A React Native and Expo add-on for adapting iPhone apps to Apple's foldable iPhone Duo. It provides fold-aware layouts, native tabs and toolbars, safe-area handling, and support for different screen poses.

Use it to build or update an Expo app for Duo, including list-and-detail layouts, split views, tabletop layouts, and fold-specific checks.

A foldable screen can place content across the hinge or leave it under device bars. This helps identify and handle those layout and iOS launch problems.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

duo-craft scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
