Agent skills for building iOS apps on iPhone Duo — Apple's first foldable iPhone, announced September 9, 2026.

Apple's developer material for iPhone Duo is now six Tech Talk videos, the Designing for iPhone Duo HIG page, the Prepare checklist, and the API reference. The last two landed after this repo started — the API reference corrected three claims, and the Prepare guide added several more. Both passes are reflected here.

These skills distill all of it into structured guidance an agent can act on, plus reference sheets for device facts and the full API surface.

Installs all eleven. The CLI detects your agent — Claude Code, Cursor, Copilot, Gemini and others — and puts them where that agent looks.

Useful flags:

# just one skill
npx skills add mirzaaghazadeh/iphone-duo-skills --skill iphone-duo-readiness

# user-level instead of project-level

cp -r iphone-duo-skills/skills/* ~/.claude/skills/

Each skill is a self-contained SKILL.md with YAML frontmatter, so it also works anywhere that reads plain Markdown instructions. Restart the session and the skills appear; invoke one by name or just describe the task.
