Axiom Swiftdata Migration Diag

This is a diagnostic tool for tracking down SwiftData migration bugs in iOS apps, the kind that crash in production but work fine in the simulator. It operates on a solid premise: most migration failures come from missing models in VersionedSchema or borked relationship inverses, not actual SwiftData bugs. With 948 GitHub stars and 177 installs, it's clearly solving a real pain point. The skill provides red flags to watch for and presumably guides you through the debugging process. If you've ever shipped a Core Data or SwiftData migration that exploded on user devices, you know exactly why this exists.
