Review Data Release
Use this skill before shipping migrations, backfills, or schema/data-shape changes.
Checklist
- Migration safety and rollback strategy
- Data mapping integrity and orphan risk
- Backfill safety and idempotence
- Release sequencing and post-deploy verification queries
Rails Touchpoints
- Validate migration reversibility and lock risk (table size/index impact).
- Confirm model/schema compatibility during rolling deploys.
- Verify background backfills are idempotent and retry-safe.
- Ensure strong params and serializers align with schema changes.
- Provide concrete post-deploy checks (
db:migrate:status, verification queries).
Context Discipline
- Start from changed migrations/models/jobs and only expand if coupled systems are affected.
