Creates a complete two-player, one-phone SwiftUI game for iPhone Duo, Apple's foldable, where each player gets half the screen in every pose (closed on the outer display, open on the inner display, upright or sideways, partly folded). Use when someone wants to start a new two-player game or shared-screen app from scratch (a new Xcode project), or runs /duo-new recipe-two-player-game. For an existing app, use duo-shared-screen instead. Covers EvenSplit (GeometryReader plus AnyLayout), per-half…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# recipe-two-player-game This recipe makes a new Xcode project: a two-player race for one iPhone Duo. Each player gets half the screen. Targets appear in each half; a player taps their own. A miss locks that player out for a moment. First to the goal wins, then both tap Rematch. The game is a placeholder. The value is the frame around it: two halves that always show, touches judged in each half's own coordinates, rules you can test on the Mac in seconds, and UI tests that pass on the Duo simulator. Labels: *measured* means we ran it, on the iPhone Duo simulator (iOS 27.1, closed, outer display) unless the line names another one. *Unverified* means we could not check it. Everything else links to Apple. Full source list: [reference/sources.md](https://github.com/Kimeur/duology/blob/main/reference/sources.md). Use a different skill when: - the app already exists: use `duo-layout` (EvenSplit) and `duo-shared-screen`; - one person uses the app: start from `duo-start`. ## 1. Create the project …

How to install
mdr add kimeur/duology/recipe-two-player-game@sha256:ef8e0616f17fc5b0The line at the top of this page pins the label git:20261020.845400b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
