What is swiftui-agent-skill?

A code-review skill for SwiftUI, Apple's framework for building app interfaces with Swift. It focuses on modern APIs, maintainability, and performance.

Use it to review SwiftUI code for iPhone, iPad, Mac, Apple Watch, or other Apple-platform apps.

It helps identify SwiftUI code that may be harder to maintain or may perform poorly as an app grows.

Security

Grade A, and why

swiftui-agent-skill 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 yesterday.

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.
