[BUG] cursor <-> claude code integration does not work from inside tmux

Exporting TERM_PROGRAM=cursor should make it pick up that it's in Cursor. cursor will also need to be in the path for it to work

Just tried it, didnt work.

(cursor is in the path)

Ah, ok. I'm seeing an error:

! cursor --list-extensions
  ⎿  Unable to connect to VS Code server: Error in request.
     Error: connect ENOENT /tmp/vscode-ipc-13b05293-93fa-4a98-8a0d-d62186acfa94.sock

I do see the extensions in my setup

     anthropic.claude-code

just adding on here that I am seeing similar issues in vs code insiders, vs code release version works fine. export TERM_PROGRAM=code-insiders does solve the issue though.

Update: this stopped working for some reason, not sure why.

Same here

@ramarnat - are you running tmux in ghostty or in cursor's terminal? you have to run it in cursor terminal (without tmux) at least once to install. After that it should work.

For folks for who it stopped working we should have a fix today.

woot! Seems to be working now.

This is in the cursor ide terminal

I still have the issue, its working in normal terminal but not in tmux session the it does not find the ide.

It seems from the latest claude-code version 1.0.56, this suddenly doesn't work. It was working yesterday (or maybe two days ago)

cc version 1.0.62 -> Same issue is back
