Hey, thanks for the report. The Agent is getting stuck - it looks like a network or extensions issue.

Quick checks:

  1. Extensions check:

    • Run cursor --disable-extensions in the terminal
    • A new Cursor window will open
    • Don’t open a repo, just try the Agent in an empty window
    • If it works, the issue is with extensions

  2. HTTP/2:

    • Cursor Settings CMD+, > search “HTTP/2”
    • Enable “Disable HTTP/2”
    • Restart Cursor

  3. Network diagnostics:

    • Cursor Settings > Network > Run Diagnostics
    • Share the results

If this doesn’t help, please share:

  • The Request ID of the stuck request (chat menu on the right > Copy Request ID) - Getting a Request ID | Cursor Docs
  • A screenshot of the console during the hang (Help > Toggle Developer Tools > Console) - look for “ETIMEDOUT” or “unavailable” errors
  • Your list of installed extensions

Let me know how it goes.
