Diagnoses and resolves iCloud sync issues for CloudKit and iCloud Drive in Apple platform applications.
The axiom-cloud-sync-diag skill provides a systematic framework for debugging 'file not syncing' and CloudKit errors across iOS, iPadOS, and macOS development environments. It guides developers through mandatory first steps like checking ubiquity tokens and entitlements, provides structured decision trees for specific errors such as quota exhaustion or server record conflicts, and offers code-level solutions for common pitfalls in SwiftData and file coordination. By emphasizing configuration and connectivity verification over infrastructure assumptions, it significantly reduces the time required to resolve complex synchronization bugs.
