Axiom provides a comprehensive suite of battle-tested Claude Code skills, commands, and references specifically for modern xOS (iOS, iPadOS, tvOS, watchOS) development. It aims to streamline the adoption of new Apple technologies like Swift 6, SwiftUI, and Apple Intelligence, offering developers enhanced productivity and robust solutions for complex debugging and performance challenges.

How It Works

Axiom integrates as plugins within the Claude Code environment, offering specialized "skills" that are contextually suggested based on developer queries. This approach leverages Claude Code's AI capabilities to proactively deliver relevant commands and guidance, covering a wide spectrum of development tasks from UI implementation and performance tuning to data persistence and debugging. The system is designed to provide immediate, actionable assistance directly within the developer's workflow.

Quick Start & Requirements

Installation is performed within Claude Code by running /plugin marketplace add CharlesWiltgen/Axiom, followed by searching for and installing "axiom" from the plugin menu.
