## What iphone-duo does, in the publisher's words

Adapt, audit and design-review iOS apps for iPhone Duo, Apple's foldable iPhone (announced 2026-09-09, ships on iOS 27.1). The Duo APIs are newer than any current model's training data, so an agent asked about them invents plausible symbol names. This plugin replaces that guesswork with references that carry a provenance tag on every symbol.

Three components:

- Claude Code or Codex for a native plugin install (options 2 and 3). Codex packaging and skill discovery were checked with Codex CLI 0.157.1. The skills also work through the Agent Skills CLI in Claude Code, Cursor, Codex and other supported hosts: see option 1.
- macOS with Xcode Command Line Tools for the toolchain gate (xcodebuild -version, xcrun --sdk iphoneos --show-sdk-version). The grep audit itself runs anywhere; the toolchain gate is what decides whether iOS 27.1 APIs may be written yet.
