@16francej — recommend closing this PR as superseded by #2142, the broader target for complete Cursor support. This patch only changes setup allowlisting and help text; it does not generate, install, own, or uninstall Cursor skills, and unresolved security problems remain. Preserve contributor attribution and the original Cursor setup intent, but not this implementation.

Thanks for this, @xidongc. The fix is now on main: setup accepts --host cursor (already on main as of v1.91.16.0). Closing as superseded; if you still see the problem on the latest gstack, please open an issue with ./setup --status output.
