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

# Duology

> Open-source (MIT) agent skills and Claude Code plugins for designing, building, testing and shipping native SwiftUI and UIKit apps on iPhone Duo, Apple's foldable iPhone with a 5.4-inch outer display and a 7.6-inch inner display. Built for Xcode 27.1 and iOS 27.1. A community project, not affiliated with Apple.

Start with the duo-start skill: it detects the app's setup and says which skill to load next. Each skill is a SKILL.md file with detail in its references/ folder. Every iPhone Duo API name in Duology is checked against the iOS 27.1 SDK; reference/api-index.md lists them with Apple's doc links, and its "Not in the SDK" section lists names that sound right but don't exist. Pick layouts by size class, never by UIScreen.main, device model or orientation.

## Start here

- [duo-start](https://raw.githubusercontent.com/Kimeur/duology/main/plugins/duology/skills/duo-start/SKILL.md): Entry point. Detects SwiftUI or UIKit, new or existing app and the SDK, runs a first pass, routes to the other skills.

How to install

The exact contents, by fingerprint

mdr add kimeur/duology/llms.txt@sha256:f289527969127970

The 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.
