modernize

Find legacy patterns in your codebase and get the migration path for each one.

Shorthand for /axiom:audit modernization — same agent, fewer keystrokes.

What This Command Does

Launches the modernization-helper agent. It reports each legacy pattern with the modern equivalent and how to get there, so you can adopt incrementally rather than facing an all-or-nothing rewrite.

What It Checks

1. ObservableObject / @Published – the @Observable macro replacement, and what changes about view updates
2. @StateObject / @ObservedObject – when these become @State and @Bindable
3. Deprecated SwiftUI APIs – still-compiling calls that have a current replacement
4. UIKit patterns with a modern equivalent – including scene-lifecycle migrations
5. Migration order – which changes are safe in isolation and which have to move together

Usage

/axiom:modernize
