SwiftUI Pro, Paul Hudson's open-source agent skill, is trending on GitHub with about 5,200 stars. It gives Claude Code, Codex and Gemini a 12-file review checklist targeting the mistakes LLMs actually make in SwiftUI: deprecated API, invisible VoiceOver buttons and slow views. Here is how to install it, what it checks and where it falls short.

Ponytail turns your AI coding agent into the laziest senior developer in the room: before writing code it climbs a ladder from do not build it, to reuse it, to the standard library, to a native feature. Its own agentic benchmark reports 54 percent less code and 100 percent safety. Here is how it works, what the numbers do and do not show, and how to try it without regret.
