If you're hitting SwiftData's limitations in a Swift project and need to move to SQLiteData, this handles the migration work. It's part of the axiom toolkit from charleswiltgen, which has nearly 1,000 GitHub stars and has passed security audits from Gen Agent Trust Hub, Socket, and Snyk. The skill focuses specifically on the data migration path rather than being a general database tool. You'd reach for this when SwiftData's constraints are blocking you and you need direct SQLite access without rewriting your data layer from scratch. Nearly 200 installs since January suggests others have hit the same wall.
