### Where does the bug appear (feature/product)?

Cursor IDE

### Describe the Bug

Applying changes via Cursor inspector overwrites current agent convo/session history.

Actual: The agent session history is cleared / overwritten — any conversation in progress is lost.

Impact: Applying a single inspector change wipes an active session, which breaks iterative inspect-and-apply workflows.

### Steps to Reproduce

Start a conversation with the Agent in Cursor.  
Open the built-in browser and navigate to a local dev server (e.g. localhost:5173).  
Use the Cursor Inspector to inspect a UI element.  
Click “Apply” to apply a prop change.

The agent session history is cleared / overwritten — any conversation in progress is lost.

Impact: Applying a single inspector change wipes an active session, which breaks iterative inspect-and-apply workflows.

### Expected Behavior

The change is applied to the source file; the current agent session (conversation history, in-progress work) is preserved.

### Operating System

MacOS

Hey, thanks for the detailed report. The repro steps and version info really help.

Repro: clicking Apply in Cursor Inspector either opens a new composer session the old one disappears from the view but stays in history, or it injects changes into the current one. In both cases, the active agent convo breaks. This is a bug on our side, I’ll file an internal ticket.

A couple questions for the ticket:

- In your case, is the old session actually deleted, or does the view just switch? Can you still find it in the Agents sidebar or chat history?
- Did you have any text in the input at the moment you clicked Apply?

Workaround for now: before clicking Apply in the inspector, keep the input empty and save the link to the current session via the Agents sidebar so you can return to it. I can’t share an ETA yet, if I get an update I’ll reply in the thread.

Hey @hotturnips,

Just following up like I said I would. The inspector Apply flow that was replacing your active agent session isn’t in Cursor anymore. The CSS Inspector was removed in 3.12, so on current versions that path can’t wipe an in-progress conversation.

If you’re still seeing an agent session get lost or replaced on the latest version from something else, let me know what you were doing at the time and I’ll take a look.
