As the first image shows, the app itself can detect the remote server's skill.

If we directly open the remote session, we can still see the skill:

But if we choose to start a session with new worktree, the skill becomes unreachable:

The at search is the same. It works perfectly if the session is already created or is a fresh and simple one.
But I will see the expected search result if the session begins with new worktree.

What steps can reproduce the bug?

Remote session + starting with New worktree.

What is the expected behavior?

The $ and @ work as expected.
