⚠️ The Shortcuts Save File action doesn’t work for me on macOS 15 Sequoia, even in a trivial example. It asks for permission, then fails anyway. Giving Shortcuts Full Disk Access didn’t make any difference. Happens with folders other than Desktop too.

Alert asking: Allow “Save File” to access your “Desktop” folder?

Alert saying: You don't have permission. The file couldn’t be opened because you don’t have permission to view it.
