Agent interrupted mid-task

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Starting today, I’m having issues where the agent stops working mid-workflow. For example, it adds a markdown heading and then stops before adding text below it. Or creates a to-do list, and gets interrupted right before it starts working on the next item. When this happens, the prompt interface returns to a normal state, so I can prompt it to “Continue working.” to get it to keep going. But this has happened multiple times with different models in the last couple hours.

Steps to Reproduce

Prompt claude-4-sonnet thinking or claude-4.1-opus thinking on MAX Mode with a long-running task.

Expected Behavior

The agent continues working until it finishes its todo list and/or response.
