Slow execution of any terminal command initiated by LLM

Bug Reports
1

Where does the bug appear (feature/product)?

Cursor CLI

Describe the Bug

I can observe very slow execution of virtually any terminal command that is executed by LLM inside chat. The problem doesn’t appear if I try manually execute command inside cursor terminal or any other dedicated terminal. All network logs complete in the range of milliseconds.

Steps to Reproduce

There wasn’t any specific change that was applied to introduce this.

Expected Behavior

AI assisted commands should execute at roughly the same time of manual execution.

The bug was not present in at least one version from the last two weeks, but it has reappeared and is occurring consistently since then.

Issue was resolved after I installed Cursor v1.5. Then got popup with update, updated to:
Version: 1.6.42
VSCode Version: 1.99.3
Commit: 5911e9593196a000b1c00553aaf03b0b32042b90

V8: 13.2.152.41-electron.0
OS: Darwin arm64 25.0.0

AI assisted terminal commands were running as they normally should. After 30-40 minutes I have the same problem again.

And for me it’s so slow… Downgrade to 1.5 version solved this problem for me
