a second run also hangs. Multiple users reported the same issue in the same ~2 hour window (2026-05-24 ~10:55–12:00 UTC), suggesting a platform-wide outage.

Details

• Repository size: ~1.1 MB (very small), PAT confirmed valid with full repo scope
• Environment: Default (anthropic_cloud)
• Routine ID: trig_01BNTRYgHrFSfeoHMXCq1dbS

Additional notes

No cancel/stop action exists in the RemoteTrigger API, making it impossible to abort stuck runs programmatically. A cancel button in the UI would help.

What Should Happen?

The routine should complete the "Clone repository" step within 1-2 minutes and proceed to execute the agent prompt. If cloning fails, it should show an error and allow the user to retry or cancel the run.
