What issue are you seeing?

When using Codex Desktop with Cursor as the editor target, clicking file links (open-in-editor/file references) fails if any parent directory in the workspace path contains spaces.
Cursor opens multiple empty tabs, as if the path was split by spaces (for example: 2., Example, Projects).

What steps can reproduce the bug?

1. Set Codex Desktop editor target to Cursor.
2. Open a workspace whose path includes spaces, for example:

/Users/example/Dev/2. Example Projects/demo-repo

1. Click a file path link in Codex output.

What is the expected behavior?

Cursor opens the intended file path.

Additional information

Scope

• Reproduces only with Cursor target.
• Does not reproduce with non-Cursor editor targets.

Environment

• Platform: macOS
• App: Codex Desktop
• Editor target: Cursor

Additional context

This looks like path arguments are not being quoted/escaped correctly when launching Cursor from Codex Desktop.
