The folder location is what connects these two apps. I copy it from Outloop and reveal it in Finder. The connection instructions are already inside. Keep this folder: creating another one with the same name would not give Claude the same context.

In Claude, I create a project using the folder Outloop just made. I review the permission for that folder and create the project. Then I check that Claude shows the local folder on this computer. That is the connection we need; a matching project name by itself is not enough.
