What is ios-hig-prototype?

An iOS interface prototyping tool that produces a working interactive HTML mockup styled according to Apple’s Human Interface Guidelines, the design rules for Apple apps. It includes common phone interface parts such as navigation bars, tab bars, lists, and modals.

Use it to create a single-file HTML prototype of an iPhone interface with an iOS-style device frame and standard screen elements.

It lets you inspect and interact with an iOS screen concept before building the native app.

Security

Grade A, and why

ios-hig-prototype 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 2d 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.
