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
# iPhone Duo displays, hinge, scenes and cameras
Code: `references/displays-code.md`. Availability: `references/api-availability.md` —
the hinge APIs, `CameraCaptureAccessory`, the direction coordinator and the physical
front camera types need the **iOS 27.1 SDK**, which ships with Xcode 27.1;
`sceneAccessory`, `onAvailabilityChange`, `UISceneAccessory` and
`UIWindowScene.ActivationAction` exist earlier. The hinge reaches you only through
`UIHingeInteraction` / `onHingeChange`: there is no trait, no notification and no
`UIDevice` property. StandBy cannot be verified in the iPhone Duo simulator
(Xcode 27.1 known issues 187708663, 187708767). Which half
carries the outer display and the inner camera, how each pose faces, and what each
camera can do: `references/device-geometry.md`.
## Hinge (Tech Talk 111464, 0:49–2:35)
- SwiftUI `onHingeChange { previous, context in … }`; UIKit
`UIHingeInteraction { _, update in … }` added to a view with `addInteraction`.
- Reports a status — closed, partially open, fully open (UIKit also `unknown`) — and
a continuous angle (`UIHinge.angle` is in radians; the SwiftUI sample uses `Angle`).

How to install
mdr add alexey1312/iphone-duo-agent-skill/iphone-duo-displays@sha256:f713d695a6da58acThe line at the top of this page pins the label git:20261005.bab8398, 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.
