What's Wrong?

Problem

When a scheduled Routine run gets stuck or runs unexpectedly long, there is no way
to kill it — neither from the Routines UI (no Stop/Cancel button on a running run)
nor programmatically (TaskStop only works for tasks spawned within the current session).

Current behavior

• The Routines UI shows the run as active but offers no cancel action.
• TaskStop requires a task_id that is not exposed for remote scheduled sessions.
• The run from May 1 has been stuck for 3+ days with no way to terminate it.

Expected behavior

• A Stop / Cancel button on any active run in the Routines UI.
• Or: expose the task_id of a running routine session so it can be stopped via TaskStop.

Environment

• Claude Code desktop app / Routines feature
• OS: Windows 11 Pro

What Should Happen?

There should be an option to kill a running routine.

This one is really frustrating and I'm currently having the same issue.
The problem is, my routine run keep draining my usage limit, to the point it reached 100%, or it timed out in 30 minutes first.

Hello, any update on this?

[SnowAIGirl]

This is exactly the problem I ran into too — no way to kill a stuck session once it is running. I built claude-tmux-dog (https://github.com/SnowAIGirl/claude-tmux-dog) primarily to solve this: claude-tmux-dog stop <name> and claude-tmux-dog restart <name> give you CLI-level control over session lifecycle. It also recovers from API errors, manages quota resets, watches context window usage, and supports multiple concurrent agents. Basically a process manager for Claude Code sessions.
