Data Sync Workflows

Use this skill when data moves between systems and the application must preserve correctness across retries, partial failure, and repeated runs.

Design Questions

• What is the source of truth for each field?
• Is the sync full, incremental, event-driven, scheduled, or manual?
• What is the stable identity key across systems?
• What checkpoint or cursor proves where the last successful run stopped?
• Can the operation be retried safely?
• What does a partial success mean?
• How will operators see what changed, failed, skipped, or needs repair?
