Use when designing, adapting, implementing, or auditing an iOS app for iPhone Duo, including resizing, folding, vertical bars, reserved regions, state continuity, multiple scenes, camera behavior, and accessibility. Produce evidence-based readiness findings with SDK gates and fallbacks. Do not use for generic iPhone work without Duo or adaptive-layout requirements, Android foldables, Microsoft Surface Duo, Google Duo, or claims of Apple certification.
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 design and readiness Help an app keep its identity and functionality while its usable space changes. This skill works with any coding assistant that can read Markdown. Shell, browser, Xcode, and simulator tools are optional capabilities, not host-specific dependencies. When a tool is unavailable, provide the exact remaining check and keep its result unverified. ## Establish the target Before changing code, inspect the app's deployment targets, Swift language mode, selected Xcode/SDK, UI framework, scene configuration, and principal user flows. For design-only work, record any unknowns instead of choosing a deployment target for the user. Preserve existing platform support unless the user requests a change. Read [versions and sources](references/versions-and-sources.md) before proposing Duo-specific symbols. Refresh the official sources when implementation depends on their current availability. The source snapshot is dated September 17, 2026; it is not a claim about the SDK available in a future session. Keep three evidence categories separate: - Apple documentation or SDK declarations establish API contracts. …

How to install
mdr add fal3/claude-skills-collection/iphone-duo-design@sha256:23fb673db1769eb9The line at the top of this page pins the label git:20260917.7201e74, 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.
