Chat tab is renamed by first prompt when tab was previously renamed by user

[Lance_McQuiddy]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When the user add a chat tab in Cursor Agent frame and renames it, cursor then overwrites the user’s custom name and changes the tab name based upon the first prompt.

If the user renames a chat tab, the first prompt should not overwrite the title of the chat tab.

Steps to Reproduce

1. Create “New Chat” tab. I use the “+” on the top right of the Agent frame.
2. Rename the tab. I do RMB and select “Rename Chat”
3. Enter a prompt such as “When I add a New Chat tab in Cursor’s Agent frame and rename it, cursor then overwrites my rename when I submit the first prompt. This feels like a bug.”

The result is the tab is now named “Cursor chat tab renaming bug”

Expected Behavior

Tab name should not change.

Operating System

Windows 10/11

Hi Lance!

This is a confirmed bug. When you rename a chat tab and then send the first message, the auto-rename logic doesn’t account for the fact that you already set a custom name, and it overwrites it.

This was also reported in this thread, and our team is aware of it.

For now, the workaround is to rename the chat after sending the first message. The auto-rename only triggers on the first message, so any name you set afterward will stick.

Thank you for the confirmation. I searched for rename, but did not find another ticket. Appologies for the duplicate.
