Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When I use agent he telling plan then i approve it . he again telling plan and saying he will start it. but does not. then i again tell him to start it he does not. Couple times and please please he starting.. I am not sure maybe we tring it do it paralell or some but some error or someelse.

Steps to Reproduce

I am not sure how. maybe hit limit almost to selected model then use auto.

Expected Behavior

I except he will start do plan.

Screenshots / Screen Recordings

Operating System

Windows 10/11

Version Information

IDE: 2.5.26

For AI issues: which model did you use?

Mode: Auto. Because Claude 4.6 got limit

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report and the screenshot. I can see the agent keeps restating the plan instead of actually executing it.

A couple things to try:

  1. Start a new chat. Once the agent gets into this loop, it tends to keep looping in the same conversation.
  2. Try a different model directly, not Claude. Instead of Auto, manually pick something like Gemini 3 Flash or GPT-5.2. Auto routing with fallbacks can sometimes cause this behavior.

To dig deeper, I’ll need the Request ID from the chat where this happens. Click the three-dot menu at the top of the chat, then select “Copy Request ID”.

Let me know how it goes.
