Migration Helper

This handles the tricky part of Convex schema changes when you can't just add an optional field and call it a day. It walks you through the widen-migrate-narrow pattern for breaking changes like adding required fields, changing types, or restructuring nested data into relations. The skill provides batch processing patterns, cron-based scheduled migrations, and dual-write strategies so your app stays up while data transforms in the background. Comes with verification queries and a migration checklist, which honestly saves you from the paranoia of wondering if you migrated every record. If you're moving fast on Convex and need to refactor your schema without downtime, this gives you the playbook.
