Cowork deep link drops the q prompt when folder is also set
On macOS, claude://cowork/new?q=Studio-Status works as documented. A new Cowork session opens and the composer is prefilled.
As soon as I add a folder, the prompt is gone:
open "claude://cowork/new?q=Studio-Status&folder=/Volumes/ProjectVault/Musik%20Projekte/Projekte"The session opens, the folder confirmation dialog shows up, I confirm it, and the folder is attached correctly. The composer stays empty.
I also tried the parameters in the other order, and prompt instead of q. Same result every time. My guess is that confirming the folder rebuilds the session and the prefilled text is dropped on the way.
Expected: folder attached and composer prefilled, the way the docs describe.
Workaround for anyone hitting this from a launcher like Alfred: open the link with folder only and put the prompt on the clipboard in a second step, then paste it after the dialog.
