Prisma Next — Migration Review (Deployment + Concurrency)

Edit your data contract. Prisma handles the rest.

This skill is about reviewing migrations, not authoring them. It covers the questions that come up at deploy time and when multiple developers are landing migrations concurrently.

The skill teaches the system's mental model — what a ref is, what a marker is, what the migration graph is — and shows how to ask the system for its state. It does not prescribe rigid step-by-step procedures: most "review" questions are answered by understanding the model and querying the right thing. Rigid procedures are reserved for the rare case where there's literally one safe path.

When to Use

• User asks "what migrations will run when I merge this?" or "what's about to run on deploy?".
• User hit a concurrent-migration conflict (main advanced while their branch was open).
• User wants to wire up a staging / production ref so CI can deploy against it.
• User wants to run a migration against an environment that isn't the local dev DB.
• User asks about CI integration for migrations.
